Key takeaways
- The DOT physical standards are in 49 CFR 391.41. A medical card can last up to 24 months, or up to 12 months for insulin-treated diabetes.
- FMCSA rules do not require sleep apnea screening, but examiners look at risk factors such as BMI, neck size and high blood pressure, and treated moderate-to-severe sleep apnea does not rule out certification.
- FMCSA guidance ties blood pressure to shorter certification periods: 1 year for 140/90 to 159/99, and no certification at 180/110 or higher until it is controlled.
- Since the 2018 diabetes rule, drivers with stable, properly controlled insulin-treated diabetes can qualify with a form from their treating clinician.
- Life insurers set their own rules. Controlled, documented conditions and honest answers give you the best chance at fair coverage.
Sleep apnea, high blood pressure, diabetes and weight can affect both your DOT medical card and your life insurance, but the two decisions are separate. FMCSA's rules decide whether you can safely drive a commercial vehicle. A life insurer decides whether to cover you and what to charge. A condition that shortens your medical card does not automatically block life insurance, and passing your physical does not guarantee a policy.
This guide explains what the federal rules say about the conditions drivers ask about most, and how life insurers tend to look at the same conditions.
What health conditions does the DOT physical check?
The DOT physical checks whether you meet the standards in 49 CFR 391.41. A certified medical examiner reviews your history and examines you, then decides whether you are physically qualified.
The standards drivers run into most often:
Standard in 391.41(b) | What it covers |
|---|---|
(3) Diabetes | Insulin-treated diabetes is allowed only if you meet the rules in 391.46 |
(4) Heart | No current diagnosis of heart attack, angina or other heart disease of a kind known to cause fainting, shortness of breath, collapse or heart failure |
(5) Breathing | No respiratory problem likely to interfere with safe driving (this is where sleep apnea falls) |
(6) Blood pressure | No high blood pressure likely to interfere with safe driving |
(8) Seizures | No epilepsy or other condition likely to cause loss of consciousness |
(10) Vision | 20/40 in each eye, with or without glasses, or an alternative standard under 391.44 |
(11) Hearing | Hear a forced whisper at 5 feet in the better ear, with or without a hearing aid, or pass an audiometric test |
(12) and (13) Drugs and alcohol | No use of certain controlled substances unless properly prescribed, and no current diagnosis of alcoholism |
Under 49 CFR 391.45, most drivers must be recertified at least every 24 months. Drivers with insulin-treated diabetes must be recertified at least every 12 months. You must also be reexamined if an injury or illness has impaired your ability to do your job.
How does sleep apnea affect your medical card and life insurance?
A sleep apnea diagnosis does not automatically disqualify you from driving. FMCSA's Medical Examiner's Handbook (2024 edition, section 4.8.3.6) says that moderate-to-severe sleep apnea, if treated, does not rule out certification.
The handbook says the federal rules do not require examiners to screen for sleep apnea and do not set waiting periods, maximum certification periods or specific tests for it. Instead, examiners look at multiple risk factors, including:
- Loud snoring or witnessed pauses in breathing
- Sleepiness during your main waking hours
- Obesity or a high body mass index (BMI)
- A large neck size or small airway
- High blood pressure, heart disease, stroke or diabetes
If you have several risk factors, the examiner may recommend a sleep study. If you are diagnosed with moderate-to-severe sleep apnea, the question becomes whether your treatment is "adequate, effective, safe, and stable."
Life insurers ask a similar question for a different reason. Applications commonly ask whether you have been diagnosed with sleep apnea, how severe it is and whether you use treatment such as a CPAP machine. Records showing you use your treatment as prescribed give the insurer a clearer, more favorable picture than an untreated diagnosis. Each insurer sets its own rules.
What blood pressure do you need to pass a DOT physical?
FMCSA's handbook guidance links your blood pressure to how long your medical card lasts. These are advisory criteria that examiners apply using their own medical judgment, not hard legal cutoffs.
Blood pressure (FMCSA guidance) | Stage | What the examiner may do |
|---|---|---|
140–159 / 90–99 | Stage 1 | Certify for 1 year; recheck yearly, aiming for 140/90 or lower |
160–179 / 100–109 | Stage 2 | One-time 3-month card to start or adjust treatment; then 1 year if 140/90 or lower |
180 / 110 or higher | Stage 3 | Not qualified, even briefly, until 140/90 or lower; then 6-month cards |
The handbook also says an elevated reading should be confirmed by at least two more measurements, and that high blood pressure alone is unlikely to interfere with safe driving, though the risk rises when it has caused organ damage, especially to the blood vessels of the brain.
For life insurance, a paramedical exam usually includes blood pressure readings, and applications ask about diagnoses and medications. Insurers generally look at whether your blood pressure is controlled over time, not just one reading.
Can you drive a truck with insulin-treated diabetes?
Yes, if your diabetes is stable and properly controlled. On September 19, 2018, FMCSA published its diabetes standard final rule, which allows drivers with a stable insulin regimen and properly controlled insulin-treated diabetes to qualify. The rule also ended the old federal diabetes exemption program.
The requirements are in 49 CFR 391.46:
- Your treating clinician, the provider who manages and prescribes your insulin, completes the Insulin-Treated Diabetes Mellitus Assessment Form, MCSA-5870.
- You see a certified medical examiner within 45 days after the clinician signs the form, and at least once a year.
- You keep blood sugar records on an electronic glucometer that stores the date and time of each reading. Without at least 3 months of records, you can be certified for no more than 3 months.
- You are not qualified if you are not keeping a stable insulin regimen or have severe non-proliferative or proliferative diabetic retinopathy.
- After a severe low blood sugar episode (one needing help from others, or causing loss of consciousness, seizure or coma), you must stop driving until your clinician clears you and completes a new form.
Diabetes that is not treated with insulin does not have a separate federal standard. Examiners apply the general physical standards.
Life insurers look at diabetes in more detail than the DOT rule. They commonly ask about your type of diabetes, age at diagnosis, recent A1C results, medications and any complications. Our guide to life insurance with pre-existing conditions explains how that process generally works.
How do weight and BMI factor in?
There is no BMI limit in the federal physical standards. The standards in 391.41 do not mention weight or BMI. Weight matters to your medical card mainly because the handbook lists obesity and high BMI as risk factors for sleep apnea.
Life insurers, by contrast, commonly compare your height and weight to their own charts when they set your rate. Weight combined with conditions like high blood pressure or diabetes can affect your price more than weight alone. Because each insurer uses its own charts, comparing several insurers can make a difference.
How is the DOT physical different from a life insurance exam?
Both check your health, but they answer different questions:
| DOT physical | Life insurance application |
|---|---|---|
Question it answers | Can you safely drive a commercial vehicle? | What is the insurer's risk of paying a claim? |
Who decides | A certified medical examiner, using FMCSA standards | The insurer's underwriters, using their own guidelines |
Result | Qualified (with a card for up to 24 months) or not qualified | Approved at a price, approved with changes, postponed or declined |
How long it lasts | Until your card expires | For the life of the policy, if premiums are paid |
Because the rules differ, one outcome does not decide the other. A driver who gets only a 1-year card for blood pressure may still qualify for coverage. A driver who passes the physical may still be rated for other reasons.
What if a medical condition takes you off the road?
Losing your medical card can mean losing your income and any life insurance tied to your job at the same time. Our guide on what happens to your life insurance if you stop driving covers what ends and what you may be able to keep.
If you are buying coverage after a new diagnosis, you still have options:
- Fully underwritten policies review your medical records and may offer the best price if your condition is controlled.
- Simplified issue and no-exam policies skip the medical exam but ask health questions. See no-medical-exam life insurance.
- Guaranteed issue policies do not ask health questions but usually pay a limited benefit during the first years.
Some policies also include riders that pay part of the death benefit early after a qualifying serious illness. Learn more in living benefits for truck drivers.
How can you get the best result when you apply?
A little preparation helps:
- Gather your medication list, recent blood pressure readings, sleep study results and CPAP use reports, and recent A1C results if you have diabetes.
- Apply when your condition is stable and treated, not in the middle of a medication change.
- Ask an agent which insurers tend to be more flexible with your specific condition.
- Decide how much coverage your family needs before you shop. Our life insurance calculator can help.

Frequently asked questions
How long is a DOT medical card good for?
Up to 24 months under 49 CFR 391.45. Drivers with insulin-treated diabetes must be recertified at least every 12 months, and medical examiners can issue shorter cards for conditions like high blood pressure.
Check trucker optionsDoes FMCSA have a BMI limit for truck drivers?
No. The physical standards in 49 CFR 391.41 do not include a BMI cutoff. FMCSA's Medical Examiner's Handbook lists obesity and a high BMI as one of several risk factors examiners weigh when deciding whether to recommend a sleep study.
Check trucker optionsCan I get life insurance if I failed my DOT physical?
Possibly. The DOT decision is about safe driving, not life expectancy, and insurers make their own decisions. Depending on your health, you may still qualify for a fully underwritten policy, a simplified issue policy or a guaranteed issue policy with a graded death benefit.
Check trucker optionsWill using a CPAP machine help my life insurance application?
Insurers generally want to know how severe your sleep apnea is and whether you use your treatment consistently. Records showing regular CPAP use can support your application, but each insurer sets its own rules and no result is guaranteed.
Check trucker optionsShould I apply for life insurance before my next DOT physical?
If your health is stable now, applying sooner can make sense, because many term policies keep the same premium for the whole term once issued. If you have a new diagnosis, getting it treated and documented first may give an insurer a clearer picture.
