Requirements for Positives or Refusals: A CDL driver tests positive, or refuses to take, a DOT drug or alcohol test. What must the driver do to be able to resume performing safety sensitive functions, such as operating any type of commercial motor vehicle?
Answer
A CDL driver who tests positive on a DOT test or refuses to take a DOT test, must successfully complete the return-to-duty (RTD) process with a DOT qualified substance abuse professional (SAP). The requirements for the RTD process are found in 49 CFR Part 40, Subpart O. See 49 CFR 382.501, 382.503.
