The answer options
- Anti-lock brakes on the towing vehicle
- A stabiliser on the tow barCorrect
- Power steering on the towing vehicle
- A jockey wheel on the tow bar
Why that is the answer
Fitting a stabiliser to your tow bar helps counteract snaking and pitching, which can happen in strong winds or when large vehicles pass by. This keeps the caravan aligned with your car and significantly improves overall handling. While a jockey wheel is useful for maneuvering an uncoupled caravan, it does nothing while driving. Anti-lock brakes and power steering assist the towing vehicle itself, but they will not stabilise the caravan.
How this comes up in the real test
Questions from vehicle loading appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.
The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
