What does the FMCSA Drug and Alcohol Clearinghouse require?

"The Clearinghouse requires every employer of CDL and CLP drivers subject to Part 382 testing to register", run a full query before a driver performs a safety-sensitive function, query at least once a year for every current driver, and report violations by the close of the third business day. "A driver whose record shows an unresolved violation is prohibited from safety-sensitive functions until the driver completes the SAP evaluation, referral and education or treatment process and passes a return-to-duty test." In the "Prohibited status" section, add: "A driver who has completed the SAP process and a negative return-to-duty test but not the whole follow-up testing plan may return, provided the employer takes on responsibility for managing the remaining follow-up tests (382.701(d)(2))."

What the Clearinghouse is, and who has to register

FMCSA describes the Clearinghouse as a secure online database that gives employers, FMCSA, State Driver Licensing Agencies and State law enforcement real-time information about CDL and CLP holders' drug and alcohol program violations. It holds violations of the prohibitions in 49 CFR Part 382 Subpart B — verified positive tests, test refusals, employer reports of actual knowledge — and it holds the resolution side too: the SAP's report of a completed return-to-duty process, the negative return-to-duty test, and completion of follow-up testing. The compliance date for the final rule was January 6, 2020, so that is where the record starts.

Registration is not optional. Each employer and service agent must register before accessing or reporting information (49 CFR 382.711(a)). Registration is valid for five years, and FMCSA cancels it for anyone who has not queried or reported in two years (382.713(a) and (b)). Employers must verify annually the names of the people they authorize to use the Clearinghouse, and update any change to a designated C/TPA within 10 days (382.711(b)(2) and (b)(3)).

Employers must retain for three years a record of each query and all information received in response. As of January 6, 2023, an employer who maintains a valid registration fulfills that requirement (382.701(e)).

Full query versus limited query

A full query releases the information in a driver's Clearinghouse record to the employer and requires the driver's specific consent (49 CFR 382.701(a)(2)). A limited query tells the employer only whether there is information about that driver in the Clearinghouse, and does not release the information (382.701(b)(2)). The two are not interchangeable.

A limited query that comes back with records found is not a result you can act on. It is a trigger.

Full query. Returns the violation detail. Requires the driver's specific electronic consent inside the Clearinghouse, for each query. This is the only query type that satisfies the pre-employment requirement.
Limited query. Returns only whether a record exists. Runs on a general consent the employer obtains outside the Clearinghouse. The regulation authorizes it only in lieu of a full query to satisfy the annual requirement.
Records found on a limited query. The employer must conduct a full query within 24 hours.

The pre-employment query

Employers must not employ a driver subject to Part 382 testing to perform a safety-sensitive function without first conducting a pre-employment query (49 CFR 382.701(a)(1)), and that query must be a full query (382.701(a)(2)). It looks for a verified positive, adulterated or substituted controlled substances test result; an alcohol confirmation test at 0.04 or higher; a refusal to submit to a test in violation of 382.211; and an employer's report of actual knowledge of prohibited alcohol or controlled substance use.

The driver has to be registered in the Clearinghouse to give the electronic consent a full query needs. FMCSA is explicit that drivers are not required to register in general, but registration is required to provide that consent, and that includes all pre-employment queries. Handle it in the application packet, not on the driver's start date.

Since January 6, 2023, the Clearinghouse query is how employers satisfy the three-year previous-employer drug and alcohol inquiry in 49 CFR 391.23(e) with respect to FMCSA-regulated employers (391.23(e)(4)). Two items still have to be chased by hand. If the applicant is subject to follow-up testing and has not completed it, request the follow-up testing plan directly from the previous employer under 49 CFR 40.25(b)(5). If the applicant was tested under a DOT mode other than FMCSA, request that history from those employers directly.

The annual query, and the 24-hour rule

Employers must query the Clearinghouse at least once per year for all employees subject to Part 382 testing (49 CFR 382.701(b)(1)). A limited query satisfies it, with the driver's consent, and that consent may be effective for more than one year (382.701(b)(2)).

Body: "The Clearinghouse tracks the requirement on a rolling 365-day basis from the date of the employer's last query. FMCSA also permits an employer to use another 12-month period it determines, provided 49 CFR 382.701(b) is still met — nothing in the rule dictates the time of year, so a common annual date for the whole roster is allowed. Whichever you pick, the clock for each driver runs from that driver's last query." FAQ #2: "49 CFR 382.701(b)(1) requires a query at least once per year for every employee subject to Part 382 testing. The Clearinghouse tracks it on a rolling 365-day basis from the employer's last query, but FMCSA lets an employer use another 12-month period it determines instead, so a common annual date for the roster is permitted." FMCSA also treats a follow-on query as satisfying the annual requirement and resetting the twelve months from its own date.

If the limited query shows that information exists, the full query is due within 24 hours. Miss that window and the driver must come off every safety-sensitive function until the employer conducts the full query and the results confirm the record contains no prohibitions (382.701(b)(3)).

FMCSA will notify the employer if information is entered about a driver during the 30-day period immediately following that employer's query (382.701(c)). Separately, FMCSA states that since March 8, 2023 it emails employers when a driver they have queried has new information recorded within 12 months of a pre-employment or annual query.

Consent: two different things with the same name

This is where carriers get written up. There are two consents, they are obtained in different places, and one does not substitute for the other.

If the driver refuses either consent, the employer may not permit that driver to perform a safety-sensitive function (49 CFR 382.703(c)). FMCSA publishes a sample limited consent form but does not require employers to use its format.

General consent, outside the Clearinghouse. Required before any query, including a limited one. Written or electronic. FMCSA requires the limited consent request to specify the timeframe the driver is consenting to. The employer must retain the consent for three years from the date of the last query (382.703(a)).
Specific electronic consent, inside the Clearinghouse. Required before the employer may access the information in the driver's record, which means before any full query, including every pre-employment query (382.703(b) and (d)).

What employers must report, and how fast

Employers must report the following to the Clearinghouse by the close of the third business day following the date on which they obtained the information (49 CFR 382.705(b)(1)):

Violations the employer learns of through actual knowledge carry the same deadline, counted from the day the employer obtains that knowledge (382.705(b)(4)). Actual knowledge has a narrow definition: the employer's direct observation of use, information from a previous employer, a traffic citation for driving a CMV while under the influence, or the employee's admission (382.107). Direct observation means observing the use itself, and does not include behavior or physical characteristics that would warrant a reasonable suspicion test.

MROs report verified positives and their own refusal-to-test determinations within two business days (382.705(a)(1)). "An employer may designate a C/TPA to carry out its reporting duties, and the employer retains ultimate responsibility for compliance (382.705(c)). A C/TPA's authority to query as well as report comes from the employer's registration, which must identify the C/TPA and authorize it (382.711(b)(3)). An employer who employs himself or herself as a driver must designate a C/TPA for his or her own reporting (382.705(b)(6)) — and in that one case the employer does not retain the responsibility, by the exception in 382.705(c)." Information received from a query may be used only to determine whether a prohibition applies to that driver (382.723(b)).

An alcohol confirmation test result with an alcohol concentration of 0.04 or greater.
A negative return-to-duty test result.
A refusal to take an alcohol test under 49 CFR 40.261.
A refusal-to-test determination under 49 CFR 40.191(a)(1) through (4), (a)(6), (a)(8) through (11), or (d)(1).
A report that the driver has successfully completed all follow-up tests prescribed in the SAP report.

Prohibited status, return to duty, and the CDL downgrade

"...and no employer may allow that driver to perform them (49 CFR 382.701(d) and 382.501(a) and (b))."

The way back is 49 CFR Part 40 Subpart O. The first step is an evaluation by a substance abuse professional; until the driver completes the SAP evaluation, referral and education or treatment process, the driver cannot perform DOT safety-sensitive duties for any employer (40.285(a)). The return-to-duty test comes only after the SAP determines the driver has successfully complied, and "the driver needs a negative drug result and/or an alcohol concentration below 0.02 — whichever the SAP prescribed — before resuming (40.305(a))". The SAP then writes a follow-up testing plan of at least six unannounced tests in the first 12 months of safety-sensitive duty after the return, and may require tests during the following 48 months (40.307(d)). That plan follows the driver to subsequent employers (40.307(e)). "An employer is not required to offer the return-to-duty route at all (40.289(a)). If it does, it must ensure the driver gets a SAP evaluation meeting 40.281 and successfully complies with the SAP's recommendations before performing the duty again (40.289(b))."

Since November 18, 2024, prohibited status also reaches the license. On notification that a driver is prohibited, the State must initiate its downgrade procedure, and the downgrade must be completed and recorded on the CDLIS driver record within 60 days (49 CFR 383.73(q)). The driver may not drive a CMV until the State Driver Licensing Agency reinstates the CLP or CDL privilege (382.503(b)).

The violation stops appearing to querying employers only when all four conditions in 382.719(a) are met: the SAP report is in, the employer reports the negative return-to-duty test, the current employer reports the follow-up tests complete, and five years have passed since the date of the violation determination.

Most carriers fail this on the calendar rather than on the rule. The annual query date moves per driver, the limited consent has to be on file and still inside the timeframe it names, and the three-business-day reporting clock starts the day somebody in the office learns something. Fleetmule connects to the FMCSA Drug & Alcohol Clearinghouse alongside FMCSA and PSP, and "Fleetmule connects to the FMCSA Drug & Alcohol Clearinghouse alongside FMCSA and PSP, collects consent and screening records, and keeps results with the driver's file.".

Common questions

Does a pre-employment Clearinghouse query have to be a full query?

Yes. 49 CFR 382.701(a)(2) requires a full query, which releases the information in the driver's record and requires the driver's specific electronic consent in the Clearinghouse. A limited query is authorized only in lieu of a full query to satisfy the annual requirement.

How often is the annual Clearinghouse query actually due?

49 CFR 382.701(b)(1) requires a query at least once per year for every employee subject to Part 382 testing. FMCSA tracks it on a rolling 365-day basis from the date of the employer's last query, so the due date is different for each driver.

What happens if a limited query shows that records exist?

The employer must conduct a full query within 24 hours of the limited query. If it does not, the driver must not continue to perform any safety-sensitive function until the full query is conducted and the results confirm the record contains no prohibitions (49 CFR 382.701(b)(3)).

How long does an employer have to report a violation to the Clearinghouse?

Until the close of the third business day following the date the employer obtained the information (49 CFR 382.705(b)(1)). The same deadline applies to violations learned through actual knowledge, counted from the day the employer obtains that knowledge (382.705(b)(4)).

Can a driver keep a CDL while in prohibited status?

"Not for long, unless the driver clears the status first. Beginning November 18, 2024, 49 CFR 383.73(q) requires the State to initiate a downgrade on notification that the driver is prohibited, and to complete and record it on the CDLIS driver record within 60 days. If the State is notified the driver is no longer prohibited before the downgrade is recorded, it must terminate the downgrade process where State law allows (383.73(q)(1)). Once the privilege is removed, the driver may not drive a CMV until the State Driver Licensing Agency reinstates it (382.503(b))." The driver may not drive a CMV until the State Driver Licensing Agency reinstates the privilege (382.503(b)).
