Observation, Speed & SpaceStandalone practice
A ball rolls into the street ahead of you. You recognize the danger, and then you move your foot from the gas pedal to the brake. During that foot movement, the car keeps its speed. According to the Virginia Driver's Manual, which part of your total stopping distance is this?
Correct answer: Reaction distance
Why
The manual names three factors of stopping distance: perception time, reaction distance and braking distance. Weather, visibility, and your mental and physical condition affect all three, so fatigue or a distraction adds distance before the brakes even start to work. Braking distance also grows with speed, with worn brakes or tires, and on poor pavement; wet pavement can double it.
