Q1. Before loading a vehicle, why should the driver check the load's weight against the vehicle's plated gross weight?
  • A.  To calculate the fuel needed for the journey
  • B.  To avoid exceeding the legal maximum and risking prosecution
  • C.  To decide which motorway lane to use
  • D.  To work out the correct tyre pressure only
Show answer & explanation
✓ Answer: B. To avoid exceeding the legal maximum and risking prosecution
Exceeding the plated gross weight is an offence that can result in prosecution, fines and prohibition from continuing the journey. It also affects braking performance and stability, making it a safety issue as well as a legal one. Tyre pressure and lane choice are not the primary reason for the check.
Q2. How many times per week may a driver extend the daily driving limit to 10 hours?
  • A.  Three times
  • B.  Once
  • C.  Twice
  • D.  As often as needed if rest is taken
Show answer & explanation
✓ Answer: C. Twice
The 9-hour daily driving limit can be extended to a maximum of 10 hours, but this is only permitted on two occasions in any given week. Using it more often would breach the rules even if rest periods are otherwise correct.
Q3. What is the minimum legal tread depth for tyres on a goods vehicle exceeding 3.5 tonnes in the UK, across the central three-quarters of the tread and around the entire circumference?
  • A.  1 mm
  • B.  1.6 mm
  • C.  2 mm
  • D.  3 mm
Show answer & explanation
✓ Answer: A. 1 mm
For goods vehicles over 3.5 tonnes, the legal minimum tread depth is 1 mm across the central three-quarters of the width and the entire circumference, which is less than the 1.6 mm required for cars and light vans.
