Factors Affecting Stopping Distance Flashcards

All 6 cards in this deck

How does driving faster affect thinking distance and braking distance?

Both increase, so the stopping distance increases.

Why is it safer to drive more slowly in wet weather?

A wet road means less friction between the tyres and the road, so the stopping distance is longer; a slower speed gives a shorter braking distance and reduces the chance of skidding.

Name four factors that increase a driver's reaction time.

Tiredness, distraction, drugs or alcohol, and old age.

True or false? Worn tyres and brakes that need replacing make the stopping distance shorter.

False. Worn tyres and poor brakes increase the braking distance, so the stopping distance is longer.

How does a greater vehicle mass affect stopping distance?

It increases the braking distance, so the stopping distance is longer.

True or false? Alcohol only affects a driver's braking distance, not the thinking distance.

False. Alcohol increases reaction time, which increases the thinking distance and so the stopping distance.
