Box Truck Authority: Do You Need a DOT and MC Number?
By Authority Launcher · Updated October 29, 2026
Quick answer: If you haul freight for pay across state lines in a box truck rated over 10,001 lbs, you need a USDOT number and MC authority, at least $750,000 in liability insurance filed with FMCSA, a DOT medical card, and you must follow hours-of-service rules. Box trucks rated 26,000 lbs or less can be driven without a CDL, which is why the 26-foot, 26,000 lb box truck is popular for new businesses.
Requirements by truck rating
| Box truck GVWR | CDL? | USDOT (interstate) | MC (for-hire interstate) |
|---|---|---|---|
| 10,000 lbs or less | No | Assigned with your MC authority if you're for-hire | Yes, if for-hire interstate (lower insurance minimum) |
| 10,001 to 26,000 lbs | No | Yes | Yes |
| 26,001 lbs or more | Yes, Class B | Yes | Yes |
Many states also require their own number for intrastate work, so check your state's rules if you'll stay local.
Why the 26,000 lb box truck is popular
- No CDL required, so more drivers can operate it.
- No federal drug and alcohol testing program (that applies to CDL drivers).
- A two-axle truck at 26,000 lbs or less is usually not an IFTA or IRP qualified vehicle.
- No Form 2290 heavy vehicle use tax (that starts at 55,000 lbs taxable gross weight).
You still need a medical card, hours-of-service compliance (and an ELD unless exempt), insurance filings, a BOC-3 and UCR.
Steps to get box truck authority
- Form your business and get an EIN.
- Apply for your USDOT number and MC authority in FMCSA's Motus system ($300 per authority type). See how to get an MC number.
- Bind insurance and have your insurer file BMC-91 or BMC-91X. See insurance requirements.
- Have a process agent file your BOC-3.
- Register for UCR.
- Confirm your authority is active on SAFER before hauling.

Yes, if you haul regulated freight for pay across state lines. If you only haul your own goods or stay within one state, you may not, but check your state's requirements.
Do I need a CDL for a 26-foot box truck?
Not if its GVWR is 26,000 lbs or less and you don't haul placarded hazmat. At 26,001 lbs or more you need a Class B CDL.
