Quick answer
Almost nothing on the DOT exam is about perfect health — it's about whether your conditions are safely controlled. Blood pressure at or below 140/90 earns a 2-year medical card; higher readings earn shorter cards while you bring it down, and only 180/110 or above pauses certification until it's controlled. Diabetes — with or without insulin — has a clear federal path, and treated sleep apnea certifies routinely with CPAP compliance data. The exam's urine test is a health screen, not a drug test. At Evolve Health in Denton, DOT physicals are $99 flat with your medical card issued the same visit — and if a number needs work, the same clinic that manages your blood pressure or diabetes can re-examine you when you're ready.
The DOT physical follows the FMCSA physical qualification standards in federal regulation (49 CFR 391.41). A Certified Medical Examiner checks your history, vision, hearing, blood pressure, and a urine screen, then decides how long your medical certificate runs — up to two years. Here's what drivers get wrong most often: a condition on your record is rarely the end of the story. Examiners certify drivers with managed blood pressure, diabetes, heart history, and sleep apnea every day. What matters is control, documentation, and follow-through — and a shorter card is simply the system scheduling a recheck, not a career verdict.
Blood pressure: the FMCSA ladder, exactly
Blood pressure is the most common reason a driver leaves with a shorter card — and the most fixable finding on the whole exam. FMCSA uses a simple ladder. Your reading at the exam decides your card:
| Your reading | What it means | Your card |
|---|---|---|
| 140/90 or below | Meets the standard | 2-year medical card |
| 141–159 / 91–99 | Stage 1 hypertension | 1-year medical card |
| 160–179 / 100–109 | Stage 2 hypertension | One-time 3-month card; once treated to 140/90 or below, a 1-year card from the exam date |
| 180/110 or above | Above the standard | Certification paused until your blood pressure is controlled — then you re-test |
A few things drivers are glad to hear: being on blood pressure medication is common and does not disqualify you — drivers on medication are certified every day, typically on the 1-year monitoring cycle. Your examiner can also re-measure after you've had a few minutes to rest, because a rushed, caffeine-loaded morning reads higher than your real number. Help that number tell the truth: go easy on coffee, energy drinks, and salty food the morning of your exam, and bring your medication list. Read the ladder for what it is — a high reading is a timeline, not a verdict.
Vision and hearing standards
These two are pass-mark standards, and corrective help is fully allowed:
- Vision: at least 20/40 acuity in each eye, with or without glasses or contacts, plus at least a 70-degree field of vision (peripheral vision) in the horizontal meridian of each eye, and the ability to tell red, green, and amber traffic-signal colors apart. Wear glasses or contacts? Bring them — corrected vision counts.
- Hearing: you should be able to perceive a forced whisper at 5 feet or more in your better ear, with or without hearing aids — or meet the equivalent audiometric (hearing test machine) standard. Hearing aids are welcome; bring them charged.
If you fall short on vision, an eye exam and an updated prescription are usually the whole fix, and federal exemption pathways exist for some vision situations — your examiner can walk you through what applies to you.
Diabetes, A1C, and the insulin process (MCSA-5870)
Diabetes does not disqualify you from driving — and that includes diabetes treated with insulin. Two facts clear up most of the confusion:
- There is no federal A1C cutoff. FMCSA does not set a single A1C number that passes or fails you. Your A1C is part of the picture your examiner weighs — along with your regimen's stability, any history of severe low-blood-sugar episodes, and complications — because certification is an individualized assessment. A very high reading usually means "get control first, then certify," which is a plan, not a ban.
- Insulin has a defined process, not an automatic no. Since FMCSA's 2018 diabetes rule, drivers with insulin-treated diabetes no longer need a federal exemption. Your treating clinician — the clinician who manages your insulin — completes the Insulin-Treated Diabetes Mellitus Assessment Form, MCSA-5870, confirming a stable regimen and properly controlled diabetes. The form must be completed within 45 days before your exam, your examiner reviews it alongside your physical, and certification runs up to 12 months at a time.
Drivers whose diabetes is managed with diet or non-insulin medication follow a simpler version of the same idea: show that it's controlled and monitored, and certification is routine — often on a 1-year cycle so your progress is rechecked. Either way, bring your recent A1C result and your medication list, and expect an honest conversation about low-blood-sugar episodes, because that's the safety question your examiner is really asking.
Sleep apnea: screened, not an automatic fail
Sleep apnea is the finding drivers fear most, so let's be precise: there is no rule that sleep apnea disqualifies you. What examiners do is screen for risk — your history, symptoms like loud snoring and daytime sleepiness, and physical measures — and, if the risk looks real, ask for a sleep study to settle the question. If a study confirms moderate-to-severe apnea, the path forward is treatment, and it is a well-worn path:
- CPAP therapy is the standard treatment, and drivers who use it are certified routinely.
- Compliance data is how you prove it: usage of at least 4 hours a night on at least 70% of nights is the benchmark examiners look for. Your machine records it automatically — bring the compliance printout from your equipment provider.
- Certification typically runs 1 year at a time, with your compliance reviewed at each renewal.
The situation examiners are actually guarding against is untreated apnea with real daytime sleepiness behind the wheel. Treated, documented apnea is routine paperwork — drivers across Denton County renew on it every year.
Other conditions your examiner will ask about
A few more areas come up in the health history. The pattern is the same — documentation turns question marks into certifications:
- Heart conditions (heart attack, stents, heart failure, rhythm problems): many drivers are certified with cardiology records, recent test results, and a note that the condition is stable. Bring whatever your cardiologist has given you.
- Seizure history: federal standards are stricter here, and certification depends on the specifics — seizure-free periods, medication, and in some cases an FMCSA exemption. This is one to discuss openly with your examiner rather than leave off the form.
- Medications: your examiner reviews your list for anything that causes drowsiness or impairs alertness. Most common prescriptions are fine; a complete, honest list is what makes the review quick.
- Recent surgery or hospitalization: healing time plus clearance to return to duty is usually the whole story — bring discharge paperwork if it's fresh.
The drug-test question, settled
This rumor keeps more drivers from booking than any actual standard: the DOT physical does not include a drug test. The exam does include a urinalysis — but it screens health markers: specific gravity, protein, blood, and sugar in the urine, which flag things like kidney issues or undiagnosed diabetes. Drug and alcohol testing is a completely separate program your employer runs under federal rules (49 CFR Part 40) — pre-employment, random, and post-accident testing with its own chain-of-custody paperwork. Your employer may schedule both around the same time, but they are two different processes, and the physical itself is a health exam, full stop. No fasting is required for it, either.
Didn't pass — or got a short card? Here's your path back
First, breathe: not passing on the first try doesn't end your driving career. The usual outcomes are a shorter medical card — 3, 6, or 12 months — while a condition like blood pressure or blood sugar is brought under control, or a pause in certification with a clear target to hit. Then you treat the condition and re-test. Most of the conditions that shorten cards respond in weeks to a few months of real management.
This is exactly where Evolve Health is built differently from a DOT-only exam shop. We're a primary care clinic that also certifies: the same team that performs your DOT exam can manage your blood pressure, adjust your diabetes plan, and follow your sleep apnea treatment — then re-examine you in the same building, with your records already here. No faxing charts between strangers, no starting over. And a practical tip: book before your current card expires — driving on an expired medical card risks a CDL downgrade, and the expired-card scramble is the one deadline in this process that's entirely avoidable.
What to bring to your DOT exam
- Your driver's license (and CDL if you already hold one)
- Glasses or contacts if you wear them, and hearing aids if you use them
- A complete list of your medications, with doses
- Your CPAP compliance printout, if you use a CPAP — and sleep study results if you have them
- Cardiology or specialist records for any heart condition
- Your completed MCSA-5870 form from your treating clinician, if you use insulin (completed within the last 45 days)
- Your most recent A1C result, if you have diabetes
- Discharge or clearance paperwork for any recent surgery or hospitalization

Frequently asked questions
Can you pass a DOT physical with high blood pressure?
Yes — most drivers with high blood pressure are certified. The FMCSA ladder: 140/90 or below earns a 2-year card; Stage 1 (141–159/91–99) earns a 1-year card; Stage 2 (160–179/100–109) earns a one-time 3-month card while you bring it down, then a 1-year card once you're at 140/90 or below; 180/110 or above pauses certification until your blood pressure is controlled. Evolve Health in Denton can manage your blood pressure and do your exam in the same clinic.
Does sleep apnea disqualify you from a DOT physical?
No. Sleep apnea is screened for, not an automatic disqualifier. If a sleep study shows moderate-to-severe apnea, the path to certification is treatment — typically CPAP — with compliance data showing use of at least 4 hours a night on at least 70% of nights. Drivers with treated, compliant sleep apnea are certified every day, usually on a 1-year card with an annual compliance review.
Does a DOT physical include a drug test?
No. A DOT physical includes a urinalysis that screens kidney function and blood sugar — it is not a drug test. Drug and alcohol testing is a separate process your employer runs under federal rules (49 CFR Part 40), with its own chain of custody. At Evolve Health in Denton, the $99 DOT exam covers the full physical and urinalysis, with your medical card issued the same visit.
What happens if you don't pass a DOT physical?
Not passing doesn't end your driving career. Most drivers get a shorter medical card — 3, 6, or 12 months — while a condition like blood pressure or blood sugar is brought under control, then re-test. Evolve Health in Denton can manage the condition and repeat your DOT exam when you're ready, all in one clinic.
How much is a DOT physical in Texas?
A DOT physical in Denton costs $99 at Evolve Health — one flat fee, no add-ons. Texas clinics typically charge $75–$150, and the exam must be performed by an FMCSA-certified medical examiner. Your medical card is issued the same visit. Walk in Mon–Fri, 7 AM–5 PM, or call (940) 257-2002.
How long is a DOT medical card valid?
A DOT medical card is valid for up to 24 months. If you have a condition that needs monitoring — like high blood pressure or diabetes — your examiner may issue a 3-, 6-, or 12-month card instead so your progress is rechecked on schedule. Evolve Health in Denton handles renewals and re-exams — walk in before yours expires.
