Abstract
A roadway pavement marker protective member defined by a single rail for the protection of pavement markers. A pavement marker is placed on the roadway surface and one or two of these rails are placed about the pavement marker for its protection. The protective member deflects potential hazards presented by oncoming traffic, such as snowplow machines, from the pavement marker and prevents it from being dislodged.
