OM Series — Object Markers

The OM Series covers object markers — retroreflective warning devices used to delineate physical obstructions in or adjacent to the traveled way. OM1-3 (Type 1 object marker), OM2-2V (Type 2 vertical object marker), and OM3-L (Type 3 object marker) are used in California TCPs to mark bridge ends, island noses, channelizing device faces, guardrail ends, and other fixed hazards that drivers could strike. Object markers provide critical nighttime delineation in work zones.
