Although you can search our website for specific topics and information that may affect your DOT exam, here is a list of some of the most frequently asked questions that we hear from commercial drivers regarding their DOT exam regarding their specific health issues and their certificates.
Can a driver who is an INSULIN-TREATED DIABETES MELLITUS (ITDM) patient be qualified to drive?
Effective November 18, 2018, a driver who is ITDM can be qualified to drive for up to 12 months with form MCSA-5870 filled out by your treating physician. At this time the form has not been posted on the FMCSA site and as soon as it is, we will post a link to the form. With this new approval, it is no longer necessary for ITDM patients to obtain a diabetic waiver. If you are a ITDM patient please bring the completed ITDM form from your treating physician as this will expedite your getting approval for driving.
My partner tells me I snore, will this disqualify me from driving?
The short answer is “no”. However, If you neck size is 17 inches or larger (16 inches for females) and /or your BMI is 35 or greater and / or upon visual inspection your tongue obstructs your throat, you may have obstructive sleep apnea and will be required to have a sleep study done to determine IF you have obstructive sleep apnea. If the test comes back positive, then you will be required to use a CPAP machine. (If your test is negative, please bring that result to your examination so it can be documented.) For your examination, you will need to take the chip out of the machine or take the machine to a qualified center (doctors office, DME company, etc) and have the report printed out and presented to the DOT examiner. The report must should at least 70% compliance of use for the previous 30 days.
I wear contacts, will that prevent me from being qualified?
No. Please make sure that if you do wear glasses (or contacts) please bring them to the examination. Your vision must be at least 20/40 in each eye and both eyes.
What blood pressure is required to pass the DOT exam?
A driver with a BP of less than 140 / 90 may be medically certified to drive for a two-year period.
A driver with a BP of 140 – 159 systolic and /or a BP of 90-99 diastolic, has stage 1 hypertension, and may be medically certified to drive for a one-year period. Certification examinations should be done annually thereafter and should be at or less than 140/90.
A driver with a a BP of 160-179 systolic and/or a BP of 100-109 diastolic, has stage 2 hypertension, and is a candidate for antihypertensive drug therapy. The driver is given a one-time certification of three months to reduce his or her blood pressure to less than or equal to 140/90. Provided treatment is well tolerated and the driver demonstrates a BP value of 140/90 or less, he or she may be re-certified for one year from the date of the initial exam. The driver is certified annually thereafter.
A driver with a BP at or greater than 180 systolic and / or 110 diastolic has stage 3 hypertension and is disqualified. The driver may not be qualified, even temporarily, until blood pressure is reduced to equal to or less than 140/90 and treatment is well tolerated. The driver may be certified for 6 months and biannually (every 6 months) thereafter if at recheck BP is equal to or less than 140/90.
What if I am taking medication to reduce my blood pressure?
Taking blood pressure medications will not disqualify you from the DOT exam. It will, however, limit you to a maximum of one year. Each year you will need to be re-evaluated and as long as your blood pressure is 140/90 or below, you may be re-certified for a maximum of one year.
If your blood pressure is above 140/90, you may qualify for a one time three (3) month certificate.
What are the vision requirements for passing the DOT exam?
(If you wear glasses or have a restriction on your license that you must wear glasses to operate a motor vehicle, make sure you bring your glasses to your examination.)
You must have a distant visual acuity of at least 20/40 with or without corrective lenses:
see at least 20/40 with both eyes together
see at least 20/40 with the right eye
see at least 20/40 with the left eye.
Monovision is a disqualification. Use of a contact lens in one eye for distant visual acuity and another lens in the other eye for near vision is not acceptable, nor are telescopic lenses acceptable for driving a commercial motor vehicle.
Exemption: A driver with monocular vision may be able to get a Federal Vision Exemption Certificate, if medically fit for duty in all other categories of the physical exam.
Are contact lenses acceptable for the DOT vision exam?
Yes, you may wear contact lenses for the vision portion on the exam. You will have a restriction on your certificate that requires you to wear corrective lenses while driving.
What if I have had corrective surgery for my vision such as LASIK; can I still pass the vision exam?
Yes, provided your vision is at least 20/40 in both eyes. Peripheral vision of at least 70 degrees and the ability to recognize the colors of a traffic light.
I recently had a heart attack (myocardial infarction MI) can I still be qualified to drive?
You will need to be off work for at least two months. You will need to get an Ejection Fraction and Exercise Tolerance Test, and be cleared by your cardiologist before returning to work. This is a disqualifying medical condition, so once it is resolved, and before resuming operation of a CMV, you are responsible for obtaining re-certification from a Medical Examiner.
What if I have had heart by-pass surgery: can I still pass my DOT exam?
You will need to be off work for at least three months. You will need to get an Ejection Fraction and Exercise Tolerance Test, and be cleared by your cardiologist before returning to work. This is a disqualifying medical condition, so once it is resolved, and before resuming operation of a CMV, you are responsible for obtaining re-certification from a Medical Examiner.
What if I have had stents or angioplasty? Can I still be qualified for a DOT position?
You may return to work once you’ve been cleared by your cardiologist, which may be as soon as one week after the procedure. You will need to get an Exercise Tolerance Test three to six months after the procedure, and again at least every other year. This is a disqualifying medical condition, so once it is resolved, and before resuming operation of a CMV, you are responsible for obtaining re-certification from a Medical Examiner.
Am I disqualified if I have a defibrillator?
The defibrillator is a disqualifier for inter-state driving. The defibrillator is designed to correct problems when they occur, but it still leaves a safety risk.
You may be able to drive inter-state, based on your state’s regulations.
What are the hearing requirements in order to pass the DOT exam?
The driver must be able to perceive a forced whispered voice in one ear, the better ear, at not less than five feet with or without the use of a hearing aid. If the driver fails the whisper test, the medical examiner will refer the driver to have an audiometry test. The driver must pass an audiometer test before the medical certificate can be considered.
What if I cannot hear a forced whisper within five (5) feet and have to wear hearing aids, can I still qualify for a DOT card?
Yes, as long as you can perceive a forced whispered voice in one ear, the better ear, at not less than five feet with or without the use of a hearing aid. If you use a hearing aid for the DOT physical, then you must wear that hearing aid and have it in operation at all times while driving. Also, you must be in possession of a spare power source for the hearing aid while driving.
Does sleep apnea disqualify me from a DOT card?
Sleep apnea does not necessarily disqualify you for medical certification. Treatment with a CPAP machine and some basic lifestyle changes can help you get a restful sleep and maintain your commercial driver’s license. Many drivers who have suffered fatigue for a long time , and then were diagnosed with sleep apnea and treated, report that they’ve felt like a new person since they’ve been on a CPAP machine.
If you do use a CPAP machine, you will need to download the report from the machine showing that you have used it a minimum of 70% for the previous 30 days. So please bring the report with you at the time of your exam. There maybe a chip in the back of the machine which will need to be read by the individual or company from whom you got your CPAP. If unsure, please call the manufacturer and ask how to retrieve your usage report for a DOT exam.
You will need to bring a medical opinion letter from your treating physician before you can be considered for DOT medical certification.
Is narcolepsy a disqualifier?
Narcolepsy is a disqualifier regardless of treatment, because it poses a risk of EDS (Excessive Daytime Somnolence or Sleepiness) and may also bring on sudden muscular weakness.
Can a driver with lung disease be qualified for a DOT card?
The medical examiner will evaluate your condition to determine how the lung disease may affect your ability to safely drive and perform other duties of a commercial driver. If you don’t have a medical opinion letter from a treating physician, you may need to go for a chest x-ray or pulmonary function tests before the medical examiner can consider certification.
Can I be qualified if I use oxygen therapy?
Most likely, yes, oxygen therapy while driving is a disqualifier. The reasons are twofold: 1. Malfunction of the oxygen equipment. 2. Progression of the disease may be debilitating. You may be considered if you can pass a pulmonary function test.
If your pulmonary testing with within normal limits (forced expiration volume (FEV1) is better than 65, then you may be qualified to drive.
Is COPD a disqualifier for the DOT card?
If oximetry is less than 92% (oximetry equals 70), the driver must have an ABG analysis.
Recommend not to certify the driver when ABG measurements reveal:
Partial pressure of arterial oxygen (PaO2) less than:
65 millimeters of mercury (mm Hg) at altitudes below 5,000 feet.
60 mm Hg at altitudes above 5,000 feet.
Partial pressure of arterial carbon dioxide (PaCO2) greater than 45 mm Hg at any altitude.
I had lung surgery and a lobectomy; will this be an issue for a DOT health card?
In and of itself, the lobectomy should not be an issue. But what was the reasoning behind the surgery? Your examiner will have other questions regarding the surgery and what its long term effects are, as well as, how it affects your ability to operate a commercial motor vehicle.
Is a diagnosis of Meniere’s Syndrome a disqualifying health issue?
Yes. Meniere’s disease is disqualifying because it may bring about a severe condition of vertigo and is unpredictable. The risk here is sudden incapacitation.
What are the guidelines regarding a seizure?
Drivers who have had one unprovoked seizure by definition do not have epilepsy (2 or more unprovoked seizures). Drivers who are seizure-free and off anticonvulsant medication(s) for at least 5 years after a single unprovoked seizure can be certified. Earlier return to work may be considered for drivers with a normal EEG who have no epileptic-form activity and normal examination by a neurologist specializing in epilepsy. (This is directly from the FMCSA website.)
If I take my anti-seizure medication can I still get a DOT health card?
No. Taking antiseizure medication is a disqualifier.
I have epilepsy, can I qualify for a DOT health card?
Medical diagnosis of epilepsy is disqualifying. You may be able to be granted an exemption by having your treating physician provide information about your case AND applying for an exemption with the FMCSA.
I had a stroke can I still pass a DOT physical?
It depends on many things, including the likelihood of having another stroke. Your best bet is to first go back to your neurologist and have him/her write a medical opinion letter stating:
1. When you had the stroke.
2. What was the treatment, and how successful was the outcome.
3. What is the treatment you are receiving now.
The doctor’s medical opinion about your readiness to return to work as a driver. Make sure that he/she knows all of your physical daily activities as a commercial driver.
With that information in hand when you go to do your DOT medical examination, then the DOT examiner has all the appropriate information to determine your physical state of fitness to perform the duties of a commercial driver.
I take anti-depressants can I still get a DOT card?
It’s not out of the question, but what you will need to do is get a medical opinion letter from your treating physician that states:
1. When you were diagnosed with the condition?
2. What treatment program does he/she have you on?
3. Is the condition stable?
Does your physician feel you could do the duties of a commercial driver and be safe for yourself and the people/public around you?
Then take that information the DOT physical appointment. It will still be the DOT medical examiner’s decision whether or not to certify you.
