Abstract
Abstract A vehicle safety or caution sign is attached to the side of a vehicle. The sign is held by an elongated member which is coupled by a first pivot to a mounting member that attaches to the vehicle. The first pivot enables the sign to be swung in a fore and aft direction relative to and toward and from the vehicle. The sign has a bearing member secured thereto and which operates as a second pivot and is coupled with the elongated member to enable the sign to hang in a generally vertical position when the vehicle is moving at a slow speed or is stopped, and to enable swinging of the sign to a generally horizontal position when the vehicle is moving in excess of a predetermined speed.
