The short answer
Trucks based in Minnesota: the USDOT number when it hauls for hire or is 10,001 lbs or more.
Minnesota is broad: FOR-HIRE motor carriers mark the name + USDOT number regardless of vehicle weight (limousines on LM plates excepted), and private carriers join at 10,001 lbs. Both sides, readable from 50 feet.
Trucks that cross a state line, or haul freight that starts or ends in another state, follow the federal rule instead: the USDOT number and your legal name when it is 10,001 lbs or more, carries placard-level hazmat, seats 9 or more for hire or seats 16 or more (49 CFR 390.21T(b)(2)).

USDOT number required
The Minnesota rule reaches this truck because it hauls for hire and is 26,000 pounds, over the 10,001-pound line.

On the door that reads: USDOT 1234567 · Your Company LLC. Because it hauls for hire across state lines, the checker also lists the MC number as commonly displayed but not required.
The checker weighs rating, registered and actual weight, operation, for-hire status, cargo, passenger count and farm status. It does not model axle count or vehicle type, so if your truck is unusual, confirm with MnDOT — Office of Freight & Commercial Vehicle Operations.
What goes on the door in Minnesota
- One marking, both sides of the power unit: USDOT 1234567, which is the USDOT number.
- No inch minimum in Minnesota. The legal standard is a color that contrasts with the truck and letters readable from 50 feet in daylight. We cut 2-inch letters, which clears that bar on any door.
- Interstate too? The Minnesota rule is not limited to in-state trucks, and the federal markings are the same USDOT number and legal name, so one set serves both.
Across the Minnesota line
The Minnesota line only matters while the truck stays home. One job in Wisconsin, or one load that starts or ends out of state, makes it interstate commerce, and the federal 10,001-pound rule applies no matter where either state draws its own line. For a truck that works near the border it helps to know how the neighbors differ for their own in-state trucks:
- Iowa: for-hire carriers at any weight.
- North Dakota: 26,001 pounds.
- South Dakota: 26,001 pounds.
- Wisconsin: the federal 10,001 pounds even in-state.
Neighbor lines come from the same verified rule files the checker uses; each state's page has its citations.
Who enforces it in Minnesota
Door markings in Minnesota are the business of MnDOT — Office of Freight & Commercial Vehicle Operations. Questions about your registration or number: (651) 215-6330, agency site. The federal side, USDOT numbers and the MCS-150, is the FMCSA Minnesota Division: (651) 291-6150, MCMNOFF@dot.gov. A marking violation is written at the roadside and follows the carrier on the inspection report, which is why it is worth getting the two lines right the first time.
For the marking mistakes inspectors catch most often, see USDOT marking mistakes that fail roadside inspections.
