Abstract: A warning sign that is attached to a spring-loaded roller contained in a housing, which is then secured to the truck or trailer. When the sign must be displayed, the driver simply pulls the sign from the housing and extends it across the vehicle's bumper. When it is fully extended, the free end is secured to mounting fasteners located on the vehicle. In this way, the sign is ready for use, clean and in good condition. After the load has been hauled and the sign is no longer needed, it can be released and rolled back inside the housing, ready for the next use. The housing can be installed on trucks, pilot vehicles, heavy equipment, and trailers and can be deployed whenever needed simply be pulling the sign out and securing it to the vehicle.
