Regulatory & Commercial Delineators

  • Road delineators are light reflecting devices mounted along the side of a roadway intended to be used as guidance devices to indicate road alignment changes, rather than warning devices.
  • Street delineator color must conform to the color of the pavement edge line on the side of the road where the delineators are placed (MUTCD Section 3B.01 and 3B.04.)
  • Please note, different states may have different delineator posting requirements.
  • We carry the most popular color combination, Yellow/Black in 2 sizes (12 x 36" & 8 x 24") to comply with MUTCD, the other colors are for commercial, off-the-street use and are available only in 8 x 24".
