What Every Commercial Driver Needs to Know Before Their DOT Physical
If you're a commercial driver heading into a DOT physical in 2026, you've probably got questions. What exactly are they checking? What numbers do you need to hit? What happens if something comes back outside the range? These are fair questions — and you deserve straight answers before you walk through the door.
The DOT physical requirements haven't changed dramatically this year, but there's a lot of outdated, confusing information floating around online. As an FMCSA-certified medical examiner with more than 40 years of experience examining commercial drivers, Dr. David Jacobsen has put together this plain-English breakdown of exactly what the FMCSA medical requirements cover — system by system — so you can show up prepared and confident.
Whether you're a first-time CDL driver or coming in for a renewal, this is your definitive reference.
Why the DOT Physical Exists
The Federal Motor Carrier Safety Administration (FMCSA) requires that every commercial driver operating a vehicle in interstate commerce hold a valid DOT medical certification. This isn't just a formality. The physical exists to make sure drivers can safely operate a commercial motor vehicle — protecting you, your fellow drivers, and everyone sharing the road.
To receive your medical card, you must pass a complete physical examination conducted by a licensed medical examiner registered with the FMCSA National Registry. At OneCare CDL, Dr. Jacobsen is fully certified to conduct your exam and issue your card on the same day.
DOT Physical Requirements 2026: System-by-System Breakdown
Here's what the FMCSA examiner will evaluate during your DOT physical, and what you need to know going in.
Vision Requirements
You must have at least 20/40 vision in each eye — with or without corrective lenses. You also need a horizontal field of vision of at least 70 degrees in each eye, the ability to distinguish colors on traffic signals (red, green, amber), and adequate distant binocular acuity.
If you wear glasses or contacts, bring them. If one eye does not meet the standard but the other does, the alternative vision standard at 49 CFR 391.44 may apply — something Dr. Jacobsen can walk you through if it fits your situation.
Hearing Requirements
You must be able to perceive a forced whispered voice in the better ear at a distance of at least 5 feet — with or without a hearing aid. Alternatively, this can be tested using an audiometric device, where you must not have average hearing loss in the better ear greater than 40 dB.
Hearing aids are permitted. If you rely on one, wear it to your exam.
DOT Physical Blood Pressure Requirements
This is one of the most common areas where drivers have questions — and concerns. Here's how it breaks down:
- Stage 1 (140-159 and/or 90-99): the criteria provide for certification for one year. Examinations are recommended annually thereafter, with a target at or below 140/90.
- Stage 2 (160-179 and/or 100-109): the criteria provide for a one-time certification of three months. Where treatment is well tolerated and the reading is 140/90 or less at the follow-up examination, the criteria provide for certification for one year.
- Stage 3 (at or greater than 180 systolic and 110 diastolic): the criteria provide that an individual should not be qualified, even for a short period, until the reading is reduced to 140/90 or less and treatment is well tolerated, and then provide for certification for six months at a time
DOT physical blood pressure requirements are strictly enforced, but they're also manageable. If you're on medication, take it as prescribed before your exam. If you're concerned about your numbers, talk to your primary care provider before your exam date.
Cardiovascular Requirements
The examiner will evaluate your cardiovascular history and current status. Conditions like coronary artery disease, arrhythmias, and a history of cardiac events are reviewed on a case-by-case basis. Many drivers with treated heart conditions can still qualify — often with additional documentation from their cardiologist.
You'll be asked to disclose any cardiovascular history on your medical history form. Be honest and thorough. Withholding information can put your certification — and your career — at risk.
Neurological Requirements
Your neurological health is a major focus of FMCSA medical requirements. The examiner will look for any history of:
- Epilepsy or seizure disorders
- Loss of consciousness or unexplained syncope
- Head trauma with lasting effects
- Neurological conditions that could impair driving
With a history of epilepsy or a seizure disorder, the Medical Advisory Criteria allow an examiner to certify a driver who has been seizure free and off antiseizure medication for 10 years or more; a current diagnosis, or taking antiseizure medication to prevent seizures, is not qualifying, and FMCSA runs a federal seizure exemption program. A single unprovoked seizure is assessed under separate criteria with a shorter seizure-free period. Records from your treating neurologist help the examiner.
Metabolic and Diabetes Requirements
Insulin-treated diabetes is assessed under the qualification standard at 49 CFR 391.46: before each examination the treating clinician completes the Insulin-Treated Diabetes Mellitus Assessment Form (MCSA-5870), and the medical examiner then decides, using independent medical judgment, whether the standard is met. A medical card issued under the standard is valid for no more than 12 months and can be shorter. Bring the MCSA-5870, completed, signed and dated by your treating clinician no more than 45 days before the exam.
Drivers managing diabetes with oral medication rather than insulin are not subject to the 49 CFR 391.46 standard, provided blood glucose is controlled. HbA1c levels and recent lab work may be reviewed.
Musculoskeletal Requirements
You need to demonstrate that you have adequate strength, range of motion, and reflexes to safely operate a CMV. This includes the ability to grip, reach controls, and respond physically in emergency situations. Limb loss or impairment doesn't automatically disqualify a driver — FMCSA has a Skill Performance Evaluation (SPE) certificate program for drivers with limb differences.
Respiratory Requirements
The examiner will assess your respiratory health through history and physical exam. Conditions like sleep apnea are increasingly scrutinized under FMCSA medical requirements. If you've been diagnosed with obstructive sleep apnea, bring your treatment records, such as a CPAP compliance report: the examiner evaluates whether the condition is adequately treated.
If you haven't been evaluated for sleep apnea but your exam raises red flags — high BMI, neck circumference, reported fatigue — the examiner may recommend a sleep study before issuing your card.
Urinalysis
A urine sample is required at every DOT physical. The examiner checks for glucose, protein, and blood in the urine — not substances. This is a medical screening test, not a drug test. It helps identify potential indicators of diabetes, kidney disease, or other conditions.
If you need a DOT drug test alongside your physical, OneCare CDL offers a convenient CDL Physical + Drug Test combo so you can handle both in one visit.
Common Questions Drivers Ask Before Their DOT Physical
Can I still pass if I take prescription medications?
Taking a prescription medication does not by itself rule out certification. The key is disclosure. List every medication you're taking on your medical history form. The examiner weighs each medication individually, and some — including certain sleep aids, anxiety medications, and narcotics — call for additional review, such as a note from the prescriber.
How long does a DOT physical take?
Typically 20–30 minutes. At OneCare CDL, we're efficient without cutting corners. New drivers can expect a thorough but straightforward exam with same-day medical card issuance if you pass.
How long is a DOT medical card valid?
Up to 24 months — but many drivers receive shorter-term cards if they have conditions being monitored, such as high blood pressure or diabetes. Some conditions require annual or even more frequent recertification.
What should I bring to my DOT physical?
- Your driver's license or valid government-issued ID
- A list of your current medications (including dosages)
- Glasses or contacts if you use them
- Hearing aids if you use them
- Any relevant medical records for disclosed conditions
- Your previous medical card if you're renewing
