Report to the FMCSA Clearinghouse
Last Updated: 09/25/2026

Employers, or their designated C/TPA, must report certain drug and alcohol program violations and results to the FMCSA Drug and Alcohol Clearinghouse. Your company files these reports in its own account at the FMCSA Clearinghouse, or through a consortium/third-party administrator (C/TPA) it designates there. Med-Stop is not a C/TPA in the Clearinghouse: you cannot designate Med-Stop there, and Med-Stop does not run queries or report violations, return-to-duty results, or follow-up results for your company. MROs and SAPs report their own items.

What employers or their C/TPA must report

  • An alcohol confirmation test with a concentration of 0.04% or higher.
  • A refusal to test (alcohol) as specified in 49 CFR 40.261.
  • A refusal to test (drug) not requiring a determination by the MRO, as specified in 49 CFR 40.191.
  • Actual knowledge, as defined in 49 CFR 382.107, that a driver has used alcohol on duty, used alcohol within four hours of coming on duty, used alcohol prior to post-accident testing, or has used a controlled substance.
  • Negative return-to-duty (RTD) test results (drug and alcohol testing, as applicable).
  • Completion of follow-up testing.

Reporting deadline

Employers must report required information about a driver by the close of the third business day after they obtain it. If a report is late, you must provide an explanation. See §382.705 Reporting to the Clearinghouse.

Keep Med-Stop records complete

The tests and violations recorded in Med-Stop give you the dates, results, and documents you need for your own reports, so keep them correct. You are responsible for keeping applicant and employee information up to date. If a pre-employment or return-to-duty test was done outside Med-Stop, enter it in Med-Stop so your records stay complete.

Find tests that may need reporting

Tests that may need to be reported, such as refusals determined by the Designated Employer Representative, appear on the Welcome screen in the Abnormal Urine Drug and Alcohol Tests section.

The test window may still show Clearinghouse reporting options from Med-Stop's former Clearinghouse service. Med-Stop does not file the report for your company; report the result in the Clearinghouse.

Actual knowledge violations

Employers who have actual knowledge that a driver used alcohol or controlled substances in violation of Part 382, Subpart B, must report it under 49 CFR 382.705(b)(4). Actual knowledge, as defined in 49 CFR 382.107, is based on the employer's direct observation of the employee, information from the driver's previous employers, a traffic citation for driving a CMV under the influence of alcohol or controlled substances, or the employee's admission of alcohol or controlled substance use, except as provided in 49 CFR 382.121.

These reports require detailed violation information and supporting documents, audio, and video. Report them from your company's Clearinghouse account. You can record the violation in Med-Stop and mark it as reported.
