A DOT physical requires more paperwork than most people expect. Beyond a valid photo ID and your basic health information, you’ll need documentation for any medical conditions, a list of every medication you take, and any corrective devices like glasses or hearing aids. Showing up without the right items can mean a wasted trip, a shorter certification period, or an outright disqualification that could have been avoided.
What Every Driver Should Bring
Regardless of your health history, there’s a baseline set of items you need at every DOT physical:
- Valid photo ID: A driver’s license, passport, or state-issued ID.
- Complete medication list: The medical examiner will review every prescription, over-the-counter medication, and supplement you take. Write down the name, dosage, and how often you take each one. Include the name of the prescribing doctor for each prescription medication.
- Glasses or contact lenses: If you wear corrective lenses for driving, bring them. You’ll need to pass a vision test, and your medical certificate will note whether corrective lenses are required.
- Hearing aids: If you use them, wear them to the exam. Keep in mind that standard office hearing tests can’t always evaluate someone wearing a hearing aid, so you may be referred for specialized testing.
- Your medical history: You’ll fill out the medical history section of the Medical Examination Report Form (MCSA-5875) as part of the visit. Having your information organized ahead of time, including past surgeries, hospitalizations, and chronic conditions, speeds this up considerably.
If your employer gave you any specific forms or a company code, bring those too.
Blood Pressure: Know Your Numbers
Blood pressure is one of the most common reasons drivers get a shorter certification or fail entirely. The thresholds are strict:
- Below 140/90: Full two-year certification.
- 140-159/90-99 (Stage 1): One-year certification.
- 160-179/100-109 (Stage 2): A one-time, three-month temporary certification. If your pressure drops below 140/90 within those three months, you can get a one-year certificate.
- Above 180/110 (Stage 3): Disqualified. Once it comes down below 140/90, you can be certified at six-month intervals.
If you take blood pressure medication, take it as usual on exam day. Don’t skip it hoping for a “natural” reading. The examiner expects medicated readings and wants to see that your treatment is working.
What to Bring for Sleep Apnea
If you’ve been diagnosed with sleep apnea and use a CPAP or similar device, bring a compliance report downloaded from your machine. This report needs to show at least 90 days of usage data and should be no more than 30 days old. Some examiners request a full year of data if it’s available.
The usage standard is four hours per night, at least 70 percent of the time. If your data falls short of that, expect questions or a potential delay in certification. Many CPAP machines have apps or SD cards that make pulling this data straightforward. Call your equipment provider if you’re unsure how to generate the report.
What to Bring for Diabetes
Drivers who manage diabetes with diet or oral medication generally don’t need extra paperwork beyond their medication list. Insulin-treated diabetes is a different story.
If you use insulin, you need the Insulin-Treated Diabetes Mellitus Assessment Form (MCSA-5870), completed by your treating doctor. This form confirms that your insulin regimen is stable and your diabetes is properly controlled. It must be completed within 45 days of your DOT physical, so schedule your doctor’s appointment first and your DOT exam second. Showing up without this form means the examiner cannot certify you.
What to Bring for Heart Conditions
Drivers with a history of heart attack, stents, bypass surgery, or a pacemaker need clearance documentation from a cardiologist. The specifics depend on your situation:
- After a heart attack: You can be recertified two months after the event. You’ll need a cardiologist’s written approval, an echocardiogram showing adequate heart function, and a stress test performed four to six weeks post-heart attack. The stress test must be repeated at least every two years.
- After a stent (elective): Return to work can happen as soon as one week after an uncomplicated procedure. You’ll need the treating cardiologist’s approval, confirmation that you’re symptom-free, and a stress test three to six months after the procedure, then at least every other year.
- Pacemaker: Certification is possible one month after implantation with documented correct function from a pacemaker center. Annual pacemaker checks are required going forward.
In all of these cases, bring the actual letters and test results. A verbal “my cardiologist says I’m fine” won’t work. The medical examiner needs written documentation to certify you.
Medications That Need Extra Documentation
The examiner reviews every medication for its potential to affect your ability to safely operate a commercial vehicle. Most common prescriptions won’t cause problems, but certain categories get extra scrutiny: opioids, benzodiazepines, muscle relaxants, sedating antihistamines, stimulants, and anti-seizure medications.
If you take anything that could raise a red flag, ask your prescribing doctor to write a letter stating that the medication does not impair your ability to drive a commercial vehicle. The examiner can request this letter, and having it ready saves you a return visit. The letter should include the medication name, dosage, how long you’ve been on it, and the doctor’s professional opinion on your fitness to drive.
Seizure and Neurological History
A history of seizures requires a formal exemption process through the FMCSA, which involves a separate application package. If you’ve already received a seizure exemption, bring your current exemption letter and any required medical release forms. If you’re applying for the first time, you’ll need to submit the Federal Seizure Exemption Application before your DOT physical, not at the appointment itself.
For other neurological conditions like stroke, bring clearance documentation from your neurologist, including the date of the event, current symptoms (or lack of them), and any relevant imaging or test results.
Practical Tips for Exam Day
Give yourself a urine sample window. You’ll need to provide one at the exam for sugar and protein testing (this is not a drug test). Drink water beforehand so you’re not stuck waiting. Avoid excessive caffeine before the appointment, as it can temporarily raise your blood pressure.
Wear your corrective lenses. If you normally drive with glasses, don’t leave them in the car thinking you’ll pass without them. If you fail the vision screening, your certification will be delayed until you can demonstrate adequate vision.
Organize your paperwork in a folder. Fumbling through a stack of random papers wastes your time and the examiner’s. Label specialist letters and test results clearly. If you have multiple conditions requiring documentation, a simple checklist for yourself can prevent the sinking feeling of realizing you left something at home.
