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

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

Answer: (C)

Hazard lights are used to alert other drivers that your vehicle is a stationary hazard and to make you more visible. When a car is disabled or pulled over, these lights flash to warn approaching traffic to slow down and pass with caution, reducing the chance of a crash. They help drivers see you from a distance or in low-visibility conditions, not just pedestrians. They don’t indicate an intent to move immediately—that’s what turn signals are for—nor are they a signal that you’re about to turn. Use them whenever you’re stopped in a way that could create danger for others, such as on the side of the road or in traffic, to communicate the hazard to every road user.
