About Object Markers
The purpose of object markers is to mark obstructions located within or adjacent to the roadway including underpass piers, bridge abutments, handrails, ends of traffic barriers, utility poles, and culvert headwalls. Other roadside conditions, such as narrow shoulders, drop-offs, gores, small islands, and abrupt changes in the roadway alignment, that might make it undesirable for a road user to leave the roadways, also create a need for a marker. Refer to the MUTCD for more information.
