Clearinghouse Explained
DOT Drug & Alcohol Clearinghouse, explained (without the confusion).
The FMCSA Clearinghouse is where drug and alcohol program violations are recorded and where employers run required queries before hiring and at least annually. This page breaks down what it is, who it applies to, how consent works, what “limited vs full” means, and what happens during return-to-duty.
- Know when an employer must run a pre-employment query and an annual query.
- Understand driver consent: what you approve, when you approve it, and what “refusal” means.
- Learn the difference between a limited query (status check) and a full query (details).
- Get a clean overview of the Return-to-Duty (RTD) process and follow-up testing expectations.
FMCSA Clearinghouse Explained: What It Is, What It Shows, and How to Stay Employable
The FMCSA Drug & Alcohol Clearinghouse is a federal database that stores certain DOT drug and alcohol program violations for CDL/CLP drivers, plus return-to-duty (RTD) status details. Employers use it to make sure a driver is not prohibited from performing safety-sensitive work.
This page is built to be practical: what gets reported, what employers must query, how consent works, and what to do if a record exists. It’s educational content (not legal advice).

What the Clearinghouse is (in plain language)
Think of the Clearinghouse as the “yes/no gate” for safety-sensitive work: employers query it to see whether a driver has a prohibition on their record (and to confirm RTD status when applicable).
Who it applies to
- Drivers: CDL/CLP drivers subject to DOT drug/alcohol testing rules (FMCSA part 382).
- Employers: motor carriers/employers who must query before hiring and at least annually.
- Service agents: MROs, SAPs, and C/TPAs involved in testing and RTD reporting.
As-of: eCFR Title 49 (Transportation) shows Part 382 Subpart G up to date as of January 15, 2026.
Drivers: one crucial detail
Drivers are not required to register — but a driver must be registered to provide electronic consent for a full query (including all pre-employment queries) and to view their own record.
If you’re job hunting, register once and set your preferred contact method (email or mail).
Registers (recommended), responds to full-query consent requests, and can view their record.
Must run a full pre-employment query, and must query at least annually (often via limited query).
Employer can designate a consortium/third-party administrator to run queries and manage workflows.
Reports certain DOT drug test results to the Clearinghouse on a deadline.
Manages RTD process steps and reports key RTD milestones to the Clearinghouse.
Stores violation + RTD info and releases records based on query type and consent.
Queries & consent (the part that trips people up)
There are two query types: limited and full. Limited can satisfy the annual requirement. Full is required for pre-employment and any time a limited query returns “record exists.”
Shows only whether a record exists. It does not release violation details.
- Use case: annual query requirement (common).
- Consent: general consent obtained outside the Clearinghouse; may be multi-year.
- Result: “No record” or “Record exists.”
As-of Jan 2026: limited query can satisfy annual query requirement (382.701).
Releases specific violation/RTD details to the employer.
- Use case: required before hiring for safety-sensitive work.
- Consent: driver must submit electronic consent in the Clearinghouse.
- If limited says “record exists”: employer must run full query within 24 hours.
As-of Jan 2026: pre-employment requires a full query (382.701).
Run a full query before the driver performs safety-sensitive work.
Run at least one query per year for each covered employee (often limited).
Run a full query within 24 hours or pull the driver from safety-sensitive work.
No consent = no full query = driver can’t perform safety-sensitive functions.
Retain query records for 3 years (registration can satisfy recordkeeping as of Jan 6, 2023).
For employers: you must have a Clearinghouse account (registration required) and a query plan to run queries. For drivers: register once, confirm contact method, and respond quickly to consent requests when job hunting.
“Prohibited” status (what it means operationally)
If a Clearinghouse query shows an unresolved violation, the employer generally may not allow the driver to perform safety-sensitive functions unless the record shows required RTD steps have been satisfied.
Common “what shows up” buckets
- Positive / adulterated / substituted drug test (DOT-required test).
- Alcohol confirmation ≥ 0.04.
- Refusal to test (DOT-defined refusal).
- Actual knowledge of certain alcohol/controlled substance use violations (employer report).
- RTD records: SAP completion, negative RTD test, follow-up testing completion.
The Clearinghouse stores violations under FMCSA rules and also records RTD steps when completed.
The “job hunting” reality
A driver can’t “talk their way around” a full query. If you have a record, your fastest path back to steady employment is completing the RTD process (SAP steps + negative RTD test + follow-up plan).
If you’re a carrier: don’t guess. Use the decision loop above and document consent + queries.
Note: This is educational; always follow the applicable CFR text and your attorney/TPA guidance for edge cases.
Reporting & timelines (why records appear fast)
A lot of Clearinghouse confusion comes from timing. Violations and RTD milestones have specific reporting deadlines for employers, MROs, and SAPs.
Employers and service agents must register before accessing or reporting in the Clearinghouse.
As-of Jan 2026: registration requirement is in 49 CFR 382.711.
Employers purchase a query plan inside the Clearinghouse to run queries (and C/TPAs can run them on your behalf).
As-of Jan 2026: see Clearinghouse “Query Plans” guidance.
Practical takeaway: the Clearinghouse is designed to update quickly — don’t assume you have “time before it hits.”
Return-to-duty (RTD) process (what “getting back” actually means)
RTD is not a vibe — it’s a defined sequence: SAP assessment, recommended education/treatment, eligibility determination, RTD test, then follow-up testing plan management.
Violation is reported and appears in the Clearinghouse on required timelines.
Driver completes initial SAP evaluation and receives a plan.
Driver completes the prescribed steps and provides documentation to SAP.
SAP determines eligibility for return-to-duty testing and reports it.
Negative RTD test + follow-up plan management to complete the process.
The Clearinghouse records RTD milestones (SAP completion/eligibility, negative RTD test, and follow-up testing completion).
Templates (copy/paste ready)
These templates help you run the Clearinghouse cleanly: general consent for limited queries, driver “job hunt readiness” checklist, and a simple employer query log to keep your proof tight.
Keep the signed form with your records (3-year retention commonly referenced for consent/query proof).
Most hiring delays happen because consent requests go unanswered.
This log is your audit-proof “receipt trail.”
Keep it simple: “grant consent so we can complete the required full query.”
This is a simple way to document compliance with the 24-hour rule.
These templates are practical starting points. Always align with your counsel/TPA and your company policies.
