DOT Drug Testing

DOT drug testing is a federally regulated program required for employees in safety-sensitive transportation roles, such as commercial drivers, pilots, and railroad workers. The Department of Transportation (DOT) sets strict guidelines to ensure that individuals responsible for public safety are not impaired by drugs or alcohol while performing their duties.

​Legal issues can arise when test results are challenged, or when questions surface regarding the procedures followed during collection and analysis. Toxicology provides essential insight by explaining detection limits, interpreting results, and determining whether tests were conducted in line with federal standards.
