Do I Need to Take a DOT Physical?
If you are planning on operating a commercial motor vehicle (CMV), you will need to complete a DOT physical. This includes all CDL classes:
- CDL Class A
- CDL Class B
- CDL Class C
What is on the DOT Physical Exam?
You will be asked some questions about your medical history that could include:
- Past surgeries
- Current medication
- Previous health problems
- Tobacco, alcohol, or drug use
- Any issues you may be currently having
In addition to your medical history, you will also have a hands-on examination. The hands-on portion will evaluate the following:
- Blood pressure
- Lungs and chest
- Extremities and joints
- Nervous system
- Circulatory system
This exam is meant to serve as a classic physical exam. While there are some aspects that may differ from your normal physical exam, this is what you should expect.
In addition to the above, you will also have a urinalysis. This will check your protein, blood, sugar, and other things to see if you have any other medical problems. Your examiner may order other tests if they think it is necessary.
If you are curious about what other steps need to be taken to get your CDL, view our complete guide on how to get a CDL.
Is there a Drug Test on the DOT Physical Exam?
You will not be tested for drugs on the DOT physical exam. You will have to give urine as part of the urinalysis, but this is used to screen for health problems and not drugs.
If your company does require a pre-employment drug test, they may request that you have your drug screening done during this exam.
Where Do I Get a DOT Physical?
You can get a DOT physical by any health care professional who is certified by the FMCSA. Some examples of certified individuals would include:
- Doctors (MD or DO)
- Physician Assistant (PA)
- Chiropractor Doctor (DC)
- Advanced Practice Nurses (APN)

List of Conditions That Disqualify You From Getting a DOT Card
Any condition that interferes with your ability to safely operate a commercial motor vehicle will disqualify you. Some conditions could include:
- Severe vision loss
- Severe hearing loss
- Various heart conditions
- Kidney disease
- Use of illegal substances
The medical examiner will have the final say. If they think a condition you have makes you unfit to operate a commercial motor vehicle, you will not pass your DOT physical.
How To Prepare For a DOT Physical
You should not have to do much to prepare for this exam. This should be treated like your annual physical exam that you get at the doctor’s office.
Some things you should have or keep in mind include:
- List of medications you take
- List of doctors you use
- Have your glasses, contacts, or hearing aids with you on the day of your exam
- If you have had any previous medical conditions or emergencies (heart issues, strokes, seizures, etc..), have a letter from your doctor explaining that you are fit to drive.

How Long is a DOT Physical Exam Good For?
A DOT physical exam is good for 24 months according to the FMCSA. After 24 months, you will need to get another exam.
Your medical examiner may issue a medical examiner’s certificate which would be good for less than 24 months. This would be issued if the examiner wants to monitor a condition.
