Tailswing

Tailswing is when a vehicle's tail moves in an opposite radial direction from the vehicle's nose.

While nearly all roadway vehicles exhibit at least some tailswing, it is usually exacerbated by vehicles with a large rear overhang, where much of the vehicle extends past the rear axle. This phenomenon is of great significance to shuttle drivers, since improperly managed tailswing can destroy nearby cars or injure pedestrians behind the bus.

Tailswing is similar to Front Overhang, but is not considered beneficial.
