If you want to drive large commercial vehicles for a living you’ll need a CDL (commercial driver’s license) and a valid DOT medical card. This card can only be obtained once you have successfully passed a DOT physical, which you’ll need to have again every 1-2 years for the duration of your career.

Finally, A Better Way to Manage DOT Physicals 
While the process of getting your DOT physical and medical card is straightforward, many people feel confused about the requirements they have to meet to pass. Below, we’ll talk you through each aspect of the physical, what standard you need to meet to pass, and links to further resources where you can find out more about the requirements for each element of the DOT medical exam.

What is a DOT physical?
The DOT (Department of Transportation) physical is a medical examination you must undergo before being permitted to drive commercial vehicles for a living. This physical ensures you are fit enough to meet the demands of your job and can operate large vehicles or vehicles with passengers without putting yourself or anyone else at risk.

Do I need a DOT physical?
You are required to have a DOT physical exam if:

You transport hazardous materials You operate a vehicle that carries more than 15 people You are paid to operate a vehicle that carries more than 8 people You operate a vehicle with a gross combined weight of more than 10,000lbs

What does the physical exam consist of?

The DOT exam will include the following:

Physical examination - The doctor will check your eyes, ears, mouth, throat, heart, lungs, abdomen, spine, extremities, and neurological system for signs of any potential problems, impairments, or injuries. Vision test - While you don't need perfect 20/20 vision to pass a DOT physical, you will need to have a minimum 20/40 visual acuity in both of your eyes, even with contact lenses or glasses. You will also need a minimum peripheral vision of 70" in both of your eyes. Hearing test - You must be able to hear a "forced whisper" from five feet away, with or without hearing aids. Blood pressure check - Many people wonder, "Can you pass a DOT physical with high blood pressure?" The answer is yes, but only if it is below a certain limit. You can find out the current limitations in this Foley blog article. Urine test - While many assume the urine test in a DOT physical is a drug test, it doesn't check for drug use. The DOT physical urine test is simply to look for underlying conditions, such as diabetes. Sleep apnea test - If you report having symptoms such as drowsiness during the day, headaches in the morning, gasping while sleeping, or heavy snoring, you may need to undergo a sleep apnea test.
As well as a range of other health indicators that can indicate that there is a problem that may put you at risk while operating a commercial vehicle.

How do I prepare for a DOT physical?
If you’re fit and in good health, there’s very little you need to do to prepare. The DOT exam is simply a check-up by a doctor to ensure you are fit enough to operate such a large vehicle.

If you’re overweight, are recovering from a bigger health issue, or are having a serious health issue managed by a doctor, you may want to make additional preparations. Whether or not you need to make any changes before your CDL DOT physical or bring anything with you will depend on your circumstances and current level of health.

If you are currently managing any health issues, make sure your prescriptions and medications are up to date, you’ve recently had a vision test and have the right corrective eyewear, and the same for your hearing if you suffer from hearing loss.

It’s good practice for anyone getting ready for their DOT physical to cut back on processed foods, alcohol, and smoking to ensure they’re in good health at the time of their physical.NEW CSA Score Webinar - Reserve Your Spot Now!

What are the DOT physical requirements?
Vision Requirements
To pass the vision test, you need to have 20/40 vision in each eye either with or without glasses, a field of vision of 70 degrees or more in each eye, and be able to differentiate between red, green, and amber.

If you do not meet these standards but meet all other standards of the DOT Physical, you may be able to apply for an exemption.

Hearing Requirements
To pass your hearing test, you must be able to hear a harsh whisper in your best ear, at no less than 5 feet, with or without a hearing aid. If you fail this basic hearing test, you’ll be referred for an audiometry test which will further determine if you are safe to drive.

In most cases, you’ll be able to get a hearing correction device and then pass your DOT physical. If you need a hearing aid, you must wear it at all times while driving.

You’ll only fail the hearing test if you are completely deaf and cannot pass the whisper test even with hearing aids.

Blood Pressure Requirements
High blood pressure is an extremely common health problem, and the DOT medical exam uses it as a key health indicator.

If your blood pressure is 140/90 or below, you’ll pass the DOT physical blood pressure requirements with flying colors. Between 140/90 and 179/109, you may need to have a medical exam more frequently or be given a temporary medical card and be asked to reduce your blood pressure within a 3-month period.

What medical conditions can impact your ability to pass a DOT physical?
There are a handful of health issues that are DOT physical disqualifying conditions, meaning that if they are out of control or too severe for you to operate a large commercial vehicle safely, you will not be able to pass the DOT physical.

These conditions are:

Diabetes Hernias High BMI (Obesity) Sleep Apnea

What do they do in a DOT physical?
Your medical examiner will first talk through your medical history with you and any ongoing treatment you have. They’ll then take your height and weight, so they can calculate your BMI, and check your blood pressure, vision, and hearing.

They’ll do a general assessment of your physical health, look at your skin, check your reflexes, and examine you for hernias.

You’ll also submit a urine sample that will be analyzed to calculate your blood sugar levels and a few other health markers.

In most cases, the DOT exam will end there and you’ll get your medical certificate. However, if your medical examiner found something they believe warrants further testing, or if the requirements of the physical demand it, you may be referred on for another test before you can get your certificate.

How much does a DOT physical cost?
The DOT physical price varies depending on where you get it, and if you are fronting the cost, or if the company you work for will cover part or all of the cost.

Do DOT physicals include a drug test?
The DOT physical does not specifically test for drugs. The urine sample you give as a part of your DOT physical checks your blood sugar levels. Some employers will require you to submit a urine sample for a DOT drug test, but the DOT physical itself will not look for legal or illegal substances.

What will make you fail a DOT physical?
If you have extremely high blood pressure, high blood sugar, an untreated hernia, or uncorrected vision or hearing, you may fail the DOT physical.

What happens if you fail the DOT physical?
Failing your medical exam is never good news, but it’s also rarely the end of your driving career. In most cases, failing your physical simply means you need to make some lifestyle changes and improve your health so you can safely get back on the open road.

Remember that the DOT physical isn’t trying to catch you out – it looks at your overall well-being and considers if you may have a major health episode in the near future that would jeopardize the safety of yourself and others. If you fail a DOT physical, work with your doctor to get your health back on track so you can get back on the road.

Where can I find the DOT physical forms?
You need to fill out a medical examination report before or when you start your physical.

Generally, the DOT physical is straightforward and nothing to worry about. The medical examiner merely needs to ensure you are fit and healthy enough to operate a large commercial vehicle.
