The 48" x 48" Be Prepared To Stop sign is a roll-up traffic control device designed for advance warning placement in work zones. This MUTCD W3-4 regulatory sign alerts motorists to upcoming lane closures, flagging operations, or temporary stops ahead.
Constructed with orange hi-intensity reflective vinyl on a flexible substrate, this sign delivers high visibility in daylight and nighttime conditions. The roll-up design allows compact storage and quick deployment, making it ideal for mobile work crews who need to set up and tear down traffic control multiple times per day. Heavy-duty plastic pockets secure fiberglass support ribs (included) that maintain the sign's shape when deployed.
