2. Which of the following is true with regard to horizontal field of vision testing?
a) Passing parameters are 75 degrees in left and right eye visual fields.
b) Medical Examiners may use a variety of methods in the clinical setting
tomeasure field of vision, including reasonably reliable and accurate tests.
c) Telescopic lenses that redirect peripheral vision to compensate for loss ofcen-
tral vision are not acceptable corrective lenses for meeting commercial driving
qualification requirements if the driver meets vision testing requirements.
d) Specialized ophthalmological equipment should not be used for precise
measurement to determine if vision meets the minimum 70º requirement.: b
- Passing parameters for field of vision are 70 degrees in left and right visual fields. Telescopic lenses that redirect
peripheral vision to compensate for loss of central vision are acceptable if the driver meets vision testing requirements,
which is a change from prior guidance. Specialized ophthalmological equipment may be used to measure vision
parameters.
3. Which of the following will always disqualify a driver from being certified?a)
Abnormal reactivity to light.
b) 70° horizontal field of vision in each eye.
c) Vision worse than 20/40 Snellen in each eye independently and both eyesto-

d) Floaters.: c - While there is an alternative qualification process for drivers with monocularvision, there is no
alternative qualification for drivers that fail to meet theminimum vision qualifications in both eyes.
