When an understeering vehicle is taken to the grip limit of the tyres, where it is no longer possible to increase lateral acceleration, the vehicle will follow a path with a radius larger than intended. Although the vehicle cannot increase lateral acceleration, it is dynamically stable.

When an oversteering vehicle is taken to the grip limit of the tyres, it becomes dynamically unstable with a tendency to [[Spinout (driving)|spin]]. Although the vehicle is unstable in open-loop control, a skilled driver can maintain control past the point of instability with [[Opposite lock|countersteering]] and/or correct use of the throttle or even brakes; this is done purposely in the sport of [[Drifting (motorsport)|drifting]].

If a rear-wheel-drive vehicle has enough power to spin the rear wheels, it can initiate oversteer at any time by sending enough engine power to the wheels that they start spinning. Once traction is broken, they are relatively free to swing laterally. Under braking load, more work is typically done by the front brakes. If this forward bias is too great, then the front tyres may lose traction, causing understeer.
