As of 2023, all drivers seeking to obtain a commercial driver's license (CDL) must meet the minimum DOT Physical BMI Requirements 2023 set by the U.S. Department of Transportation. Before being issued a CDL, applicants must present proof that their body mass index (BMI) is at or below the required level for their age and gender.

Failure to meet this requirement will result in disqualification from obtaining a CDL. Drivers found to be overweight or obese can take steps to reduce their weight before reapplying for their license. This could include:

  • regular physical activity
  • dietary changes
  • reducing daily calorie intake
  • avoiding sugary drinks
  • reducing processed food
  • eating lots of fruits and vegetables
  • monitoring portion sizes

Can I Fail a DOT Physical If I'm Overweight?

“Can you fail a physical for being overweight?” That is a common question our organization receives from US trucking professionals. Yes, you can fail a DOT physical if you're overweight. According to the FMCSA, being overweight is considered an overall health risk and can, therefore, cause failure of the medical exam. Generally, the doctor will measure your Body Mass Index (BMI) to determine whether or not you are at a healthy weight.

If it's determined that your BMI puts you in the obese range, then you may be asked to provide documentation from your primary care physician. This concerns specific medical conditions that could be causing or contributing to your obesity. Depending on the situation and any pre-existing medical conditions, it’s possible for you to still pass the physical despite being overweight. Ultimately, a certified examiner evaluates each case on its own merits.

What Does BMI Mean?

Here are the basics of what BMI means.

  • BMI stands for body mass index.
  • It measures the amount of body fat a person has based on their height and weight.
  • A healthy BMI range falls between 18.5 - 24.9 kg/m2, indicating that the person has ideal body fat.
  • A score higher than 24.9 indicates excess body fat, while lower than 18.5 suggests insufficient body fat for optimal health.
  • BMI is not a perfect system for measuring body composition as it does not take into account factors like muscle mass or age, and can overestimate or underestimate accurate levels of obesity in some cases.

Can I Calculate My BMI in Pounds Online?

Yes, you can easily calculate your BMI in pounds online. All you need to do is enter some basic information about yourself such as your height and weight into a BMI calculator. This calculator will then automatically calculate your BMI in pounds. You can find several different types of free calculators online so that you can quickly and easily determine your own BMI score.

It’s important to remember, though, that a BMI calculator should not be used as the sole indicator for whether someone is overweight or underweight. Instead, it should be used as a tool to help assess overall health by looking at other factors like diet and exercise habits, medical history, and more. If you have any concerns with your weight or health, it’s best to speak to a doctor.

What is the Highest BMI You Can Have To Pass the DOT Physical?

When it comes to BMI, it is not a measure that will disqualify you from passing your physical exam. However, if your BMI is high enough, your medical examiner may recommend a sleep study to detect sleep apnea. A BMI over 40 automatically triggers a recommendation for the test, while BMI values between 33 and 40 require additional criteria to be flagged for the test.

These conditions include being male, having neck measurements of greater than 17 inches for men or 16 inches for women, and having an increased risk of cardiovascular disease due to lifestyle choices like smoking or lack of exercise. If any or all of these are present, then a sleep study may be recommended despite the lower BMI value.

What Are the Recent BMI Requirements Regarding the DOT Physical?

Since 2016, numerous attempts have addressed the confusion around BMI and DOT physicals. In 2018, the National Transportation Safety Board (NTSB) recommended to the FMCSA that drivers with certain BMI levels should be required to undergo a sleep study as part of their certification process.

Keep in mind that recent DOT physical requirements for BMI have been defined. But please note that it is still a debated topic. Thus, the regulations can change again in the future. A medical examiner can only recommend a driver for a sleep study if he or she has a BMI of at least 40. (This is regardless of whether you have other medical conditions.) Or, a sleep study can take place if a driver has a BMI of at least 33 when three or more of these conditions are met:

  • Are a male or a post-menopausal female
  • Are aged 42 or above
  • Have Hypertension (whether treated or not)
  • You have Type 2 diabetes (whether treated or not)
  • Have a history of stroke, coronary artery disease, or heart arrhythmias
  • You have Micrognathia or retrognathia
  • Loud snorer
  • Experience witnessed sleep apnea episodes
  • Suffer from a small airway (this means reduced space at the back of the throat)
  • Have a neck size over 17 inches for males, or 15.5 inches for females
  • Hyperthyroidism

What Takes Place If I Get Recommended for an FMCSA Sleep Study?

If you get recommended for an FMCSA sleep study, the next step is to make an appointment with a qualified sleep specialist for testing. During the consultation, the specialist will review your medical history and assess your risk factors for obstructive sleep apnea (OSA). If OSA is diagnosed, the specialist will offer treatment options tailored to your specific needs. This may include lifestyle changes such as:

  • diet or exercise modifications
  • oral appliances
  • positive airway pressure therapy (CPAP)
  • surgery

Depending on your diagnosis, you will be monitored and tested again to track progress and ensure that your prescribed treatment is working properly. It’s essential to follow up with your doctor regularly so they can adjust any necessary medications or treatments.

Does Insurance Pay for the FMCSA Sleep Study?

The FMCSA sleep study can be a helpful tool for those who struggle with fatigue while driving. However, the costs associated with this testing can be daunting to some. The good news is that many insurance plans may cover at least part of the cost for the study, depending on the individual’s plan and provider.

Insurers understand that fatigue is a serious cause of motor vehicle accidents and view the FMCSA sleep study as an essential step in helping to prevent them. Therefore, they are willing to provide coverage for some or all of its associated costs. It's important to speak with your insurance provider about their specific policies regarding this type of testing, so make sure you ask lots of questions!

I'm Overweight. How Do I Pass the DOT Physical?

Here are some tips for passing an upcoming DOT physical if you are struggling with weight:

  • Visit your doctor: Visit your primary care physician for a check-up and get an understanding of any medical issues that may arise during the DOT physical. Eat healthily: Aim to eat balanced meals and avoid empty-calorie foods if you are trying to lose weight for the DOT Physical.
  • Exercise regularly: Make sure to incorporate regular exercise into your lifestyle, such as walking or jogging three times a week for 30 minutes each time. This will help you get into shape and stay healthy for the exam.
  • Stay hydrated: Drink plenty of water before and after the physical to ensure proper hydration levels during the examination process.
  • Get enough rest: Make sure you sleep well as many nights as you can before the test takes place.

  • Drivers of commercial motor vehicles (CMV) that are required to have a commercial driver’s license (CDL).
  • Drivers who operate vehicles requiring placards, such as hauling hazardous materials.
  • Any driver who is subject to the Federal Motor Carrier Safety Regulations (FMCSRs).

Where Do I Get My DOT Physical?

If you're looking for a DOT physical, there are several places to get one. Your local health department and primary care physician may be able to provide the physical. However many occupational health clinics or urgent care centers also offer physicals. You can also search for "DOT physicals near me" online to find a provider in your area.

It's important to ensure the provider is certified by the Federal Motor Carrier Safety Administration (FMCSA) to give DOT physicals. Be sure to ask about this when making your appointment. Getting a DOT physical is an important part of keeping yourself and others safe on the road, so finding a reliable provider with experience is essential. Once your DOT physical is completed, you'll receive a Medical Examiner's Certificate.
