A DOT physical in Texas is a standardized medical exam that checks whether you can safely operate a commercial motor vehicle. The examiner works through a federal form (MCSA-5875) and evaluates your vision, hearing, blood pressure and pulse, a urine sample, your cardiovascular and musculoskeletal condition, and your full medical history. The same federal standards under 49 CFR Part 391 apply whether you drive across state lines or stay inside Texas, so what a DOT physical consists of in Texas is the same exam a driver takes anywhere else in the country.
What the Examiner Checks
The physical is more thorough than a typical annual checkup. Each section of the form targets a body system that matters for safe driving, and the examiner records findings against specific federal thresholds.
Vision
You need distant visual acuity of at least 20/40 in each eye separately and in both eyes together, with or without corrective lenses. Your horizontal field of vision must be at least 70 degrees in each eye, and you must be able to recognize standard red, green, and amber traffic signal colors.1eCFR. 49 CFR 391.41 – Physical Qualifications for Drivers If you wear glasses or contacts, bring them. You’ll be tested with them on.
A 2022 rule change created an alternative vision evaluation for drivers who don’t meet the standard in their worse eye, replacing the older individual exemption route.2Federal Motor Carrier Safety Administration. Qualifications of Drivers – Vision Standard If your better eye meets 20/40 with 70 degrees of field, your condition is stable, and you’ve had time to adapt, the examiner can still certify you.
Hearing
You must be able to hear a forced whisper from at least five feet away, tested in your better ear. Hearing aids are allowed during the test. If you don’t pass the whisper check, the examiner moves to an audiometric test. You pass if your average hearing loss in the better ear is no greater than 40 decibels at 500, 1,000, and 2,000 Hz.3Federal Motor Carrier Safety Administration. What Are the Hearing Requirements for CMV Drivers
Blood Pressure and Pulse
Blood pressure is one of the most common reasons drivers get a shortened certification or fail outright. The FMCSA sets staged thresholds that run at the time of your exam:4Federal Motor Carrier Safety Administration. What Is the Effect on Driver Certification Based on FMCSA Hypertension Stages
- Below 140/90: full two-year certification.
- Stage 1 (140–159 / 90–99): one-year certification.
- Stage 2 (160–179 / 100–109): one-time three-month temporary certification. Getting below 140/90 within those three months earns a one-year card.
- Stage 3 (180/110 or higher): disqualified until you get below 140/90, then six-month intervals.
If your pressure tends to run high, managing it in the days before the appointment can be the difference between a two-year card and a short one. The examiner also checks resting pulse for irregularities that might signal a cardiovascular problem.
Urinalysis
The examiner collects a urine sample and tests it for protein, blood, and sugar. These markers help flag conditions like diabetes or kidney disease.5Federal Motor Carrier Safety Administration. Medical Examination Report Form MCSA-5875 Abnormal results don’t automatically disqualify you; they trigger follow-up testing to identify the cause.
This urinalysis is not a drug test. The DOT drug and alcohol testing program is a separate process governed by 49 CFR Part 40 and run through your employer. The two often get confused because both involve urine, but they serve different purposes.
Physical and Musculoskeletal Examination
The examiner evaluates your body’s ability to handle the physical demands of driving a CMV. That means checking neck range of motion, your spine for deformities or tenderness, and your extremities for strength, mobility, and function. You may be asked to demonstrate grip strength, walk so the examiner can observe your gait, and show that you can climb in and out of a cab.
Federal standards require no loss of a foot, leg, hand, or arm unless you hold a Skill Performance Evaluation certificate. Even with all limbs intact, any impairment that interferes with gripping a steering wheel, operating pedals, or performing other normal driving tasks can be disqualifying.1eCFR. 49 CFR 391.41 – Physical Qualifications for Drivers Arthritis, neuromuscular disorders, and spinal problems are evaluated on severity, with the question always being whether the condition interferes with safe vehicle operation.
Medical History Review
Before the hands-on exam, you fill out a detailed health history covering past surgeries, hospitalizations, current medications, and chronic conditions. The examiner reviews it and asks follow-ups. Be thorough and honest here. Omitting a condition or medication doesn’t make it disappear, and if the omission surfaces later, it can create problems for your certification and your CDL.
Conditions That Change How the Exam Goes
Several common conditions don’t automatically disqualify you, but they do add steps.
Diabetes
Diabetes managed with diet, exercise, or non-insulin medications can usually be certified without extra steps. Insulin-treated diabetes once required a separate FMCSA exemption, but that program was eliminated. Certified medical examiners now evaluate and certify insulin-treated drivers directly, in consultation with the driver’s treating clinician.6Federal Motor Carrier Safety Administration. FMCSA Eliminates the Federal Diabetes Exemption Program Bring your most recent Hemoglobin A1C results and any documentation from your endocrinologist or primary care provider.
Sleep Apnea
No single BMI or neck measurement triggers automatic disqualification, but examiners screen actively for obstructive sleep apnea. Risk factors that may prompt a referral for a sleep study include a BMI of 28 or higher, a neck circumference of 17 inches or more for men (15.5 for women), chronic loud snoring, witnessed breathing pauses during sleep, and daytime sleepiness.7Federal Motor Carrier Safety Administration. Expert Panel Recommendations – Obstructive Sleep Apnea and Commercial Motor Vehicle Driver Safety
If you’ve been diagnosed and use a CPAP machine, bring your compliance data. The accepted standard is at least four hours of use on 70 percent or more of nights. Drivers newly on CPAP often receive stepped conditional certifications, typically one month, then three months, then one year, as they build a compliance record.
Heart Conditions and Seizure Disorders
Any cardiovascular condition associated with fainting, sudden collapse, or heart failure is disqualifying under the federal standard. That covers unstable angina, recent heart attack, and uncontrolled arrhythmias, among others.1eCFR. 49 CFR 391.41 – Physical Qualifications for Drivers Many heart conditions are manageable, and drivers with stable, treated cardiovascular disease are commonly certified on one-year intervals.
Epilepsy and other conditions likely to cause loss of consciousness are also disqualifying. The FMCSA runs exemption programs for drivers with seizure disorders and hearing impairments who can show a safe driving history, but these apply only to interstate commerce.8Federal Motor Carrier Safety Administration. Driver Exemption Programs Intrastate exemptions are handled by the state.
What to Bring
Walking in prepared saves time and prevents follow-up appointments. Bring:
- A valid Texas driver’s license or other government-issued photo ID.
- A full medication list with names, dosages, and prescribing doctors, including over-the-counter products.
- Corrective lenses or hearing aids you normally use while driving.
- Specialist documentation: recent A1C results if you have diabetes, sleep study results or CPAP compliance reports if you have sleep apnea, or clearance letters from a cardiologist or neurologist for relevant conditions.
- Surgical or hospital discharge records if you’ve had a recent procedure.
The more documentation you hand over up front, the less likely the examiner is to defer certification pending additional records.
How Long Your Certificate Lasts
A standard medical examiner’s certificate is valid for up to two years. Drivers with certain conditions get shorter certifications that require more frequent monitoring:9Federal Motor Carrier Safety Administration. How Long Is My Medical Certificate Valid
- One year for treated Stage 1 high blood pressure, stable heart disease, insulin-treated diabetes, and other conditions the examiner wants to review annually.
- Three to six months for Stage 2 hypertension (temporary, to allow time to lower blood pressure) or newly treated sleep apnea while CPAP compliance is being established.
Your certification clock starts on the date of the exam, not when the result reaches your state record. Waiting weeks to act on your results costs you time off the back end of the card.
Who Needs the Exam in Texas
Federal regulations under 49 CFR Part 391 require a DOT physical for anyone driving a commercial motor vehicle in interstate commerce, meaning any vehicle weighing 10,001 pounds or more, any vehicle carrying placarded hazardous materials, or any vehicle designed to transport more than 15 people including the driver.10eCFR. 49 CFR Part 391 – Qualifications of Drivers and Longer Combination Vehicle (LCV) Driver Instructors Crossing a state line, or hauling cargo that’s part of an interstate shipment even if you stay inside Texas, puts you under those standards.
Texas also requires a current medical examiner’s certificate for most intrastate CDL holders. When you apply for or renew a Texas CDL, DPS asks you to self-certify into one of four categories. Non-excepted interstate (Category 1) and non-excepted intrastate (Category 3) both require a DOT physical and current medical certificate.11Texas Department of Public Safety. New Medical Certification Requirements – A Guide for Commercial Drivers The two excepted categories cover certain government, school bus, agricultural, and emergency operations and don’t require a federal medical certificate.
Finding a Certified Examiner and What It Costs
Your exam has to be performed by a medical examiner listed on the FMCSA’s National Registry of Certified Medical Examiners. An exam performed by anyone not on the registry will not produce a valid certificate. You can search for examiners near you using the FMCSA’s online tool by entering your location and a search radius.12Federal Motor Carrier Safety Administration. Search Medical Examiners – FMCSA National Registry The registry includes physicians, physician assistants, nurse practitioners, chiropractors, and other qualified providers who’ve completed FMCSA training and testing.
A standard DOT physical in Texas typically runs between $85 and $225, depending on the clinic and location. Your employer may cover the cost or direct you to a specific provider. If you’re paying out of pocket, call ahead. Prices vary a lot, even within the same city.
