What is a USDOT Number?
Companies that operate commercial vehicles transporting passengers or hauling cargo in interstate commerce must be registered with the FMCSA and must have a USDOT Number. Also, commercial intrastate hazardous materials carriers who haul types and quantities requiring a safety permit must register for a USDOT Number.
The USDOT Number serves as a unique identifier when collecting and monitoring a company's safety information acquired during audits, compliance reviews, crash investigations, and inspections. Click the button below to access our interactive tool that will determine if you need a US DOT number:

You are required by FMCSA to obtain a USDOT Number and comply with the Federal Regulations.
It is the responsibility of motor carrier operators and drivers to know and comply with all applicable Federal Motor Carrier Safety Regulations. Safety compliance and safe operations translate into saved lives and protected property. We believe the information in this package, when effectively applied, will contribute to safer motor carrier operations and highways.
Apart from federal regulations, some states require their intrastate commercial motor vehicle registrants to obtain a USDOT Number. These states include:
