Stopping distance (feet) = speed (mph) * reaction distance (feet) + braking distance (feet)
Reaction time is the time it takes for you to perceive a hazard and apply the brakes. At 55 mph, the average reaction distance is 120 feet. Braking distance is the distance your vehicle will travel after you apply the brakes. At 55 mph, the average braking distance is 111 feet.
Therefore, the total stopping distance at 55 mph is 231 feet. This distance can vary depending on a number of factors, including road conditions, weather conditions, and the condition of your vehicle. It is important to be aware of the stopping distance of your vehicle so that you can drive safely and avoid accidents.
