The short answer
For drivers covered by Part 382, the employer generally needs a verified negative controlled-substances result from the MRO or C/TPA before the first safety-sensitive work. A collection receipt alone does not establish that result.
Section 382.301 includes a specific prior-program exception with verification and record requirements. Do not assume an old test or a driver’s statement satisfies it.
A practical example
The applicant finished a collection this morning and dispatch wants to assign a load. The hiring owner verifies the required result rather than treating “test taken” as “cleared.”
Your next steps
- Assign someone to verify the result or document an applicable exception.
- Keep testing separate from the Clearinghouse query and other hiring checks.
- Confirm all applicable release conditions before safety-sensitive work.
Read the separate Clearinghouse query guide.
Three events that should never share one checkbox
| Record or decision | What it addresses | What to check |
|---|---|---|
| Collection | The specimen was collected | Does not establish the verified result. |
| Verified result or exception | The applicable testing condition was satisfied | Confirm through the authorized process. |
| Hiring release | All applicable prerequisites were checked | Testing is only one part of the decision. |
Recruiting and dispatch need different information
Recruiting may coordinate the appointment while an authorized testing contact receives the result. Dispatch needs the company’s appropriate work-clearance decision, not unrestricted access to sensitive testing details. Define the communication path and make sure the person releasing the driver knows which applicable checks are complete.
Example: a driver brings an old negative result
An old result may prompt a question about the prior-program exception, but it does not establish the exception by itself. The employer needs the specific participation, testing, verification, and record conditions in §382.301. Ask the authorized program contact to verify the actual requirements rather than using the age of one document as the whole decision.
Document which task remains outstanding
If hiring is delayed, identify the missing milestone accurately: collection pending, verified result pending, required query incomplete, qualification record needing review, or another applicable issue. This lets staff address the actual problem without sending the driver through an unnecessary repeat task.
The hiring release needs a verified result
For a driver subject to the pre-employment controlled-substances testing requirement, the employer must receive a verified negative result before the first safety-sensitive function, unless an applicable regulatory exception is satisfied. A collection receipt, a laboratory status of “pending,” or the recruiter’s expectation of a negative result does not establish that result. The designated employer representative should have a documented release process that dispatch understands.
An exception needs supporting verification
Section 382.301(b) has specific conditions involving prior program participation and testing history. A driver’s statement that another company tested them is not enough to establish the exception. Check the employer-verification requirements before relying on it. Treat the testing requirement, Clearinghouse query and driver-qualification review as separate hiring tasks. A suggested release sheet can record each completed requirement without distributing confidential test details to everyone involved in dispatch.
