DOT Testing Information
The Department of Transportation (DOT) mandates drug testing for individuals in safety-sensitive positions within DOT-regulated transportation industries. The primary goal is to ensure a safe and drug-free workforce within these crucial sectors.
Here's an in-depth look at DOT drug testing:
1. Scope of regulations and covered employees
DOT regulations apply to various safety-sensitive roles across several transportation industries, including commercial motor vehicle drivers (FMCSA), pilots and air traffic controllers (FAA), railroad employees (FRA), transit operators (FTA), pipeline workers handling hazardous materials (PHMSA), and commercial vessel crew members (USCG).
2. Testing circumstances
DOT drug testing is required in specific situations:
-
Pre-Employment: Before starting a safety-sensitive role.
-
Random: Unannounced testing of a portion of employees annually, with rates set by each DOT agency based on prior violation rates.
-
Reasonable Suspicion: Based on observable signs of drug use.
-
Post-Accident: Following accidents meeting certain criteria.
-
Return-to-Duty: After a violation and completing a process with a Substance Abuse Professional (SAP). This test is directly observed.
-
Follow-Up: Unannounced testing after returning to duty, as prescribed by an SAP. These tests are directly observed.
3. Test panel and methods
-
Substances Tested: DOT drug tests screen for marijuana, cocaine, opioids, PCP, and amphetamines, including related substances like Ecstasy and certain prescription opioids.
-
Accepted Methods: Urine testing is the primary method, with oral fluid (saliva) testing introduced as an alternative since June 1, 2023.
-
Detection Windows (Urine Testing): Detection times vary, from a few days for single use of some substances to up to 30 days for chronic marijuana use. Opioids and PCP can be detected for several days.
-
Hair Follicle Testing: While not yet federally approved for DOT testing, hair follicle testing is being considered for its longer detection window, though concerns about potential discrimination have been raised.
