Dump Truck DOT: What Goes On the Door

Dump trucks are almost always over the line

The federal line for a commercial motor vehicle is 10,001 lbs, by weight rating or actual loaded weight, whichever is greater (49 CFR 390.5T). A dump truck is almost always rated past that. Many are rated past 26,000 lbs, which is above the highest intrastate weight line any state uses in our verified data.

So the real questions for a dump truck aren't about weight. They're about where you run, and which extra lines your state adds.

Interstate: the federal rule

If your dump truck crosses a state line for work, it shows your legal name or single trade name, exactly as on your MCS-150, plus "USDOT" and your number. Both go on both sides of the power unit, in a sharply contrasting color, readable from 50 feet in daylight (49 CFR 390.21T). No inch height is named federally.

Intrastate: your state's rule

If your dump work stays inside one state, your state's rule is the one that matters. From our verified state data, in-state trucks need name + USDOT markings at 10,001 lbs in states like Georgia, Illinois, New York and South Carolina, at 17,001 in Pennsylvania, at 18,001 in Connecticut, and at 26,001 in states like Nevada, Texas, Florida and Arizona.

A tandem rated over 26,000 lbs clears every one of those lines. A smaller single-axle dump rated, say, 19,500 lbs is where it gets state-specific: marked in Georgia, not required under Nevada's in-state weight rule. Farm trucks get exemptions in several states, but not always: Texas only exempts farm vehicles under 48,000 lbs (Tex. Transp. Code 548.001). The 50-state marking table has your state with its source.

Extra lines some states add

• State suffix. In-state carriers in Georgia, South Carolina, North Carolina, Montana, Wyoming and several others add letters after the number, like USDOT 1234567 GA. North Carolina also sets 3-inch minimum letters for in-state trucks over 26,000 lbs (N.C.G.S. 20-101(b)). See state suffix letters.
• A GVWR line. New Jersey trucks rated 26,001 lbs and up display the GVWR in letters at least 3 inches tall, along with the owner's name and town (N.J.S.A. 39:4-46). See New Jersey.
• California carrier number. Required on trucks over 10,000 lbs. A displayed USDOT number satisfies the law (CVC 34507.5), but industry practice, and our recommendation, is to run both lines. See California.
• Florida farm dumps. Trucks under Florida's agricultural exemption show the owner's name and home town at 26,001 lbs, or with 3+ axles at any weight (Fla. Stat. 316.302(2)(e)).
• Contractor licenses. If you hold one, ask your licensing board whether it has a vehicle rule. That's separate from DOT marking and not in our verified data.

Where it goes on a dump truck door

• Company name on top, USDOT below, centered on the flat part of each door. Do the passenger side too.
• Stay above the lower body line. The bottom of the door takes mud and gravel spray. Keep lettering clear of steps, grab handles and mirror brackets.
• Measure first. We recommend 3-inch lines on a dump truck door. At 3 inches, USDOT 1234567 runs about 31 inches wide. Narrow door? We stack USDOT above the digits on the proof at no charge.
• Contrast. Black on a white or yellow cab, white on a dark one.

Bought a used truck? Strip the old company's lettering before yours goes on. California gives you 60 days to remove or cover a previous owner's name (CVC 27900(d)). Our removal guide covers the job.

Vinyl that survives the job

Dump trucks get pressure-washed, sandblasted by their own load, and baked on job sites. We cut premium outdoor vinyl rated 5+ years, with a free digital proof first, free U.S. shipping, and shipping 1-2 business days after you approve (3-5 for 30+ sets with multi-color logos). Degrease the door before you apply, and apply between about 50 and 90 degrees F. Let it sit a few hours before the first wash, and keep a pressure-washer tip back from the letter edges.

A "stay back" tailgate decal is a popular add-on. It's an optional warning to following drivers, not a marking requirement, and it's no guarantee on windshield claims. See our stay back decals.
