Coming Soon
Commercial Driver’s License Drug and Alcohol Clearinghouse
The Clearinghouse will improve highway safety by helping employers, FMCSA, State Driver Licensing Agencies, and State law enforcement to quickly and efficiently identify drivers who are not legally permitted to operate commercial motor vehicles (CMVs) due to drug and alcohol program violations. This secure online database will provide access to real-time information, ensuring that drivers committing these violations complete the necessary steps before getting back behind the wheel, or performing any other safety-sensitive function.
