View explanation

Reaction distance is defined as the distance the vehicle travels during the reaction time, and therefore the distance that elapses from the moment a driver perceives an obstacle on the road until he/she actually presses the brake pedal.

Whether this is greater or lesser will depend on the speed at which the vehicle is traveling and the driver's psycho-physical state.
