Pre-Employment Drug Testing

Learn the first steps you need to take with Sky Drug Testing

Pre-Employment Testing Explained

Before a driver can perform any safety-sensitive duties, such as operating a commercial vehicle, they must complete a DOT pre-employment drug test. This is mandated under DOT regulations (49 CFR Part 40) and FMCSA regulations (49 CFR Part 382), even for drivers who already hold a Commercial Driver's License (CDL).

Here we will explain the process in which a potential hire can become qualified to drive for a motor carrier. An employer must receive a verified negative drug test result from a Medical Review Officer (MRO) or Consortium/Third Party Administrator (C/TPA) before a driver performs any safety-sensitive work.

Pre-Employment Drug Testing Requirements

Typically, a urine sample is collected for testing, and the potential driver must have a negative test result for the following substances:

  • Marijuana (THC)
  • Cocaine
  • Opioids
  • PCP
  • Amphetamines
