(VERIFIED ANSWERS) |AGRADE

A driver has loss of hearing in the better ear of 25 dB loss at 500 Hz, 40

dB loss at 1000 Hz, and 60 dB loss at 2000 Hz. With respect to the

hearing requirement for medical certification, the driver __________.

May be certified for one year.

May be certified for two years.

May not be certified.

May be certified if examined by an otolaryngologist who is familiar with

the CMV driving duties who certifies the driver as medically qualified to

drive a CMV. - ANSWER- May not be certified.

Explanation: An average hearing loss of 41.7 decibels averaged across

500, 1000, and 2000 Hz in the better ear is disqualifying. The driver

should be referred to obtain a hearing aid and may be certified if the

driver passes while wearing a hearing aid. A specialist cannot determine

certification, and a specialist cannot override medical qualification

standards such as the minimum hearing requirement.

Which of the following is acceptable for a driver who wears a hearing

aid?

Testing of the driver's hearing is waived if the driver presents a letter

from a qualified specialist.

Testing of the driver's hearing may be performed by the medical

examiner using audiometric testing equipment.

Testing of the driver's hearing may be performed by an audiologist or

otolaryngologist using specialized audiometric testing equipment.

Testing of the driver's hearing may be performed at 1,000 Hz only. -

ANSWER- Testing of the driver's hearing is waived if the driver

presents a letter from a qualified specialist.

Explanation; Testing the hearing of a driver who wears a hearing aid

may be accomplished in three ways: 1) whisper test, 2) audiometric

testing by an otolaryngologist using specialized audiometric testing

equipment, or 3) audiometric testing by an audiologist using specialized

audiometric testing equipment. Audiometric testing is required to be

conducted at 500 Hz, 1000 Hz, and 2000 Hz.

Passing Requirements for Vision Tests - ANSWER- Corrective lenses,

eye glasses and/or contact lenses may be used.

Explanation; Distance binocular acuity of at least 20/40 (Snellen) in

each eye with or without corrective lenses. Field of vision of at least 70º

in the horizontal meridian in each eye. Monocular vision - vision

meeting requirements in only one eye - is disqualifying by regulation.

The ability to recognize the colors of traffic signals and devices showing

standard red, green, and amber.

Contact lenses that correct vision in one eye for distance and the other

eye for near are not acceptable.

Results must be converted to Snellen values if another test is used.

Measured in each eye individually and both eyes.

Drivers who wear corrective lenses should be advised to carry spare

glasses.

In general, any vision condition, such as lazy eye, glaucoma, cataract,

and others, is not disqualifying as long as the driver meets minimum

vision testing parameters.

FMCSA is - ANSWER- Federal Motor Carrier Safety Administration. Is

overseen by the DOT. The FMCSA creates standards for driver

examinations. Regulates Interstate commercial operations, including the

driver.

Many states use federal FMCSA standards to govern intrastate

commercial operations, including the driver, but the FMCSA does not

directly regulate any intrastate functions.

a division of the US Department of Transportation (DOT).

can be considered on a case-by-case basis include __________.

Autonomic neuropathy.

Methadone use.

Monocular vision.

Carpal tunnel syndrome. - ANSWER- Correct Answer: Autonomic

neuropathy.

Explanation; Methadone use and monocular vision are always

disqualifying. Carpal tunnel syndrome is not usually disqualifying.

A driver experienced a pneumothorax four weeks ago. The medical

examiner tests the driver's respiratory function and the forced vital

capacity (FVC) is 58% of predicted. What should the certification

decision be?

Do not certify pending additional testing.

Certify for three months, pending driver follow up with personal

physician and/or specialist.

Certify one year.

Certify two years. - ANSWER- Correct Answer: Do not certify pending

additional testing.

Explanation: The driver may not be certified until FVC is > 60%

predicted or additional testing reveals acceptable respiratory parameters

- e.g., pulse oximetry with O2 > 92%.

Stage 1 Hypertension Two certification options: - ANSWER- One Year:

recommend to certify for one year if it is the first examination at which

the driver has blood pressure equivalent to Stage 1 hypertension, and the

driver has no history of hypertension and does not use medication for

blood pressure control.

Three Months: recommend to certify for a three month certification if

the driver has been given a one-year certificate for untreated Stage 1
