Important Laws and Regulations in Arizona

FMCSA Testing Rules: The Federal Motor Carrier Safety Administration (FMCSA) mandates that all commercial drivers are subject to drug and alcohol testing as outlined in 49 CFR Part 382.
“Prohibited” Clearinghouse Status: A violation results in a “prohibited” status in the FMCSA Clearinghouse. This status prevents you from legally operating a commercial vehicle for any DOT-regulated employer in the U.S.
Employer Reporting Duties: Employers are required to report all violations to the Clearinghouse and cannot permit a driver to perform safety-sensitive work until the SAP process is fully documented as complete.

Strict BAC for Commercial Drivers: Arizona enforces a strict Blood Alcohol Concentration (BAC) limit of 0.04% for CDL drivers, half the 0.08% limit for other drivers. A DUI conviction in a commercial vehicle results in a one-year CDL disqualification for a first offense.
Zero Tolerance (“Not a Drop”): Arizona has a “not a drop” law. If a commercial driver has any detectable amount of alcohol in their system (below 0.04%), they will be placed out-of-service for 24 hours.
CDL Disqualification: Under Arizona law, a first conviction for a major offense like a DUI (in any vehicle), leaving the scene of an accident, or using a vehicle in the commission of a felony will result in a one-year CDL disqualification. A second major offense results in a lifetime disqualification.
