What is a DOT Physical?

A DOT physical is a federally required medical exam designed to ensure that commercial vehicle drivers are physically, mentally, and emotionally fit to safely operate large vehicles. The purpose is simple: to protect the safety of the driver and the public by reducing the risk of accidents caused by medical conditions behind the wheel.

Required by the Department of Transportation (DOT) and regulated through the Federal Motor Carrier Safety Administration (FMCSA), the exam evaluates a driver’s overall health, including vision, hearing, blood pressure, and vital organ function. It also checks for signs of medical conditions that could interfere with safe driving, such as sleep apnea, epilepsy, uncontrolled diabetes, or substance abuse.

At Medallus Urgent Care, we understand how important this exam is for your career. Our certified medical examiners provide quick, convenient, and affordable DOT physicals, helping you meet federal requirements without unnecessary delays. Whether you’re a new driver getting certified or a current CDL holder renewing your medical card, Medallus Urgent Care is here to support your professional journey with expert care and same-day service.

Not all medical conditions will automatically disqualify you from passing a DOT physical, but certain health issues can raise concerns about your ability to safely operate a commercial vehicle. The FMCSA has specific medical standards to help ensure road safety. Below are some of the more common disqualifying conditions:

● Uncontrolled high blood pressure

● Poor vision or hearing (even with corrective aids, if below required standards)

● Insulin-dependent diabetes (in some cases without proper documentation)

● History of epilepsy or seizures

● Substance abuse or a failed drug/alcohol test

● Heart conditions not cleared by a specialist

● Sleep apnea that is untreated or uncontrolled

● Certain mental health disorders that impair judgment or focus

It’s important to know that many of these conditions are not automatic disqualifiers. If you have a health condition, bringing supporting documents from your doctor can help your case. At Medallus Urgent Care, our experienced examiners work with you to understand your medical history and help you stay compliant with DOT standards. We also provide referrals and guidance if additional testing or clearance is needed.

A DOT physical and a regular physical exam may seem similar, but they serve very different purposes. A standard physical exam checks your overall health and wellness—usually done once a year to manage chronic conditions, update vaccines, and discuss lifestyle. It’s more preventive and personal, tailored to your individual health goals.

A DOT physical, however, is a federally regulated medical screening with a clear focus: determining whether you meet the medical requirements to safely operate a commercial motor vehicle (CMV). It follows a strict checklist from the Federal Motor Carrier Safety Administration (FMCSA) and includes:

● Vision and hearing testing

● Blood pressure and pulse rate check

● Urinalysis (for protein, sugar, blood)

● A comprehensive medical history review

● Evaluation of the heart, lungs, spine, and neurological function

● Drug and alcohol screening (if required)

At Medallus Urgent Care, we perform both types of physicals but ensure that your DOT exam is completed according to FMCSA standards. We also explain the difference clearly so you get the exam you need—no surprises, no confusion, and no delays in getting your DOT medical card.

A DOT physical is typically required every two years, or every 24 months, for commercial drivers who meet all health requirements. However, some drivers may need to take the physical more frequently, depending on their medical history and current health conditions.

If you have a condition like high blood pressure, diabetes, or are recovering from a recent surgery or heart issue, Dr. Rachot Vachathrone, MD, may issue a shorter-term medical certificate—often 3 months, 6 months, or 1 year. This allows time to manage the condition and return for a re-evaluation. It’s not uncommon for drivers with controlled conditions to be certified for one year at a time.

Drivers must carry a valid Medical Examiner’s Certificate (MEC) at all times while operating a commercial vehicle. Letting your certificate expire can mean losing your CDL privileges temporarily.

At Medallus Urgent Care, we make it easy to stay on top of your DOT certification. Our staff offers reminders, walk-in appointments, and same-day results so you never miss a deadline. Whether you need a two-year renewal or a follow-up exam, Medallus Urgent Care ensures you stay compliant and back on the road quickly and safely.
