The 48" x 48" Orange Hi-Intensity Reflective Vinyl Roll-Up Sign displays the Reverse Curve Left (W1-4L) symbol to warn motorists of upcoming left-curving roadway geometry. This portable traffic control sign is designed for temporary work zones, road construction projects, and emergency traffic management where permanent signage is impractical.
Constructed with hi-intensity grade reflective vinyl sheeting on a durable substrate, this roll-up sign delivers superior visibility in day and night conditions. The flexible design allows the sign to be rolled for compact storage and transport, then quickly deployed on tripod stands, sign frames, or barricade-mounted brackets. Bright orange background with black legend meets MUTCD standards for temporary traffic control devices.
