When are headlights required to be used?

Answer: B — During low visibility conditions

Headlights are required to be used during low visibility conditions for several reasons. When driving in situations such as fog, heavy rain, snow, or dust, visibility can be significantly reduced, making it difficult for both the driver to see the road and for other drivers or pedestrians to see the vehicle. Turning on headlights in these conditions helps illuminate the road ahead and increases the visibility of the vehicle to others, thereby enhancing safety for everyone on the road. While it is true that headlights are typically used at night, relying solely on nighttime usage overlooks the crucial need for enhanced visibility during the day when conditions are poor. Although headlights may be needed when entering tunnels or when the vehicle is in motion, these situations are more specific and do not encompass the broader requirement of using headlights in low visibility conditions.
