Advisory Speed Sign Blank W13-1P

The W13-1P is a supplemental plaque that mounts below a warning sign to recommend a safe speed for the condition ahead. This is the blank version: a black "MPH" legend on a yellow retroreflective background with the speed number left blank for field marking. Commonly paired with turn signs (W1-1), curve signs (W1-2), and other advance warning signs where a speed reduction is advised.

This is an advisory speed plaque, not a regulatory speed limit sign. A 12" x 12" version is available for compact warning assemblies on private grounds, with the number filled in on site. Standard size is 18" x 18" per MUTCD specifications. Larger 24" x 24" and 30" x 30" plaques are also sold for bigger sign assemblies.

Mounts directly below the associated warning sign on the same post. Sign post, mounting hardware, and brackets are sold separately.
