What may cause danger to others in road traffic?

Answer: B — Driving a POV While Intoxicated

Driving while intoxicated most directly creates danger for others because alcohol or drugs impair judgment, vision, coordination, and reaction time. When a driver is intoxicated, they’re less able to judge speeds and distances, miss hazards, drift out of lanes, and react too slowly to unexpected situations. That combination raises the likelihood of crashes that can injure or kill people nearby. Fatigue can also be dangerous because it slows reaction times and attention, but intoxication tends to cause broader and more immediate impairment, making it the strongest hazard among the options. Wearing a seatbelt is protective, so it doesn’t pose a danger in itself. A disabled vehicle with warning devices not placed far enough away is a safety/setup issue that can create a hazard, but it’s not about the driver’s impaired operation in traffic like intoxication.
