The Federal Motor Carrier Safety Administration (FMCSA) enforces regulations to maintain a drug and alcohol-free environment among commercial motor vehicle (CMV) drivers, thereby enhancing safety on U.S. roadways. These regulations apply to all individuals and entities operating CMVs requiring a commercial driver’s license (CDL) in interstate or intrastate commerce. fmcsa.dot.gov+1fmcsa.dot.gov+1

FMCSA Drug & Alcohol Clearinghouse
The Drug & Alcohol Clearinghouse is an online database providing real-time access to information about CDL drivers’ drug and alcohol program violations. Employers are required to query the Clearinghouse before hiring drivers and annually for current employees to ensure compliance. fmcsa.dot.gov+2clearinghouse.fmcsa.dot.gov+2fmcsa.dot.gov+2the-sun.com+1the-sun.com+1
Consequences of Non-Compliance
Drivers with violations recorded in the Clearinghouse face a “prohibited” status, rendering them ineligible to operate a CMV until completing the return-to-duty process. As of November 18, 2024, state driver licensing agencies are mandated to downgrade the CDL privileges of drivers with a “prohibited” status, effectively suspending their commercial driving rights. fmcsa.dot.gov+4the-sun.com+4the-sun.com+4
