Physical Evidences

Furls are not a recognized characteristic of tire treads. Common tire tread features include sipes (small slits for better grip), grooves (channels for water dispersion), and ribs (raised portions for stability). These features are essential for analyzing tire impressions in forensic investigations.

Yaw marks are curved tire marks caused when a vehicle slides sideways while still moving forward. These marks indicate a loss of control and are often used in accident reconstruction to determine the vehicle’s speed and path.

Skid marks are the result of braking and tire-road friction. Analyzing the length and pattern of skid marks helps in estimating the vehicle’s speed during braking and contributes to accident reconstruction.

The density gradient method is a precise technique for comparing glass fragments. Bromoform and Bromobenzene create a gradient due to their varying densities, allowing small differences in glass fragment densities to be detected. This method is widely used in forensic science.
