The FMCSA Drug and Alcohol Clearinghouse went live in January 2020, and a surprising number of Utah trucking companies still don't have their processes right. Not because they're careless — but because the Clearinghouse has moving parts that nobody explained clearly when it launched, and the rules around queries have tripped up even experienced fleet managers. This post covers the whole picture: what the Clearinghouse is, who must register, the difference between a full query and a limited query, how violations get reported and what happens next, and where BBB Mobile fits in for Utah operators who want to stay clean on all of it.
The Clearinghouse is a federal database maintained by FMCSA that contains information about CDL holders who have committed drug and alcohol program violations. Before the Clearinghouse existed, a driver who tested positive with one employer could simply move to a new company without that employer ever knowing about the violation. They'd complete a pre-employment drug test, pass it (or try to cheat it), and be back behind the wheel without going through the required Substance Abuse Professional evaluation and return-to-duty process.
That loophole is closed. Now, every time you hire a CDL driver — or move one into a safety-sensitive position — you must run a Clearinghouse query. If that driver has an unresolved violation on their record, the Clearinghouse will flag it. You cannot legally allow them to perform safety-sensitive functions until the violation is resolved.
For Utah trucking companies, this changes the hiring process in a real way. You can't just rely on a driver's verbal assurance that they've never had a positive test. The query is not optional.
Registration requirements break down by role. Here's who needs to be in the system:
Employers — Any motor carrier subject to FMCSA drug and alcohol testing regulations must register with the Clearinghouse. This includes any company operating commercial motor vehicles that require a CDL. If you have CDL drivers, you're an employer for Clearinghouse purposes, and you must register.
Medical Review Officers (MROs) — MROs who review DOT drug test results for FMCSA-regulated employers must be registered and must report verified positive results, adulterated specimens, and substituted specimens to the Clearinghouse.
Substance Abuse Professionals (SAPs) — SAPs who evaluate drivers after a violation must register and report their evaluations and recommendations through the Clearinghouse.
Consortia/Third-Party Administrators (C/TPAs) — Organizations like BBB Mobile that manage testing programs on behalf of employers must register and can report certain information and conduct queries on behalf of their clients.
CDL Drivers — Drivers must register to provide consent for full pre-employment queries, and they can access their own Clearinghouse record at any time. They're not reporting violations — that's done by employers, MROs, and SAPs — but they need an account to consent to queries.
This is where I see the most confusion among Utah fleet managers. There are two types of Clearinghouse queries, and they serve different purposes at different points in the employment relationship.
A full query returns complete information about a driver's Clearinghouse record, including all violations, their current status, and whether a return-to-duty process has been completed. A full query requires the driver's electronic consent — the driver gets a notification through their Clearinghouse account and must approve the query before results are released to the employer.
When is a full query required? Before a CDL driver performs safety-sensitive functions for your company for the first time. That means every new hire, and it means before a driver transfers from a non-CDL position to a CDL position within your company. The full query must return a result with no unresolved violations before the driver can operate a commercial vehicle for you.
Here's the timing issue that catches employers: the driver consent process takes time. If the driver doesn't have a Clearinghouse account or doesn't respond to the consent request quickly, your pre-employment query stalls. Build this into your hiring timeline. Don't schedule a new driver's first day assuming the query will clear overnight.
A limited query tells you only one thing: whether the driver has information in the Clearinghouse that would disqualify them from safety-sensitive duties. It returns either "No record found" or "Violation in Clearinghouse — conduct a full query." It does not give you details about the violation. A limited query does not require driver consent — you can run it without the driver's real-time approval.
When is a limited query required? At least once per calendar year for every CDL driver you currently employ. This is the annual query requirement that some employers miss. You're not just querying at hire — you're querying every existing driver once a year, every year. If a limited query returns a violation flag, you must immediately conduct a full query (which does require consent) to get the details.
In practice: full query for new hires, limited query annually for your existing workforce. Keep records of both.
The Clearinghouse is only useful if violations actually get into the system. Here's what must be reported and by whom:
Verified positive drug test results — Reported by the MRO after review. This happens automatically when you're working with a compliant testing program that uses a registered MRO.
Alcohol test results of 0.04 or higher — Reported by the employer (or C/TPA on the employer's behalf). This is an employer responsibility, not the MRO's.
Refusals to test — Reported by the employer. A refusal is treated the same as a positive — it's a violation. Refusals include: not showing up for a test, not providing an adequate specimen without a medical explanation, leaving the collection site before completion, and certain other behaviors during the testing process.
Actual knowledge violations — If you observe a driver using drugs or alcohol while on duty, or you have direct evidence of a violation, that must be reported to the Clearinghouse. This one surprises some employers — it's not just lab results that get reported.
SAP evaluations and return-to-duty status — When a driver completes their SAP evaluation and begins the return-to-duty process, the SAP reports progress through the Clearinghouse. The employer must report when a return-to-duty test is completed and passed.
Let's say you run a pre-employment query on a new driver and the Clearinghouse returns a violation. What happens next?
First: the driver cannot perform safety-sensitive functions for your company. That's not a judgment call — it's a regulatory requirement. You cannot put them behind the wheel of a commercial vehicle, and you cannot allow them to perform any other safety-sensitive duty, until their Clearinghouse record shows a completed return-to-duty process.
Second: you don't have to do anything to resolve the violation. That's on the driver. They need to complete the SAP evaluation, follow the SAP's recommendations (which typically include treatment or education), pass a return-to-duty drug test, and complete the follow-up testing plan the SAP specifies. Only after all of that is documented in the Clearinghouse can they perform safety-sensitive functions again.
Third: you have a documentation obligation. Your records need to show that you ran the query, received the result, and acted appropriately. If an FMCSA auditor asks to see your Clearinghouse compliance records, "I forgot" isn't a defense.
FMCSA doesn't just send a warning letter for Clearinghouse violations. Civil penalties for failing to conduct required queries, failing to report violations, or allowing a driver with an unresolved violation to perform safety-sensitive functions can reach into the thousands of dollars per occurrence. For small carriers, a single enforcement action can be operationally significant.
Beyond the financial penalty, there's the liability exposure. If you hire a driver without running the required Clearinghouse query and that driver causes an accident — and it turns out they had an unresolved violation on their record — your legal exposure is substantial. The query isn't just a regulatory checkbox. It's documentation that you did your due diligence.
Queries are run through the FMCSA Clearinghouse website at clearinghouse.fmcsa.dot.gov. You'll need your registered employer account and the driver's CDL number. For a full query, you initiate the request and the driver receives a notification to their Clearinghouse account. For a limited query, you can run it directly once the driver provides their general written consent (which is typically part of your employment paperwork, not a transaction-by-transaction approval).
There's a cost per query. As of the most recent FMCSA fee schedule, full queries and limited queries both carry a per-query fee. FMCSA adjusts the fee periodically — check the Clearinghouse website for current rates.
C/TPAs like BBB Mobile can run queries on behalf of employers. If you want us to manage your annual limited query obligations as part of your consortium program, that's a conversation worth having. One less thing to track, one more compliance task handled correctly.
Your Clearinghouse obligations and your random testing consortium are connected. When a random test returns a positive, that result gets reported to the Clearinghouse. When a driver in your consortium is randomly selected and refuses to test, that refusal is also a Clearinghouse-reportable event. Your C/TPA has reporting obligations, and your testing documentation needs to be organized enough that everything gets reported correctly and on time.
For Utah owner-operators and small fleets working with BBB Mobile's consortium, we coordinate the reporting process so nothing falls through the cracks. Pre-employment queries are on your radar at hire. Annual limited queries are tracked as a program obligation. Violation reporting happens correctly through the right parties. You don't have to juggle the administrative pieces — we help you manage the compliance workflow.
I see four mistakes repeatedly with Utah trucking companies that are otherwise running solid programs:
Missing the annual limited query. Employers remember the pre-employment full query but forget to run the annual limited query on existing drivers. It's an easy compliance gap because there's no automatic reminder — you have to build the process into your annual calendar.
Waiting too long for driver consent on a full query. New driver starts Monday. You initiate the full query Friday. Driver doesn't have a Clearinghouse account. Monday comes and goes, no result yet, and now the driver is either sitting idle or — worse — you let them drive anyway. That's a violation. Run the query earlier in the hiring process.
Not reporting actual knowledge violations. If you catch a driver using or impaired, that's a Clearinghouse-reportable violation just like a positive test. Some employers handle it informally and never report it. That's non-compliant — and it leaves the next employer without information they're entitled to have.
Assuming an old violation is expired. Clearinghouse violations don't automatically disappear after a set time. They remain in the record until the return-to-duty process is fully completed and documented. A driver might have a five-year-old positive test on their record that's never been resolved — that's still a barrier to safety-sensitive employment.
The official source is FMCSA's Clearinghouse website: clearinghouse.fmcsa.dot.gov. The regulations are in 49 CFR Part 382, Subpart G. FMCSA also publishes guidance documents that are more readable than the regulatory text — worth bookmarking if you're managing your own compliance.
For Utah operators who want hands-on help — managing the query process, coordinating violation reporting, and tying it all into a functioning consortium program — BBB Mobile DOT Drug Test handles the compliance logistics. We work with Summit County, Wasatch County, Salt Lake County, and the broader Wasatch Front.

The FMCSA Drug and Alcohol Clearinghouse is a federal online database that records CDL driver drug and alcohol program violations. Employers, drivers, Medical Review Officers, and Substance Abuse Professionals all interact with it under 49 CFR Part 382, Subpart G.
Yes. Employers must run a full pre-employment query (with driver consent) before a CDL driver performs safety-sensitive functions, and a limited query at least once per year for every current driver.
Violations do not expire automatically. They remain in the record until the driver completes the full return-to-duty process and follow-up testing plan, and then for five years from the violation date (or until the process is complete, whichever is later).
CDL drivers, employers of CDL drivers, consortia/third-party administrators (C/TPAs), Medical Review Officers, and Substance Abuse Professionals must register to perform their respective Clearinghouse functions.
Letting a driver perform safety-sensitive functions without the required query is a violation that can result in civil penalties and findings in an FMCSA audit. Querying early in the hiring process avoids idle drivers and compliance gaps.
Yes. We help Utah operators manage the query process, coordinate violation reporting, and tie it into a functioning consortium program. Call (435) 395-1459 to talk through your situation.
