Description
The W13-1P advisory speed plaque is used with applicable temporary traffic control warning signs to recommend a safe travel speed through the work area. Black "20 MPH" legend on an orange retroreflective background. This is an advisory speed for the work-zone condition, not a regulatory speed limit.
This listing is for the 20 MPH version. Other speed options are available as separate listings. Our 12" x 12" suits short-term work on private property, and the 18" x 18" is the smallest size meant for a public road. The 24" x 24" is standard for conventional roads. The 30" x 30" is for expressways and freeways. Mounts below the associated warning sign on the same post. Hardware sold separately.
