How do you measure a vehicular accident?

This method involves using a tape measure or measuring wheel to document the crash scene; however, electronic distance meters or laser instruments can also be used. Accurate, quality and comprehensive traffic accident reports are crucial for entering data into data banks and for performing spatial analyses.

Does size matter in a car accident?

Both size and weight affect the forces people inside a vehicle experience during a crash. The magnitude of those forces is directly related to the risk of injury.

What do skid marks indicate?

Skid marks indicate hard braking by the motorcyclist immediately before the impact. With a motorcycle, skid marks can indicate hard braking by the front tire, rear tire, or both tires. Skid marks can indicate that a rider tried to avoid the collision by forcefully applying the brakes.

By measuring the masses of the cars and the distance that they slid together, and accounting for drag forces, investigators can find total momentum. If one car was stopped, it is easy to calculate how quickly the other car was traveling.
