USDOT Number: What It Is & How to Stay Compliant
What Is a USDOT Number?
A USDOT number is a unique identifier issued by the Federal Motor Carrier Safety Administration (FMCSA) that allows regulators to track a commercial carrier’s safety records, compliance, and regulatory requirements. It is required for most commercial motor vehicles (CMVs) that operate in interstate commerce and serves as a crucial tool in enforcing DOT regulations.
The FMCSA uses USDOT numbers to monitor:
✔ Safety records (violations, crashes, and compliance issues)
✔ Fleet inspections and audits
✔ Compliance with FMCSA regulations
✔ Driver qualifications and medical certifications
Why Does the USDOT Number Matter?
Without a USDOT number, a company cannot legally operate in most cases. Non-compliance can result in penalties, fines, and even a business shutdown. To avoid violations, companies must maintain up-to-date records, renew their USDOT numbers, and follow all FMCSA rules.

Who Needs a USDOT Number?
According to FMCSA regulations, you need a USDOT number if your business:
✔ Operates CMVs across state lines (interstate commerce)
✔ Transports hazardous materials that require a safety permit
✔ Owns or manages CMVs with a GVWR of 10,001 lbs or more
✔ Carries more than 8 passengers for compensation or more than 15 passengers without compensation
If your company meets any of these criteria, you must register for a USDOT number to remain compliant.
