How do you calculate speed of a vehicle by measuring the skid marks after slamming on the brakes?

To calculate the speed of a vehicle based on skid marks, you can use the formula: ( v = \sqrt{2 \cdot a \cdot d} ), where ( v ) is the speed, ( a ) is the deceleration (typically around 0.7g or 9.81 m/s² for dry asphalt), and ( d ) is the length of the skid marks in meters. Measure the length of the skid marks and apply the formula with the appropriate deceleration value to estimate the vehicle's speed at the moment the brakes were applied. This method assumes that the brakes were fully applied and that the vehicle was in a straight line during the skid.


I had an accident the police officer said its no skid marks. does this prove i wasnt speeding?

No. The speed of a vehicle at the time of braking can be estimated by measuring skid marks, but the absence of skid marks doesn't mean the vehicle wasn't moving. Speed can be estimated by a number of other methods.


If a vehicle leaves 150 feet of skid marks. How fast was it traveling?

To estimate the speed of a vehicle that leaves 150 feet of skid marks, you can use a commonly used formula: speed (in miles per hour) is roughly equal to the square root of the skid mark length (in feet) multiplied by 0.7. Using this formula, the speed would be approximately 50.5 mph. However, this is a simplified estimate, and actual conditions such as road surface, tire condition, and braking force can affect the outcome.

What happens during a front wheel skid that is unique compared to a rear wheel skid?

During a front wheel skid, the vehicle loses traction and the front wheels slide sideways. This is unique compared to a rear wheel skid, where the back of the vehicle slides sideways. In a front wheel skid, the driver may lose control of steering, making it harder to regain control of the vehicle.


What do you do when a vehicle starts to skid?

When a vehicle starts to skid, the first step is to remain calm and avoid panicking. Gently steer in the direction you want the front of the vehicle to go, which is often referred to as "steering into the skid." Avoid slamming on the brakes, as this can worsen the skid; instead, gradually ease off the accelerator and allow the vehicle to regain traction. Once control is regained, proceed cautiously.
