State Route marker sign

What to do

Learn your state's marker design and use it to follow state routes.

Learn your own State's marker shape so you can quickly tell a State route from a U.S. or county route in a cluster of signs.

Commons file shows the generic MUTCD design; real designs vary by state.

Where it's used

Section 2D.11 says State Route signs are designed by each State highway agency, using the standard sign alphabets. They should be rectangular and about the same size as the U.S. Route sign, with black numbers on a white area set on a black background without complex graphics, and the white area should be a circle unless the State chooses another shape. On green guide signs only the distinctive shape and numbers are shown.

Don't confuse it with

• U.S. Route marker: The U.S. Route marker always uses the same white shield on black, while State markers vary from State to State.
• County Route marker: The County Route marker is a blue pentagon with yellow lettering.
• Interstate Route marker: The Interstate marker is a red, white and blue shield.
