Why should your brakes be checked after passing this hazard?

You are now travelling downhill

You will be travelling on a slippery road

You have just crossed a high bridge

Why should your bra… — Your brakes will be wet

The answer options

You are now travelling downhill
Your brakes will be wetCorrect
You will be travelling on a slippery road
You have just crossed a high bridge

Why the other options are wrong

“You are now travelling downhill” is a distractor. It does not meet the standard the question is testing, which your brakes will be wet does. Picking it in the real test costs a mark you cannot get back, and with a pass mark of 43 out of 50 you only have seven to spare.

Why that is the answer

Driving through deep water or a ford gets your brakes wet, which reduces their efficiency and can cause your vehicle to pull to one side. Testing your brakes gently at low speed as soon as you clear the water creates friction to dry them out. You should always do this straight away to ensure you have full braking power before you need it, rather than waiting until you reach a hill or encounter a hazard.

What vehicle handling covers

· Front and rear fog lights and the 100-metre visibility rule
· Descending steep hills in a lower gear and engine braking
· Traffic calming, humps, and driving over tram rails
· Night driving, dipped headlights and dazzle from oncoming traffic

Mistakes learners repeat on this topic

· Leaving rear fog lights on after visibility improves
· Coasting downhill in neutral to save fuel
· Using full beam on a lit motorway or behind another vehicle
· Accelerating between speed humps instead of holding a steady speed

Instructor tip: Any question with fog in it usually turns on the 100-metre rule — check visibility before you check the lights.

How this comes up in the real test

Questions from vehicle handling 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.
