A DOT testing program involves more than booking a collection. A carrier needs to know which drivers are covered, who administers the program, where collections take place and how a result or missed selection is handled. This directory brings together listed providers offering different parts of that work.

DOT drug testing, random consortium and C/TPA services

FMCSA drug and alcohol testing generally applies to drivers operating vehicles that require a CDL on public roads. Holding a CDL or having a USDOT number does not, on its own, describe the full testing obligation. Explain the actual vehicle, driving duties and employer arrangement before buying a package.

A collection site, laboratory, medical review officer and consortium/third-party administrator have different responsibilities. Ask the provider which functions it performs directly, which are arranged through others and who the employer contacts when a time-sensitive collection is needed. For a random program, check how selections are communicated and how records remain available to the carrier.

FMCSA Clearinghouse support and SAP evaluations

Clearinghouse account administration and required queries are separate tasks that may be included in a testing package. A DOT SAP evaluation is a clinical step after a qualifying violation; it is not another name for a drug test. A SAP cannot promise a return-to-work date or bypass the employer’s testing and reporting duties.

Compare the collection network, hours, after-hours arrangements, charges for individual tests and access to reports. Confirm state coverage with the provider rather than assuming a nationwide directory profile means every nearby collection site is available.

Read the random testing consortium guide or Clearinghouse service guide before sending a request. Official applicability guidance is available from FMCSA.

DOT Drug and Alcohol Testing Providers: common questions

Do I need a DOT drug test because I have a USDOT number?

A USDOT number alone does not determine Part 382 testing coverage. The vehicle, CDL requirement and driving activity matter. Describe the operation to a provider before selecting DOT or non-DOT testing.

Is a consortium the same as a collection site?

No. A consortium/third-party administrator can manage program tasks and a random pool. A collection site collects specimens. Check who provides each part of the service and how their charges are separated.

Can an owner-operator manage a random pool alone?

A covered self-employed owner-operator must participate in a consortium random testing pool. Someone leased to a carrier should confirm which employer program covers the driving work.

Does completing the SAP process replace a return-to-duty test?

No. SAP evaluation and successful compliance reporting are separate from the required return-to-duty test and the employer’s decision about safety-sensitive work.
