Object Marker Signs
Object Marker Signs (MUTCD OM1 through OM4) mark obstructions in or near the roadway and the ends of roadways. Yellow and yellow/black markers identify obstructions; red and red/black markers identify where a road ends. Rice Signs carries all four MUTCD types plus black and red stripe variants, on rust-proof .080" aluminum with pre-drilled mounting holes at top and bottom.

What are Object Markers?
Object Markers are warning signs that mark obstructions in or near the road, as well as mark the end of a road. Obstructions located on or near roadways are marked with yellow or yellow/black Object Markers, while Object Markers that mark the end of a roadway are red or red/black.
Who uses Object Markers?
Municipalities and highway contractors use Object Markers to mark obstructions in urban and rural areas. Private landowners may place several Object Markers to highlight the perimeter of their property.
What other traffic signs are used with Object Markers?
Object Markers are typically used as standalone traffic devices. Occasionally, the R4-7 Divided Highway Sign is used together with the OM1 series of Object Markers.
What modifications are available?
In the past, we have manufactured OM1-2 and OM4-2 Object Markers where full-cube prismatic sheeting takes the place of the yellow and red acrylic reflectors. This modification makes Object Markers compliant with certain local jurisdiction requirements.
How are object markers named?
Each sign has a unique SKU that starts with the letters OM, which stands for Object Marker, and is followed by a single number from 1 to 4, defining one of the four main types it belongs to. For example, the OM1-3 would be a Type 1 sign, while the OM4-1 would be a Type 4 sign. The final number after the dash in the SKU distinguishes one sign from another.
What Object Marker Type do I need?
The MUTCD provides basic guidance on what Type of Object Marker to use. For Type 1, Type 2, and Type 4 Object Markers, which style to use is left to state and local jurisdiction preference. Type 3 Object Markers have three similar but distinct uses based on the direction of the sloping lines (2C.71, 04): OM3-L is used when traffic should pass to the right, OM3-C when traffic can pass either to the left or to the right, and OM3-R when traffic should pass to the left.
What is the mounting height for Object Markers?
In most cases, Object Markers have a mounting height of 4 ft. or more onto obstructions (2C.70, 04, 05). However, MUTCD guidance acknowledges that the mounting height may vary depending on the height of the obstruction (2C.70, 07).
What mounts are commonly used with Object Markers?
Object Markers are generally installed directly onto the obstruction. However, at the end of a roadway, Type 4 Object Markers are often mounted onto Type 3 Barricades with red and white stripes.
What are the reflectivity and material options available?
Object Markers are generally made with .080 inch aluminum that has pre-drilled holes at the top and bottom for easy mounting. High Intensity Prismatic and Ultra Prismatic are the two most common reflective materials.
Where can I find more information about Object Markers?
Chapter 2C in Part 2 of the MUTCD contains more information about Object Markers, including 2C.70 (design and placement height), 2C.71 (obstructions within the roadway), 2C.72 (obstructions adjacent to the roadway), and 2C.73 (ends of roadways).
