The effects of car accidents on roads are identified by marks that result from the dynamic movement of cars involved in accidents. These marks include scuff marks, skid marks, prints, gap skids, and yaw marks. Skid marks, which are among the most common tire marks, are made by tires that slide without rotating on the road. The sliding may be caused by collision damage, braking, or other reasons. The most common cause of skid marks is braking.
Scuffs are made by yawing or rotating vehicles, flat tires, or accelerating vehicles. Locked wheels leave scrub marks due to damage, prints result from rolling tires, and yaw marks are made by tires that rotate and slide sideways parallel to a wheel’s axle.
All these tire marks are crucial in accident investigations because a vehicle’s specific action produces each mark during the accident. They help investigators know about a motorist’s attempts or actions before and after collisions. Through these marks, investigators are able to determine areas-of-impact or points-of impact, which are crucial parts of traffic accident investigations. Proper interpretation of these marks also help investigators determine which speed calculation formulas they will use. Tire marks are short-lived types of evidence that should be collected as soon as possible for preservation.
