What is required to pass a CDL exam?

Anyone who wants to drive a commercial motor vehicle must get a CDL physical to verify they don’t have health issues that would interfere with the safe handling of a commercial vehicle.

These are a few examples of the requirements you must meet to pass your CDL exam in the state of Arkansas:


Vision that is correctable to 20/40 in both eyes. Both glasses and contact lenses are allowed for this correction.

Color recognition

You must be able to clearly distinguish colors. Color blindness will exclude you from a commercial vehicle license.


You must have hearing that allows you to recognize a forced whisper at a distance of five feet.

Blood pressure

Your blood pressure must be in the normal range to be certified to drive for two years. If your blood pressure is higher than 140/90, you may get a medical certificate that’s good for three months to a year.

The maximum allowable blood pressure is 160/100. Using medication to control your blood pressure is permissible, but your medical certificate will only be good for one year.


If you have diabetes, it must be controllable through lifestyle and diet, or through oral medication. Insulin-dependent diabetics will not be issued a CDL commercial license.

Blood sugar

Your blood sugar must be under 200.


You may not use amphetamines, narcotics, or any other habit-forming medications.

Cardiovascular disease

If you suffer from cardiovascular disease, you must submit to a stress test and have your physician send a written note stating you’re capable of driving a commercial motor vehicle without restrictions.

What should I expect during a CDL physical exam?

Dr. Yang takes a full medical history as part of your CDL exam. This includes information about your history of illnesses, chronic diseases, and injuries, as well as past or present drug and alcohol use. You’ll be specifically screened for heart disease, respiratory illnesses, diabetes, and stroke.

You may also be evaluated for problems that would affect your ability to stay alert during long drives, such as sleep disorders and epilepsy.

A CDL physical exam is comprehensive, covering every part of your body, including:

  • Vision and hearing
  • Lungs
  • Heart
  • Ears, nose and throat
  • Balance
  • Reflexes
  • Movement

Dr. Yang will perform a urinalysis and may order blood tests or an X-ray if needed.

How long are the results of my CDL exam valid?

For most drivers, your CDL certification is valid for 24 months from the date of issue. You may receive a medical certificate that expires sooner if you have a medical condition that needs to be monitored or if you’ve been given time to improve an existing condition.
