FMCSA Clearinghouse: A Driver's Guide

Short answer: The FMCSA Clearinghouse is a federal database of CDL driver drug and alcohol program violations. Every CDL holder must be registered, every employer must query it before hiring and at least once per year, and every violation stays on your record until you complete the SAP-led return-to-duty process.

What is the FMCSA Clearinghouse?

The Drug and Alcohol Clearinghouse is an online database run by the Federal Motor Carrier Safety Administration (FMCSA). It tracks drug and alcohol program violations for anyone who holds a commercial driver's license (CDL or CLP) and operates a commercial motor vehicle subject to DOT testing rules. It went live January 6, 2020, and full "Clearinghouse-II" downgrade enforcement — where states must downgrade a CDL when a driver has a "prohibited" status — is now in effect.

Who has to register?

• CDL drivers — required to register before you can respond to a query, view your own record, or complete return-to-duty steps.
• Employers / motor carriers — including owner-operators with their own DOT authority. Owner-operators must designate a Consortium/Third-Party Administrator (C/TPA) to handle queries and reporting on their behalf.
• Medical Review Officers (MROs) and Substance Abuse Professionals (SAPs) — report violations and RTD progress.

How to register as a driver (step by step)

1. Go to clearinghouse.fmcsa.dot.gov and click "Register."
2. Create a Login.gov account (or use an existing one). This is the federal sign-in system — it's separate from the Clearinghouse itself.
3. Select "CDL Driver" as your user role.
4. Enter your CDL number, state of issuance, and date of birth — they must match your CDL exactly.
5. Verify your identity and finish the profile.

There is no fee for drivers to register or to view their own record.

Queries: pre-employment, annual, and limited vs full

Employers must run a query before hiring a CDL driver and at least once per year for every driver they employ. There are two types:

• Full query: Required for pre-employment. Shows detailed violation information. Requires specific electronic consent from the driver in the Clearinghouse before the employer can see the results.
• Limited query: Used for the annual check. Tells the employer only whether any information exists about you. Requires general written consent from the driver (kept on file by the employer) — not entered in the Clearinghouse. If a limited query comes back showing information exists, the employer has 24 hours to get full-query consent and run a full query.

Annual queries are one piece of the larger DOT random drug testing pool requirement. Every driver in a safety-sensitive role must also be in a random selection pool for unannounced testing.

What counts as a violation?

• A verified positive DOT drug test
• An alcohol test of 0.04 BAC or higher
• Refusing a test (including failure to appear, leaving the site, or adulterating a sample)
• Actual knowledge of on-duty drug or alcohol use by a supervisor

Once reported, a violation puts you in "prohibited" status — you cannot perform safety-sensitive functions (including driving a CMV) until you complete return-to-duty.

Clearinghouse-II: the CDL downgrade

Under the Clearinghouse-II rule, State Driver Licensing Agencies must query the Clearinghouse before issuing, renewing, transferring, or upgrading a CDL — and they must downgrade the CDL of any driver in "prohibited" status. In practice: if you're flagged in the Clearinghouse and haven't started the RTD process, your state can pull your commercial driving privileges. A downgraded CDL becomes a regular driver's license until the RTD process is complete and your status returns to "not prohibited."

How long does a violation stay on my record?

A minimum of five years, or until you complete the entire return-to-duty process (SAP evaluation, education/treatment, observed RTD test, and the follow-up testing plan) — whichever is longer. The record itself stays visible in the Clearinghouse for that full five-year window even after RTD is complete; what changes is your status from "prohibited" to "not prohibited."

How to check your own Clearinghouse record

Log in at clearinghouse.fmcsa.dot.gov, go to "My Dashboard," and click "View My Record." You can do this anytime, for free. It's a smart habit before any job application — and immediately after any test — so there are no surprises.

Owner-operators: special rules

If you operate under your own DOT authority, you are both the driver and the employer for Clearinghouse purposes. FMCSA requires you to designate a C/TPA (Consortium/Third-Party Administrator) to handle queries and reporting on your behalf — you cannot query yourself. Joining a consortium covers this requirement along with your random pool participation. Our pricing is straightforward: owner-operators pay $150/year plus drug tests, and small fleets pay $200/year plus drug tests.

Disputing incorrect information

If something on your record is wrong — wrong driver, clerical error, identity mix-up — you can file a petition through the Clearinghouse to have it reviewed. FMCSA does not remove correctly-reported violations; the only path forward for a real violation is return-to-duty.

Common mistakes drivers make

• Not registering until they need to. If a carrier needs full-query consent and you're not registered, the hire stalls. Register now.
• Ignoring the annual limited-query notice. If you decline consent, you're out of compliance and can't drive.
• Assuming a state legalization means it's okay. DOT does not recognize state medical or recreational marijuana. A positive is a positive.
• Trying to "wait it out." Violations don't expire on their own — you must complete RTD or live with a downgraded CDL and a prohibited status.

Bottom line

The Clearinghouse is the single most important compliance system in your CDL career. Register today, check your record before every job change, give the right consent at the right time, and if a violation ever shows up, start the SAP process immediately — that's the only way back to "not prohibited."
