The Diagonal Downward Left Arrow Plaque (W16-7PL) is a warning traffic sign plaque used to provide supplemental directional guidance for channelization, lane shifts, or roadway alignment changes. Commonly installed beneath warning signs such as chevrons, object markers, or alignment signs, this 24" x 12" plaque directs traffic diagonally downward to the left to safely navigate obstructions or roadway transitions. Manufactured to MUTCD standards, it offers high visibility, durability, and long-term performance for municipal, contractor, and commercial roadway safety applications.
