Drug & Alcohol Clearinghouse

What is a refusal?

View the PDF Handout

Drivers who are required to comply with Part 382 may not refuse to take a DOT drug or alcohol test. Refusals are reported to the Clearinghouse by either the motor carrier or the medical review officer (MRO) and include all of the following:

  • Failing to appear or showing up late for the test (not including pre-employment tests).
  • Refusing to provide a breath or urine specimen.
  • Failing to stay at the testing site until the testing process is done (except in the case of a pre-employment test where the driver leaves the testing site before the testing process commences).
  • Failing to submit enough saliva or breath if a physician determines that there is no medical explanation for a driver’s failure to provide enough breath or urine.
  • Failing to cooperate with any part of the testing process.
  • Failing to allow observation or monitoring of a urine collection, when required.
  • Failing or declining to take an additional drug test as directed by the employer or collector.
  • Admitting to adulterating or substituting the urine specimen.

A refusal to test carries the same consequences as a failed drug or alcohol test: removal from safety-sensitive functions and completion of the SAP evaluation and return-to-duty process and follow-up testing.
