What Is a USDOT Number?
A USDOT number is a unique identifier used by the Federal Motor Carrier Safety Administration (FMCSA) to monitor a carrier’s safety and compliance performance. This includes:
- Roadside inspections
- Crash investigations
- Safety audits
- Compliance reviews
- Recordkeeping and Hours-of-Service tracking
If you’re unsure about how a USDOT number differs from an MC number, we’ve broken it down in detail here: What’s the Difference Between a MC Number and USDOT Number.
The USDOT number stays with your company and must be updated if your operation type, business address, or number of vehicles changes.
Who Needs a USDOT Number in Louisiana?
You are required to have a USDOT number if:
- Your commercial vehicle has a Gross Vehicle Weight Rating (GVWR) or Gross Combination Weight Rating (GCWR) over 10,000 lbs
- You cross state lines while transporting cargo or passengers (interstate commerce)
- You transport hazardous materials in quantities that require placarding, even if operating only within Louisiana
Louisiana-based intrastate carriers may also need a USDOT number depending on the type of freight and the vehicle being used.
Louisiana USDOT Number Rules & Enforcement
In Louisiana, USDOT compliance is regulated by the Louisiana Department of Transportation and Development (LaDOTD) in coordination with the FMCSA. Failure to obtain or maintain a valid USDOT number can result in fines, registration delays, and being placed out of service.
Common industries in Louisiana that typically require a USDOT number include:
- General freight hauling
- Agriculture and livestock transport
- Oilfield and equipment transport
- Dump truck and construction vehicle operations
- Hazardous materials transport

How to Apply for a USDOT Number in Louisiana
All new registrations go through the FMCSA’s Unified Registration System (URS), which requires accurate business and operational data. As part of the process, you’ll need:
- Legal business name and contact details
- Employer Identification Number (EIN) or Social Security Number (SSN)
- Details about your vehicle(s): weight, use, number of units
- Operation classification: for-hire, private, broker, etc.
If you’re new to FMCSA registration, you’ll also be enrolled in the New Entrant Safety Assurance Program, which includes:
- A mandatory safety audit within the first 12 months
- Recordkeeping checks (maintenance, driver logs, etc.)
- Compliance with FMCSA safety standards
