The time interval measured from the exact moment the driver applies pressure to the brake pedal until the vehicle comes to a complete halt. It depends on vehicle speed, weight, tire grip, and the mechanical efficiency of the braking system. This metric is heavily analyzed in accident reconstruction and safety testing to determine if a driver had enough time to avoid a collision.
At highway speeds, the braking time increases significantly if the road is wet or the tires are bald.
