Although the speed of a vehicle can be determined by the length
of it's skid marks, the grade of the road and the condition of the tires
must also be considered. Also, if the vehicle was still moving at the time
of the impact, skid/speed formulas will only yield the minimum "original"
speed.
The form above is designed to estimate the speed of the vehicle
based on general surface conditions. It should not be used as a substitute
for a proper accident reconstruction investigation.
Formula:Speed = √(30 x CD x Length) |
