A DOT physical is a medical exam required for any commercial driver. This exam is designed to ensure you are fit to operate a commercial vehicle. To get your commercial driver’s license (CDL), you will need to pass this exam.
This blog will explain what happens during a DOT physical, what to expect before and after the exam, what a passing score means, and who performs the exam.
What Does the CDL Physical Exam Consist of?
To be eligible for a DOT physical, you must be at least 18 years old and have a valid driver’s license. In addition, you will need to provide your Social Security number and complete a medical questionnaire. At least one year must have elapsed since your last DOT physical.
The medical exam has two parts: the first part is a medical history questionnaire that you will have to fill out during your visit. During the second part, which takes place about 30 minutes, the doctor will conduct a physical examination of the driver. This will include a review of your medical history, a general physical examination, and a vision and hearing screening. The doctor may also order additional tests, depending on your individual medical history.
Key Requirements for Passing a DOT Physical
In order to pass the DOT Physical and get a Medical card, commercial drivers must meet the standards from 49 CFR §391.41 (Physical qualifications for drivers), which is the federal rule medical examiners use. This certification is valid for two years. If you fail the DOT physical, you must wait at least 14 days before you can retake it. The standards are as follows from 49 CFR §391.41:
Vision (minimum standard)
Distant visual acuity: at least 20/40 in each eye (with or without corrective lenses, depending on the specific standard language). Field of vision: at least 70 degrees in each eye (horizontal meridian)Color recognition: able to recognize the colors of traffic signals and devices (red, green, amber)
Hearing
You must be able to hear a forced whispered voice in your better ear at not less than 5 feet, with or without a hearing aid; if you fail that, the examiner may require formal audiometry testing.
Blood pressure / hypertension (certification depends on control)
High blood pressure does not always mean automatic failure, but uncontrolled hypertension can limit certification length, and very high readings can be disqualifying until controlled (FMCSA guidance outlines the stage-based approach).
Diabetes
Diabetes isn’t an automatic disqualifier, but it must be stable and safely managed (especially if insulin is involved). Medical examiners evaluate risk of sudden incapacitation and may require additional documentation.
Cardiovascular health
No heart condition likely to cause fainting, shortness of breath at rest/minimal exertion, chest pain, or sudden incapacitation while driving.
Respiratory health
No lung or breathing condition (including sleep-related breathing disorders) that would likely interfere with safe driving due to fatigue or low oxygen.
Neurological health (seizures, strokes, etc.)
No neurological condition likely to cause loss of consciousness, impaired coordination, or impaired judgment while driving.
Mental health and cognition
No mental, nervous, or psychiatric condition that would likely impair attention, decision-making, impulse control, or safe vehicle operation.
Substance use
No current clinical diagnosis of alcoholism and no illegal drug use that would impair driving (separate employer DOT drug testing is a different program, but the medical standard still applies).
Musculoskeletal / limb function
You must be able to perform the physical tasks of commercial driving (climbing, coupling, steering control, etc.). Certain limb impairments may require a Skills Performance Evaluation (SPE).
Medications
Medications aren’t automatically disqualifying, but they cannot have side effects (like sedation, dizziness, impaired coordination) that would make driving unsafe; examiners may request a treating-provider statement.
The Role of DOT Physicals in Ensuring Road Safety
There are several reasons why the DOT requires a physical exam for commercial drivers. First, driving a large vehicle is more dangerous than driving a typical vehicle. If drivers are not physically able to operate the commercial vehicle, they are putting their passengers’ lives in danger. Additionally, some physical conditions impair one’s ability to drive safely. For example, diabetes can make it difficult for commercial drivers to notice when their blood sugar levels are too low or too high while on the road. A DOT physical can help identify these risks and keep commercial drivers safe while on the road.
The DOT physical is also used to ensure drivers are physically able to complete the duties of the job. Driving a truck for hours at a time, often in difficult conditions, can be strenuous. The DOT physical tests for things like vision, hearing, and reflexes – all of which are important for safe driving.
Finally, a DOT physical is a step towards receiving a commercial driver’s license. The DOT issues the medical card as proof of receiving a passing result on the exam to CDL applicants.
Preparing for Your DOT Physical: Tips and Guidelines
Preparing for your DOT physical is essential for commercial drivers to ensure a smooth and successful examination. First and foremost, gather all the necessary documents and medical records required by the Department of Transportation (DOT). These may include a list of medications you’re currently taking, a history of any medical conditions, and any relevant test results. Double-check that your documents are up-to-date and neatly organized to expedite the process.
Next, be mindful of your health and well-being leading up to the examination. Get a good night’s sleep and avoid consuming excessive caffeine or stimulants on the day of the physical. Also, remember to stay hydrated and eat a balanced meal before the appointment. This will help ensure accurate test results and give you the best chance of passing the examination. Lastly, arrive at the appointment with enough time to spare, so you’re relaxed and not rushing through the process. Following these tips and guidelines will not only make the experience less stressful but also increase the likelihood of receiving a favorable outcome for your DOT physical, keeping you on the road and your career on track.

Getting a DOT physical is one of the first steps to getting your CDL. The physical is not required to start training. However, it will make the first week of training less stressful and ensure that you meet the physical requirements to operate a commercial vehicle.
How Much Does a DOT Physical Cost?
The cost of a DOT physical typically ranges from $50 to $150, depending on the medical provider and your location. Some clinics may charge more if additional tests are required to assess your fitness for driving.
Do I Have to Pay for My DOT Physical?
The cost of your DOT physical exam can vary depending on where you get it done. In most cases, the driver is responsible for paying for their own DOT physical, but some employers or CDL training programs may cover the cost as part of their benefits package. It’s a good idea to check with your training provider or employer to see if they offer any assistance with the exam fees. Generally DOT physicals are no covered under insurance.
Does Age Play a Role in the DOT Physical?
Age does not directly affect the DOT physical requirements, as all drivers must meet the same health and safety standards to ensure they can safely operate a commercial vehicle. However, as you get older, certain health conditions that are more common with age, like high blood pressure or vision changes, could impact your ability to pass the exam. It’s important to manage your health conditions and stay up-to-date with regular check-ups to maintain your DOT medical certification.
How to Pass a DOT Physical with Common Health Conditions
Passing a DOT physical with common health conditions like high blood pressure, diabetes, or sleep apnea is possible with proper management and preparation. To increase your chances of passing, make sure to take your prescribed medications as directed, maintain a healthy diet, stay physically active, and follow your doctor’s recommendations for managing your condition. If you have a medical condition, bring all relevant medical records and documentation to the exam to show that it’s well-managed and under control.
Keep in mind that certain DOT disqualifying medical conditions do exist. It’s important to address these conditions with your healthcare provider to explore treatment options that may help you meet the requirements.
