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 most small fleets trip up. And since November 18, 2024, the stakes have moved from the office to the license: under FMCSA's “Clearinghouse-II” rule, state licensing agencies now check the same database themselves and downgrade the CDL of any driver in prohibited status.
◇ What changed
FMCSA's “Clearinghouse-II” rule took effect for state licensing agencies. A state must now query the Clearinghouse before issuing, renewing, upgrading, or transferring a CDL, refuse a driver in prohibited status, and downgrade the license of a driver who becomes prohibited. The employer query rules in § 382.701 did not change.
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.
Limited or full — either counts. A limited hit starts a 24-hour clock.
§ 382.701(b) requires a query on every driver at least once a year. It can be a limited query — a request that returns only whether or not information exists about the driver — run under a general consent the driver can give once for more than one year. If information exists, the employer has 24 hours to obtain the driver's electronic consent and run a full query to see the records.
That 24-hour window is where the risk lives. If the driver delays or refuses the electronic consent, the rule is unambiguous: the driver may not perform safety-sensitive functions until the full query is completed — and an employer who keeps them driving in the meantime owns the violation.
A common misreading holds that the November 2024 rule turned the annual query into a full query. It did not — that rule changed what state licensing agencies do, not § 382.701(b). Many carriers and C/TPAs run a full query annually anyway, because it closes the 24-hour exposure and returns the record in one step. Either approach satisfies the rule; the difference is the consent you have to hold.
Only whether a record exists
The record itself — positives, refusals, return-to-duty status
General written consent — may cover more than one year
Specific electronic consent inside the Clearinghouse, per query
Yes — with a full query within 24 hrs if it hits
Yes
No
Yes — the only kind that does

Whichever query you run, the cadence is the same: every driver, at least once every 12 months, with the consent for that query type on file. Track the anniversary date for each driver and run the query before it 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 query per new hire plus one annual query — limited or full — per existing driver, with a buffer for any 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 query within 12 months of the prior one — or, after a limited query hits, failing to run the full query within 24 hours. Each driver-year 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 query at least once every 12 months. A limited query with standing consent counts; if it comes back with a record, run the full query within 24 hours — the driver is off safety-sensitive duty until it clears. 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 full queries and annual 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.
