Speed, distance & stopping distance

On the A35 you read on an instruction card: 'At 50 km/h the stopping distance is exactly equal to the braking distance: 12.50 m.'

True
False

Correct answer

False

Explanation

False — trap: forgetting the reaction distance. Stopping distance at 50 km/h = 13.75 (reaction distance) + 12.50 (braking distance) = 26.25 m, not 12.50 m (Book p.125-126).
