The reaction distance is defined as:
A)The distance travelled from when braking begins until the vehicle comes to a stop.
B)The distance that must be left between two vehicles when travelling one behind the other.
C)The distance travelled from when a hazard is seen until the vehicle's controls are operated.Correct
The reaction distance is the number of metres travelled by the vehicle during the reaction time. This distance depends on the reaction time and the speed at which the vehicle is travelling (the higher the speed, the more metres covered in the same time).
The reaction time is the time that elapses from when the driver sees an obstacle until they react. This time varies depending on the driver's psychophysical state, never due to speed or road conditions. Although it may seem that the reaction to an obstacle or unexpected situation must be instantaneous, the average reaction time of a driver is approximately 0.75 seconds.
