It is mandated by federal guidelines that anyone applying for a commercial drivers license must pass the Department of Transportation health exam. The purpose of this test is to check whether an applicant is physically capable of driving safely at the present time as well as in the foreseeable future.

Passing the exam successfully usually means you have 24 months before you need to do it again, although in some instances this period might be decreased if serious health issues might arise in the future.

Health Requirements

To pass the physical for the CDL you:

  • Vision in both eyes, as well as each eye individually, need to be 20/40, with visual improvement devices, such as glasses or contacts permitted.
  • Ability to distinguish color is necessary.
  • Should be able to perceive a forced whisper at a distance of at least 5 feet.
  • Your blood pressure must be lower than 160/100. Prescription medication may be used to control blood pressure.
  • Cannot have diabetes that requires insulin injections; diabetes controlled through a diet or oral medication is permitted.
