Pro-safe 07-800-4039-L Triangle Slow Traffic Control Sign

Product Description

The PRO-SAFE 07-800-4039-L is a triangular slow traffic control sign designed for roadway work zones, construction sites, and flagging operations. Built from reflective vinyl, it delivers high-visibility orange and black messaging to approaching drivers in both daytime and low-light conditions. At 48 inches tall and 48 inches wide, this single-sided sign mounts on a standard sign stand and deploys quickly during active traffic management operations. It meets MUTCD requirements and is NCHRP 350 certified, making it compliant for use on federally funded roadway projects. Traffic control flaggers, road construction crews, and safety personnel are the primary installers.

This sign is suited for temporary traffic control applications in residential, commercial, and highway construction environments. The quick-deploy feature reduces setup time during lane closures, utility work, and paving operations. The sign stand mount design is compatible with standard portable sign stands used across the traffic control industry. Its uncoated reflective vinyl construction holds up in typical outdoor field conditions throughout a work zone deployment.
