When is it necessary to turn on your hazard lights?

Answer: B — When your vehicle is disabled or stopped on the road

Turning on your hazard lights is essential when your vehicle is disabled or stopped on the road. This action alerts other drivers to the fact that your vehicle is not moving or is parked in a potentially dangerous position, improving safety for both you and other road users. Hazard lights signal that your vehicle requires special attention, allowing other drivers to steer clear and proceed with caution. In situations like heavy rain, while it is important to drive carefully and consider using headlights, hazard lights are not universally required. They are primarily for signaling a stopped or disabled vehicle, rather than for driving conditions. Similarly, using hazard lights at night or while merging into traffic is not typical protocol; adequate signaling with turn signals is the appropriate method in those scenarios.
