What is Evaluated During a DOT Physical?


The physical examination required of most commercial motor vehicle (CMV) drivers is called a medical fitness for duty exam. The medical examiner must consider the driver’s physical condition, mental condition, and medical treatment, and then ask themselves “Does the driver pose a risk to public safety?”

Physical Condition

  • Are there any symptoms that may interfere with the driver’s ability to drive? For example, arrhythmia that causes fainting?
  • Can the driver stop the vehicle before becoming incapacitated?

Mental Condition

  • Are the driver’s interactions with other people appropriate, responsible, and nonviolent?
  • Can the driver make appropriate decisions, solve problems independently, and function in different environments?

Medical Treatment

  • Can the driver perform tasks safer with treatment than without treatment?
  • Are there any side effects from the treatments that may interfere with safe driving?
