To schedule a DOT physical, find a certified medical examiner on the FMCSA’s National Registry at nationalregistry.fmcsa.dot.gov, then call or book online directly with that examiner’s office. The exam runs 30 to 45 minutes and costs roughly $75 to $150 out of pocket. Insurance rarely covers it unless your employer pays, and the fee is usually due at the time of service.
Find a Certified Medical Examiner
Your exam only counts for federal compliance if it’s performed by a medical examiner listed on the FMCSA’s National Registry of Certified Medical Examiners.1Federal Motor Carrier Safety Administration. National Registry of Certified Medical Examiners An exam from anyone else is wasted money.
Go to nationalregistry.fmcsa.dot.gov and search by zip code, city, or state. Results show each examiner’s name, credentials, and office location. Before you call to book, confirm the listing is current. Certification can lapse, and an exam from a decertified examiner won’t be accepted.2Federal Motor Carrier Safety Administration. DOT Medical Exam and Commercial Motor Vehicle Certification
Book the Appointment
Most drivers book by calling the clinic directly. Some offices also offer online scheduling through their own websites or third-party platforms. Urgent care and occupational health clinics that handle high volumes of DOT physicals often have same-day or next-day openings; smaller practices may book a week or more out.
When you call, ask three things:
- The next available appointment.
- The full cost and accepted forms of payment. Expect $75 to $150, and confirm before you show up.
- Anything specific the office wants you to bring beyond the standard items.
Confirm the date, time, and address before you hang up.
If you’re renewing, schedule well before your current certificate expires. There is no formal grace period in the federal regulations. A driver whose certificate has lapsed is not medically certified to operate a CMV.3eCFR. 49 CFR 391.45 A calendar reminder 90 days out gives you enough runway to book, gather any specialist paperwork, and submit the new certificate to your state before anything lapses.
What to Bring
Bring a government-issued photo ID and a complete list of every medication you take, including over-the-counter drugs and supplements, with dosages. If you have a chronic condition, bring documentation showing it’s under control. The examiner can’t certify what they can’t verify, and missing paperwork is one of the most common reasons drivers leave without a certificate.
If you wear corrective lenses or a hearing aid, bring them. Their use will be noted on your certificate, and you’ll need them during the exam.
How to Prepare in the Days Before
Stay hydrated, get a full night’s sleep, and cut back on caffeine, nicotine, and high-sugar foods. All three can temporarily spike blood pressure, and an elevated reading at the exam can shorten your certification period or disqualify you that day. Plenty of drivers walk in with a reading ten points higher than their actual baseline because they drank two energy drinks on the way over.
What the Exam Covers
The DOT physical evaluates whether you meet the federal physical qualification standards in 49 CFR 391.41. It is not a general wellness check. The examiner is looking specifically for conditions that could impair your ability to safely control a commercial vehicle.4Federal Motor Carrier Safety Administration. Driver Physical Qualification
Vision
You need distant visual acuity of at least 20/40 in each eye individually and in both eyes together, with or without corrective lenses. Your horizontal field of vision must be at least 70 degrees in each eye, and you must be able to distinguish standard red, green, and amber traffic signals.5Federal Motor Carrier Safety Administration. Vision and Commercial Motor Vehicle Driver Safety Drivers who don’t meet the standard in their worse eye may still qualify under an alternative vision standard that replaced the old exemption program in 2022.6Federal Motor Carrier Safety Administration. General Vision Exemption Package
Hearing
The examiner starts with a forced whisper test. You need to hear a whispered voice from at least five feet away in your better ear, with or without a hearing aid. If you can’t pass the whisper test, the examiner moves to an audiometric test, where your average hearing loss in the better ear can’t exceed 40 decibels across 500 Hz, 1,000 Hz, and 2,000 Hz.7Federal Motor Carrier Safety Administration. What Are the Hearing Requirements for CMV Drivers
Blood Pressure
Your blood pressure directly controls how long your certificate lasts:8Federal Motor Carrier Safety Administration. What Is the Effect on Driver Certification Based on FMCSA Hypertension Stages
- Below 140/90: two-year certification.
- Stage 1 (140–159 / 90–99): one-year certification.
- Stage 2 (160–179 / 100–109): one-time three-month certification. If you get below 140/90 within those three months, you can receive a one-year certificate.
- Stage 3 (180+ / 110+): disqualified. Once your blood pressure drops below 140/90, you can be certified at six-month intervals.
Urinalysis
The urine sample screens for glucose and protein levels to detect conditions like diabetes or kidney problems. It is not a drug test. DOT drug testing is a separate process governed by different regulations.9Federal Motor Carrier Safety Administration. What Substances Are Tested
General Physical Assessment
The examiner checks your eyes, ears, mouth and throat, heart, lungs, abdomen, spine, and extremities, evaluating your neurological, cardiovascular, respiratory, and musculoskeletal systems. Conditions that can lead to loss of consciousness, sudden incapacitation, or inability to control a vehicle are disqualifying if they’re not adequately treated.10eCFR. 49 CFR 391.41
Conditions That Need Paperwork Before You Book
If any of the following apply, gather the documentation before you schedule so you don’t walk into the exam empty-handed.
Insulin-treated diabetes. Your treating clinician must complete the Insulin-Treated Diabetes Mellitus Assessment Form (MCSA-5870) attesting that your insulin regimen is stable and your diabetes is properly controlled.11Federal Motor Carrier Safety Administration. Insulin-Treated Diabetes Mellitus Assessment Form MCSA-5870 The certified medical examiner must receive this form and begin your exam within 45 days of your clinician signing it. You also need at least three months of electronic blood glucose self-monitoring records. Without those records, the examiner can issue a certificate for no more than three months while you build the history. The maximum certification period for insulin-treated drivers is 12 months.12Federal Motor Carrier Safety Administration. Insulin-Treated Diabetes Mellitus Assessment Form MCSA-5870
Heart conditions. Bring a letter from your cardiologist describing your current status and treatment.
Sleep apnea. Bring a compliance report from your CPAP machine or a letter from your sleep specialist confirming treatment adherence. If the examiner suspects untreated sleep apnea based on symptoms, body mass index, or clinical evaluation, they can withhold certification until you’ve been evaluated by a sleep specialist and, if necessary, started treatment.
High blood pressure. Bring recent readings from your primary care physician showing your blood pressure is controlled.
After the Exam
If the examiner determines you meet the standards, you receive a Medical Examiner’s Certificate (MEC), Form MCSA-5876.13Federal Motor Carrier Safety Administration. Medical Examiners Certificate MEC Form MCSA-5876 Possible outcomes:
- Full two-year certification, no restrictions.
- Certification with conditions, such as wearing corrective lenses or a hearing aid while driving.
- A shortened certification period of 12, 6, or 3 months for a condition like controlled hypertension or insulin-treated diabetes.
- Temporary disqualification pending further evaluation or treatment.
- Disqualification if you don’t meet the standards and no exemption or alternative standard applies.
Getting the certificate is only half the job. CDL holders must give a copy of the new certificate to their state driver licensing agency before the current one expires.14Federal Motor Carrier Safety Administration. CDL Medical Submission method varies by state: some accept mail, some take fax or email, others require online submission or an in-person visit. Check FMCSA’s state-by-state instruction sheet or contact your state DMV.15Federal Motor Carrier Safety Administration. State-by-State Instructions for Submitting Medical Certificates for CDL Drivers to the State Agencies When you submit, your state agency will also want to know your self-certification category (interstate or intrastate, excepted or non-excepted).16Federal Motor Carrier Safety Administration. How Do I Determine Which of the 4 Categories of Commercial Motor Vehicle CMV Operation I Should Self-Certify to With My State Driver Licensing Agency SDLA
Give a copy to your employer too. Motor carriers must keep your current medical certificate in your Driver Qualification File. Keep your own copy for roadside inspections.
Don’t let the certificate lapse. Under federal regulations, your state must initiate a CDL downgrade and complete it within 60 days of your medical certification status changing to “not-certified.”17eCFR. 49 CFR 383.73 A downgrade means your CDL reverts to a non-commercial license, and depending on your state, reinstating it may require retaking the CDL skills test, not just renewing your medical certificate. Drivers on shortened 6-month or 12-month cycles need to be especially careful, because a shorter clock is easier to lose track of.
