What is 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." - FMCSA

Who should have a USDOT Number?
"Companies that operate commercial vehicles transporting passengers or hauling cargo in interstate commerce must be registered with the FMCSA [Federal Motor Carrier Safety Administration] 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." - FMCSA

Some USDOT Requirements

  • Decal includes company name or operator name (company logo with name).

  • Decal includes “US DOT” followed by the assigned number (typically, 8 digits).

  • State abbreviation follows the number (if required).

  • Font is legible from 50 feet (ca. 15 m) away during daylight hours (minimum height of 2in”).

  • Color of decal contrasts with background color (try to avoid foil or chrome colors as primary colors).
