Correct Answer: C
Explanation: • 2 seconds: No, this would be the correct distance in good weather conditions.
• 3 seconds: No, rule 126 of the Highway Code advises a 2 second gap which should be doubled in poor weather conditions.
• 5 seconds: No, rule 126 of the Highway Code advises a 2 second gap which should be doubled in poor weather conditions to 4 seconds - which would be the minimum... 5 seconds is more than the minimum.
• 4 seconds: Yes, rule 126 of the Highway Code advises a 2 second gap which should be doubled in poor weather conditions.

3. Bob's vehicle is fitted with a range change gearbox. Which range would be best for Bob to use to move away when fully laden?
Mark one answer
B
C
D
Correct Answer: C
Explanation: • High range: No, moving away fully laden will mean that the vehicle will generally require a lower gear.
• Intermediate gears: No, when fully laden, a vehicle will probably require a lower gear to move away from a standstill.
• Split gears: No.
• Low range: Yes, this provides for maximum torque and minimises engine load to get things moving.

Correct Answer: A
Explanation: • PTO: No, a 'PTO' (Power Take Off) allows an ancillary piece of equipment to be powered from the vehicle - it will not affect the driveability of that vehicle.
• Hill assist: No, whilst this may give some improvement under these conditions it is not the best answer here.
• Exhaust brake: The exhaust brake will have no effect on the vehicle traction.
• Diff lock: Yes, locking the wheels of an axle will help reduce wheel spin where one wheel has some grip and the opposite wheel is spinning.

Explanation: It is important to avoid having a bent back when lifting and to try to use the stronger muscles in the legs to do the hard work. You should also avoid lifting with your back twisted (as in image D) and try to keep the load close to your body.
• Image A: No - lifting with a bent back
• Image B: No - lifting with the load too far away from the body
• Image D: No - lifting with a twisted back
• Image C: Yes - lifting with the box held close to the body with a straight back
