Pro-safe 07-800-3717-L Shoulder Work Ahead Triangle Sign

Product Description

The PRO-SAFE 07-800-3717-L is a triangular traffic control sign printed with the legend "Shoulder Work Ahead" for use in roadway and workzone safety applications. Constructed from vinyl with an uncoated, non-reflective finish, this sign measures 36 inches in height and 36 inches in width and weighs 3 pounds. It mounts to a standard sign stand and deploys quickly, making it practical for temporary traffic control setups managed by road crews, utility workers, and municipal maintenance teams. The single printed face displays a black-and-orange message-only graphic in compliance with MUTCD standards and NCHRP 350 certification requirements.

This sign is suited for temporary traffic control zones where shoulder work activity requires advance warning to approaching drivers. Typical applications include highway shoulder maintenance, utility line work adjacent to travel lanes, and municipal road repair operations. The quick-deploy design reduces setup time in the field. It is intended for sign stand mounting and is appropriate for both short-duration and longer-term workzone configurations managed by flagging crews or traffic control supervisors.

Installation Notes

Installation is typically performed by trained flaggers or traffic control supervisors following applicable MUTCD guidelines for temporary traffic control zones. Secure the sign firmly to the stand mount before positioning in the work area to prevent displacement by vehicle-induced air turbulence or wind. Inspect the sign face and mounting hardware before each deployment to confirm the legend remains legible and the mount is undamaged. Follow all applicable federal, state, and local workzone safety regulations when positioning signs relative to the work activity.
