DOT Exam 2023 Questions with 100%
Correct Answers25
Exam Order - ANSWERS-1. General 2. Skin 3. Eyes 4. Ears 5. Mouth/Throat 6. Cardiac 7.
Lungs/Chest 8. Abd 9. Genitourinary/Hernia 10. Back/Spine 11. Extremities/Joints 12.
Neuro/Reflexes 13. Gait 14. Vascular
Eye Assessment - ANSWERS-pupilary accomidation/reactivity to light, nystagmus, extra ocular
movements. Prosthetic eye disqualified.
Ear Assessment - ANSWERS-TM must be viewed! (If wax blocking, put determination pending
until wax removed).
Assess for scarring of TM, occlusion of ear canal, or perforated ear drums.
UA disqualifying? - ANSWERS-Abnormals NOT disqualifys, just refer to PCP
SP Gravity Normal - ANSWERS-1.005-1.030
Protein Abnormal UA - ANSWERS-+, indicates kidney issues
Sugar UA: - ANSWERS-+, check blood glucose & refer to PCP
Hearing Exam Requirements - ANSWERS-Must perceive whispered voice at no less than 5 ft in at
least 1 ear. OR average hearing loss of </= 40 dB in better ear (w or w/o hearing aid).
,Forced Whisper Test Instructions - ANSWERS-1st perceives forced whisper in one ear. Cover
opposite ear. Stand to side or behind pt. From 5', exhale fully and whisper a sequence of words
or #s. Avoid S-sounding words. Ask driver to repeat.
Failed whisper Test - ANSWERS-then precede w/audiometric test. However, if failed w/hearing
aid: refer to audiologist, otolaryngologist, or hearing aid center.
Audiometric test measurements - ANSWERS-measured at 500, 1000, 2000 Hz. Average must be
</=40. ANSI Standard.
Ear Dx's Disqualified - ANSWERS-Uncontrolled vertigo, Meniere's disease, labyrinthine fistula, &
nonfunctioning labyrinths.
Vision Screening Requirements - ANSWERS-Must have at least 20/40 in each eye. And at least
70*(or +) field of vision in horizontal meridian in each eye.
Distinguish between red, green, & amber colors. Doesn't matter color seen, as long as they can
differentiate between them.
Monocular Vision - ANSWERS-In better eye, distant visual acuity of at least 20/40 (w or w/o
corrective lenses) & field of vision of at least 70* in horizontal meridian &
In worse eye, either distant visual acuity of less than 20/40 w/corrective lenses or field of vision
of less than 70*, or both.
To certify: vision deficiency must be stable, and have sufficient time pass to adapt
to/compensate for change in vision, & must be able to recognize red, green, & amber
Cataracts - ANSWERS-slow, progressive opacification of lens of eye distorts optical passage of
light to the retina resulting in diminished visual acuity. Formation can be accelerated by injury,
exposure to radiation, gout, steriods, & DM. Glare, particularly during night driving in face of
oncoming headlights, might be an early symptom. Glare, diminished overall acuity, contrast, &
color resolution. Sx tx.
, Glaucoma - ANSWERS-Development of chronic elevated intraocular pressure is generally
painless, & gradual loss of peripheral vision can progress before symptoms noticed. May affect
redirection of visual attention, night vision, & color vision. Snellen acuity may not be affected.
Vision loss cannot be restored. Goal is to lower intraocular pressure to prevent further loss of
visual deficit. Tx: eye drops.
Macular Degeneration: - ANSWERS-describes many ophthalmic diseases that impact macula fxn
and interfere with detailed, central vision. Usually slow process resulting in subtle visual deficits.
Peripheral vision generally spared. Therapeutic options limited. Visual acuity drops, recovery
from bright lights is lengthened, & eventually a partial or total scotoma develops in direction of
attempted gaze. Snellen test will detect diminishing central acuity. Use of telescopic lenses is
not acceptable for commercial driving.
Retinopathy - ANSWERS-Noninflamatory damage to retina. Commonly d/t DM. Fluid leakage
near macula can create partial scotomas in central vision or cause gross hemorrhage in eye and
obscure vision and eventually lead to retinal detachment & blindness. Subtler visual modalities
such as contrast sensitivity, flicker fusion frequency, & color discrimination may be affected.
Diabetics treated with insulin are disqualified if they have severe non-proliferative retinopathy
or proliferative diabetic neuropathy.
BP >139/89 - ANSWERS-Repeat
Stage 1 HTN - ANSWERS-140-159/90-99
Cert 1 yr.
At recert: BP <140/90 may cert 1 yr or >140/90 but <160/100 certify 3mon's.
Classify HTN by - ANSWERS-Higher #
Stage 2 HTN: - ANSWERS-160-179/100-109.
Refer for tx, 3 month cert. Reexamine & certify for 9 mon's from today. <140/90 may certify 1 yr.
