Observation Speed SpaceStandalone practice
With the same reaction time, road grip and vehicle condition, why does a higher starting speed increase the total distance needed to stop?
Correct answer: Both the reaction and the braking distance get longer
Why
During an unchanged reaction interval, a faster vehicle travels farther before the brakes are applied. It then has more speed to lose and needs more braking distance under the stated equal conditions. Total stopping distance includes both parts. Actual results also depend on alertness, tires, brakes, road grip and slope; no single distance fits every situation.
