Factors Affecting Braking Distance Flashcards

All 4 cards in this deck

Why does an icy or wet road increase braking distance?

There is less friction (grip) between the tyres and the road, so the braking force is smaller.

Why do worn brakes or worn tyres increase braking distance?

They produce less friction, so the braking force is smaller and the car travels further before stopping.

True or false? Tiredness increases the braking distance of a car.

False. Tiredness increases reaction time, which increases thinking distance, not braking distance.

True or false? In wet or icy conditions drivers should leave a bigger gap to the vehicle in front.

True. Braking distance is greater in adverse conditions, so a longer stopping distance is needed.
