Explanation
Reaction distance is how far your vehicle will continue to travel after you see a hazard until you physically hit the brakes. This distance varies depending on the weather conditions. On average, a driver has a reaction time of ¾ second to 1 second. At 50 MPH, this accounts for 55 feet traveled.
