What is the purpose of hazard lights on a vehicle?

• A. Indicate you are turning left or right
• B. Illuminate the road ahead
• C. Warn other drivers that your vehicle is not operating properly
• D. Show your speed to following drivers

Answer: (C)

Hazard lights are meant to warn other drivers that your vehicle is a problem or is posing a hazard. When you turn them on, all four indicators flash to grab attention and signal that you may be stopped, stalled, or moving slowly in a way that could create a risk for others. This is different from turn signals, which communicate a specific intended direction, and from headlights, which illuminate the road ahead. Hazard lights should be used in situations like a breakdown, a collision, or when you’re safely stopped on the roadway to alert approaching traffic. They aren’t used to show your speed or to replace proper signaling for turns. After you’ve reached a safe spot or the hazard is cleared, switch them off.
