Pro-safe 07-800-3700-L Traffic Control Sign Triangle 36 in

Product Description

The PRO-SAFE 07-800-3700-L is a triangular traffic control sign designed for temporary roadway and workzone applications. Printed with a black-on-orange "Be Prepared to Stop" message on a single face, this vinyl sign mounts to a standard sign stand for rapid field deployment. At 36 inches tall and 36 inches wide with a nominal thickness of 0.1 inches, it provides a clear, high-visibility warning to approaching motorists. The uncoated vinyl construction keeps weight to 3 pounds, making it easy to transport and stage. Flaggers, traffic control supervisors, and road crew leads are the primary installers of this sign.

This sign is suited for temporary traffic control (TTC) zones in residential, commercial, and municipal roadwork settings. It deploys quickly on standard portable sign stands without additional hardware. The single-sided printed face is oriented toward oncoming traffic to communicate lane slowdowns, merge warnings, or stop-flagger operations ahead. The quick-deploy feature supports efficient staging and breakdown during short-duration or mobile operations. Typical users include highway maintenance crews, utility contractors, and municipal public works departments.

Compatibility

Designed for use with standard portable sign stands accepting a sign stand mount interface. Intended as a temporary traffic control sign per MUTCD guidelines for roadway work zone applications.

Installation Notes

Installation is performed by certified flaggers or traffic control supervisors in accordance with the applicable MUTCD temporary traffic control plan. Secure the sign firmly to the stand mount before positioning it in the travel-way environment to prevent wind displacement. Because this sign is non-reflective, supplemental lighting or additional reflective devices are required for nighttime or low-visibility work zone compliance. Remove and store the sign flat to avoid creasing the vinyl face.
