FAQ

Frequently asked questions

What is the FMCSA Drug and Alcohol Clearinghouse?

An online database maintained by the FMCSA that tracks CDL holders' drug and alcohol program violations. It helps employers, state licensing agencies, and enforcement officials ensure compliance with FMCSA testing regulations.

Who is required to register in the Clearinghouse?

All employers of CDL drivers, CDL drivers themselves, Consortia/Third-Party Administrators (C/TPAs), and Medical Review Officers (MROs) are required to register.

What types of violations are recorded in the Clearinghouse?

Positive drug or alcohol tests, refusals to test, actual knowledge violations, and return-to-duty completion information are all recorded.

How does the Clearinghouse benefit employers?

It allows employers to quickly verify whether a driver has unresolved drug or alcohol violations before hiring, and helps maintain ongoing compliance through annual queries.

What is the cost to use the Clearinghouse?

Registration is free. However, full queries (which reveal violation details) cost $1.25 per query. Limited queries for pre-employment are free of charge.

How long is information retained in the Clearinghouse?

Violation records are retained for five years, or until the driver completes the return-to-duty process — whichever is later.

What penalties exist for non-compliance?

Employers who fail to query the Clearinghouse or report violations may face civil penalties of up to $16,000 per violation under FMCSA regulations.

How often must employers query the Clearinghouse?

Employers must conduct a full query before a CDL driver's first day in a safety-sensitive position, and at least once every 12 months for all current CDL employees.

What is the return-to-duty process?

Drivers with violations must complete a substance abuse professional (SAP) evaluation, follow the prescribed treatment, pass a return-to-duty test, and complete follow-up testing before resuming safety-sensitive functions.

What should an employer do if they discover a driver violation?

The driver must be immediately removed from safety-sensitive functions. The employer must then follow the FMCSA's return-to-duty process before the driver can resume operations.
