Vehicle marking/Identification - Arizona

Federal regulations

Arizona has adopted Sec. 390.21 of the Federal Regulations.

Applicability

Section 390.21 applies to a motor vehicle or combination of motor vehicles which has a gross vehicle weight rating (GVWR) of 26,001 pounds or more, and vehicles hauling hazardous materials in an amount required to be placarded.

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 MC number or city/state to be displayed on the vehicle.
