The Federal Motor Carrier Safety Administration (FMCSA) plays a crucial role in ensuring the safety of our nation's roadways, particularly when it comes to regulating commercial motor vehicle (CMV) drivers. A significant step in this effort was the establishment of the Drug and Alcohol Clearinghouse (Clearinghouse), which tracks CMV drivers who are prohibited from operating due to drug or alcohol violations. As of November 18, 2024, a new regulation under the Clearinghouse-II final rule will take effect, creating significant changes for drivers with commercial driver’s licenses (CDLs) or commercial learner’s permits (CLPs).
