What is a CDL medical exam?

In order to obtain a commercial driver’s license (CDL) or work with the Metropolitan Transportation Authority (MTA), it is necessary to first undergo an MTA/CDL physical exam—also known as a Department of Transportation (DOT) physical exam. The exam is conducted by a DOT medical examiner who may require you to have a sleep apnea test in order to pass the examination. Sleep apnea testing can be done at a sleep medicine clinic, such as eos sleep diagnostics, and generally takes place overnight in a sleep lab.

Are MTA workers required to have a sleep apnea test?

Sleep apnea screenings are now conducted for MTA employees in order to prevent accidents due to falling asleep while operating a train. While it isn’t required by regulation, the MTA has enforced this process as a preventative measure because they recognize the safety benefits of sleep apnea screening. If a screening is conducted on an MTA employee and results in a diagnosis for sleep apnea, he/she must undergo sleep apnea treatment in order to remain eligible to work with MTA.

Will I need to do a sleep apnea test for my DOT physical exam?

Not everyone will need to have sleep apnea testing in order to obtain their commercial driver’s license (CDL). However, if the doctor performing your DOT physical exam recommends a sleep apnea test based on your personal medical history, family medical history, or current health condition, you will need to have the testing before you are eligible to obtain your CDL.

Your CDL examiner may recommend a sleep apnea test if you suffer from any of the following symptoms of sleep apnea:

  • Snoring
  • Loud gasping or snorting sounds during the night
  • Sudden awakenings during the night
  • Morning headaches
  • Daytime sleepiness
  • Mood swings/irritability
  • Lowered daytime focus
  • Decreased libido
  • Memory loss

Additionally, a CDL examiner may recommend a sleep study if you have any of the following health conditions that are considered risk factors for sleep apnea:

  • Excess weight/obesity
  • Narrowed airway
  • Neck circumference that is larger than 17 inches
  • Family history of sleep disorder
  • Nasal airway obstruction
  • Smoking
  • Alcohol use

What does a CDL exam involve?

A CDL exam is required in order to obtain your commercial drivers license (CDL). In general, you must be over 18 years of age and own a valid drivers license to apply. Additionally, you’ll be required to pass a CDL exam, which covers a number of driving topics available on your state’s DMV website.

In some cases, your examiner will require that you also undergo a sleep study test prior to passing your exam. These can be done at eos sleep diagnostics, and follow the procedure for a regular sleep study.
