4.5.6.3.3 Factors affecting braking distance

Content

THE braking distance of a vehicle can be affected by adverse road and weather conditions and poor condition of the vehicle.

Adverse road conditions include wet or icy conditions. Poor condition of the vehicle is limited to the vehicleâ€™s brakes or tyres.

Students should be able to:

• explain the factors which affect the distance required for road transport vehicles to come to rest in emergencies, and the implications for safety
• estimate how the distance required for road vehicles to stop in an emergency varies over a range of typical speeds.
