WebHow to calculate braking distances. The braking distance, also called the stopping distance, is the distance a vehicle covers from the time of the full application of its brakes until it has stopped moving. This is often given as a 100-0kph distance, e.g. 56.2m, and is measured on dry pavement. WebOct 15, 2014 · Stopping sight distance is the distance traveled from the instant the driver sees and recognizes a hazard to the instant the brakes are applied (brake reaction time) plus the distance actually needed to stop the vehicle (braking distance).
