• Working Tuesday, Wednesday, Thursday and Friday: No, because a driver may only extend his driving period to 10 hours twice in any fixed week and that fixed week ends at midnight Sunday.
• Working Thursday, Friday. Saturday and Sunday: No, because a driver may only extend his driving period to 10 hours twice in any fixed week and that fixed week ends at midnight Sunday.
• Working Saturday, Sunday, Monday and Tuesday: Yes, because the Saturday and Sunday driving periods fall into "week 1" whilst those on Monday and Tuesday fall into the "second week".

• TIR: No, TIR is requirement for carrying goods outside of the EU block. It generally refers to the good, although some vehicles will be tested to TIR standards and it does not refer to the driver.
• ADI: No, an ADI is an Approved Driving Instructor and that qualification would have no relevance here.
• ADR: Yes, this is the qualification needed by drivers using vehicle for the carriage of dangerous goods.

B 26 tonnes
C 32 tonnes
D 38 tonnes

• 32 tonnes: No, this would be the maximum weight of a 4-axle rigid vehicle.
• 38 tonnes: No, this would be the maximum weight of a 2-axle articulated tractor unit pulling a 2-axle semi-trailer.

A A - Front-mounted hazard plate
B B -Side-mounted hazard plate
C C - Wheel-nut indicators
D D - Rear-mounted fire extinguisher
Correct Answer: D D - Rear-mounted fire extinguisher

B Three - one on each side and one on the rear
C Two - one on each side of the tank
D Two - one on the rear and one on the off-side of the vehicle
Correct Answer: B Three - one on each side and one on the rear
Explanation: • Four - one on the front, one on the rear and one on each side of the vehicle: No, whilst there are 4 placards in this case, the one on the front is plain orange and does not carry the information that these others do. This is therefore not the best answer here.
• Two - one on each side of the tank: No, this is not the complete answer.
• Two - one on the rear and one on the off-side of the vehicle: No, this is not the complete answer.
• Three - one on each side and one on the rear: Correct.
Correct Answer: A A
Explanation: • B: The red diamond is the "hazard warning diamond" in this case informing that it is a flammable liquid.
• C: Labeline is the manufacturer of the plate.
• D: The telephone number on the bottom of the plaque is the "emergency advice number" often that of the manufacturer of the substance and generally used by the emergency services if they need specialised advice regarding the risks posed by the material or the action to be taken if it is spilled.
• E: The box containing the figures "1203" refer to the UN Substance Identification Number (in this case the substance is petrol).
• A: Yes. The characters "3YE" provide the emergency action code.

A It must be emptied of all petrol
B It must be purged of its previous load
C It must be washed out with water jetting equipment
D Nothing because it would be empty after her last delivery last week
Correct Answer: B It must be purged of its previous load
Explanation: • It must be emptied of all petrol: No, this is not the best answer here.
• It must be washed out with water jetting equipment: No, water jetting may not be the best way of achieving a clean tank for these purposes.
• Nothing because it would be empty after her last delivery last week: No, this type of vehicle is not deemed "empty" until it has been "purged" of all traces of the previous load.
• It must be purged of its previous load: Yes, the proper term to use is "purged" - this ensures there is no element of the previous load remaining to contaminate any subsequent load. With ADR vehicles, they are not deemed "empty" until they have been "purged".
A They are purely decorative
B They cover any noise coming from squeaking wheel nuts
C They help keep the wheel nuts clean and free from rust
D They indicate any movement of the wheel nuts
Correct Answer: D They indicate any movement of the wheel nuts
Explanation: • They are purely decorative: No, they do serve a practical purpose.
• They help keep the wheel nuts clean and free from rust: No, although they may, in practice do this, but this is not their real purpose.
• They cover any noise coming from squeaking wheel nuts: No, they would not cover any noises and. should such a noise be coming from the wheel nut area, it may suggest a defect.
• They indicate any movement of the wheel nuts: Correct - they are fitted in pairs with the arrow pointing toward each other, if the nut comes loose, it immediately becomes more noticeable to the driver.
