Very few health conditions permanently disqualify a commercial driver. Most “failures” at a DOT physical are really short-term certificates or a request for more paperwork. The firm stops are a current epilepsy diagnosis, use of a Schedule I drug, current alcoholism, and vision or hearing that cannot meet federal minimums even with correction. Blood pressure, insulin-treated diabetes and sleep apnea usually mean a shorter card or extra records, not a lost career.
Key Takeaways
- Federal rules in 49 CFR 391.41 list the conditions a medical examiner must check, and most can be managed with treatment and documentation.
- Blood pressure of 180/110 or higher means no card until readings drop to 140/90 or lower.
- Drivers who use insulin can qualify if their treating clinician completes the FMCSA ITDM form within 45 days of the exam.
- Bring medication lists, specialist notes and CPAP compliance reports to avoid a “determination pending” result.

What Health Conditions Disqualify You From a DOT Physical?
The Federal Motor Carrier Safety Administration (FMCSA) sets the physical qualification standards in 49 CFR 391.41. A driver can be found not qualified for epilepsy, Schedule I drug use, current alcoholism, or vision and hearing below the minimums. Other conditions, such as heart disease or diabetes, depend on how well they are controlled.
The rule covers more ground than most drivers expect. It asks the medical examiner to look at limbs, heart and lung function, blood pressure, nervous system disorders, mental health, vision, hearing and substance use. A diagnosis by itself rarely ends the exam. What matters is whether the condition is likely to interfere with the ability to drive a commercial vehicle safely.
That is why the same diagnosis can lead to different outcomes for two drivers. One driver with heart disease brings a cardiologist’s letter and a recent stress test and walks out with a card. Another driver with the same history and no records may be told to come back with documentation. Getting organized before you arrive is the single most useful thing you can do, and it is part of how our occupational health team works with local drivers.
The table below sorts the most common concerns by how they usually play out.
| Condition | Usual outcome | What helps you qualify |
|---|---|---|
| Epilepsy (current diagnosis) | Not qualified | FMCSA guidance suggests 10 years seizure-free and off medication |
| Schedule I drug use | Not qualified | No medical exception |
| Current alcoholism | Not qualified | Documented remission may allow certification |
| High blood pressure | Shorter card or temporary hold | Treatment and readings at or below 140/90 |
| Insulin-treated diabetes | Card up to 12 months | ITDM Assessment Form from your treating clinician |
| Sleep apnea | Examiner’s decision | CPAP use and compliance data |
| Vision below 20/40 | Not qualified without correction | Glasses, contacts or the alternative vision standard |
How High Can Your Blood Pressure Be for a DOT Physical?
Blood pressure at or below 140/90 qualifies a driver for a standard card of up to two years. FMCSA’s medical advisory criteria recommend shorter certifications as readings climb, and a reading of 180/110 or higher means the driver should not be certified until it comes down.
Blood pressure is the most common reason drivers leave with a one-year card instead of a two-year card. The guidance breaks hypertension into three stages.
| Reading | Stage | Recommended certification |
|---|---|---|
| 140/90 or lower | Normal for DOT purposes | Up to 24 months |
| 140–159 / 90–99 | Stage 1 | 1 year |
| 160–179 / 100–109 | Stage 2 | One-time 3-month card; 1 year if you get to 140/90 or lower |
| 180/110 or higher | Stage 3 | Not qualified until 140/90 or lower, then 6-month cards |
A few simple steps help on exam day. Take your blood pressure medication as prescribed, including the morning of the exam. Skip energy drinks, nicotine and extra coffee beforehand. If you get anxious in medical offices, tell the examiner, since a second reading after you settle can come back lower. If your numbers have been high at home, see a doctor before your card expires rather than after. Our primary care team can adjust treatment and track your readings ahead of the exam.
Can You Pass a DOT Physical With Diabetes?
Yes. Diabetes controlled with diet or oral medication is not singled out as a disqualifier in the federal rule. Drivers who use insulin can also qualify under 49 CFR 391.46, as long as their treating clinician completes the Insulin-Treated Diabetes Mellitus Assessment Form (MCSA-5870) within 45 days of the DOT exam.
Before 2018, insulin users usually needed a federal exemption to drive commercially. That changed when FMCSA created the ITDM pathway. Here is how it works in practice:
- Your treating clinician, the person who manages your diabetes, fills out form MCSA-5870.
- The form confirms you have a stable insulin regimen and are properly managing your diabetes.
- You bring the signed form to the certified medical examiner, who must receive it within 45 days of signing.
- If you qualify, your medical card lasts no more than 12 months.
The treating clinician also looks for severe low blood sugar episodes. A recent episode that caused loss of consciousness or required help from another person can delay certification. Diabetes-related problems with vision, nerves or kidneys are checked separately, so a recent eye exam and current A1C result are worth bringing along. If you need updated bloodwork, our lab tests and screenings can usually be done the same week.
Does Sleep Apnea Disqualify You From a DOT Physical?
Not by itself. FMCSA says its rules do not specifically address obstructive sleep apnea. According to the agency’s sleep apnea guidance, only moderate-to-severe sleep apnea that interferes with safe driving is a problem, and the medical examiner decides whether to certify, refer the driver for testing or issue a shorter card.
Examiners often screen for sleep apnea using body mass index, neck size, high blood pressure and reports of daytime sleepiness or loud snoring. Fleet managers can find more on screening programs in our employer guide. Meeting some of these does not mean you have sleep apnea. It may mean the examiner wants a sleep study before issuing a full-length card.
If you already use CPAP, the most helpful thing to bring is a compliance report from your machine or supplier. Most examiners look for regular nightly use over the prior months. A driver who has a diagnosis but no proof of treatment is more likely to leave with a short card or a pending result.

What Vision and Hearing Do You Need to Pass?
You need at least 20/40 vision in each eye and in both eyes together, with or without glasses or contacts, plus a 70-degree field of vision in each eye and the ability to recognize red, green and amber. For hearing, you must hear a forced whisper at five feet or pass an audiometric test, with or without a hearing aid.
Glasses and contacts are fine, but if you need them to pass, your card will note that you must wear them while driving. Drivers who cannot meet the standard in one eye may still qualify under the alternative vision standard, which requires an evaluation by an ophthalmologist or optometrist on form MCSA-5871 before the DOT exam.
For hearing, the whisper test is done first. If you cannot hear the whisper, the examiner can use an audiometer. The hearing loss in your better ear cannot average more than 40 decibels at 500, 1,000 and 2,000 Hz. Hearing aids are allowed, but bring them and fresh batteries to the exam. Your card will then require you to wear them while driving.
Vision and hearing problems that start between exams are worth catching early. A quick check during a routine physical can tell you if you are close to the line well before your medical card comes up for renewal.
Will Medications or a Positive Drug Test Disqualify You?
Using a Schedule I drug disqualifies a driver, with no medical exception. Other prescribed medications are allowed when a licensed practitioner who knows your job prescribes them and advises that they will not affect safe driving. Some, including certain opioids, sleep aids and seizure medications, can still lead the examiner to hold or limit certification.
Bring a complete list of everything you take, including over-the-counter sleep aids and allergy medications. The examiner looks at what the drug does, not just its name. A stable dose that causes no drowsiness is treated very differently from a new prescription with sedating side effects.
Marijuana deserves a direct answer. The federal Office of Drug and Alcohol Policy and Compliance has stated in its medical marijuana notice that a state medical marijuana recommendation is not a valid medical explanation for a positive DOT drug test. Ohio law allowing marijuana use does not change federal testing rules for commercial drivers.
Drug testing is a separate step from the physical itself, though many drivers handle both on the same visit. Health Express offers DOT and non-DOT drug screening for drivers and employers across Northeast Ohio.
What Should You Bring to Avoid a Delayed DOT Card?
Bring a photo ID, your glasses or hearing aids, a full medication list and records for any ongoing condition. Drivers with diabetes, heart disease, sleep apnea or a past seizure should bring specialist notes, test results or compliance reports. Missing records are the most common reason an exam ends with “determination pending.”
A pending result is not a failure. It means the examiner needs more information, and you usually have up to 45 days to provide it. Use this checklist to avoid that delay:
| If you have… | Bring this |
|---|---|
| High blood pressure | Medication list and recent home readings |
| Insulin-treated diabetes | Completed MCSA-5870 form, recent A1C |
| Sleep apnea | CPAP compliance report and sleep study results |
| Heart condition or stent | Cardiologist letter, recent stress test or echocardiogram |
| Past seizure or stroke | Neurologist letter with dates and current medications |
| Vision in one eye only | Completed MCSA-5871 vision evaluation form |
Fill out the driver section of the medical examination report honestly. Leaving out a known condition can lead to the card being voided later, which causes far more trouble than disclosing it up front. If you are an owner-operator or run a small fleet, our article on occupational health services covers how to keep every driver’s card current.
Frequently Asked Questions
Can you fail a DOT physical for high blood pressure?
You can be temporarily disqualified if your blood pressure reaches 180/110 or higher. FMCSA guidance says you should not be certified until it drops to 140/90 or lower. Lower stages of hypertension usually lead to a shorter medical card instead of a failure.
How long is a DOT medical card good for?
A standard DOT medical card is valid for up to 24 months. The medical examiner can issue a shorter card, such as one year, six months or three months, when a condition like high blood pressure or insulin-treated diabetes needs closer monitoring between exams.
Can you drive a commercial vehicle if you take insulin?
Yes. Since 2018, drivers who use insulin can qualify without a federal exemption. Your treating clinician must complete form MCSA-5870 within 45 days of your DOT exam. If you qualify, the medical examiner can issue a card lasting up to 12 months.
Does sleep apnea mean you will fail your DOT physical?
No. FMCSA rules do not specifically disqualify drivers with sleep apnea. The examiner decides whether your condition interferes with safe driving. Drivers who use CPAP regularly and bring compliance reports often receive a card, sometimes for a shorter period while treatment continues.
What happens if you fail a DOT physical?
If you are found not qualified, you cannot drive a commercial vehicle until you are certified. You can treat the condition and return for a new exam. Many drivers qualify later once blood pressure, blood sugar or another issue is brought under control and documented.
Can you pass a DOT physical with a history of seizures?
It depends on the history. FMCSA guidance suggests drivers with epilepsy be seizure-free and off seizure medication for 10 years. A single unprovoked seizure that was not epilepsy carries a suggested five-year waiting period. A neurologist’s letter helps the examiner decide.
Does a medical marijuana card help with a DOT drug test?
No. The Department of Transportation does not accept a state medical marijuana recommendation as a valid medical explanation for a positive DOT drug test. A positive result is reported as a violation, even when marijuana use is legal under Ohio state law.
What does determination pending mean on a DOT physical?
Determination pending means the medical examiner needs more information before deciding. You may be asked for specialist notes, test results or a compliance report. You generally have up to 45 days to provide them, and your existing card stays valid until it expires.
How much does a DOT physical cost at Health Express?
A DOT physical costs $95 for self-pay patients at Health Express Urgent Care. Walk-ins are welcome, and many employers cover the cost for their drivers. Ask your employer whether they have an account before your visit so you are not billed directly.
Do you need an appointment for a DOT physical?
No appointment is needed at Health Express Urgent Care. Walk-ins are welcome at clinics across Northeast Ohio, seven days a week. Arriving with your medication list, glasses or hearing aids and any specialist records helps the exam move quickly and avoids delays.
The Bottom Line
Most DOT physical problems come down to control and paperwork. Drivers with high blood pressure, diabetes or sleep apnea keep driving every day because they treat the condition and bring proof. If you are unsure where you stand, get checked early and give yourself time to fix what you can. Health Express Urgent Care has certified medical examiners at clinics across Northeast Ohio, and results are reported to the national registry for you.
