ABSTRACT:
A control device carried beneath the fifth wheel of the tractor or truck of a tractor-trailer vehicle and coupled to the trailer, in which dangerous lateral movements of the trailer with respect to the tractor while under way are prevented by arresting means responsive to the vehicle brakes applied during the initial lateral movement of the trailer. The lateral travel of the trailer is stopped before it can reach a point beyond which it cannot be returned to a normal position and which might result in jackknifing. The device acts upon normal vehicle brake application by the driver and without regard to the direction or directions of lateral movement.
