A DOT physical is a thorough medical exam that helps make sure you can safely drive commercial motor vehicles (CMVs). The U.S. government establishes certain health standards that all CMV drivers must meet. If you meet these standards, you receive a medical examiner’s certificate that’s typically valid for two years.

A U.S. Department of Transportation (DOT) physical is a medical exam that verifies you meet certain standards to drive a commercial motor vehicle (CMV). Examples of CMVs include semi-trucks, buses and vehicles carrying hazardous materials. Driving these vehicles is a big responsibility. Employers must make sure you’re able to take on this task safely.

For example, you must be able to hear sounds around you, see road signs and stay awake. Various health conditions or medications may affect your ability to do these things. Or some conditions may put you at risk for medical emergencies that, if they happen on the road, place you and others in danger.
On a national level, the Department of Transportation decides who needs a DOT physical. In general, they require it for anyone who drives a CMV across state lines. Individual states also have rules and regulations for who needs a DOT physical. You may need one if you drive a CMV within state boundaries.
You’ll typically need a DOT physical every two years to stay qualified to drive a CMV. You may need exams more frequently based on your medical history. If you meet the Department of Transportation’s medical standards, you’ll receive your medical examiner’s certificate. People commonly call this your medical card.
Certified medical examiners perform DOT physicals. These are healthcare providers who complete additional training in determining whether someone can safely drive a CMV. They understand the physical and mental demands this type of task requires.
Medical examiners must pass a certification test and do refresher training every five years to maintain their status. They must also take a certification test every 10 years. You can feel confident in their ability to evaluate your health in the context of driving a CMV.

You can find a medical examiner near you by searching the National Registry of Certified Medical Examiners. This online tool allows you to search by city and state or by zip code. Once you select a medical examiner, you can call to schedule your DOT physical appointment.
It’s a good idea to contact your medical examiner’s office before your appointment and ask what you should prepare or bring with you. In general, you should:
Here are some items you’ll need for a few specific, common medical conditions:
Knowing in advance what you need to bring can help prevent delays in certification.
You must meet certain vision standards to drive a CMV. If your vision doesn’t meet those standards, you’ll need to submit a vision evaluation form at least once a year.
This is a form that your ophthalmologist or optometrist fills out. They provide details about your vision and eye health and comment on your ability to safely drive a CMV. Your ophthalmologist or optometrist should complete the form no more than 45 days before your DOT physical exam.
You need to submit this form if you take insulin to manage diabetes. The healthcare provider that helps you manage diabetes fills out the form. They’ll provide information on many aspects of your health, including:

Your provider will sign and date the form and give it to you to take to your DOT physical exam. This should happen no more than 45 days before your DOT exam date.
This form explains the medications you’re taking. Medical examiners request you submit this form when they need to verify your medications won’t affect your driving ability. Therefore, you may not know you need the form until after your exam. For example, the examiner might tell you they can’t make a final decision about your certification until they get more information from your healthcare provider.
The medication form includes spaces for your provider to share details like the specific medications you’re taking, the dosages and what they’re treating. Your provider should fill out the form and give it back to you to take to a follow-up DOT exam appointment.
A DOT physical is a thorough medical exam that evaluates many aspects of your health. Your medical examiner will explain each step of the process. They’ll begin by discussing your health history. This is the information you provide on the first two pages of your medical examination report form. Your examiner may ask you about some of your responses to get further information.

Then, your examiner will:
All these steps allow your examiner to get a sense of your overall health. They’ll look for any signs of a health condition that may affect your ability to drive a CMV. Try to relax during this process. You might feel worried or anxious about the outcome. But keep in mind that the purpose of this exam is to keep you and others safe.
Your examiner will tell you the results of the exam and explain what you need to do next.
In some cases, you’ll need to visit a healthcare provider for further testing, treatment or paperwork. This may happen if your examiner finds an issue that needs attention. You may still qualify for your medical certificate, but only after you take care of the medical issue or documentation. In other cases, a health condition may disqualify you from receiving a medical certificate. Your examiner will explain the reasons and answer all your questions.
