When should headlights be used?

Answer: B — From sunset to sunrise and during low visibility

Headlights should be used from sunset to sunrise and during low visibility conditions, which is why this choice is correct. It is essential to have your headlights on during these times for the safety of both yourself and other drivers. At night, headlights enable you to see the road and any potential hazards ahead, while also making your vehicle visible to others. Low visibility can occur not just at night, but also during adverse weather conditions, such as fog, rain, or snow. In these situations, using your headlights helps to illuminate the road and can also assist other drivers in seeing your vehicle, reducing the risk of accidents. Using headlights only in foggy conditions, only during heavy rain, or whenever driving over 30 mph does not cover the broader requirement to utilize headlights in a variety of circumstances that affect visibility. Therefore, the most comprehensive and accurate guideline is to use headlights from sunset to sunrise and whenever visibility is compromised.
