DOT Exam 2023/2024 Exam Questions
and Answers Graded A+
Exam Order - ANSWER-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 - ANSWER-pupilary accomidation/reactivity to light, nystagmus, extra
ocular movements. Prosthetic eye disqualified.
Ear Assessment - ANSWER-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? - ANSWER-Abnormals NOT disqualifys, just refer to PCP
SP Gravity Normal - ANSWER-1.005-1.030
Protein Abnormal UA - ANSWER-+, indicates kidney issues
Sugar UA: - ANSWER-+, check blood glucose & refer to PCP
Hearing Exam Requirements - ANSWER-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 - ANSWER-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 - ANSWER-then precede w/audiometric test. However, if failed
w/hearing aid: refer to audiologist, otolaryngologist, or hearing aid center.
,Audiometric test measurements - ANSWER-measured at 500, 1000, 2000 Hz. Average
must be </=40. ANSI Standard.
Ear Dx's Disqualified - ANSWER-Uncontrolled vertigo, Meniere's disease, labyrinthine
fistula, & nonfunctioning labyrinths.
Vision Screening Requirements - ANSWER-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 - ANSWER-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 - ANSWER-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 - ANSWER-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: - ANSWER-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 - ANSWER-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 - ANSWER-Repeat
Stage 1 HTN - ANSWER-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 - ANSWER-Higher #
Stage 2 HTN: - ANSWER-160-179/100-109.
Refer for tx, 3 month cert. Reexamine & certify for 9 mon's from today. <140/90 may
certify 1 yr.
Stage 3 HTN: - ANSWER->180/110.
No cert until BP <140/90 & recertify q6 mon's.
Echocardiograph: - ANSWER-LVEF should be >/= 40%
Post-MI: - ANSWER-waiting period is 3 mons
max cert is 1 yr.
Must be asymptomatic. Tolerates meds. Has a satisfactory ETT post-MI and biennial
thereafter. Resting LVEF >/= 40%.
Needs cardiovascular clearance.
