DOT Compliance

For those currently employed or seeking employment with the U.S Department of Transportation (DOT), it’s important to remain mindful of the various industry drug and alcohol testing requirements. In 1991, the U.S Congress passed the Omnibus Transportation Employee Testing Act, which required DOT agencies to enforce drug and alcohol testing for safety-sensitive transportation industry employees.

The DOT consists of a wide array of government sectors, such as the Federal Motor Carrier Safety Administration (FMCSA), the Federal Railroad Administration (FRA), and the Federal Transit Administration (FTA). From bus drivers to locomotive engineers, employees and employers must refer to position-specific DOT regulations regarding drug and alcohol policy to ensure complete DOT compliance.

DOT Drug Testing Compliance

DOT Pre-Employment Drug Testing

Applicants seeking employment through the DOT must refer to sector-specific drug and alcohol policy to understand pre-employment drug testing requirements. DOT positions that require employees to possess a commercial driver’s license (CDL) and operate government vehicles mandate that applicants submit to drug testing prior to beginning employment. A DOT background check may additionally be required to ensure a safe driver’s record for the position and necessary licensing.

According to DOT regulation, 49 CFR Part 40, the pre-employment drug testing process will consist of a urinalysis drug test. Specimens will be collected by qualifying personnel and tested through a U.S. Department of Health certified laboratory. Although not a requirement for pre-employment, a DOT employer may also choose to test for alcohol in addition to DOT drug testing.

DOT Random Drug Testing

Depending on the DOT agency and respective position, many employees will be required to agree to random drug and alcohol testing. According to DOT random drug testing best practices, employers are required to conduct random drug and alcohol testing using a scientifically-valid method, such as a computer-based random number generator.

Furthermore, depending on the specific DOT agency in which random testing is being conducted, employers must meet their agency’s annual drug testing rate requirement. When working to reach each required rate, testing must still be spread reasonably over the course of the year and ensure each employee has an equal chance of being selected.

DOT Drug and Alcohol Testing Requirements

When conducting DOT employee drug and alcohol testing, specific testing criteria must be met to remain in complete DOT compliance. Department of Transportation (DOT) drug testing regulations require the use of a 5-panel drug test which screens for marijuana (THC), cocaine, amphetamines, opioids, and phencyclidine (PCP). Specimens must also be analyzed through a U.S. Department of Health & Human Services certified laboratory. For DOT breath alcohol testing, regulations require testing to be conducted by a certified screening test technician (STT) or a breath alcohol technician (BAT).
