Object Markers

Use object markers to mark obstructions within or adjacent to the roadway. There are four types of object markers, Type 1, Type 2, Type 3, and Type 4.

Objects in the roadway should be marked with a Type 1 or Type 3 marker. Type 3 markers shall have stripes pointed downward on the side traffic should pass.

Objects adjacent to the roadway should be marked with Type 2 or Type 3 markers. These include underpass piers, bridge abutments, handrails, and culvert headwalls. In some cases they may be used to mark roadside conditions such as narrow shoulder drop-offs, gores, small islands, and abrupt changes in roadway alignment.

The Type 4 object marker is used to warn and alert road users of the end of a roadway.
