Texas Intrastate Operating Authority: The TxDMV Certificate

If you only haul inside Texas, you may think your USDOT number is all you need. It is not. Texas intrastate operating authority comes from the Texas Department of Motor Vehicles (TxDMV), and it is a separate step. TxDMV says it plainly: a USDOT number "is not operating authority." Here is who needs the TxDMV certificate and how to get it.

USDOT number vs Texas intrastate operating authority

Think of it like this:

• USDOT number. An ID number from FMCSA, the federal trucking safety agency. TxDMV calls it basically an identifier.
• TxDMV certificate (TxDMV number). Your permission to operate as a motor carrier inside Texas. Many people still call it the old "TxDOT number."
• MC number. Your federal operating authority if you haul for hire across state lines.

If you run only inside Texas, from Laredo to Houston or around the Rio Grande Valley, the TxDMV certificate is the one that matters for state authority. If you cross state lines, you deal with the federal side too. Our USDOT number guide explains the federal ID.

Who needs Texas intrastate operating authority

According to TxDMV, you must register if you operate in Texas with, among other cases:

• A commercial motor vehicle, or a combination, with a gross weight, registered weight or gross weight rating over 26,000 pounds.
• Vehicles that haul hazardous materials that need registration.
• Vehicles designed to carry 16 or more passengers.
• Household goods moves for pay.

TxDMV lists other cases too, like certain farm vehicles and school buses. If you are not sure, check the TxDMV page or call us before you haul.

How to get your TxDMV certificate, step by step

1. Get your USDOT number first. TxDMV lists this as the first step.
2. Apply in TxMCCS. That is the Texas Motor Carrier Credentialing System, TxDMV's online system for motor carrier credentials.
3. Pick your term. TxDMV says registration is available for seven calendar days, 90 days, one year or two years.
4. Get your insurance filed. TxDMV requires proof of insurance filed electronically. For commercial auto, that filing is called a Form E. Your insurer sends it to TxDMV, not you.
5. Wait for approval, then keep a copy of your certificate.

Insurance filing: the step that must stay current

TxDMV sets minimum liability amounts by type of carrier. For standard commercial motor carriers over 26,000 pounds, TxDMV lists $500,000. Hazmat and household goods carriers have different amounts.

The key warning from TxDMV: you are responsible for making sure your insurance stays filed with TxDMV "24/7." If the filing is cancelled or lapses, your authority can be affected. When you change insurance companies, make sure the new filing is in place before the old one ends.

Keep your records in one place

Once you have your certificate, treat it like any other key document. Keep in one folder, paper or digital:

• Your TxDMV certificate and its end date.
• Your USDOT number and your login for FMCSA's systems.
• Proof that your insurance filing is on record with TxDMV.
• Your truck registrations and your driver files.

Put the end date of your certificate on your phone calendar with a reminder a few weeks before. A short-term certificate is easy to forget.

Mistakes to avoid

• Thinking the USDOT number is enough to haul inside Texas.
• Letting a short-term certificate expire without renewing.
• Changing insurance without checking the Form E filing.
• Not updating TxDMV when your address, trucks or business name changes.
• Starting interstate work without the federal authority you need.
