New York DMV Permit Written TestAlcohol and Drug LawsMedium
Which of the following describes a key way that even small amounts of alcohol impair a driver's ability to operate a vehicle safely?
- AIt improves reaction time by acting as a stimulant.
- BIt slows down the central nervous system, affecting judgment and coordination.
- CIt enhances the ability to multitask and focus on multiple stimuli.
- DIt increases peripheral vision, leading to sensory overload.
Show answer & explanationAnswer & explanation
Correct answer: B. It slows down the central nervous system, affecting judgment and coordination.
Alcohol is a central nervous system depressant. Even small amounts slow down brain activity, leading to impaired judgment, reduced coordination, slower reaction times, and decreased ability to process information, all critical for safe driving.
Why the other options are wrong
- A. Alcohol is a depressant, not a stimulant, and it slows down reaction time, making it harder to respond to hazards.
- C. Alcohol significantly impairs multitasking and the ability to focus on multiple stimuli, making driving more dangerous.
- D. Alcohol actually narrows peripheral vision and impairs sensory processing, it does not increase it.
Alcohol as CNS Depressant
Alcohol is a central nervous system (CNS) depressant, meaning it slows down brain function, impairing judgment, coordination, reaction time, and vision necessary for safe driving.
- Affects brain and spinal cord.
- Slows down information processing.
- Impairs motor skills and balance.
- Reduces inhibitions and judgment.
Memory trick: Alcohol's 'downer' effect makes driving a frown-er.
