Grooved Pavement Warning Sign - W8-15

The W8-15 warns drivers, and especially motorcyclists, of a grooved pavement surface ahead. Black GROOVED PAVEMENT legend on a yellow retroreflective background. Used under MUTCD Chapter 2C where longitudinal grooving can affect handling. Five sizes are currently available. On private drives and lots where milled or grooved strips can unsettle motorcycles, the 18" x 18" is the compact choice. The 24" x 24" is for low-volume roads with speed limits of 30 MPH or less. The 30" x 30" is for single and multi-lane conventional roads. The 36" x 36" is for expressways and high-speed roadways. The 48" x 48" is for freeways. Sign post, mounting hardware, and brackets are sold separately.
