Vehicle marking/Identification - District of Columbia

Intrastate

The District of Columbia has adopted §390.21 of the Federal Regulations.

Vehicles meeting the following definition of a commercial motor vehicle (CMV) operating solely within the District must comply by displaying the legal company name and US DOT number on both sides of the vehicle:

Interstate

All commercial motor carriers (for-hire and private) operating interstate are subject to the marking requirements of 49 CFR 390.21 which requires all CMVs to display, on both sides of the power unit, the US DOT number and the legal name of the business entity that owns or controls the motor carrier operation, or the “doing business as” (DBA) name, as it appears on the Form MCS-150.

Any new or used commercial vehicles added to a motor carrier’s fleet must be identified with the US DOT number and single trade name before being put into service.

The regulations do not require the city, state, or MC number to be displayed on the vehicle.
