Traffic School Module Practice Test

What are common signs of alcohol impairment visible to a driver?

Difficulty keeping your lane, slowed reaction time, poor coordination, and red or glassy eyes. Excellent balance and quick reaction time. Clear vision and steady hands. High energy and alertness.

Correct Answer:

Difficulty keeping your lane, slowed reaction time, poor coordination, and red or glassy eyes.

Explanation:

Alcohol impairment slows the central nervous system, which hurts your vision, balance, and ability to react quickly while driving. That shows up in observable ways like difficulty keeping your lane, a slower reaction to other vehicles or hazards, poorer coordination that makes steering and braking less precise, and eyes that look red or glassy. These signs come from the way alcohol dulls coordination and decision-making, and from changes in eye appearance that a driver behind you might notice. The other options describe states that would typically indicate sobriety or enhanced performance—good balance and quick reactions, clear vision and steady hands, or high energy and alertness—so they don’t match what impairment looks like.
