Starting April 27, 2026, the FMCSA Drug and Alcohol Clearinghouse added a stronger identity verification step for certain new accounts, part of a broader push to close loopholes in how positive drug and alcohol results move through the system. Here is what changed and what it means for your safety file.
What is the FMCSA Drug and Alcohol Clearinghouse
The Clearinghouse is a national database FMCSA (Federal Motor Carrier Safety Administration) runs to track drug and alcohol violations for commercial drivers. Employers, medical review officers (MROs), and substance abuse professionals (SAPs) use it to check a driver's status before letting them get behind the wheel, and to report violations when they happen.
What changed under the FMCSA Drug and Alcohol Clearinghouse 2026 rules
As of April 27, 2026, new registrations for certain Clearinghouse user roles, including employers registering without a portal account, consortium and third-party administrators, MROs, and SAPs, must complete an identity verification step. The process uses a mobile app to scan a government-issued ID and take a photo, and the system locks the verified name so it cannot be edited afterward. FMCSA says this closes a gap that let bad actors set up fraudulent accounts.
Alongside this change, FMCSA and state agencies have also been tightening how quickly positive results move through the system and how states act on a driver's prohibited status when handling a CDL (commercial driver's license) application, renewal, or upgrade. The exact timelines can vary by state and by the type of violation, so check with your state licensing agency or your compliance provider for the specifics that apply to your situation.
Why this matters to owner-operators and small fleets
If you are an owner-operator, you are both the employer and the driver in the eyes of the Clearinghouse, which means you still have to run your own query, not just wait for someone else to catch a problem. If you run a small fleet, missing a required query, or letting a driver's account sit unverified, can leave a violation unnoticed until a roadside inspection or an audit finds it. A driver in prohibited status who keeps driving without completing the return-to-duty process puts your whole operation at legal risk, not just that one driver.
How to stay compliant, step by step
- Register for a Clearinghouse account if you do not already have one, and complete the identity verification step if your role requires it.
- Run a pre-employment query for every new driver before they get behind the wheel.
- Run an annual query for every current driver, at least once every 12 months.
- Report any positive test, refusal, or return-to-duty completion for your own drivers as required.
- Keep records of every query and report in your compliance file in case of an audit.
Mistakes to avoid
A common mistake is assuming a one-time query at hiring is enough. The annual query is separate and required for every active driver, not just new hires. Another mistake is letting an MRO, SAP, or third-party administrator account sit unverified, which can block reporting right when you need it. Owner-operators sometimes also forget that, because they wear both hats, they still need to complete the driver side of registration, not just the employer side.
When to call TCZ Permits
Staying current with Clearinghouse queries and identity verification is one more compliance task on top of running your business. TCZ Permits helps carriers keep their compliance file organized alongside their authority filings, so nothing gets missed when an audit comes.

Common questions
Do owner-operators need a Clearinghouse account if they drive their own truck? Yes. As both the employer and the driver, an owner-operator needs to complete both sides of registration and run the required queries.
How often do I need to query the Clearinghouse for my drivers? At least once every 12 months for each current driver, plus a pre-employment query before hiring anyone new.
What happens if a driver is in prohibited status? They cannot legally operate a commercial vehicle until they complete the full return-to-duty process, and their CDL can be affected until that process is finished.
