What is a USDOT Number?

US companies operating commercial vehicles to transport passengers or haul cargo in interstate commerce need to be registered with the Federal Motor Carrier Safety Administration (FMCSA) and must have a USDOT identifier. Similarly, commercial intrastate carriers who transport certain types and certain quantities of hazardous materials that require a safety permit must register for a USDOT Number.

USDOT number serves as a unique identifier to check a company's safety information during audits, compliance reviews, road accidents and inspections.

DOT number recognition

CARMEN® DOT offers automatic recognition of USDOT numbers on commercial vehicles with the highest accuracy and recognition rates in the industry.

The image source can either be analog, digital or IP cameras – CARMEN® DOT accepts still images or MJPEG video streams as well. By adding illumination to the cameras, the software is able to adapt to the environmental changes for a smooth 24/7 operation. It is fast, easy and straightforward to use.

Arriving in a form of an SDK, its development libraries (DLL, SO) allow flexible integration on both Windows and Linux platforms. In server mode CARMEN® DOT is able to perform parallel processing and handling of unlimited camera inputs.
