DOT Drug and Alcohol Consortium for Owner-Operators

Written by the Logity Dispatch team for owner-operators and small fleets. Every rule below was checked against its own primary source on 5 October 2026: 49 CFR part 382 as served by the eCFR API at title 49’s 1 October 2026 issue date, and the owner-operator pages, FAQs and factsheets on the FMCSA Clearinghouse site (clearinghouse.fmcsa.dot.gov). This article explains the federal rules for a carrier with one truck and one driver who is also the owner. It is not legal advice.

Why does a one-truck carrier need a consortium at all?

Because the rules treat you as two people. Part 382 defines an employer as “a person or entity employing one or more employees (including an individual who is self-employed)” (382.107). Once you hold your own authority and drive your own truck, you are that self-employed employer, and you are also the driver.

Section 382.103(b) spells out what follows: “An employer who employs himself/herself as a driver must comply with both the requirements in this part that apply to employers and the requirements in this part that apply to drivers.” The same paragraph closes the obvious gap. You cannot run a random program with yourself as the only name in the hat, because “An employer who employs only himself/herself as a driver shall implement a random alcohol and controlled substances testing program of two or more covered employees in the random testing selection pool.”

A consortium solves that problem. It pools drivers from many small employers so the random selection is real. The FMCSA Clearinghouse makes the same point from its side: “Note: Working with a C/TPA to manage a drug and alcohol testing program is a requirement of all owner-operators” (Query Plan factsheet, FMCSA-MCE-19-010).

What is a consortium, and what is the Clearinghouse?

They are different things, and new carriers often mix them up. A consortium/third-party administrator (C/TPA) is a private service agent. Part 382 defines it as “a service agent that provides or coordinates one or more drug and/or alcohol testing services to DOT-regulated employers” (382.107). The definition expressly covers “groups of employers who join together to administer, as a single entity, the DOT drug and alcohol testing programs of its members (e.g., having a combined random testing pool).”

The Drug and Alcohol Clearinghouse is the federal database. FMCSA’s FAQ describes it as “a centralized database that employers use to report drug and alcohol program violations and to conduct queries”. You do not test anyone in the Clearinghouse. You register, designate your C/TPA, buy queries, and read results there.

	Consortium / C/TPA	FMCSA Clearinghouse
What it is	A private service agent you choose and contract with	FMCSA’s online database of drug and alcohol program violations
What it does for you	Puts you in a random pool, makes random selections, coordinates testing, and reports your violations to the Clearinghouse	Holds violation and return-to-duty records; answers your limited and full queries
Who you pay	The C/TPA, on terms you agree with it	FMCSA, for a query plan: $1.25 per query (Clearinghouse FAQ and Query Plan factsheet, checked 5 October 2026)
Where the rule sits	382.103(b), 382.107, 382.305(j)(2), 382.705(b)(6)	382.701 to 382.711

Do you need a consortium if you are leased onto another carrier?

Usually not for the employer side. The Clearinghouse owner-operator page says it plainly: “If you operate under another employer’s authority, you do not need to meet the Clearinghouse requirements for employers.” The owner-operator brochure (FMCSA-MCE-19-009, May 2023) draws the same line by registration role: “Owner-operators who operate under another motor carrier’s USDOT Number should register in the Clearinghouse as a driver.” In that case the carrier you are leased to is your employer for part 382, and its program covers your testing.

The rest of this article is for the other case in the brochure: “Owner-operators who operate under their own authority/USDOT Number must register as an employer.”

What has to be in place before your first load?

Here is the order that works, with the rule behind each step. Most of it happens once; two pieces repeat every year.

1. Pick a C/TPA and agree terms with it. The brochure says: “As an owner-operator, you are required to work with at least one consortium/third-party administrator (C/TPA). You must reach out to your C/TPA(s) before designating them as your C/TPA(s) in the Clearinghouse.”
2. Take a pre-employment drug test. Under 382.301(a), the test is required “Prior to the first time a driver performs safety-sensitive functions for an employer”, and no employer may let the driver perform those functions until it has received a verified negative result from the MRO or C/TPA. Section 382.301(b) has a narrow exception for a driver who was in a compliant testing program within the previous 30 days and either tested within the past 6 months or was in a random program for the previous 12 months. The employer using it must contact the earlier program and obtain and keep the records that 382.301(c) lists.
3. Register in the Clearinghouse as an employer. The owner-operator page notes that a registered motor carrier should already have an FMCSA Portal account, and signing in with it “can help your Clearinghouse registration go more smoothly.”
4. Designate your C/TPA in the Clearinghouse. Until you do, nothing else works: “You will not be able to take any action in the Clearinghouse until you have designated your consortium/third-party administrator (C/TPA).” The C/TPA then has to accept: “C/TPAs must accept an employer’s designation in the Clearinghouse before they can access the Clearinghouse on that employer’s behalf” (Designate a C/TPA guide).
5. Buy a query plan yourself. “As employers, owner-operators must purchase a query plan to meet their query requirements. C/TPAs cannot purchase query plans on behalf of employers.”
6. Give consent and run your queries. A pre-employment full query on yourself, then at least one query a year. The next sections cover both.
7. Put your policy and educational materials on file. Section 382.601 requires materials that explain part 382 and your policies, distributed to each driver before testing starts, and 382.601(d) requires a signed statement from each driver certifying receipt. As the only driver, that is you.

How does random testing work when you are the only driver?

Your C/TPA runs it, but the duty to get it right stays with you. Section 382.305(j)(2) says: “As an employer, you may use a service agent (e.g., a C/TPA) to perform random selections for you, and your covered drivers may be part of a larger random testing pool of covered employees. However, you must ensure that the service agent you use is testing at the appropriate percentage established for your industry and that only covered employees are in the random testing pool.”

Section 382.305(b) sets the minimum annual random testing rates at 50 percent of the average number of driver positions for controlled substances and 10 percent for alcohol, except as later paragraphs of the same section provide. Those paragraphs let FMCSA raise or lower the rates, with any change published in the Federal Register and applying from 1 January of the calendar year after publication. Ask your C/TPA in writing which rates it is testing at for the current year.

Three rules shape the day you are selected:

• Random tests must be unannounced (382.305(k)(1)).
• Test dates must be “spread reasonably throughout the calendar year” (382.305(k)(2)).
• A driver notified of selection must proceed to the test site immediately (382.305(l)).

Missing the call is not a scheduling problem. The part 382 definition of refusal to submit includes “the failure of an employee (including an owner-operator) to appear for a test when called by a C/TPA” (382.107). Keep the C/TPA’s phone number and your current contact details matched, and if your C/TPA uses email or a portal, check it on the road. If you have a dispatcher, our article on what happens when a random test lands mid-load covers how the load gets handled.

Which Clearinghouse queries do you run on yourself, and what do they cost?

Two kinds, and both need consent. A limited query tells you whether a driver’s record holds any violation information without releasing the details. A full query releases the details and needs the driver’s specific consent given electronically inside the Clearinghouse (382.703(b)).

• Pre-employment: a full query before the driver first performs safety-sensitive functions (382.701(a)). For a new carrier, the driver is you.
• Annual: “Employers must conduct a query of the Clearinghouse at least once per year for information for all employees subject to controlled substance and alcohol testing under this part” (382.701(b)(1)). A limited query satisfies this (382.701(b)(2)).
• If a limited query finds something: the employer must run a full query within 24 hours, or the driver may not keep performing safety-sensitive functions (382.701(b)(3)).

Consent for limited queries can last longer than a year. Section 382.701(b)(2) says “The individual driver may give consent to conduct limited queries that is effective for more than one year”, and the Clearinghouse FAQ adds that “the limited consent request must specify the timeframe the driver is providing consent for.” FMCSA publishes a sample limited consent form. Under 382.703(a), you keep each consent for 3 years from the date of the last query.

The price is set by FMCSA, not by your C/TPA. The Clearinghouse FAQ says: “Queries are a flat rate of $1.25 per query.” The Query Plan factsheet confirms a “Flat per query rate ($1.25), for limited and full queries”, says bundles “never expire”, and says “Query plans may be purchased from the FMCSA Clearinghouse only.” If a limited query shows information and you follow with a full query, the factsheet says “the employer will only be charged once for both queries.” At that rate, a one-truck carrier pays $1.25 for the pre-employment full query on you as its driver and $1.25 for each annual query after that (checked 5 October 2026).

Your C/TPA may run the queries for you once you have designated it and given it that authority. The Clearinghouse FAQ answer for owner-operators says: “An owner-operator’s designated consortium/third-party administrator (C/TPA) may conduct queries on their behalf.” The query plan still has to be yours.

Who reports your violations if you are the employer and the driver?

Not you. Section 382.705(b)(6): “An employer who employs himself/herself as a driver must designate a C/TPA to comply with the employer requirements in paragraph (b) of this section related to his or her own alcohol and controlled substances use.” The brochure puts it in one line: “If an owner-operator commits a drug and alcohol program violation, this information must be reported by the C/TPA.”

This is also the one place where responsibility moves. In general, 382.705(c) says the employer “retains ultimate responsibility for compliance with this section” even when a C/TPA does the work. It then makes an exception: “An employer does not retain responsibility where the C/TPA is designated to comply with employer requirements as described in paragraph (b)(6) of this section.” For everything else in part 382, including random rates, consents, queries and records, the responsibility stays with you.

Reporting runs on tight clocks. Employers report by “the close of the third business day” after obtaining the information (382.705(b)(1)), and MROs report verified results within 2 business days (382.705(a)). If you change C/TPA, update your Clearinghouse registration: under 382.711, employers “must update any changes to this information within 10 days.”

Who	What they do for a one-truck carrier	Rule
You, as employer	Register in the Clearinghouse, designate and keep a C/TPA, buy the query plan, get consents, make sure the pool and rates are right, keep records	382.103(b), 382.305(j)(2), 382.701, 382.703, 382.711
You, as driver	Take the pre-employment test, go to random tests immediately, give consent, respond to consent requests in the Clearinghouse	382.301, 382.305(l), 382.703
Your C/TPA	Random pool and selections, test coordination, reporting your violations, queries if you authorize it	382.107, 382.305(j)(2), 382.705(b)(6)
Medical review officer (MRO)	Verifies drug test results and reports to the Clearinghouse	382.705(a)

Which records do you have to keep, and for how long?

Section 382.401 sets the schedule. Records go in “a secure location with controlled access”, and they must be available for inspection at your principal place of business within two business days after an authorized FMCSA representative asks (382.401(d)).

Keep for	What	Rule
5 years	Alcohol results of 0.02 or greater, verified positive drug results, refusals, evaluations and referrals, and records of running the testing program	382.401(b)(1)
3 years	Each Clearinghouse query and its results; each driver consent from the date of the last query	382.701(e), 382.703(a)
2 years	Records of the collection process	382.401(b)(2)
1 year	Negative and canceled drug results, and alcohol results below 0.02	382.401(b)(3)

Two practical notes. First, 382.701(e) adds: “As of January 6, 2023, an employer who maintains a valid registration fulfills this requirement”, so keeping your Clearinghouse registration active covers the query record. Second, the program records under 382.401(c)(6)(i) include your agreements with “consortia, and third-party service providers”, so keep the signed C/TPA agreement and any renewal with your files. Our guide to what triggers a DOT audit and how to pass it covers how those files get reviewed.

What comes after the consortium is set up?

The setup is a few hours of work. Keeping it current is what trips carriers up later: the annual query nobody calendared, the consent that expired, the C/TPA change that never made it into the Clearinghouse within 10 days, the random selection email sitting unread while you were under a load.

That ongoing part is what our safety and DOT compliance service is built for. The service covers drug and alcohol testing program management alongside driver files and ELD logs, and it runs a compliance calendar with automated reminders for renewals and deadlines. It is month to month with no restrictive contract, and setup is free. If you would rather start with a conversation, contact us and tell us where your testing program stands today.

Frequently asked questions

Can an owner-operator be in a random pool alone?

No. Under 49 CFR 382.103(b), an employer who employs only himself or herself as a driver must run a random testing program of two or more covered employees in the selection pool. Joining a consortium is how one-truck carriers meet that rule.

Can my C/TPA buy my Clearinghouse query plan?

No. The FMCSA Clearinghouse says owner-operators, as employers, must purchase a query plan themselves and that C/TPAs cannot purchase query plans on behalf of employers. Your designated C/TPA may run the queries for you.

How much does a Clearinghouse query cost?

FMCSA charges a flat $1.25 per query, limited or full, bought as a query plan from the Clearinghouse only, as checked on 5 October 2026. A one-truck carrier needs a pre-employment full query on its driver, which is you, and then at least one query a year.

Who reports a positive test if I am the only driver?

Your C/TPA. Under 49 CFR 382.705(b)(6), an employer who employs himself or herself as a driver must designate a C/TPA to report his or her own violations, and in that case the employer does not keep responsibility for that reporting.

Do I need a consortium if I am leased onto another carrier?

Usually not for the employer requirements. The Clearinghouse says that if you operate under another employer’s authority, you do not need to meet the Clearinghouse requirements for employers. You register as a driver, and the carrier’s program covers your testing.
