A reflective roadway delineator for reflecting incident light directed thereon by an oncoming vehicle back to the vehicle, the delineator being capable of being mounted upon either a roadway barrier having a planar longitudinally extending surfaces thereon or in the generally U-shaped trough of a longitudinally extending highway guard rail. The delineator comprises a base member having at least two different mounting surfaces thereon. One of the surfaces is engageable with and complementary to a planar surface of the associated barrier and the other of the surfaces is complementary to and engageable with at least one wall defining the recess of the trough in the associated guard rail. A reflex reflector is fixedly carried by the base member at predetermined angles relative to the mounting surfaces. The reflex reflector, the base member and the mounting surfaces are configurated and arranged such that the reflex reflector will be positioned at substantially the same operating angle relative to the longitudinal axis of either of the associated barrier or guard rail, regardless of whether the delineator is affixed to the barrier planar surface or in the trough of the guard rails. Means is associated with at least one of the mounting surfaces for securing the delineator to the respective associated guard rail or the associated barrier.
