FMCSA Clearinghouse and Alcohol Violations: What Employers Must Report

When a driver blows a 0.04 or higher on a DOT breath alcohol confirmation test, the paperwork does not end with the testing form and a call to the Designated Employer Representative. For CDL drivers, the employer also has a reporting duty to the FMCSA Drug and Alcohol Clearinghouse, and a missed deadline is a compliance problem of its own. Fleets that already run a clean 49 CFR Part 40 process often stumble on this second layer, because it lives in 49 CFR Part 382 and in a separate online system.

What alcohol violations must an employer report to the Clearinghouse?

Employers must report two alcohol-related events for CDL and CLP holders: an alcohol confirmation test result of 0.04 or higher, and a refusal to submit to a DOT alcohol test. FMCSA's Clearinghouse pages set the deadline at the close of the third business day after the employer obtains the information. A result between 0.02 and 0.039 is not a reportable violation. That result still removes the driver from safety-sensitive duty for the period Part 40 requires, but it does not create a Clearinghouse record. The reporting duty attaches to the employer that gave the test. The Clearinghouse record is also separate from the paperwork you already keep on the alcohol testing form, so a completed form does not satisfy the report. Treat the report as its own line item on the post-test checklist, with a named owner and a date written next to it.

Who has to file, and how fast?

The employer files, not the BAT and not the collection site. A third-party administrator can file on the employer's behalf if the employer has designated it in the Clearinghouse, but the legal responsibility stays with the employer. The clock starts when the employer learns of the violation, not when the test happened, and it runs in business days. In practice the safest habit is to file the same day the DER receives the confirmation result. The record then shows the driver as prohibited from performing safety-sensitive functions, and any employer that queries the driver afterward will see it.

What happens to the driver after a report?

Once the violation is recorded, the driver's Clearinghouse status becomes prohibited. No DOT-regulated employer may allow that driver to perform safety-sensitive work until the return-to-duty process under 49 CFR Part 40, Subpart O is complete and the status changes to not prohibited. FMCSA also notifies the driver's State Driver Licensing Agency, and the agency must start the process of removing commercial driving privileges from the license within 60 days. That is a CDL downgrade, and reinstatement follows completion of return-to-duty. So the consequence reaches past the current employer: a driver cannot simply take a job at the next carrier down the road, because pre-employment queries will surface the prohibited status. For the full sequence of SAP evaluation, education or treatment, and follow-up testing, see our guide to return to duty after an alcohol violation.

Reporting duties by event

Event	Reportable to Clearinghouse?	Employer action
Confirmation test below 0.02	No	None beyond normal records
Confirmation test 0.02 to 0.039	No	Remove from safety-sensitive duty per Part 40
Confirmation test 0.04 or higher	Yes	Remove from duty, report by third business day, refer to SAP
Refusal to test	Yes	Same as a 0.04 result, see what counts as a refusal

What queries must employers run?

Reporting is half the system. Employers must query the Clearinghouse for a prospective driver before allowing that person to operate a commercial vehicle, and must query each current driver at least once a year. A pre-employment query requires the driver's consent in the Clearinghouse. A negative query result is what lets a hire proceed, and a result showing a 0.04 confirmation test or a refusal blocks safety-sensitive work until return-to-duty is finished. Many small fleets meet the annual query by putting every driver on a single calendar date, then checking that each one is logged. A driver's record can change between queries, which is why the annual query is a floor and not a substitute for keeping your own testing records current.

How Foster handles the handoff from test to report

Our BAT technicians run the test, complete the alcohol testing form, and hand the confirmation result to the client's DER on the spot. We do not file to the Clearinghouse for clients, because that duty and the removal decision belong to the employer. What we do is make the DER's job easy: the result, the time of the confirmation test, and the form copy reach the DER the same day, so the three business day clock is not spent waiting on paperwork. Clients who train their own technicians through our BAT training course get the same handoff checklist, and employers building a program from scratch can start with a quote request or read about what a DER actually does.

Frequently asked questions

Does a 0.03 result go into the Clearinghouse?

No. Only confirmation results of 0.04 or higher and refusals are reportable. A 0.03 still requires removal from safety-sensitive duty under Part 40.

Can a driver see their own Clearinghouse record?

Yes. Drivers can register and view their own record, and can respond when an employer requests consent for a query.

Do non-CDL safety-sensitive employees go in the Clearinghouse?

No. The Clearinghouse covers CDL and CLP holders under FMCSA rules. Other DOT modes have their own Part 40 process.

Who reports if a third-party administrator runs our program?

The administrator can submit the report if the employer has assigned it that role in the Clearinghouse, but the employer stays responsible for accuracy and timing.
