# Your trailer has begun to snake and swerve. What should you do?

DVSA-style practice question · Vehicle Loading

## The answer options

-   Gently reduce speed**Correct** 
-   Speed up 
-   Sharply brake 
-   Steer immediately 

## Why that is the answer

Trailer snaking is usually caused by high speeds or strong side winds. If your trailer sways, ease off the accelerator and gently reduce your speed so the vehicle and trailer can naturally stabilise. Never brake sharply or steer frantically, as this can cause a jackknife or complete loss of control. Speeding up to try and pull the outfit straight is a dangerous misconception that will only make the instability far worse.

## 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.

## Passed your theory? Get the practical booked

Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
