Practise UK stopping distance questions, lock the key figures in properly, and understand what changes them in real conditions. This is one of the easiest theory topics to turn into reliable marks once the numbers stop feeling like guesswork.
Stopping distances are one of the cleanest scoring areas in the theory test. The figures are fixed, the pattern is learnable, and once you understand the link between speed, thinking distance and braking distance, these questions should become marks you expect to get rather than marks you hope for.

Instructor insight
What I see learners get wrong in lessons
Most learners can memorise a few stopping distance numbers. The harder part is understanding why those numbers get much worse in real driving.
Rain, ice, worn tyres, tiredness and distractions all increase the distance needed to stop safely.
The two-second rule is useful, but it must be increased when the road surface or visibility is poor.
Leaving space behind the vehicle in front gives you time to think before you have to brake.

Get these figures solid first. Once you can recall them quickly, the rest of the topic becomes much easier because you are not trying to reason from scratch every time.
What changes stopping distance?
Total stopping distance is made up of thinking distance and braking distance. Speed, tiredness, alcohol, distractions, wet roads, icy roads, poor tyres and worn brakes can all push that distance out. So the theory test is not only checking whether you know the figures — it is checking whether you understand what can make safe space disappear faster than expected.
How to improve your stopping distances score
Memorise the six normal-road figures until they come back without hesitation.
Make sure you can explain the difference between thinking distance and braking distance.
Use short practice sets until the topic feels automatic rather than forced.
Move into full mocks to prove the numbers still hold up under time pressure.

Use focused stopping distances practice first, then move into a full mock to check that the figures still come back instantly when you are under pressure and switching between different topics.
