What does fishtailing refer to in vehicle operation?

Fishtailing refers to the excessive side-to-side movement of a vehicle, particularly when towing equipment. This phenomenon typically occurs when the rear of the vehicle swings out to one side, causing a loss of stability. It is often seen when there is improper weight distribution or when road conditions are slippery. This can lead to a dangerous situation if not corrected promptly, as it disrupts the balance and control of the vehicle.

In the context of towing, fishtailing can happen if the trailer or towed equipment isn't properly balanced or if the connection between the towing vehicle and the trailer fails to manage this movement effectively. Understanding this concept is essential for safe vehicle operation, especially when towing, to avoid accidents due to loss of control.
