Drug Testing for DOT

Big changes were introduced by the DOT in 2018!

As of January 1, the DOT drug test, the test for controlled substances, will monitor use of the following 5 classes of drugs:

  • Marijuana
  • Cocaine
  • Four semi-synthetic opioids (i.e., hydrocodone, oxycodone, hydromorphone, oxymorphone) *effective in 2018
  • Amphetamines and methamphetamines
  • Phencyclidine – PCP

There’s an increased focus on opioids, and the drug panel changes are effective across the entire DOT. Every agency under jurisdiction must make changes necessary for compliance.

The 2018 changes removed the blind specimen requirement and methylenedioxyethylamphetamine (MDEA) and added methylenedioxyamphetamine (MDA) to the initial amphetamines test. Some of the changes make it very clear marijuana is not permitted in DOT safety-sensitive roles, even if the state has legalized use.

The Medical Review Officer examing the test results may also validate prescriptions with the new language accounting for the testing of four opioids commonly prescribed by doctors.

CDL Drug Testing

The FMCSA states no CDL class driver can have or use (on or off duty):

  • Any schedule I substance
  • Any amphetamine or formulation of an amphetamine (including pep pills and bennies)
  • Narcotics or derivatives
  • Any other substance that makes driving unsafe

If a driver produces a positive DOT drug test, he/she must be immediately removed from the safety-sensitive position. If tampering is suspected, the employee is to be treated as someone who refused to test and be immediately removed from their role.

DOT drug test required information

DOT drug tests analyze the urine for evidence of drug use. Test subjects need to show up with the following information indicated on the DOT-approved form:
