The reaction distance is:

Correct answer

The distance travelled by the vehicle during the reaction time.

The reaction distance is defined as the distance travelled by the vehicle during the reaction time. It is therefore the distance covered from the moment a driver perceives an obstacle on the road until they actually press the brake pedal. Whether it is greater or smaller depends on the speed at which the vehicle is travelling and the driver's psychophysical condition.
