Why should you teach your pupils to test their brakes after driving through a ford?

Why this is the answer

At a ford, the road passes through a stream at a place where the water is normally shallow. When your pupil has gone through the water, they should test their brakes and if necessary dry them out. To do this, they must first check that they will not cause danger to traffic behind. Then apply a light brake pressure while moving slowly. It's important that they make sure their brakes are working properly before resuming normal driving.

Why the other answers don't fit

A
To check their brake lights are working — Brake lights are checked before the journey and are not what water affects.
C
To see if the car is aquaplaning — Aquaplaning happens at speed on standing water, not at a ford.
D
To remove the water from your tyres — The water on the tyres matters less than the water in the brakes.

Where this question comes from

The question, its options and the explanation are reproduced word for word from the DVSA revision question bank under licence. The licence requires them to appear unaltered, so we cannot reword them and neither can anyone else — that is why you will meet the same wording on other sites. Everything else on this page is written by Theory Hub: the explanation of why each wrong answer is wrong, the topic guide and the revision notes.
