What are the three clues for DUI stimulus?

• A. Check for equal pupil size; 2) Resting Nystagmus; 3) Equal tracking (about 2 seconds out from the center to the side)
• B. Slurred speech; 3) Difficulty balancing; 4) Inconsistent handwriting
• C. Dilated pupils; 2) Eyelid tremor; 3) Headache
• D. Unequal tracking; 2) Resting nystagmus; 3) Unequal pupil size

Answer: (A)

The idea being tested is using eye signs to spot impairment during a DUI assessment. The three clues described are all eye-related cues you’d look for. First, equal pupil size helps rule out a simple asymmetry that could confuse observations; normal pupils are usually equal, so noticing equality is part of a clean eye check. Second, resting nystagmus refers to small, involuntary eye jerks seen when the eyes are looking straight ahead; this sign can appear with certain impairing substances, so it helps indicate impairment in the eye’s motor control. Third, equal tracking means both eyes move smoothly together when following a moving target, with observations focused roughly two seconds out from center toward the side; this assesses smooth pursuit and coordination. Together, these three ocular signs form a consistent set used to gauge DUI-related impairment. The other options mix in non-eye signs or different ocular findings that aren’t the same three cues used here.
