For commercial motor vehicle (CMV) drivers, the most important safety feature is YOU – the driver! Each time you turn the key, you are responsible for your own safety, as well as the safety of all the people who share the road with you. The physical examination you take for your medical certificate confirms that you are healthy enough to safely perform the demanding job of a CMV driver and keep our Nation’s roads safe.

What You Need to Know:

  • 49 CFR 382.603 is the applicable regulation requiring supervisors of commercial motor vehicle drivers who operate vehicles that require a commercial driver license to take 60 minutes of training on the symptoms of alcohol abuse and another 60 minutes of training on the symptoms of controlled substances use (120 minutes in total).  The purpose of this training is to teach supervisors to identify circumstances and indicators that may create reasonable suspicion that a driver is using or under the influence of alcohol or drugs, supporting referral of an employee for testing.
