Observation, Speed & SpaceStandalone practice
A deer runs onto the road ahead of you, and you brake to a stop. Which two distances make up your total stopping distance?
Correct answer: The distance you travel before you brake, plus the distance you travel while braking
Why
Reaction distance is how far you travel after you see a danger and before your foot presses the brake; the guide's chart uses a reaction time of 1.5 seconds. Braking distance is how far you travel after the brakes are applied. Both grow as your speed rises, and you need even more room when you are very tired or your brakes are in poor condition.
