When is it permissible to use hazard lights while driving?

• A. When your vehicle is disabled or stopped on the roadway to warn other drivers; not for general caution.
• B. Anytime you are driving slowly.
• C. To indicate lane changes.
• D. To signal to other drivers that you are in a hurry.

Answer: (D)

Hazard lights are there to warn other drivers when your vehicle has a problem or is stopped on the road. Activating them signals that you’re not just quietly slowing down, but that your car is a potential obstacle and that drivers should proceed with extra caution. Because of that purpose, they’re best used when you’re disabled or safely stopped, such as on the shoulder or after a breakdown. They should not be used as a general caution signal, to indicate a lane change, or to show that you’re in a hurry. For lane changes, rely on your turn signals, and for situations where you’re moving slowly for a reason, stick to normal driving signals and safe following distances rather than hazard lights.
