What to Expect at a DOT Physical Exam

The Department of Transportation (DOT) physical exam is designed to verify your safety as a commercial driver. Knowing what to expect can significantly lower your anxiety and help you prepare to pass the exam smoothly. At The Accident Doctor, every exam is performed by an FMCSA National Registry Certified Medical Examiner, and most drivers are in and out in under 30 minutes.

Before You Arrive: Bring your valid driver license, a complete written list of your current medications with dosages and prescribing doctors, and your glasses, contact lenses, or hearing aids if you use them to drive. If you manage a condition such as diabetes, heart disease, or sleep apnea, bring the supporting documentation — a treating physician clearance letter, recent lab work, or CPAP compliance logs — so the examiner can certify you in a single visit instead of deferring for paperwork.

1. Vision and Hearing Analysis: You must have at least 20/40 vision in each eye (with or without corrective lenses) and a field of vision of at least 70 degrees in the horizontal meridian of each eye. For hearing, you must be able to perceive a forced whisper at a distance of 5 feet in at least one ear, with or without a hearing aid.

2. Blood Pressure and Pulse: Your blood pressure and pulse are checked for signs of hypertension or an irregular heart rhythm. To certify without restriction, your reading should be under 140/90. A reading between 140/90 and 159/99 may result in a one-year card, and higher readings can shorten your certification period or require a documented treatment plan. If your first reading is borderline, we will let you rest and recheck it at no extra charge before finalizing the result.

3. Urinalysis Testing: A quick point-of-care urine sample is checked for protein, blood, and sugar. This is not a drug screen — it screens for underlying conditions such as kidney problems or undiagnosed diabetes. If your employer also requires a DOT drug test, that is a separate collection we can perform during the same visit.

4. Physical Examination: The examiner reviews your ears, eyes, mouth and throat, heart, lungs and chest, abdomen, spine, and neurological reflexes. The goal is to confirm you can safely handle the physical demands of operating a commercial motor vehicle, from extended hours behind the wheel to securing loads and climbing in and out of the cab.

5. Health History Review: You will complete Section 1 of the MCSA-5875 medical history form, which we provide at the office. Answer honestly — the examiner uses your history to decide whether any condition needs supporting documentation. Withholding information can invalidate your certificate later, so it is always better to disclose and bring the paperwork that clears you.

How Long Does the Exam Take? Most DOT physicals at The Accident Doctor take under 30 minutes from check-in to receiving your medical card. There is no fasting required, and while walk-ins are welcome, you can call ahead or check availability at either the Phoenix or Tolleson location to confirm hours before you drive over.

After You Pass: When you meet the standards, the examiner issues your Medical Examiner Certificate (Form MCSA-5876) on the spot and reports the result to the FMCSA National Registry the same day. Keep a copy for your records and submit it to the Arizona MVD before your current card expires to keep your CDL in good standing.

A little preparation goes a long way. Arrive rested and hydrated, skip the caffeine, bring your documentation, and the exam is usually quick and stress-free. If you have questions about your specific health situation before you come in, call our Phoenix or Tolleson office and our team will walk you through exactly what to bring.
