What is involved in a CDL exam?

The purpose of a commercial driver’s license exam is to determine whether you are currently, and for the foreseeable future, physically and mentally capable of safely driving a commercial motor vehicle.

Your High Rock Internal Medicine provider reviews your medical history and performs a complete physical examination, including vision and hearing tests. You’ll also be asked to provide a urine sample and have blood drawn for lab work.

Your provider will also ask you some questions to make sure you can fulfill the job requirements of a commercial driver, such as your ability to sit comfortably for long periods, your sleep quality, and some questions concerning your mental health.

It is important to note that this service is NOT the same as getting your annual physical. You should still present to your primary care provider each year so you can discuss with them your long term health goals and preventative health screenings and services.

What is required to pass a DOT physical?

An existing health condition won’t stop you from qualifying for a CDL unless the condition could interfere with your ability to safely operate a commercial vehicle. If you are color blind or you have diabetes that must be controlled with insulin injections, you aren’t eligible for a CDL.

The primary requirements to pass a DOT CDL exam include:

• 20/40 correctable vision in both eyes (corrective lenses are permitted)
• Ability to hear a forced whisper at a minimum distance of five feet
• Maximum blood pressure of 160/100 (Use of prescription medication to control blood pressure is allowed)
• Blood sugar of 200 mg/dL or less

If you have a cardiovascular condition, you must pass a stress test, and you’ll need a note from your personal physician stating that you can safely drive a commercial motor vehicle.

How often should I have an exam to maintain my CDL?

Once you’ve passed your CDL physical, it is valid for 12-24 months, depending on your chronic health issues. If your provider determines you have a medical condition that could worsen before your next exam, you will be required to have your next examination at an earlier date to maintain your commercial driver’s license.
