Does the speed at which a vehicle is travelling affect the driver's reaction distance?
- ANo.No.
- BSí porque durante el tiempo de reacción el vehículo recorrerá más distancia.Yes, because during the reaction time the vehicle will travel a greater distance.

Correct answer
- BSí porque durante el tiempo de reacción el vehículo recorrerá más distancia.Yes, because during the reaction time the vehicle will travel a greater distance.
Reaction time is the time from when the driver sees an obstacle until they react. It varies with the driver's physical and mental state, never with speed or the condition of the road. Although it may seem that the reaction to an obstacle or unexpected situation should be instant, a driver's average reaction time is about 0.75 seconds. The reaction distance is the number of metres the vehicle travels during the reaction time. This distance depends on the reaction time and on the speed (the higher the speed, the more metres travelled in the same time).
