Explanation:

To determine the correct answer, we analyze each option:

• Option A: A mismatch between mental alertness and physical exhaustion is not the primary way fatigue increases accident risk.
• Option B: Fatigue's main impact isn't exacerbating distractions, but rather directly affecting driver capabilities.
• Option C: Fatigue does not typically impair hearing; it affects cognitive and physical responses related to driving like vision and reaction, not hearing.
• Option D: Fatigue causes tiredness which impairs vision (e.g., blurred vision, difficulty focusing) and reaction time (slower to respond to road changes), increasing accident risk.

Answer:

D. It impairs your vision and reaction time.
