When are headlights required to be used?

1. Only at night

2. When visibility is poor or in adverse weather conditions

3. When driving in residential areas

4. Only when driving on highways

The correct answer is: When visibility is poor or in adverse weather conditions

Headlights are required to be used when visibility is poor or in adverse weather conditions. This includes situations like fog, rain, snow, or when driving through tunnels. The primary purpose of headlights in these situations is to enhance visibility for the driver and to ensure that other drivers can see them as well, thereby increasing safety on the road. While it is important to use headlights at night to ensure proper visibility, their use is not limited only to nighttime. In residential areas, headlights help illuminate the road and surrounding area, but the requirement extends beyond just driving through such zones. Additionally, headlights are also not only necessary on highways; they are crucial in all types of driving conditions where visibility might be compromised.
