Frequently Asked Questions

Q. Can I set my own speed limit on a custom speed limit sign?

Yes - a custom speed limit sign lets you choose any number (5, 8, 12, or 15 MPH, for example) that fits the safety needs of your private parking lot or roadway. They are often used to slow drivers in high-pedestrian areas like warehouse docks and apartment complexes.

Q. Are custom speed limit signs legally binding?

Custom speed limit signs are enforceable based on where they're posted. On public roads, speed limits are set by state and local governments after engineering and traffic studies, so a sign can't lower a public-road limit on its own. On private property, a custom speed limit sign is set and enforced by the owner - which is why parking lots, HOAs, and campuses post their own.

Q. Do custom speed limit signs look like official DOT signs?

Custom speed limit signs are printed in the official MUTCD "R2-1" layout with FHWA fonts, so they read like real regulatory signs instead of a suggestion. A custom speed limit sign built to that standard carries the same visual authority drivers already obey on public roads.

Q. What material is best for a custom speed limit sign?

A custom speed limit sign has to stand up to years of weather and still show its posted number, so the best material is rustproof.080" aluminum. A speed limit sign on aluminum bolts to a post or wall, won't rust, and keeps its MPH legible for 10-15 years - which is why parking lots and private roads choose aluminum speed limit signs over plastic ones that crack and fade.

Q. What size should a custom speed limit sign be?

Custom speed limit sign sizes follow the MUTCD by road type. The standard on a conventional two-lane road is 24" x 30", stepping up to 30" x 36" on multi-lane roads and larger on expressways and freeways, with a minimum of 18" x 24". On a private road, parking lot, or driveway, a smaller 12" x 18" custom speed limit sign works fine.

Q. Why are speed limit signs only in multiples of 5 MPH?

On public roads, the MUTCD requires speed limits in 5 MPH increments, which is why most speed limit signs read 15, 25, or 35. On private property, you're not bound by that rule - a custom speed limit sign can post an odd number like 14 MPH, a trick some parking lots use to make drivers actually notice the sign.

Q. Do I need approval to post a custom speed limit sign?

On your own private property, you can post a custom speed limit sign without state approval, since governments set limits only for roads open to public travel. It's still worth checking local ordinances, which can regulate sign size and placement even on private land. On a public road, the limit and its sign are set by the local traffic authority, not by a private order.
