2. REACTION DISTANCE

Reaction Distance is how far a vehicle travels during the Reaction Time. Reaction Time is how long it takes to respond to a situation by moving your foot from the accelerator pedal to the brake pedal. The average reaction time is three-quarters of a second.
3. BRAKING DISTANCE

Braking distance is how far the vehicle travels during Braking Time. Braking Time is how long it takes a vehicle to stop after the brakes are applied.

 

In short, Total stopping distance is the sum of perception distance, reaction distance and the braking distance. The chart below illustrates the minimum stopping distance for various speeds. The stopping distances are averages for stopping on smooth, dry pavement.
