Hotshot Trucking DOT Number Decals for Pickups and Trailers

Hotshot trucking DOT number decals come down to weight, because a pickup that is under the line on its own can cross it with a trailer behind it. The federal definition looks at the combination, 10,001 pounds or more, for a vehicle used in interstate commerce. If your rig reaches that, the pickup doors carry your name and USDOT number, and the trailer carries whatever unit or weight decals you choose.

Why combination weight matters

The definition of a commercial motor vehicle (49 CFR 390.5T) uses the gross vehicle or combination weight rating, or the actual gross weight, whichever is greater. The combination rating is the greater of the maker's figure for the power unit or the truck's rating plus the rating of each towed unit. The power unit's own combination figure is not used when it is not towing.

FMCSA guidance applies the same logic to a truck and trailer that are each rated under 10,001 pounds but add up past it (FMCSA). We do not quote weights for any rig here. Find the ratings on the manufacturer's labels for your truck and trailer and add them up.

States can use their own lines for runs that stay inside the state, so check with yours (FMCSA). Our pickup truck guide goes through the cases.

When for-hire loads need MC

Hauling a customer's freight for a fee across state lines is the case FMCSA describes as generally needing operating authority, an MC number, on top of a USDOT number. Private carriers hauling their own cargo are listed as not needing one (FMCSA). Read that page against your own freight, and see our MC vs USDOT guide.

Layouts for pickup doors

Measure the door and tape up the spot before you pick a width, since a window and a body line cut into the flat area. The marking rule covers the pickup on both sides, so you need a pair.

• USDOT + MC Two-Line: a compact two-line stack, $16.99 per decal.
• Custom USDOT Logo: name, city, USDOT and MC on one rectangle, $26 per decal.

Widths of 12, 18 and 24 inches describe the decal, not a legal letter height, and wider ones add $6 or $14 in the builder. The live preview in the door builder shows how the lines sit on a door.

Decals for the trailer

The federal marking rule applies to the self-propelled vehicle, and FMCSA's 2000 rule did not extend it to trailers (Federal Register). Trailer decals are therefore your own identification:

• Trailer / Unit Number pair: unit numbers plus a GVWR line, $18.99.
• GVW / Weight Decal: one weight line, $12.99.

Gooseneck or bumper pull, flatbed or deckover, the pickup's door lettering does not change with the trailer. Some states have their own weight-marking rules, covered in our GVWR sticker guide.
