DOT Physical Exam 2026: Requirements, Cost, Medical Card & Disqualifying Conditions

If you hold a commercial driver’s license or you’re working toward one, the DOT physical exam is something you simply can’t skip. It’s a federal requirement under 49 CFR Part 391 — and it must be completed before you can legally operate a commercial motor vehicle (CMV) on public roads. A lot of drivers find the process confusing the first time around, especially when it comes to what’s actually tested, what can get you disqualified, and how long the certificate lasts. In 2026, the core requirements haven’t changed dramatically, but there are a few updates worth knowing.

What Is the DOT Physical Exam and Who Needs It?

The DOT physical — officially called the DOT Medical Examination — is a standardized health evaluation required by the Federal Motor Carrier Safety Administration (FMCSA) for any driver operating a commercial motor vehicle in interstate commerce. You need one if you operate a vehicle with a GVWR of 10,001 pounds or more, transport 9 or more passengers for compensation, transport 16 or more passengers regardless of compensation, or haul hazardous materials requiring placarding.

If you’re pursuing a CDL for the first time, you’ll need to pass the DOT physical before your state issues a Commercial Learner’s Permit (CLP). See our step-by-step CDL licensing guide for how this fits into the full process.

Intrastate vs. Interstate Drivers

If you drive only within one state, your state may have its own medical standards that differ slightly from federal FMCSA requirements. Some states adopt the federal standard entirely; others have modified rules. But if you ever cross a state line, federal rules apply immediately — so most drivers simply meet the federal standard regardless of their route type.

Who Can Perform the DOT Physical?

Not every doctor or urgent care clinic qualifies. You must go to a licensed medical examiner listed on the FMCSA National Registry of Certified Medical Examiners. Medical examiners on the registry include physicians (MDs and DOs), nurse practitioners, physician assistants, chiropractors, and optometrists — but only if they’ve completed FMCSA’s required training and passed the certification exam. If your regular doctor isn’t on the registry, their certificate is not valid.

What Does the DOT Physical Include?

Medical History Review

You’ll complete a health history form before the exam. This covers current medications, surgeries, hospitalizations, and chronic conditions. Submitting inaccurate information on this form is a federal violation under 49 CFR 390.35 and can result in disqualification.

Vision Test

You must have at least 20/40 acuity in each eye, with or without corrective lenses, and a field of vision of at least 70 degrees in the horizontal meridian for each eye. Color recognition (red, green, amber) is also tested. Bring your glasses or contacts.

Hearing Test

You must perceive a forced whispered voice at 5 feet or more in your better ear, with or without a hearing aid.

Blood Pressure and Pulse

Blood pressure is one of the most common reasons drivers receive a shortened certificate period. Here’s how readings affect certification:

Urinalysis

The urinalysis at a DOT physical is NOT a drug test. It screens for glucose (diabetes indicator) and protein (kidney function). Drug testing is a completely separate program — covered in our DOT drug test and Clearinghouse guide.

Physical Examination

The examiner conducts a head-to-toe physical covering eyes, ears, cardiovascular system, lungs, abdomen, spine, extremities, neurological function, and skin. They’re looking for any condition that could impair your ability to safely operate a commercial vehicle.

DOT Physical Disqualifying Conditions

Sleep Apnea — A Growing Concern in 2026

Obstructive sleep apnea (OSA) is one of the most frequently flagged conditions in DOT physicals. Research published in the Journal of Clinical Sleep Medicine found that an estimated 28% of commercial truck drivers have sleep apnea — nearly three times the general population rate. If your examiner suspects OSA based on your neck circumference, BMI, or reported symptoms, they may require a sleep study before certifying you. CPAP-compliant drivers can typically get certified — but you need to show your usage data at every physical.

How Long Does the Medical Certificate Last?

• 24 months — Standard for drivers meeting all requirements with no monitored conditions
• 12 months — Controlled Stage 1 hypertension or diet-managed diabetes
• 6 months — Some cardiovascular conditions under monitoring
• 3 months — Temporary certificate while awaiting specialist review

Once your certificate expires, you can’t legally operate a CMV until you pass a new exam. Your carrier is required to keep a current copy in your Driver Qualification File, and an expired medical card is one of the first things a DOT inspector checks during a roadside inspection.

Submitting Your Certificate to Your State DMV

CDL holders are required to submit their medical examiner’s certificate to their state driver licensing agency. In many states this now happens electronically through integration between the national registry and state systems — but always verify your MVR reflects a current, valid medical certification status. If it doesn’t appear, contact your state DMV to submit a physical copy.

DOT Physical Cost in 2026

Insurance typically doesn’t cover DOT physicals — they’re occupational requirements rather than medical care. Owner-operators can deduct the cost as a business expense. See our owner-operator guide for other deductible business expenses.

How to Prepare for Your DOT Physical

The Night Before

• Get a full night of sleep — blood pressure readings are higher when you’re fatigued
• Avoid alcohol for at least 24 hours
• Skip salty, heavy meals right before the exam

Morning of the Exam

• Skip coffee and energy drinks for at least an hour — caffeine temporarily spikes blood pressure
• Avoid tobacco for 30 minutes before the exam
• If you’re on blood pressure medication, take it as prescribed — don’t skip it

What to Bring

• Current driver’s license or CDL
• Glasses or contact lenses if you use them
• Hearing aids if applicable
• Complete medication list with dosages and prescribing doctor’s contact information
• Specialist documentation if you have a managed condition (CPAP usage data, diabetes logs, cardiac clearance letters)
• Previous DOT medical certificate if you have one

FMCSA Exemption Programs

Not meeting the standard doesn’t necessarily mean you can never drive commercially. FMCSA maintains formal exemption programs for conditions that would otherwise disqualify a driver:

• Diabetes Exemption — For insulin-treated drivers with stable control and a treating endocrinologist’s report. More at FMCSA’s diabetes exemption page
• Vision Exemption — For drivers who don’t meet 20/40 in one or both eyes but have demonstrated safe driving
• Seizure Exemption — For drivers seizure-free and off medication for a specified period
• Skill Performance Evaluation (SPE) Certificate — For drivers with limb impairments

Exemption applications take weeks to months to process. Understanding how your health record affects your compliance standing is also closely tied to your overall DOT compliance obligations.

What Happens After Your DOT Physical?

If you pass, the examiner issues a Medical Examiner’s Certificate on Form MCSA-5876. You get a wallet card to carry, and the examiner reports results electronically to the FMCSA registry within 24 hours. Give your carrier a copy immediately for your Driver Qualification File.

If you don’t pass, the examiner explains why and may issue a temporary certificate while you pursue treatment. You’re not permanently barred unless the condition is genuinely unresolvable — so explore your options before giving up.

Set a reminder 90 days before your certificate expires. That gives you time to schedule, address any follow-up the examiner might require, and still have buffer room. Your HOS compliance and everything else on the road depends on having a valid medical card — let it lapse and you’re immediately out of service.
