DOT Drug Testing Services
What Is DOT Drug Testing?
DOT Drug Testing refers to the federally regulated drug and alcohol testing program overseen by the U.S. Department of Transportation (DOT). It ensures safety-sensitive transportation employees (drivers, pilots, rail workers, maritime personnel, etc.) remain free from prohibited substances through urine drug tests and federally compliant alcohol testing. DOT testing follows strict procedures, chain-of-custody protocols, and laboratory standards to protect both employee rights and public safety.
