Vehicle Loading — free theory test practice
Vehicle loading is a small band with a high pass rate if you learn three ideas: the driver is responsible for the load, weight should be low and evenly spread, and a badly loaded trailer will snake.
Questions also cover who is responsible for children wearing restraints and how a roof box changes handling and fuel use.
Once you're passing this topic comfortably, try a full mock test under real timed conditions, brush up on UK road signs, or browse the full question bank. Ready to drive? See our intensive driving courses.
Vehicle Loading
Question 1 of 21
A trailer braking system must have a safety device fitted. What is this device?
What the DVSA tests on vehicle loading
- Driver responsibility for load security and legal weight limits
- Loading a trailer or caravan and the effect on stability
- Stabilisers, breakaway cables and towing mirrors
- Roof racks, roof boxes and the effect on fuel consumption
- Child restraints and who is responsible for them
Common mistakes in this topic
- Loading heavy items high or towards the rear of a trailer
- Assuming a stabiliser corrects a badly distributed load
- Believing the passenger is responsible for a child's seat belt
- Forgetting that a roof load raises the centre of gravity in crosswinds
Instructor tip: Any snaking-trailer question resolves to slowing down gently — never brake hard or accelerate out of it.
