Does the speed at which a vehicle travels influence the driver's reaction distance?
A)No.
B)No, it only affects the stopping distance.
C)Yes, because during the reaction time the vehicle will cover a greater distance.Correct
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.
Reaction distance is the metres travelled by the vehicle during the reaction time. This distance depends on the reaction time and the speed at which one is travelling (the higher the speed, the more metres covered in the same time).
