What primarily causes yaw or fishtailing in a vehicle?

Yaw or fishtailing in a vehicle is primarily caused by a loss of traction in the tires. When a vehicle experiences a loss of traction, the tires can no longer grip the road effectively, which can lead to the rear of the vehicle sliding out. This loss of traction can occur due to various factors, such as wet or icy roads, worn-out tires, or even improper vehicle loading.

Maintaining good tire health and being aware of road conditions can help prevent this dangerous situation. While excessive speed in turns, improper tire pressure, and oversteering can contribute to losing control, the fundamental issue of yaw or fishtailing is rooted in the loss of traction. Understanding how traction works and its critical role in vehicle stability is essential for safe driving practices.
