Braking Distance Formula The following table is taken from a Virginia Division of Motor Vehicles Manual and it shows the Reaction Distance, the Braking Distance, and the Total Stopping Distance at various speeds. The Reaction Distance is the distance that your car travels from the time that the driver sees the need to do so until his foot hits the brake. The braking distance is the distance that the car travels after the brakes are applied until it comes to a stop. The Total Stopping Distance is the sum of the Reaction Distance and the Braking Distance. from the Learner's Manual of the Virginia DMV Here are the formulas to compute those distances: Note that both the braking distance and the total stopping distance formulas are quadratic, and therefore their graphs are parabolas. 2.
