## Types of Skid Marks **Anti-lock Braking System (ABS) Scuff Marks:** - Patterns left by a vehicle with anti-lock brakes when braking hard. - Caused by a wheel rotating and slipping on the road surface. - Often appear faint and intermittent, disappearing within 15-20 minutes. **Intermittent Skid Marks:** - A series of heavy skid marks with long gaps (more than 15 feet). - Caused by a driver rapidly applying and releasing the brakes. - Uniform length and spacing, less than 3-4 feet apart. **Skip Skid Marks:** - Series of skid marks with irregular intervals, caused by a sudden load shift from braking hard. - Typically appear when vehicles bounce, often from trailer vehicles. - Can also be caused by vehicles skidding on a bumpy road. **Offset Skid Marks:** - Skid marks indicating a sudden tire direction change due to collision forces. - Direct result of vehicle movement during a collision. - Pinchpoint evidence of the exact location of impact. **Squeegee Mark:** - Strip of dry pavement remaining after a vehicle skids on a wet road. - Caused by a locked tire removing water from the skid path. - Disappear quickly and are temporary. **Furrow Mark:** - Trench dug by locked tires on soft surfaces like gravel, sand, or dirt. - Shallow at the beginning of the skid and deepens as the vehicle moves. **Scuff or Yaw Mark:** - Occurs when a vehicle loses traction due to excessive speed or oversteering. - Tires continue rotating but slide sideways, creating marks that remain on the road. - Show evidence of the driver losing control of the vehicle. **Acceleration Scuff Marks:** - Caused by rapid acceleration from a stop. - Produce gradually fading dark tire marks. **Tire Print:** - Mark left by a tire rolling over soft materials like sand, dirt, or liquids. - Leaves an identifiable pattern matching the tire tread.
