Key Takeaways
- Use only FMCSA-certified medical examiners listed on the National Registry.
- Vision, hearing, and blood pressure are frequent make-or-break checks.
- Disclose medications - surprises at the exam waste time and money.
- Card length can be shortened for monitored conditions.
- Keep proof of medical certification available for roadside and hiring.
- Schedule renewals early - expired cards park trucks.

O TruckingDOT Physical Requirements 2026: Medical Card Rules for CDL Drivers
Who Needs a DOT Physical
Interstate CMV drivers and many intrastate CDL holders need a valid medical certificate. Carriers verify it in the DQF - see DOT audit prep.
What the Exam Covers
| Area | What examiners look for | Tip |
|---|---|---|
| Vision | Acuity and field standards | Bring corrective lenses |
| Hearing | Forced whisper / audiometric | Disclose aids |
| BP / pulse | Hypertension stages | Rest before the exam |
| History / meds | Disqualifying conditions | Bring a med list |
| Urinalysis | Sugar / protein screens | Hydrate normally |
Registry only
How Long Is a DOT Medical Card Good?
Many drivers receive up to a two-year card. Examiners may issue shorter cards when conditions need monitoring (for example blood pressure follow-up). Do not wait until the week of expiration.
How to Prepare
Sleep and meds
Take prescribed meds as directed; bring bottles/list.
BP strategy
Avoid caffeine/salt binges right before the exam.
Paperwork
ID, glasses, prior cards, specialist letters if any.
Honesty
Undisclosed conditions found later create bigger problems.
Renew 60 days early
The Standard Is 49 CFR 391.41, Not a Clinic Poster
A DOT physical is the medical exam in 49 CFR 391 Subpart E. The examiner decides whether you meet 391.41(b). The certificate is evidence of that decision. It is not a general checkup, and a primary-care doctor who is not listed on FMCSA's National Registry of Certified Medical Examiners cannot issue it. Look the examiner up on the registry before you pay. A certificate from someone who is not listed does not satisfy the rule, no matter how thorough the visit felt.
Who must have it: drivers of commercial motor vehicles in interstate commerce who are subject to part 391, which includes CDL holders and many non-CDL drivers of vehicles that meet the weight, passenger, or placarded-hazmat tests. Intrastate rules can be stricter or can adopt the federal standard. Ask your state if you never leave it. A carrier that dispatches you across a state line does not get to waive the exam because the truck is "local most days."
The Tests Drivers Fail or Fear
| Item | Federal floor | What changes the card length |
|---|---|---|
| Vision | 391.41(b)(10): at least 20/40 in each eye and both together, with or without correction; field of vision at least 70 degrees in the horizontal meridian in each eye; able to recognize red, green, and amber. | A prescription you do not wear to the exam. Bring the glasses you drive with. |
| Hearing | 391.41(b)(11): forced whisper at not less than 5 feet in the better ear, with or without a hearing aid, or an average loss no greater than 40 decibels at 500, 1,000, and 2,000 Hz. | A hearing aid you use on the road and forgot to bring. |
| Blood pressure | Examiner guidance treats under 140/90 as eligible for up to 2 years. Stage 1, 140–159 over 90–99, is often a 1-year card. Stage 2, 160–179 over 100–109, is often a one-time 3-month card. At or above 180/110 is disqualifying until it is treated. | The examiner issues the certificate. Coffee, a full bladder, and a missed medication change the reading. They do not change the rule. |
| Diabetes treated with insulin | The old federal exemption program is gone. 391.46 lets the examiner certify an insulin-treated driver after the evaluation the section requires. It is not an automatic pass and not an automatic fail. | Bring the treating clinician's paperwork the examiner asked for. Showing up without it wastes the visit. |
The maximum certificate is 24 months under 391.45. Examiners shorten it for conditions they want to see again: hypertension, a recent cardiac event, sleep apnea that is not yet documented as treated, vision that just meets the line. A one-year card is still a pass. A three-month card is a pass with a deadline. Mark the deadline. The medical card that expires on a Thursday does not cover the load you picked up on Wednesday night if the break runs past midnight into Friday and your state has already dropped you.
Where the Card Has to Live in 2026
FMCSA's Medical Examiner's Certification Integration required states to post CDL medical certification on the driving record, with a compliance date of June 23, 2025. CDL and CLP holders should confirm the exam posted to the state record the license is tied to. Do not assume the clinic's upload worked because they said it would. A non-CDL driver who still needs the exam carries the paper medical examiner's certificate. Roadside inspectors on a Level I or Level III still check medical qualification. An expired record is a driver violation even when the brakes are perfect. The inspection context is on the Level 1 checklist.
Skill Performance Evaluation certificates are a separate FMCSA path for specific limb impairments. They are not something a clinic invents. If you have one, bring it. If an examiner tells you that you need one, follow that instruction instead of shopping for a shorter exam. Employers must keep the medical certificate in the driver qualification file when the rules require it. Your copy and their copy can both be "the" copy until the state record is the system of record for your CDL. Ask the carrier which one they verified at hire.
Nothing here clears you to drive. The certified examiner does, for a stated number of months, against 391.41. If you disagree with a disqualification, the appeal is the one your state and FMCSA publish, not a second unofficial exam you hope no one notices. Schedule the renewal before the card dies, not the morning the dispatcher finds out.
Medications are part of the exam even when your blood pressure is fine. The examiner asks what you take because some drugs, and some conditions behind them, are disqualifying or need a shorter card. Bring the bottles or a current list with doses. A driver who stops a blood-pressure pill for two days to "test clean" is the driver who strokes out on a grade, and the reading at the clinic will not match the reading on the road. Sleep apnea treatment belongs in the same stack: if you use a CPAP, bring the compliance report the examiner asked for. Guessing that you use it "most nights" is not data.
Seizure history, insulin, and a missing limb are the cases where rumors do the most damage. The regulation and the examiner's guidance are narrower than a forum post. Some histories disqualify you. Some are certifiable with documentation or with a Skill Performance Evaluation. Do not take a driving job that requires a medical card you have not been issued, and do not hide a condition that will show up when the carrier orders a new exam at hire. The second exam will not match the first, and the carrier will keep the stricter result. Schedule renewal 45 days before expiration so a one-year card does not become a missed dispatch while you wait for a specialist letter.
