What is the minimum visibility required to use your headlights?

The requirement to use headlights when visibility is less than 1,000 feet is based on promoting safety for both the driver and other road users. Low visibility conditions, such as fog, rain, or snow, significantly hinder the ability to see other vehicles, pedestrians, and road signs. By mandating the use of headlights in these situations, the rules aim to enhance visibility for the driver and make the vehicle more conspicuous to others, thereby reducing the risk of accidents.

Other options suggesting alternative visibility distances do not align with the guidelines that focus on ensuring drivers use their headlights early enough to react to obstacles, road conditions, and traffic. The option about driving at night only neglects other critical scenarios where visibility can be severely impaired, such as during adverse weather conditions, regardless of the time of day. Thus, using headlights in conditions where visibility is less than 1,000 feet helps maintain safe driving standards.
