Drowsiness and fatigue are factors that contribute to driving risk. Which choice best describes this relation?

• A. Contributes to risk
• B. Reduces risk
• C. No effect
• D. Increases safety

Answer: (A)

Drowsiness and fatigue reduce alertness and slow your reaction time, which directly increases the chance of a crash. When you’re tired, your ability to notice hazards, make quick decisions, and respond promptly is impaired, and you may even experience brief periods of sleep while driving. That means these factors raise driving risk, not lower it or have no effect, and certainly not increase safety. So the best description is that drowsiness and fatigue contribute to risk.
