  • marijuana
  • cocaine
  • heroin
  • LSD
  • methamphetamine


The FMCSA’s list also includes certain prescription medications like:

  • hypnotics

Plus, there are over-the-counter medications on the FMCSA prohibited substance list including:

  • cough suppressants containing codeine

What Is the DOT & FMCSA Disqualification Process?

Even if a driver has a prescription for marijuana, the FMCSA will not allow prohibition to be lifted on marijuana at all. Also, say that you're a CDL driver that takes a prescription medication without having a valid prescription. That means you will be disqualified from driving.

These rules state that any driver taking a Schedule I or II controlled substance must disclose this information immediately and provide proof of valid prescription from a medical doctor. Drivers may also be disqualified for taking any other Schedule drugs, including amphetamines, benzodiazepines, and others that are habit-forming or narcotic.

It's important for CDL drivers get DOT Certification to understand the possible ramifications of these regulations if they take medications prescribed by their doctor. When a CDL driver has a valid prescription from a licensed medical doctor for a non-schedule I drug, they won’t be disqualified as long as the doctor officially states that the medication(s) will not impair the driver’s ability to operate commercial vehicles.
