      Braking on most surfaces slows a vehicle at 15 feet per second, per second of braking.


      At 55 MPH around 225 feet for example.


      You do the math.

        One formula for calculating the speed in miles per hours of a vehicle from its skid marks is
        speed = 2 x √(L x 5), where L is thelength of the skid marks in feet.
