Drug and Alcohol Clearing House
Drug and Alcohol Clearing House:
January 6, 2020 is the mandatory effective date for the use of the Clearinghouse
mandated by Congress to report and query information about driver drug and alcohol
program violations. Employers must conduct both electronic queries within the
Clearinghouse and manual inquiries with previous employers to cover the preceding three
years. 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. Get News and Updates about the Clearinghouse by
