Vehicle marking/Identification - Delaware

Intrastate

All vehicles and vehicle combinations with a GRW of 26,001 pounds or more must comply with the US DOT marking requirements in §390.21 and display the DOT number and legal company name.

Vehicles 26,000 pounds or less GRW are not required to comply, unless the vehicle is used to transport hazardous materials of a type or quality that requires marking or placarding.

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.
