What do sharp angles in skid marks indicate?

Sharp angles in skid marks typically indicate sudden changes in the direction of a vehicle’s travel. When a vehicle skids, the resulting marks on the road surface reflect the path taken by the tires during that loss of traction. If the marks change direction sharply, it suggests that the driver made a significant steering input or maneuver, altering the vehicle's trajectory immediately before or during the skid.

This behavior illustrates how a vehicle reacts when the driver attempts to steer while braking, indicating adjustments made in response to road conditions or obstacles. While there may be some elements of truth in the other options, such as braking before impact (which could produce skid marks), sharp angles specifically point to a rapid directional change rather than simply the act of braking or tire performance. Understanding the nuances of skid marks can significantly aid in reconstructing the events leading up to a traffic crash, making it crucial for investigators to analyze such details accurately.
