Skid Marks and Reconstruction of an Accident

Dr. Sampa Dhabal, Dr. Dhrubo Jyoti Sen, d Saumya Chakraborty

Skid marks play a crucial role as evidence in car accident on road. When the brakes of a car are applied suddenly then the wheels of the car are locked. The friction between the tire and road heated the rubber, depositing a thin layer of rubber particles. This black colour layer is skid mark. Anti-lock braking system (ABS) confines braking, locking and skidding by activating and deactivating the brakes several times per second. The study of skid marks left on pavement after an accident occurs that help professionals to reconstruct the accident. The skid mark provides evidence of distance over which braking took place. It means, the distance travelled by the vehicle from the moment of full application of brakes to the moment of vehicle come to a stop. The speed of the car at the moment of accident, also determine from the skid mark. Yaw marks produce when a vehicle travels in a curved path faster than the tires can handle. The different types of tire marks also depend on drag factor and braking efficiency of a vehicle.
