Abstract
Guardrail delineators include a flag portion and a depending leg portion. One side edge of the leg portion has a notch axially spaced from the flag portion. The top surface of the notch is engageable with a top edge of the guardrail or a top edge of the support structures for the guardrail for positioning the flag portion a predetermined height above the guardrail. The one side edge of the leg portion axially outwardly of the notch extends perpendicular from the inner end of the notch and is engageable with the back side of the guardrail or support structures for providing proper vertical alignment of the delineators with respect to the guardrail.
