Where to find a CDL medical examiner in your area
A CDL medical exam (also called a DOT physical) must be performed by a doctor on the Federal Motor Carrier Safety Administration's (FMCSA) National Registry of Certified Medical Examiners. You cannot use your regular doctor unless they are on this registry. The FMCSA maintains a searchable database at their website where you enter your state and city to see which certified examiners operate near you.
Most certified examiners work in primary care clinics, occupational health centers, or standalone urgent care facilities. Some are independent practitioners. The database shows their address, phone number, and whether they currently accept new patients. Call ahead before visiting — many examiners book weeks in advance, especially in rural areas where few doctors hold certification.
If the database shows no examiners within a reasonable distance, contact your state's Department of Transportation or your local trucking association. They often maintain their own lists and can direct you to the nearest option, even if it requires traveling to another town.
Key Takeaways
- Only doctors on the FMCSA's National Registry of Certified Medical Examiners can perform your CDL medical exam, and you can search for them by location on the FMCSA website.
- The exam typically costs between $75 and $200 depending on your location and the clinic, and most examiners require payment at the time of your visit.
- You will need to bring your current driver's license, proof of citizenship or legal residency, and a list of any medications you take or medical conditions you have.
- The exam takes 30 to 60 minutes and results are usually available the same day or within a few business days.
- If you fail the exam, you can retest with a different examiner or work with your doctor to address the medical issue and try again.
What to bring to your CDL medical exam appointment
Bring your current driver's license or state ID as proof of identity. You will also need proof of citizenship or legal residency — a passport, birth certificate, or naturalization papers all work. The examiner will verify this information before proceeding.
Write down all medications you currently take, including over-the-counter drugs and supplements. If you have a list from your regular doctor, bring that. Also note any medical conditions you have been treated for in the past five years, such as diabetes, high blood pressure, heart disease, or sleep apnea. The examiner will ask detailed questions about these, so having the information ready speeds up the process.
Wear comfortable, loose-fitting clothing that allows the examiner to check your blood pressure and listen to your heart and lungs. If you wear glasses or contacts, bring them. Some examiners ask you to fast (not eat) for a few hours before the exam if they plan to draw blood, so call ahead to confirm whether fasting is required.
How the CDL medical exam works and what gets tested
The exam begins with a review of your medical history. The examiner will ask about past injuries, surgeries, hospitalizations, and any ongoing treatment. They will also ask whether you have ever been diagnosed with certain conditions — diabetes, epilepsy, heart problems, or sleep disorders — because these can affect your ability to drive safely.
The physical portion includes blood pressure measurement, vision and hearing tests, and a check of your reflexes and coordination. The examiner listens to your heart and lungs with a stethoscope and may press on your abdomen to check for problems. They will also ask you to walk in a straight line and perform straightforward balance tests. Some examiners order blood work or a urinalysis, though this is not required for every exam.
The entire appointment usually takes 30 to 60 minutes. At the end, the examiner tells you whether you passed, failed, or passed with restrictions. If you pass, they issue a Medical Examiner's Certificate (also called a DOT medical card) valid for two years. If you fail or receive restrictions, they explain which medical issue caused the decision and whether you can retest after treatment.
Cost and payment for CDL medical exams
CDL medical exams cost between $75 and $200 depending on where you live and which clinic you visit. Urban areas and established occupational health centers tend to charge toward the higher end. Rural clinics or independent practitioners may charge less. Call the examiner's office before scheduling to confirm the exact price.
Most examiners require payment at the time of your visit. Some accept cash, credit cards, or checks. A few may bill your insurance, though many do not because the exam is not considered a standard medical service. Check with the clinic about their payment methods when you call to schedule.
If cost is a barrier, some trucking companies or training programs cover the exam fee for their employees or students. If you are enrolled in a CDL training program, ask whether they have a partnership with an examiner or whether they reimburse the cost.
What happens if you fail or get restricted results
If the examiner finds a medical condition that disqualifies you, they will explain which condition caused the failure and whether it is temporary or permanent. Some conditions — like uncontrolled high blood pressure or untreated diabetes — can sometimes be managed with medication or lifestyle changes, allowing you to retest after treatment.
Other conditions, such as certain seizure disorders or severe vision problems, may permanently disqualify you from holding a CDL. In those cases, the examiner can explain your options, which might include pursuing a waiver from your state's Department of Transportation or exploring non-driving roles in the trucking industry.
If you receive a restricted certificate, you can still drive but only under certain conditions — for example, only during daylight hours, only within a certain distance from home, or only with corrective lenses. The restrictions appear on your Medical Examiner's Certificate, and law enforcement can see them during a traffic stop.
Scheduling your exam and what to expect on the day
Once you find an examiner, call their office to schedule. Many examiners book several weeks ahead, so do not wait until you need the certificate urgently. When you call, confirm the cost, ask whether fasting is required, and ask what time to arrive (most ask you to come 10 to 15 minutes early).
On the day of your exam, arrive on time with all required documents. Bring a list of your medications and medical history if you have not already submitted it. Plan to spend 45 minutes to an hour at the clinic, even if the exam itself takes only 30 minutes, because check-in and paperwork add time.
After the exam, ask when you will receive your results. Some examiners hand you the Medical Examiner's Certificate the same day. Others mail it within a few business days. If you pass, keep the certificate in a safe place — you will need to show it to your employer or to law enforcement if stopped while driving commercially.
Retesting after a failed exam
If you fail the exam, you can retest with a different examiner if you wish, though the result will likely be the same unless you have treated the underlying medical issue. Before retesting, work with your regular doctor to address the condition that caused the failure. For example, if your blood pressure was too high, your doctor can adjust your medication and monitor your readings over several weeks before you retest.
Some states allow you to retest when ready after failing. Others require you to wait a certain number of days. Check your state's rules before scheduling a second exam. Keep records of any treatment or medical visits related to the condition that caused the failure — examiners often want to see this documentation before reconsidering your case.
If you believe the examiner made an error, you can request a second opinion from another certified examiner. The FMCSA does not have a formal appeal process, but a different examiner may reach a different conclusion based on their review of your medical history and physical exam.
Frequently Asked Questions
How long does a CDL medical certificate last?
A Medical Examiner's Certificate is valid for two years from the date of issue. After two years, you must schedule another exam to renew it. Some examiners send reminder notices when your certificate is about to expire, but it is your responsibility to schedule the renewal before the expiration date.
Can I use my regular doctor for a CDL medical exam?
Only if your regular doctor is certified by the FMCSA and appears on the National Registry. Most primary care doctors are not certified. You can ask your doctor whether they hold this certification, or you can search the FMCSA database to see if they are listed.
What medical conditions automatically disqualify you from a CDL?
Conditions that significantly impair your ability to operate a large vehicle safely — such as uncontrolled seizures, severe vision loss, or certain heart conditions — can disqualify you. However, many conditions are manageable with treatment or restrictions. The examiner will explain which specific condition caused your result and whether treatment or a waiver might change the outcome.
Do I need a CDL medical exam before I take the written CDL test?
Requirements vary by state. Some states require the medical exam before you take any CDL test. Others allow you to take the written test first and schedule the medical exam later. Check your state's Department of Transportation website or call your local DMV to confirm the order of steps in your state.
What if I cannot find a certified examiner near me?
Contact your state's Department of Transportation or a local trucking association — they can direct you to the nearest examiner, even if it requires traveling to another town. Some examiners also offer telehealth consultations for the medical history portion, though the physical exam must be done in person.
