A To guide you to the correct lane
B To help you keep the correct distance from the vehicle in front of you
C To inform you of the distance to the next exit
D To make you aware of how fast you're going
Correct Answer: D To make you aware of how fast you're going
Explanation: These lines are a device often found on the approach to a roundabout or a dangerous junction. They become closer together as you approach the hazard, warning you to slow down.
A Flashing amber
B Flashing green
C Steady amber
D Steady red
Correct Answer: C Steady amber
Explanation: Puffin crossings have infra-red sensors that detect when pedestrians are crossing and hold the red traffic signal until the crossing is clear. The use of a sensor means there's no flashing amber phase, as there is with a pelican crossing; the lights follow the same sequence as traffic lights.
A Continue at the same speed, the ambulance will move around you
B Move out of the way as soon as it's safe to do so
C Speed up to get away
D Stop immediately
Correct Answer: B Move out of the way as soon as it's safe to do so
Explanation: When an emergency vehicle is behind with its blue lights flashing, you must remain calm and look ahead for a safe place to move over to let it pass. If you're waiting at red traffic lights, don't attempt to clear the way by driving past the red light; this is both dangerous and a traffic offence.
A To alert others of your presence
B To force other road users to stop
C To get the attention of road users you recognise
D To let other drivers know they've annoyed you
Correct Answer: A To alert others of your presence
Explanation: You mustn't use a vehicle's horn between 11.30 pm and 7.00 am in a built-up area or when the vehicle is stationary, unless another moving vehicle poses a danger. The horn should be used to alert other road users to your presence.
A Stop behind the line, then slowly creep forward to get a better view
B Stop beyond the line
C Stop only if there is another vehicle behind you
D Stop only if you're turning right
Correct Answer: A Stop behind the line, then slowly creep forward to get a better view
Explanation: At blind junctions, there's often a 'stop' sign. The 'stop' sign has been put there because the view into the main road is poor. You must stop because it won't be possible to assess the situation on the move, however slowly you're travelling.
A To allow them to see better
B To be more visible
C To give way to you
D To prevent a flat battery
Correct Answer: B To be more visible
Explanation: A motorcycle can be lost from sight behind another vehicle. The use of the headlight helps to make it more conspicuous and therefore more easily seen.
A Because motorcycles aren't fitted with mirrors
B To check their blind spot
C To counterbalance the turn and stay upright
D To see who is following them
Correct Answer: B To check their blind spot
Explanation: If you see a motorcyclist take a quick glance over their shoulder, this could mean they're about to change direction. Recognising a clue like this helps you to be prepared and take appropriate action, making you safer on the road.
A They can cause motorcycles to slide
B To allow the motorcyclist to continue riding at the same speed
C To avoid possible punctures
D To avoid splashing nearby pedestrians
Correct Answer: A They can cause motorcycles to slide
Explanation: Motorcyclists will be checking the road ahead for uneven or slippery surfaces, especially in wet weather. They may need to move across their lane to avoid road-surface hazards such as potholes and slippery metal drain covers.
A Lorries are longer than cars
B Lorries are slower than cars
C Lorries sometimes swerve unexpectedly
D Lorry drivers tend to be unpredictable
Correct Answer: A Lorries are longer than cars
Explanation: It takes more time to overtake a long vehicle than a small one, such as a car. Before overtaking, you need to be able to see far enough ahead to know that you have the space and time to complete the manoeuvre safely. Hazards to watch for include oncoming traffic, junctions, bends or dips (which could restrict your view), and any signs or road markings prohibiting overtaking.
A Any, provided it isn't overtaking
B LGVs
C Learner drivers
D Motorcycles only
Correct Answer: A Any, provided it isn't overtaking
Explanation: On a motorway, all traffic should use the left-hand lane unless overtaking. When overtaking a number of slower vehicles, move back to the left-hand lane when you're safely past. Check your mirrors frequently and don't stay in the middle or right-hand lane if the left-hand lane is free.
A Driving at the speed limit
B Only buses may use them
C Only emergency vehicles may use them
D Overtaking
Correct Answer: D Overtaking
Explanation: You should keep to the left and only use the centre or right-hand lanes if you're passing slower-moving traffic.
A Emergency services can easily locate you
B Mobile phone signal is often poor near motorways
C You can talk directly to a garage
D Your mobile phone's battery might die
Correct Answer: A Emergency services can easily locate you
Explanation: On a motorway, it's best to use a roadside emergency telephone so that the emergency services are able to locate you easily. The nearest telephone is indicated by an arrow on marker posts, which are placed every 100 metres along the edge of the hard shoulder. If you do use a mobile phone, the emergency services will want to know your exact location. Before you call, find out the number on the nearest marker post; this will tell the emergency services your exact location.
A Just before a junction
B On a downward hill, on a motorway
C On an upward hill, on a motorway
D On the hard shoulder
Correct Answer: C On an upward hill, on a motorway
Explanation: Large, slow-moving vehicles can hinder the progress of other traffic. On a steep gradient, an extra crawler lane may be provided for slow-moving vehicles to allow faster-moving traffic to flow more easily.
A By street lighting
B By the presence of single or double yellow lines
C Hazard warning lines on the road tell you
D The presence of pedestrian islands is an indication
Correct Answer: A By street lighting
Explanation: There's usually a 30 mph speed limit where street lights are less than 185 metres (600 feet) apart.
A They give orders
B To give information
C To give warnings
D To provide directions
Correct Answer: C To give warnings
Explanation: Look at each sign that you pass on the road, so that you don't miss any warnings, orders or information. The shape of the sign will tell you its purpose: triangular signs warn, circles give orders and rectangles inform.
A Continue if the way is clear
B Continue if there are no crossing pedestrians
C Prepare to go
D Stop behind the line
Correct Answer: D Stop behind the line
Explanation: As you approach traffic lights that have been on green for some time, anticipate that they'll soon change. Check your mirror so that you know what traffic is behind you and how far away it is. If the lights change to steady amber, you should stop behind the stop line. If you're so close to the stop line when the lights change that to stop may cause a collision, you should continue. You'll only know the risk from traffic behind if you use your mirrors as you approach the lights.
A No one
B Vehicles going straight
C Vehicles turning left
D Vehicles turning right
Correct Answer: A No one
Explanation: When traffic lights are out of order, you should treat the junction as an unmarked crossroads. Be cautious, as you may need to give way or stop. Look for traffic attempting to cross the junction, unaware that it doesn't have priority.
A When a car ahead is indicating left
B When passing a queue of traffic
C When passing a slow-moving maintenance vehicle (10 mph or less)
D When you need to pass a vehicle with a trailer
Correct Answer: C When passing a slow-moving maintenance vehicle (10 mph or less)
Explanation: You may cross the solid white line to pass a stationary vehicle or to pass a pedal cycle, horse or road maintenance vehicle if it's travelling at 10 mph or less. You may also cross the solid white line to enter a side road or access a property.
A Anytime on a dual carriageway or motorway
B As you near a motorway exit you'll be taking
C In slow moving traffic on dual carriageways and motorways
D When the right-hand lane of a dual carriageway is being used by slower vehicles
Correct Answer: C In slow moving traffic on dual carriageways and motorways
Explanation: You should normally overtake on the right, but there are some occasions when you may overtake on the left. These include when you're driving on a dual carriageway or motorway and the traffic is moving slowly in queues, or when a vehicle ahead is positioned to turn right and there's room to pass on the left. On dual carriageways or motorways, don't overtake on the left if traffic is flowing freely.
A They provide a wider field of vision
B To allow you to better see traffic behind you
C To assist you on motorways and dual carriageways
D To assist you when checking your blind spot
Correct Answer: A They provide a wider field of vision
Explanation: A convex mirror gives a wide view of the scene behind. However, it won't show you everything behind, or to the side of, your vehicle. Before you move off, look over your shoulder to check for anything that's not visible in the mirrors.
A Avoid delays by overtaking as soon as possible
B Drop further back in case they need to manoeuvre around potholes
C Ensure you're visible in their mirrors by staying close
D Keep traffic moving by maintaining the usual two-second gap
Correct Answer: B Drop further back in case they need to manoeuvre around potholes
Explanation: Potholes and bumps in the road can unbalance a motorcyclist. For this reason, a rider may swerve to avoid an uneven road surface. Knowing what motorcyclists may do will help you to make allowances for them.
A Be patient and expect their reactions to be slower than yours
B Expect the driver to cause an incident and stay alert
C Overtake as soon as possible
D Stay close behind in case they need help
Correct Answer: A Be patient and expect their reactions to be slower than yours
Explanation: You must show consideration to other road users. The reactions of elderly drivers may be slower and they might need more time to deal with a situation. Be tolerant and don't lose patience or show your annoyance.
A Flash your headlights at the car to signal your intention to overtake
B Leave the headlights on dipped beam
C Overtake the car when it's safe to do so, then switch your headlights to full beam
D Switch your headlights to full beam, then overtake
Correct Answer: C Overtake the car when it's safe to do so, then switch your headlights to full beam
Explanation: To prevent your headlights from dazzling the driver of the car in front, wait until you've overtaken before switching to full beam.
A Driving with new tyres
B Driving with over-inflated tyres
C Driving with part-worn tyres
D Driving with under-inflated tyres
Correct Answer: D Driving with under-inflated tyres
Explanation: If your tyre pressures are lower than those recommended by the manufacturer, there will be increased rolling resistance. To overcome this, the engine will have to work harder, resulting in increased fuel consumption. Check your tyre pressures at least once a week.
A You might be less alert
B You might be more alert
C You might drive faster than you realise
D You might drive slower than you realise
Correct Answer: C You might drive faster than you realise
Explanation: After driving at motorway speeds for some time, a driver's judgement of speed may be affected. Having left a motorway, it's important that drivers frequently check their speedometer to avoid driving faster than they realise.
A Cancel your left-turn signal
B Ensure no vehicles are overtaking on the right
C Ensure there are no cyclists riding on your left
D Select first gear
Correct Answer: C Ensure there are no cyclists riding on your left
Explanation: In traffic, cyclists often filter past on the left of slow-moving queues or stationary vehicles. Before making a left turn, you should check your nearside and, if necessary, hold back until you can turn without cutting across a filtering cyclist.
A Leave at the next exit
B Move on to the hard shoulder
C Move to the middle lane
D Slow down
Correct Answer: C Move to the middle lane
Explanation: This sign on the overhead gantry will be accompanied by flashing amber lights. The arrow directs you to move into the next lane. There might not be any visible signs of a problem ahead, but there might be queuing traffic or another hazard that you can't yet see.
Correct Answer: A Accelerator
Explanation: Dual accelerators aren't normally fitted to training vehicles. If one is fitted, it must be removed while the vehicle is being used for a driving test.
A Additional manoeuvres must be carried out in the extended test
B It's twice as long as the standard test
C Its duration is 30 minutes more than the standard test
D There are two examiners in the extended test
Correct Answer: C Its duration is 30 minutes more than the standard test
Explanation: The extended test takes about 70 minutes and is assessed to the same level as the standard driving test for learner drivers.
A Devise an effective learning plan for each student
B Scold them for not progressing
C Test their theory knowledge regularly
D Treat each student the same
Correct Answer: A Devise an effective learning plan for each student
Explanation: Taking time to establish a pupil's learning goals and needs provides you with the information you need to make an effective learning plan. It involves the pupil in the planning process, so the final product is something they have agreed to and engaged with.
A Devise a way to overcome these learning obstacles with the student
B Give the student additional lessons
C Suggest they use another driving instructor as you can no longer help them
D Teach the student at a slower pace
Correct Answer: A Devise a way to overcome these learning obstacles with the student
Explanation: Learning isn't always a continuous process. Sometimes pupils simply need time to consolidate learning before moving on. On other occasions there may be something blocking progress. You should work with the learner to understand what's happening and agree how to move on.
A As any other part of the road
B As any other type of pedestrian crossing
C As one individual crossing
D As two separate crossings
Correct Answer: D As two separate crossings
Explanation: Some zebra crossings are divided by a central island. Each half is a separate crossing.
A Air in the hydraulic system
B Faulty brake pads
C Faulty engine
D Worn brake discs
Correct Answer: A Air in the hydraulic system
Explanation: If air gets into the hydraulic system, the brake pedal will feel spongy. When you press it, the air is compressed, causing the pedal to move further than normal. As a result, braking efficiency is reduced. Have the system checked by a qualified mechanic: brake faults are too important to be ignored.
A The fog will affect the impact of your brakes
B Vehicles may stop suddenly in the fog
C Visibility will be reduced
D You may be dazzled by fog lights from oncoming vehicles
Correct Answer: C Visibility will be reduced
Explanation: In fog, you won't be able to see as far ahead as you can on a clear day. You'll need to reduce your speed so that, if a hazard develops, you have the time and space to take avoiding action. If you can, try to delay your journey until the fog has cleared.
A In the countryside
B On a side street
C On a single carriageway
D On zigzag lines outside a school
Correct Answer: D On zigzag lines outside a school
Explanation: Parking near a pedestrian crossing creates an obstruction that prevents both drivers and pedestrians from having a clear view. Careless parking is selfish and could endanger other road users.
A Continue as normal
B Put your hazard warning lights on
C Slow down and allow it to pass safely
D Speed up and get away from the vehicle
Correct Answer: C Slow down and allow it to pass safely
Explanation: If a vehicle is taking a long time to overtake, you should try to help the situation by slowing down. Your safety and the safety of other road users could be at risk if you maintain speed and prolong the time it takes for the overtaking manoeuvre to be completed.
A Fifth
B First
C Neutral
D Reverse
Correct Answer: B First
Explanation: By leaving the car in gear, the engine will help to prevent the vehicle from rolling. When parking facing uphill, select first gear. This will maximise the resistance from the engine if the parking brake should fail.
A A hazard which may be particularly dangerous for motorcyclists
B A type of bend in the road
C A type of traffic-calming measure used to reduce speed in urban areas
D Angled roads designed to assist in the drainage of water
Correct Answer: D Angled roads designed to assist in the drainage of water
Explanation: Usually, a road is constructed with a camber: the road surface slopes to assist with drainage. Some bends have an 'adverse camber'. This is where the road slopes towards the outside of the bend. When going around a bend that has adverse camber, you need to take extra care. The forces acting on your vehicle could cause it to leave the road more easily than normal.
A 12 months
B 15,000 miles
C 30,000 miles
D Two years
Correct Answer: A 12 months
Explanation: An MOT certificate will normally be valid for one year. The certificate doesn't warrant the condition of the vehicle at a later date, but simply shows that at the time the certificate was issued the vehicle met the MOT requirements. It's the driver's responsibility to ensure that the vehicle is roadworthy whenever it's driven.
A The alternator is faulty
B The battery needs charging
C The car's generator is not charging the battery properly
D The headlights are starting to fail
Correct Answer: C The car's generator is not charging the battery properly
Explanation: The ignition light should go out once the engine has started. If it comes on during normal driving, this would indicate a fault with the charging system. Have it checked.
Correct Answer: C 70 mph
Explanation: Dual carriageways and motorways share the same 70 mph national speed limit for cars and motorcycles. If a car or motorcycle is towing a trailer, then this maximum permitted speed is reduced to 60 mph.
A After a long journey
B After driving at speed
C When they're cold
D When they're new
Correct Answer: C When they're cold
Explanation: Check the tyre pressures when the tyres are cold. Warm or hot tyres may give a misleading reading.
A To clarify how many lessons a student will need
B To determine the level of instruction the ADI should start with
C To figure out how smart the student is
D To figure out whether the student will need additional training
Correct Answer: B To determine the level of instruction the ADI should start with
Explanation: To design an effective programme of learning, it's important to understand what a pupil brings to the process. This will enable you to decide the level at which instruction can begin. It will also encourage the pupil to engage with the learning process if they're not forced to go over material they already know.
A Carry on with your lessons as normal, it's not your duty to motivate an uninterested student
B Communicate with the student to find out what type of learning style would help them
C Show the student what to do when mistakes are made
D Stick to the lesson plans devised at the very beginning
Correct Answer: B Communicate with the student to find out what type of learning style would help them
Explanation: When planning and delivering a lesson, it's important to remember that we all learn in different ways. Continuing to deliver in the same way, when the pupil is clearly not engaging or making progress, may reduce their motivation even further.
A Flash your hazard lights and gesture to the driver behind you
B Maintain your speed
C Move over as soon as safely possible and let the car behind you overtake
D Speed up to increase your distance between you and the vehicle
Correct Answer: C Move over as soon as safely possible and let the car behind you overtake
Explanation: When you're overtaking on a motorway, you'll sometimes find faster vehicles approaching from behind. When it's safe to do so, you should move over and let them pass. Don't try to enforce the legal speed limit.
Correct Answer: C Park
Explanation: When parking a vehicle with automatic transmission, the gear selector should be moved to the 'P' (Park) position. This locks the transmission and prevents the vehicle from moving forwards or backwards. This will stop it from rolling away should the parking brake fail.
A Every day
B Every month
C Every week
D Every year
Correct Answer: A Every day
Explanation: It's recommended that you check all the lights on your vehicle on a daily basis and replace any faulty bulbs. Carrying spare bulbs and fuses in your vehicle will ensure you can replace a bulb as soon as you find it has failed.
A The test will be cancelled and rescheduled
B They can continue, provided they are wearing glasses or contact lenses
C They will fail the test and won't be able to continue
D They will receive a minor fault
Correct Answer: C They will fail the test and won't be able to continue
Explanation: The eyesight test is carried out at the start of the practical driving test. If a candidate can't meet the eyesight requirements, they'll fail the test and it won't continue any further.
A Brake quickly
B Find a safe place to park
C Park on the left as soon as possible
D Shift to a lower gear and engine brake
Correct Answer: A Brake quickly
Explanation: During an emergency-stop exercise, the examiner will check that the road is clear behind before they give the signal to stop. At the signal, the candidate should keep full control of the vehicle while stopping it as quickly and safely as possible.
Correct Answer: C 60 mph
Explanation: The national speed limit for a car or motorcycle on a single carriageway is 60 mph. You don't have to drive at the speed limit. Use your judgement and keep within the speed limit while driving at a speed that suits the road, weather and traffic conditions.
A To get the attention of road users you recognise
B When something causes you to suddenly slow down on the motorway
C When temporarily parked on the side of the road
D When warning other road users that you're about to stop
Correct Answer: B When something causes you to suddenly slow down on the motorway
Explanation: You may use hazard warning lights when you slow suddenly on a motorway or unrestricted dual carriageway, to warn traffic behind of a hazard ahead. Never use hazard warning lights to excuse dangerous or illegal parking.
A Drop back and maintain the correct distance from the vehicle
B Flash your headlights
C Tailgate the vehicle
D Voice your discontent by sounding your horn repeatedly
Correct Answer: A Drop back and maintain the correct distance from the vehicle
Explanation: There are times when other drivers make incorrect or ill-judged decisions. Stay calm and don't retaliate or react aggressively. Always consider the safety of other road users, your passengers and yourself.
A Continue and allow the driver to overtake you
B Don't be intimidated and don't allow the driver to overtake
C Slow right down
D Speed up so the driver can't catch up to you
Correct Answer: A Continue and allow the driver to overtake you
Explanation: Never obstruct drivers who wish to pass. Speeding up or driving unpredictably while someone is overtaking you is dangerous. If someone overtakes and pulls into the gap in front of you, drop back to maintain a two-second gap.
A Go faster in order to get to your destination quicker
B Open your window and take the next exit
C Put the air conditioning on
D Stop on the hard shoulder and have a nap
Correct Answer: B Open your window and take the next exit
Explanation: Don't ignore feelings of drowsiness while driving. You'll need to find somewhere safe to stop and rest until you feel alert enough to continue your journey. On a motorway, you can either stop at a service area or leave the motorway and then find a safe place to stop. Until you reach a safe place to stop, make sure the vehicle is well ventilated. Don't stop on the hard shoulder to rest.
A Continue reversing and let the pedestrian move out of the way
B Slow down and gesture to the pedestrian to hurry up
C Sound your horn to warn the pedestrian
D Stop and let the pedestrian pass
Correct Answer: D Stop and let the pedestrian pass
Explanation: If you're reversing into a side road and see a pedestrian crossing the road behind your vehicle, wait until the pedestrian has passed before continuing. Don't forget that you may not be able to see a small child directly behind your vehicle. Be aware of the possibility of hidden dangers.
A In case pedestrians are crossing
B In case someone is overtaking
C In case the side road isn't clear
D In case traffic is emerging from the side road
Correct Answer: B In case someone is overtaking
Explanation: In queuing traffic, motorcyclists and cyclists often filter past the stationary vehicles. Before you turn right in a traffic queue, check your mirrors for passing vehicles. Motorcyclists and cyclists are smaller than other vehicles and can be difficult to see, so look for them before turning.
A For driving less than 60mph
B For normal driving
C In the event of an emergency
D To overtake vehicles in the middle lane
Correct Answer: B For normal driving
Explanation: On a motorway, you should keep to the left-hand lane whenever possible. Only use the other lanes for overtaking or when directed by signals. Using other lanes when the left-hand lane is empty can frustrate drivers behind you.
A At all times
B Only in the day
C Only in the night
D Only when there are highway maintenance workers present
Correct Answer: A At all times
Explanation: A circular sign with a red border tells you what you mustn't do. If the circle contains a speed limit, you mustn't exceed the limit, whether the sign is temporary or not.
A Continue driving and clear the level crossing
B Reverse and stop behind the barrier
C Stop and call for help
D Stop and leave the vehicle immediately
Correct Answer: A Continue driving and clear the level crossing
Explanation: If the amber warning lights come on as you're approaching the crossing, you must stop unless it's unsafe to do so. Red flashing lights together with an audible signal mean you must stop. If the warning lights and alarm start as you're driving over the crossing, continue and clear the crossing; it would be dangerous to stop at that point.
A That the vehicle has at least third-party insurance
B That the vehicle has fully comprehensive insurance cover
C That you have access to the vehicle log book
D That you're insured to drive it
Correct Answer: D That you're insured to drive it
Explanation: Driving a vehicle without insurance cover is illegal. If you cause injury to anyone or damage their property, it could be very expensive and you could also be subject to criminal prosecution.
A By driving with your windows closed
B By regularly servicing your vehicle
C By turning on the air conditioning
D By using premium petrol or diesel
Correct Answer: B By regularly servicing your vehicle
Explanation: If you don't have your vehicle serviced regularly, the engine will steadily become less efficient. This loss of efficiency will progressively cause an increase in fuel consumption, engine running problems and increased risk of the vehicle breaking down.
A Diesel can cause skin irritation
B Diesel has a pungent smell
C Diesel is corrosive
D Diesel is slippery
Correct Answer: D Diesel is slippery
Explanation: The diesel you use to run a vehicle is a form of oil and, as such, is very slippery when spilt on the road. The usual places to find diesel spillage are near filling stations and on bends or roundabouts. Overfilled fuel tanks and poorly fitting or missing fuel filler caps are often the cause of diesel spillage, so make sure you replace your fuel filler cap securely after refuelling.
A At night
B In fog
C On a dry road
D On water
Correct Answer: D On water
Explanation: In very wet weather, water can build up between the tyre and the road surface. As a result, your vehicle rides on a thin film of water and your tyres won't grip the road. Gravel or shingle surfaces also offer less grip and can cause problems when braking. An anti-lock braking system may be ineffective in these conditions.
A Flash your fog lights to warn oncoming traffic of a foggy area ahead
B If other drivers are still using theirs, leave them on
C Turn off your fog lights
D Use them in place of your headlights
Correct Answer: C Turn off your fog lights
Explanation: Fog lights should only be used when visibility is seriously reduced. They must be switched off when visibility improves, to avoid dazzling other road users.
A It puts too much strain on your vehicle's battery
B Other drivers might think they're brake lights
C Your fog light bulbs are more likely to wear out
D Your indicators may not function
Correct Answer: B Other drivers might think they're brake lights
Explanation: If you don't switch off rear fog lights when the fog has lifted, drivers behind may find it difficult to see your brake lights. This can be a particular problem on wet roads and on motorways. If you leave your rear fog lights on at night, drivers behind are likely to be dazzled and this could put you both at risk.
A When driving at high speeds over long distances
B When driving in urban areas
C When roads are icy
D When roads are wet
Correct Answer: A When driving at high speeds over long distances
Explanation: Check the vehicle handbook: this should give you guidance on the correct tyre pressures for your vehicle. There may be recommendations to increase the tyre pressure when carrying heavy loads or when travelling continuously at higher speeds, such as when using a motorway.
A Slowly in a high gear
B Slowly in a low gear
C Slowly while gently applying the brakes
D Slowly with the hazard warning lights turned on
Correct Answer: A Slowly in a high gear
Explanation: When there's reduced grip (for example, when there's wet mud, snow or ice on the road), drive in a high gear. The engine then drives the wheels with less torque than if you were using a low gear, and this reduces the likelihood of wheelspin.
A Be prepared to slow down and give way
B Continue as it is your right of way
C Sound your horn to get the driver's attention
D Turn on your hazard warning lights
Correct Answer: A Be prepared to slow down and give way
Explanation: Sometimes, large vehicles may need more space than other road users. If a vehicle needs more time and space to turn, be prepared to stop and wait.
A It will cause damage to the brakes
B It will cause damage to the engine
C The car will pick up speed
D The car will slow down
Correct Answer: C The car will pick up speed
Explanation: Driving in neutral or with the clutch down for long periods is known as 'coasting'. If you do this on a steep downhill gradient, there will be no engine braking to help check your speed.
A Certain types of medication may affect your hearing ability
B Some types of medication can increase your reaction speed
C Some types of medication can reduce your reaction speed
D Your insurance company will want to know
Correct Answer: C Some types of medication can reduce your reaction speed
Explanation: Always check the label on any medication you take, as some medicine can make you feel drowsy and slow your reactions. Your doctor or pharmacist will be able to give you advice about possible side-effects of both prescribed and over-the-counter medicines.
A As part of the engine
B As part of the exhaust system
C In the fuel tank
D In the intercooler
Correct Answer: B As part of the exhaust system
Explanation: Strict controls on exhaust emissions require a catalytic converter to be fitted to the exhaust system of all new vehicles. Catalytic converters remove most of the carbon monoxide, oxides of nitrogen and unburned hydrocarbons from the exhaust gases.
A The wind may blow them towards you as you pass
B The wind might cause the rider to drive faster than usual
C The wind might prompt the rider to stop unexpectedly
D The wind might prompt the rider to turn suddenly
Correct Answer: A The wind may blow them towards you as you pass
Explanation: On a windy day, the blustery conditions will affect motorcyclists and they may be blown off course. If you wish to overtake a motorcyclist in these conditions, make allowances for them and give them extra room.
A After four years
B After one year
C After three years
D After two years
Correct Answer: C After three years
Explanation: A new car in Great Britain doesn't require an MOT test certificate until it's three years old. At all times, it's the driver's responsibility to ensure that the vehicle they're driving is roadworthy.
A A lengthier journey
B A less efficient gearbox
C Increased battery wear
D Poor vehicle handling
Correct Answer: D Poor vehicle handling
Explanation: Carrying a heavy load in a vehicle will change its centre of gravity. This will affect the vehicle's handling on bends, compared with when it's lightly loaded. It's your responsibility to make sure that your vehicle isn't overloaded and that any load is secure.
A They indicate an upcoming roundabout
B They indicate the gap that should be left between vehicles
C They warn you to change direction
D To draw attention to your speed
Correct Answer: D To draw attention to your speed
Explanation: Yellow lines are painted across the road on the approach to some roundabouts. The lines are usually found on dual carriageways, where traffic speeds are higher, or at the end of motorway exit slip roads. They provide a visual warning to remind drivers to check their speed.
A Bus route
B Cycle route
C Primary route
D Secondary route
Correct Answer: C Primary route
Explanation: A primary route is a road of national or regional importance and is the major route between larger towns and cities. The direction signs on these routes have green backgrounds. Many maps and road atlases show these routes in green.
A Anytime
B During slow-moving traffic
C In the event of lane closures
D When overtaking traffic in the middle lane
Correct Answer: C In the event of lane closures
Explanation: If you're towing a caravan or trailer, you mustn't use the right-hand lane on a motorway with three or more lanes, except in certain circumstances, such as when there are lane closures.
A When you're driving out of your driveway or garage
B When you're in slow moving traffic
C When you're making a short journey
D When you're performing a manoeuvre that involves reversing, such a parallel parking
Correct Answer: D When you're performing a manoeuvre that involves reversing, such a parallel parking
Explanation: Seat belts should be worn at all times, unless you're carrying out a manoeuvre that involves reversing. The seat belt should be put back on when you've finished the manoeuvre.
A No, you must not remove your seatbelt while the vehicle is in motion
B Only if you're medically exempt
C Yes, you can do so for any manoeuvre that involves reversing
D Yes, you must remove your seatbelt when performing such manoeuvres
Correct Answer: C Yes, you can do so for any manoeuvre that involves reversing
Explanation: Drivers and passengers must normally wear seat belts. However, a driver may remove their seat belt when carrying out an exercise that involves reversing; this also applies to driving instructors while supervising such manoeuvres.
A A first aid certificate
B ADI certificate
C Cover note
D Insurance certificate
Correct Answer: B ADI certificate
Explanation: If an ADI is charging for a driving lesson, they must display their ADI certificate and appropriate L or D plates on the tuition car.
Correct Answer: C Three years
Explanation: If a driver accumulates 12 or more penalty points within a three-year period, they must be disqualified. This will be for a minimum period of six months and may be longer if the driver has previously been disqualified.
A Ask the student how they would prefer you to communicate with them
B Learn basic sign language
C Speak slowly and clearly so the student can lip-read
D Write down lesson plans and present them to the pupil
Correct Answer: A Ask the student how they would prefer you to communicate with them
Explanation: Most people with hearing difficulties will have developed communications strategies that work for them. For example, they may be able to use a simple system of hand signals. However, if you're unable to work out a way of communicating effectively, you should consider referring the pupil to another driving instructor who has the necessary skills.
A Close the car window
B Drive at a slower speed
C Leave the motorway, stop where it is safe and rest
D Park on the hard shoulder and rest, provided it safe to do so
Correct Answer: C Leave the motorway, stop where it is safe and rest
Explanation: If you feel drowsy while driving on a motorway, find a safe and legal place to park as soon as you can. This will mean either leaving the motorway at the next exit or pulling in at the next service area.
A Check the mirrors, signal and overtake
B Don't overtake until the junction has been cleared
C Overtake before the junction
D Overtake on the left, if it is safe to do so
Correct Answer: B Don't overtake until the junction has been cleared
Explanation: Advise a pupil that they should never overtake on the approach to a junction. The driver they're following may decide to turn right at the last moment. Other vehicles may arrive quickly at the junction and turn left into your road without taking effective observation.
A To allow pedestrians to cross safely
B To allow space to overtake or turn in the road
C To indicate a speed limit of 30mph
D To separate traffic travelling in opposite directions in the two lanes
Correct Answer: D To separate traffic travelling in opposite directions in the two lanes
Explanation: Hatch markings are painted at potentially dangerous areas to separate streams of traffic. For example, they can be seen at sharp bends and at junctions to protect traffic turning right.
A Ignore the second line and continue through the amber light
B Stop and reverse back to the first line
C Stop in the bicycle area, before the second line
D Stop wherever you deem it is safe to
Correct Answer: C Stop in the bicycle area, before the second line
Explanation: Some junctions have advanced stop lines with an area for cyclists to position themselves ahead of other traffic. You must stop at the first white line you reach. If you're unable to stop safely at the first line, you must stop at the second line, even though you'll be blocking the area reserved for cyclists.
A Bicycle
B Bus
C Lorry
D Taxi
Correct Answer: A Bicycle
Explanation: This sign prohibits all motor vehicles. Only pedal cycles may pass it. However, a black-and-white plate underneath the sign may give exemptions; for example, 'except buses' or 'except for access'.
A Automatic Number Plate Recognition (ANPR) technology is being used in this area
B Mobile speed cameras operate in this area only
C Speed cameras are not in use
D Traffic enforcement cameras operate in this area
Correct Answer: D Traffic enforcement cameras operate in this area
Explanation: This sign reminds all road users that they're entering an area where cameras will monitor traffic regulations. This could include traffic-light cameras and bus-lane cameras, as well as the more common speed cameras.
A Red route
B Restricted road
C Ring road on a primary route
D Roadworks in progress, take an alternative route
Correct Answer: C Ring road on a primary route
Explanation: Ring roads are designed to keep traffic away from town centres. Unless you need to visit the town centre, you should use the ring road, as this will help to avoid congestion and reduce your journey time.
A It is now safe to overtake
B Overtaking vehicles should move back to the left
C There is a sharp left bend in the road up ahead
D Vehicles must take the next road on the left
Correct Answer: B Overtaking vehicles should move back to the left
Explanation: This curved arrow on the road indicates the direction that traffic should pass solid double white lines that are coming up. These arrows are also used on the approach to hatch markings and low arched bridges. Sometimes the arrow may curve to the right.
A No overtaking
B Oncoming traffic has priority
C One-way traffic only
D Two-way traffic
Correct Answer: B Oncoming traffic has priority
Explanation: The sign means 'Give way to oncoming vehicles', and it will be used where the road narrows; for example, where traffic-calming build-outs reduce the road width. It should not be confused with the blue rectangular sign that gives priority in the other direction.
A Call a friend or relative
B Call the emergency services
C Call your insurance company
D Stop at the scene
Correct Answer: D Stop at the scene
Explanation: If you're involved in a collision that causes damage or injury to any other person, vehicle, animal or property, by law you must stop. Give your name, the vehicle owner's name and address, and the vehicle's registration number to anyone who has reasonable grounds for requiring them.
A 50 metres (164 feet) ahead
B As far as possible
C Just behind the vehicle you're following
D Just in front of the vehicle you're following
Correct Answer: C Just behind the vehicle you're following
Explanation: Following too closely behind another vehicle at night may dazzle the driver. If you drop back, your headlight beam will fall short of the vehicle and so avoid dazzle.
A Give way to any pedestrians on the crossing
B Signal any waiting pedestrians to cross
C Speed up and go past quickly
D Stop under any circumstance
Correct Answer: A Give way to any pedestrians on the crossing
Explanation: At a pelican crossing, there's a phase where the amber light flashes. This will show after the red light and gives pedestrians time to finish crossing safely. For drivers, the flashing amber light means they may drive on if the crossing is completely clear, but they must wait if pedestrians are still on the crossing.
A It will double it
B It will halve it
C Stopping will take ten times longer
D There will be no difference
Correct Answer: A It will double it
Explanation: In heavy rain, the road will be wet and there may be pooling surface water. This will reduce the grip the tyres have on the road and will at least double the distance it takes to stop. Take this increased stopping distance into account while driving. Double the separation distance you'd leave in dry conditions.
Correct Answer: B 3,500 kgs
Explanation: Any more weight than this will take the vehicle into a different category, therefore making it unsuitable for a category B driving test.
A At least at eye level or at the top of the ears
B At the top of the spine
C In the highest position possible
D Just above the head
Correct Answer: A At least at eye level or at the top of the ears
Explanation: An incorrectly adjusted head restraint will offer reduced protection against whiplash injury. When adjusting the head restraint, set it so that it's at least as high as the eyes or top of the ears.
A Park on the hard shoulder, walk down and collect the bag when it is safe to do so
B Stop and retrieve it, but put your hazard warning lights on
C Stop at the next available emergency telephone and inform the authorities
D Stop further down the motorway and walk back to retrieve it
Correct Answer: C Stop at the next available emergency telephone and inform the authorities
Explanation: Drivers shouldn't try to retrieve anything from a motorway. The danger from, and to, passing traffic caused by someone on the carriageway shouldn't be underestimated. The recommended course of action is to go to the next emergency telephone and report the incident to the control centre.
A Discuss the matter with the examiner
B Inform the driving test centre manager
C Make an appeal to the Magistrates' Court
D Write to the DVSA
Correct Answer: C Make an appeal to the Magistrates' Court
Explanation: It must be appreciated that the examiner's decision can't be changed. However, if the candidate believes that the test wasn't conducted properly, they have the right to appeal to the Magistrates' Court in England and Wales or the Sheriff's Court in Scotland.
A It carries out braking for you
B It employs a secondary braking system
C It prevents the wheels from locking up
D It strengthens the brakes and makes them more effective
Correct Answer: C It prevents the wheels from locking up
Explanation: An anti-lock braking system (ABS) prevents the wheels from locking, so you can continue to steer the vehicle during heavy braking. ABS doesn't replace the need to plan well ahead and brake smoothly and progressively.

About the ADI Theory Test

To become a professional driving instructor in the UK you have to pass the Approved Driving Instructor (ADI) Theory Test. But what does the ADI test involve? How do you book your ADI theory test? And how should you prepare to pass your ADI theory test?

The complete ADI test is made up of the theory test (part 1: £81), a practical test (part 2: £111), and an instructional ability test (part 3: £111). You will also need to meet certain requirements to become an instructor, get a trainer, get practice teaching (optional), and register as an instructor. The ADI theory test itself is made up of 2 key component parts as laid out below:

Multiple Choice

This is made up of 100 multiple choice questions broken down into 4 categories. You will have 90 minutes to answer as many of these as you can. To pass, you will need to answer at least 85/100 correctly. You also need to answer at least 20/25 questions correctly across each of the 4 categories.

Hazard Perception

This includes 14 CGI video examples of potential real-life scenarios that could affect you at work. In each clip, there will be at least 1 developing hazard. However, one clip will contain 2 developing hazards. For each of the developing hazards, you can score up to 5 points. You will receive a higher score for spotting a developing hazard quicker. The pass mark for the hazard perception test is 57 out of a possible 75.

What is included in the ADI multiple choice test?

On the day of the test, you will be given instructions on how it works. You will also be given some time to get used to answering questions on the test centre computers. As outlined, the multiple choice test includes 100 questions across 4 categories. To pass you need an overall pass mark off 85% (85/100) and 80% for each category (20/25).

The 4 categories you will be asked questions on are:

Road procedure

For example, this might include questions about stopping distances in wet weather and driving in poor conditions, safety considerations when reversing, and motorway safety.

Traffic signs and signals, car control, mechanical knowledge, and pedestrian responses

For example, this will test sign comprehension, consideration for other road users, and safe vehicle use.

Driving test, disabilities, and legal regulations

For example, this could include questions regarding insurance, understanding reasonable adjustments for people with a disability, and regulations surrounding the vehicle such as parking and seat belts.

Publications and techniques for instruction

For example, this will include questions on how to approach errors of pupils, how to provide reasonable adjustments, and how to teach good practice.

For the multiple choice section of the ADI theory test, it is possible to return to questions. If you are unsure of an answer, simply flag the question and you can return to it later if you still have time.  You have 90 minutes to complete the test. However, if you finish early, then you do not have to use all of this time. You are also allowed to take a 3-minute break before starting the hazard perception test.

ADI hazard perception test

Prior to starting the hazard perception test, you will be shown an instructional video. This will take you through the scoring and how to spot a developing hazard. Simply put, a developing hazard is anything you see that might cause you to take an action. This might be changing your speed or altering your direction of travel. For example, this might be a parked car at the side of the road turning its indicator on.

You can score up to 5 points per hazard. 5 points will be awarded if you spot a developing hazard straight away. 0 points will be awarded if you do not spot a developing hazard during a clip. As such, you should click as soon as you see something that could be a developing hazard. You will not be docked points for clicking if you were wrong. However, if you click in any sort of pattern or continuously, you will be given a score of zero.

Unlike the multiple choice part of the ADI theory test, you cannot review your answers. This means you get one time only per video clip (although you can click more than once per video clip). Remember that there is always at least one developing hazard in each of the 14 clips you are shown. One clip also contains 2 developing hazards, so you should always stay alert for hazards, as you would on the road.

ADI theory test pass mark

To pass the ADI theory test you need to achieve a pass mark for both the multiple choice and hazard perception components. You need to score 85 out of 100 in the multiple choice test. This must include getting at least 20 out of 25 for each of the 4 categories being tested. As such, it is possible to score over 85 and still fail the test. You need 57 out of 75 to pass the hazard perception test.

If you pass both parts of the ADI theory test, you will be given a pass certificate on the day of your test. The certificate is valid for 2 years and is required in order to take the Approved Driving Instructor part 2 test, a practical test.

If you fail either part of the ADI theory test, you will be given a breakdown of your scores. This will show the parts of the test you didn’t score enough on. This can help you when practising for the next test. You cannot book a re-sit until at least 3 working days after sitting your last test.

ADI theory booking

You need to apply to start the ADI qualification process and have this accepted before you can book a test. You will also need to obtain a Disclosure and Barring Service (DBS) check to begin your application. You are eligible to apply if:

  • You are 21 or over
  • You have held a full driving licence for a minimum of 3 years
  • You have not been disqualified from driving in the last 4 years

Your application may also be refused if:

  • You have ever been banned from driving
  • You have 5 penalty points or more
  • You have been convicted of non-motoring offences
  • You have been banned from working with children

If you only have an automatic licence, you are only able to teach people how to drive an automatic car. However, if you have an automatic licence because of a disability, you can take an additional test to allow you to teach drivers of manual cars. You will need to prove you can keep control of the car in an emergency.

ADI Theory Test practice

You will need to practice your knowledge of the following areas:

How to prepare

You are expected to have a higher standard of knowledge for the ADI theory test than the standard learner theory test. Fortunately, this will help you teach your students. The process of learning for your theory test will also be beneficial for you when it comes to preparing your students. Try to keep track of what you find useful when studying for the test and pass this information on. Be sure to practice questions covering each of the 4 categories that will be covered by the multiple choice test.

It is also important to practice using example hazard perception videos. Remember, these will also require a higher level of knowledge than the standard learner hazard perception test. As you need to pass both sections to move on to the next stage, you should be sure to make time to practice hazard perception. As you only get one chance during the test, make sure to pass a few practice tests before booking your test.
