The FMCSA Drug & Alcohol Clearinghouse is a federal database tracking commercial driver's license (CDL) holders who have positive drug or alcohol tests, refused to test, or are working through return-to-duty. It launched in January 2020 to close a long-standing gap: drivers who tested positive at one employer could disappear, move to another carrier, and never disclose the failure.
The Clearinghouse fixes that gap by requiring two things from every employer of CDL drivers: (1) run a query before letting any new driver perform a safety-sensitive function, and again at least annually for every existing driver, and (2) report any driver who has a positive test, refused to test, or completed return-to-duty.
The first thing — the queries — is where 95% of small fleets trip up. And the rules changed substantively on November 18, 2024, when the FMCSA's “Clearinghouse-II” rule made the previously-limited annual query into a full query by default.
◇ What changed
The FMCSA's “Clearinghouse-II” rule replaced the limited annual query with a full annual query by default. Every existing driver now needs a full query — with explicit electronic consent — at least once every 12 months.
Here's what you actually need to do, in the order you need to do it.
Who must register.
Five roles, separate accounts. Owner-operators register twice.
Per 49 CFR § 382.703, the following parties must register with the Clearinghouse before they can interact with it:
Employer
Every motor carrier with CDL drivers
Registration is per legal entity. Even a one-truck owner-operator registers in this role.
Driver
Every CDL holder operating a CMV
A driver registration is separate from the employer registration — different account, different login.
C/TPA
Consortia / third-party administrators
Most small fleets outsource Clearinghouse mechanics to a C/TPA. The C/TPA registers itself, then registers as an agent for the carrier.
MRO
Medical Review Officers
MROs report verified positive tests directly to the Clearinghouse and notify the employer.
SAP
Substance Abuse Professionals
SAPs administer return-to-duty and report driver progress; required registration for any practitioner working DOT RTD cases.
If you're a one-truck owner-operator, you are both the employer and the driver, and you must register in both roles, separately. This is the most-missed step for owner-operators.
The pre-employment full query.
No driver in a safety-sensitive seat until this query clears.
49 CFR § 382.701(a) requires that before any driver performs a safety-sensitive function for the first time, the employer must request and receive a full query of the Clearinghouse.
A full query is the only kind of query that returns complete information about the driver — every positive test, refusal, and return-to-duty record. Limited queries (see Section III) only tell you whether there's information; they don't tell you what.
To run a full query, you need:
The driver's written specific consent, captured outside the Clearinghouse system (a paper or e-signed form), and
The driver's separate electronic consent inside the Clearinghouse portal, where the driver acknowledges the request before the FMCSA releases the records.
A pre-employment full query is not an “if the driver consents” event — you cannot hire the driver without the query result. The driver must consent. If the driver refuses the consent step, you treat it as a positive result and you do not put them in a safety-sensitive function. This is one of the trickiest practical points for new employers.
The annual query.
Formerly limited. Now full. The default changed on November 18, 2024.
Before November 18, 2024, the annual query under § 382.701(b) was a limited query — a request that returned only whether or not information existed in the Clearinghouse about the driver. If information existed, the employer had a 24-hour window to obtain electronic consent from the driver and convert the limited query into a full query to actually see the records.
This created an obvious workaround: if a driver delayed or refused the consent, the employer might never see the underlying records before the deadline.
The 2024 rule changes the default. As of November 18, 2024, the annual query the FMCSA requires is now a full query. Limited queries still exist for employer-initiated checks outside the annual requirement, but the annual requirement under § 382.701(b) is satisfied only by a full query.
Only after driver consent within 24 hrs
Yes — included in the annual full query
Two-step (limited, then full if hit)
One-step (full query with electronic consent)
Carrier may never see records
No workaround — query is full from the start
Limited cheaper than full
Full-query price applies (~$1.25)
That means every carrier with CDL drivers must now run a full query, with driver consent, at least once every 12 months for every driver they employ. Track the anniversary date for each driver and run the query before the date passes.
Driver consent.
Two consents. Two documents. 99% of carriers track only one.
There are two consent steps involved in a Clearinghouse full query, and they are different documents:
- 01
General consent — captured outside the Clearinghouse system on a written or e-signed form. This is the driver authorizing the carrier to access drug & alcohol testing records as part of employment. It is governed by § 40.25 and is generally part of the DOT application package.
- 02
Specific electronic consent — captured inside the Clearinghouse portal, on a per-query basis. The driver logs into the Clearinghouse, sees a notification (“Carrier X is requesting your records”), and clicks to approve or deny.
The general consent under § 40.25 covers most of the data the employer needs to gather as part of the driver qualification process — DOT testing program participation, MRO information, prior employer history. But it does not, by itself, authorize a full Clearinghouse query. The Clearinghouse requires its own specific consent, captured electronically, every time a full query is run.
This is the failure mode auditors find most often: the carrier has a signed consent form from the driver, but no record of the driver providing electronic consent inside the Clearinghouse portal. The carrier ran the query without the second consent, or worse, didn't run the query at all. Either is a violation.
Query plans & pricing.
Paid by the employer. Bundled in advance. Cheap per query.
Per 49 CFR § 382.711, the FMCSA charges a fee for queries, and employers must purchase a query plan in advance. The plan is essentially a bucket of queries the carrier draws against as they run them.
$1.25 / query
Purchased in bundles. Very small fleets pay per query.
Tiered for larger fleets
Verify current rates at clearinghouse.fmcsa.dot.gov before purchase.
Query plans must be paid for by the employer, not the driver. The carrier purchases enough queries to cover one pre-employment full per new hire plus one annual full per existing driver, with a buffer for any reasonable-suspicion or follow-up queries during the year.
For a five-truck fleet with five drivers (assuming no turnover), the annual Clearinghouse query bill is somewhere between $7 and $15 a year, plus C/TPA administration time. It is not the most expensive item on the compliance ledger — but the violation cost if you skip it is high.
What violations look like.
Five failure modes — each is its own civil-penalty exposure.
Under § 382.717, the FMCSA can assess civil penalties for Clearinghouse violations. The general penalty framework follows the FMCSA's overall civil penalty structure (penalty amounts are inflation-adjusted annually — verify current maxima at ecfr.gov).
Pre-employment
Using a driver in a safety-sensitive function before the pre-employment full query is on file. Each instance is a separate violation. Hits the automatic-failure list in a new-entrant audit.
Annual
Failing to run the annual full query within 12 months of the prior query. Each driver-year that the query is missed is a separate violation.
Reporting
Failing to report a positive test, refusal, or other actionable result under § 382.705. Reporting obligations sit alongside query obligations and are assessed independently.
Removal
Failing to remove a driver from a safety-sensitive function after a positive Clearinghouse result. This is the most serious violation in this framework — exposes the carrier to immediate and significant penalty.
Consent records
Inability to produce electronic consent records for queries run. Auditors look for the consent trail alongside the query result; a query without documented consent is a defect.
In a new entrant audit, missing the pre-employment full query is on the automatic-failure list under § 385.323. Missing the annual query is not automatic-failure but is a serious citation that affects your CSA profile and your audit conclusion.
Operational rhythm.
A five-step monthly cadence for a 1–20 truck fleet.
For a 1–20 truck fleet with CDL drivers, the practical Clearinghouse rhythm is:
01
Once at startup
Register the employer entity and (if you are the driver) register yourself as a driver. Purchase a query plan.
02
For every new hire
Run a pre-employment full query before they perform any safety-sensitive function. File the result and the driver's specific consent record in the DQ file.
03
Annually for every driver
Run a full query at least once every 12 months. Track the anniversary date; most C/TPAs maintain a tickler for this.
04
As needed
Run additional queries when post-accident, reasonable-suspicion, or follow-up testing situations arise.
05
On any positive event
Report the result through the Clearinghouse within the timeframes in § 382.705 — typically by the close of the third business day after the result.
Most small fleets outsource steps 2–5 to a C/TPA — the same entity that runs their consortium random testing pool. The C/TPA charges a per-driver-per-month or per-query fee, handles the query mechanics, and surfaces the results to the carrier with audit-defensible documentation. The Clearinghouse portal is technically free, but the operational burden of running it yourself — especially the consent tracking — is what makes the C/TPA outsource economical for fleets under ~30 drivers.
The Clearinghouse is one database with two failure modes: not running the query when you should have, and not removing the driver when the query said you must. Run the query at hire. Run the query annually. Remove the driver if the result is positive. Everything else is execution detail.
Register once. Query on the right cadence.
We register your business in the Clearinghouse, set up a query plan, run pre-employment and annual full queries on the correct cadence, and surface results audit-defensibly. Especially valuable if you also use our consortium service — one bill, one point of contact.
