FMCSA Clearinghouse
Also known as: Drug & Alcohol Clearinghouse
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
Definition
The FMCSA Drug & Alcohol Clearinghouse is the federal database that tracks every drug and alcohol program violation by a CDL driver since January 2020. Carriers must query the Clearinghouse before hiring (full query) and annually thereafter (limited query) under 49 CFR §382.701. Drivers must register and consent to each query. Positive results, refusals to test, and return-to-duty actions are all reported. A driver with an unresolved Clearinghouse violation is prohibited from performing safety-sensitive functions. The Clearinghouse is the single source of truth for DOT drug program violations; pre-2020 violations remain with the prior employer's records.
