Shoulder Closed Signs

Shoulder Closed signs warn drivers that a road shoulder is unavailable ahead, while Shoulder Work signs identify maintenance or equipment operating beside the travel lanes. Our MUTCD W21-5 selection includes left and right shoulder closure warnings, Ahead and distance messages, and blank distance versions for matching the sign to your work zone setup.
