A skid mark is the visible mark left by any solid which moves against another, and is an important aspect of trace evidence analysis in forensic science and forensic engineering. Skid marks caused by tires on roads occur when a vehicle wheel stops rolling and slides or spins on the surface of the road.
Witnesses are interviewed during collision reconstruction, and physical evidence such as tire marks are examined. The length of a skid mark can often allow calculation of the original speed of a vehicle for example. Vehicle speeds are frequently underestimated by a driver, so an independent estimate of speed is often essential in collisions.
Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, [Note 1] and negligibly by the tires' rolling resistance and vehicle's air drag.
Slip ratio is a means of calculating and expressing the slipping behavior of the wheel of an automobile.It is of fundamental importance in the field of vehicle dynamics, as it allows to understand the relationship between the deformation of the tire and the longitudinal forces (i.e. the forces responsible for forward acceleration and braking) acting upon it.
Forensic tire tread evidence records and analyzes impressions of vehicle tire treads for use in legal proceedings to help prove the identities of persons at a crime scene. ...
Skid mark – mark a tire makes when a vehicle wheel stops rolling and slides or spins on the surface of the road. Skid marks are important for finding the maximum and minimum vehicle speed prior to the impact or incident. Trace evidence – evidence that occurs when different objects contact one another. Such materials are often transferred by ...
A surface friction tester, used to measure road slipperiness. Road slipperiness is a condition of low skid resistance due to insufficient road friction. It is a result of snow, ice, water, loose material and the texture of the road surface on the traction produced by the wheels of a vehicle.
In other words, This article should be called "Tire Marks", and then be divided skid marks, acceleration marks, and yaw marks. This is the naming convention used by accident reconstructions, and since that is the context in which this article seems to appear, it should probably be consistent with that.
