According to FMCSA regulations, which of the following must the medical examiner evaluate when examining a driver's eyes? A. Pupil reactivity B. Iris symmetry C. Conjunctival injection D. Corneal thickness - correct answers ✅Correct Response: A. Pupil reactivity Incorrect Responses: B. Iris symmetry This is incorrect because determining iris symmetry is not required by FMCSA. C. Conjunctival injection This is incorrect because most causes of conjunctival injection would not be disqualifying. Causes that are suspicious for a disqualifying condition need additional evaluation. While this abnormal finding should be explained, with determination of possible effects on safe driving before making a certification decision, it is not a condition that is specified in FMCSA regulations.

This is not the correct response because drivers with hypertension are only given a medical certificate that is good for one year. C. A recent diagnosis of Lewy body dementia. This is not the correct response because this is a progressive, degenerative condition with no known treatment. The effects of Lewy body dementia impact the ability to operate a CMV safely. D. Documented medical marijuana use for pain control. This is not the correct response because marijuana remains a drug listed in Schedule I of the Controlled Substances Act. It remains unacceptable for any safety-sensitive employee subject to drug testing under the drug testing regulations of DOT to use marijuana. Also, FMCSA medical guidelines state that "driving impairment due to marijuana use is well substantiated."

Every year / Every year B. Every two years / Every year C. Every year / Every two years D. Every two years / Every two years - correct answers ✅Correct Response: C. Every year / Every two years This is the correct response because according to FMCSA medical guidelines, when a myocardial infarction is part of the medical history, there is a significant increased risk for another myocardial infarction to occur within six months to a year; therefore, a maximum of one-year certification is the guideline.

tolerance testing at least every two years to demonstrate continued ability to safely operate a CMV. Incorrect Responses: A. Every year / Every year This is not the correct response because the FMCSA medical guidance is to obtain an exercise tolerance test every two years. In this question, there is nothing to indicate that more frequent testing is necessary. B. Every two years / Every year This is not the correct response because it reverses the guidelines. Even if you do not recall the recommendation, logically, one would eliminate this option because having the driver obtain a test every year and then waiting for up to a year to review the test results is not reasonable when unacceptable test results indicate the driver may not be able to safely operate a CMV. D. Every two years / Every two years This is not the correct response because the guideline is to recertify every year. Even if you do not recall the actual guideline, one would logically eliminate this option because this is the maximum recertification period for a driver who meets all qualification requirements.

Temporarily disqualified until further evaluation. This is the correct response because the driver has a non-diagnosed respiratory or thoracic illness that might interfere with the ability to safely operate a CMV. The driver should not be certified until the etiology is confirmed and treatment has been shown to be effective, safe, and stable. Also, according to FMCSA medical guidelines, a SpO2 of less than 92 percent warrants obtaining an arterial blood gas analysis.
