DOT Urine drug testing

Regulated urine drug testing

Companies who choose to have a drug-free workplace program help to promote the health and safety of their employees. Many companies have the option of choosing to drug test their current or prospective employees, while others perform regulated drug testing mandated by the Federal government.

What is a regulated drug test?

A regulated drug test typically involves a urine or alcohol collection performed for specific agencies categorized as “safety-sensitive” workplaces because of the potential influence of their job on public safety. Safety-sensitive workplaces fall under the Health and Human Services (HHS) or Nuclear Regulatory Commission (NRC) testing authority, or are part of one of the following agencies under the U.S. Department of Transportation (DOT):

  • Federal Aviation Administration (FAA)
  • Federal Motor Carrier Service Administration (FMCSA)
  • Federal Railroad Administration (FRA)
  • Federal Transit Administration (FTA)
  • Pipeline and Hazardous Materials Safety Administration (PHMSA)
  • U.S. Coast Guard (USCG)

Which drugs are tested under a regulated drug screen?

Sometimes referred to as a “DOT drug test,” a regulated drug test includes these five drug classes:

  • Amphetamines
  • Cocaine
  • Marijuana
  • Opiates
  • Phencyclidine (PCP)

The regulated drug test collection process and Federal drug testing program requirements are guided by the DOT’s 49 CFR Part 40. It is a U.S. Department of Transportation rule that details the requirements for employers to conduct and adhere to workplace drug and alcohol testing programs for those occupations deemed to be safety-sensitive.

As drug use in the workplace continues to be a concern, regulated drug screens help promote testing rigor for both the federally mandated, safety-sensitive workforce, as well as non-regulated workplaces through the use of “DOT look-alike” panels that mimic the specifications of regulated urine drug tests.
