B Move the people who are injured clear of their vehicles
C Switch on your own hazard warning lights
D Try and get people who are injured to drink something
Correct Answer: C Switch on your own hazard warning lights

Don't move casualties trapped in vehicles unless they're in danger.

B Make a list of witnesses
C Sweep up any loose debris
D Take the numbers of the vehicles involved
Correct Answer: A Check the casualty's airway

A Whether they can breathe
B Whether they have any bruising
C Whether they have broken bones
D Whether they're bleeding
Correct Answer: A Whether they can breathe
Explanation: At the scene of an incident, first make sure there's no danger of further collisions or fire before dealing with any casualties. The priority when dealing with an unconscious person is to make sure they can breathe. This may involve clearing their airway if they're having difficulty or there's an obvious obstruction. Don't remove a motorcyclist's helmet unless it's essential, as you could cause them serious injury.
A Check that they're breathing
B Look for any witnesses
C Take the numbers of the vehicles involved

A Check that the casualty can breathe
B Get the casualty a warm drink
C Take details of any witnesses
D Take the numbers of the vehicles involved

If you feel you aren't capable of carrying out first aid, consider taking some training. It could save a life.

B Apply pressure over the wound and raise the arm
C Dab the wound

C Stand at the edge of the carriageway to warn others

A Close your sunroof
B Remove your sunglasses
C Switch off your radio
D Switch on your windscreen wipers

A Use dipped headlights
B Use front spotlights
C Use parking lights
D Use rear fog lights
Correct Answer: A Use dipped headlights
Explanation: Before entering a tunnel, you should switch on your dipped headlights; these help you to see and be seen. In many tunnels, using headlights is a legal requirement. You should also remove your sunglasses before you drive into a tunnel.
A Change to a lower gear
B Check your tyre pressures
C Put on your sunglasses
D Tune your radio to a local channel
Correct Answer: D Tune your radio to a local channel
Explanation: On the approach to many tunnels, a board will indicate a local channel or radio frequency that you should tune into. This should give a warning of any incident or congestion in the tunnel ahead. Severe loss of life has occurred in tunnel fires. Getting advance warning of any problems ahead will help you to take appropriate action in good time.
A Ignore any message signs as they're never up to date
B Keep a safe distance from the vehicle in front
C Put your headlights on full beam
D Stop very close to the vehicle in front to save space
Correct Answer: B Keep a safe distance from the vehicle in front
Explanation: It's important to keep a safe distance from the vehicle in front at all times. This still applies in congested tunnels, even if you're moving very slowly or have stopped. If the vehicle in front breaks down, you may need room to manoeuvre past it.
A Rely on CCTV cameras seeing you
B Remain in your vehicle
C Switch on hazard warning lights
D Wait for the police to find you
Correct Answer: C Switch on hazard warning lights
Explanation: If your vehicle breaks down in a tunnel, it could present a danger to other traffic. First, switch on your hazard warning lights. If there are passengers in your vehicle, take them to the nearest exit point. You should then call for help from an emergency telephone. Don't rely on being found by the police or being seen by a CCTV camera. The longer a vehicle stays in an exposed position, the more danger it poses to other traffic.
A Drive it out of the tunnel if you can do so
B Leave it where it is, with the engine running
C Park it away from the carriageway
D Stop, then walk to an emergency telephone point
Correct Answer: A Drive it out of the tunnel if you can do so

A Closely follow the tail lights of other vehicles
B Follow the instructions given by variable message signs
C Stay close to the vehicle in front to reduce congestion
D Switch off your dipped headlights to reduce dazzle
Correct Answer: B Follow the instructions given by variable message signs

A Douse the burns with cold water
B Remove anything sticking to the burns
C Remove smouldering clothing
D Try to put out the fire
Correct Answer: A Douse the burns with cold water

A Raise their legs to help with circulation
B Remove any obstruction from their mouth
C Tilt their head as far forward as possible
D Try to give them something to drink
Correct Answer: B Remove any obstruction from their mouth

B Stay with your vehicle; you'll be seen by the CCTV cameras
C Stop at the side of the road and switch off the engine
D Wait for the police; tunnels are regularly patrolled
Correct Answer: C Stop at the side of the road and switch off the engine
