Official Highway Signs

Yes, the highway signs on this page are built to MUTCD specifications, covering the required shape, color, legend, and reflectivity for each sign type. Shoppers can also browse the full MUTCD-compliant sign collection to confirm a specific sign meets federal standards before ordering.

Yes, custom highway signs are available for situations like route markers, city limit signs, or distance signs that need specific text, numbers, or wording added. Custom highway signs are made from the same rustproof aluminum and reflective materials as standard stock signs, so durability isn't affected by customization.

Highway sign size depends on the type of sign and the speed of the road it's posted on, since MUTCD sets separate minimum sizes for conventional roads versus expressways and freeways. As a general rule, higher-speed roads require larger signs to give drivers enough distance to read and react, so checking the MUTCD size table for the specific sign type is the best way to confirm the correct size.

Installing an official highway sign on a public road typically requires approval from the local or state transportation department, since public roadways fall under that agency's jurisdiction. Highway signs installed on private property, such as a private road or driveway, generally don't require a permit, though local zoning rules can still apply.
