19 Reaction distance

The reaction distance is the distance traveled by the vehicle from the time when the danger is detected until the brakes are applied.

The reaction time is about 1 second. In case of readiness for breaking, the reaction time is substantially shorter.

Rule of thumb

Reaction distance = 3 x	Speed in km/h
	10

Example: Reaction distance at a speed of 80 km/h.

Calculation: 3 x 80 : 10 = 24 m

Example 2: Reaction distance at a speed of 50 km/h.

Calculation: 3 x 50 : 10 = 15 m
