Interstate Carrier ResourcesHow to Get an MC Number for a Cargo Van, Box Truck, or Hotshot Truck
Reviewed by Austin Park, founder of ICR Filings · Updated October 21, 2026
- Hauling for hire across state lines needs MC authority at any weight, even in a cargo van.
- At 10,001 lbs or more (truck and trailer combined), you also need a USDOT number on weight alone, and the liability minimum rises from $300,000 to $750,000.
- Over 26,000 lbs, drivers generally need a CDL, which brings drug testing and the Clearinghouse.
- A hotshot pickup under 10,001 lbs alone is often over it once a loaded trailer is hooked up.
Plenty of people start trucking with a cargo van, a box truck, or a pickup and gooseneck. The federal rules turn on two things: whether you haul for hire across state lines, and how heavy the vehicle is. Here is what each setup needs.
The two weight lines that matter
- 10,001 lbs: at or above this weight rating (truck and trailer combined), interstate operation requires a USDOT number, and the insurance minimum for general freight rises from $300,000 to $750,000.
- 26,001 lbs: above 26,000 lbs, drivers generally need a CDL, which brings drug and alcohol testing and the Clearinghouse.
What each setup needs
| Setup (for hire, interstate) | USDOT | MC authority | Liability minimum |
|---|---|---|---|
| Cargo van or small box truck under 10,001 lbs | Issued with your authority application | Yes | $300,000 |
| Box truck 10,001 to 26,000 lbs | Yes | Yes | $750,000 |
| Hotshot (pickup plus trailer) 10,001 lbs or more combined | Yes | Yes | $750,000 |
| Hotshot or box truck over 26,000 lbs | Yes | Yes | $750,000, plus CDL rules |
The weight that counts is the weight rating on the door sticker (GVWR), or the combined rating (GCWR) for a truck and trailer, or the actual weight if that is higher. A hotshot pickup that is under 10,001 lbs alone is often over it once you hook up a loaded trailer.
When you do not need an MC number
- You only haul your own goods (a private carrier, like a contractor moving its own tools).
- Everything stays in one state, start to finish, and is not part of a longer interstate move. Your state may have its own rules.
- You only haul exempt commodities, such as certain unprocessed agricultural products.
- You are leased onto a carrier and run under its authority. See lease on vs your own authority.
How to get it
- Apply in Motus for a USDOT number and for-hire carrier authority ($300 FMCSA fee).
- Have a process agent file your BOC-3.
- Buy insurance at or above the minimum for your vehicle and have the insurer file it with FMCSA (BMC-91 or BMC-91X).
- Wait for the protest period and FMCSA's grant, then register for UCR.

Common questions
Do I need an MC number for a cargo van?
Yes, if you haul other people's freight for pay across state lines. FMCSA issues a USDOT number with your authority application, and the liability minimum is $300,000.
Does a hotshot need a USDOT number?
If the truck and trailer weight rating combined, or the actual weight, is 10,001 lbs or more in interstate commerce, yes. Most hotshot setups reach that once a loaded trailer is attached.
How much insurance does a hotshot need?
For-hire general freight at 10,001 lbs or more needs at least $750,000 in liability coverage, filed with FMCSA by your insurer.
Does a box truck need a CDL?
Generally only over 26,000 lbs. Box trucks of 26,000 lbs or less usually do not, but still need a USDOT number and authority for for-hire interstate work at 10,001 lbs or more.
When do I not need an MC number?
If you only haul your own goods, everything stays within one state and is not part of an interstate move, you only haul exempt commodities, or you are leased onto a carrier and run under its authority.
