What is the purpose of hazard lights on a disabled vehicle?

• A. To signal you plan to move in immediately.
• B. To warn other drivers of a stationary hazard and increase visibility.
• C. To indicate you are about to turn.
• D. To warn pedestrians only.

Answer: (B)

Hazard lights on a disabled vehicle are for warning other road users about a stationary hazard and increasing visibility. When a car breaks down or must stop on the roadside, turning on the hazard lights signals that the vehicle isn’t about to move and that there’s a potential obstacle ahead. This prompts drivers behind and to the sides to slow down, leave extra space, and proceed with extra caution, helping prevent collisions. They aren’t used to indicate an intent to move right away, nor to signal a turn, and they aren’t just for pedestrians. The lights help maintain visibility in daytime, nighttime, and poor weather, making the stalled vehicle easier to notice from a distance.
