Under what conditions must you use headlights during the day?

Using headlights during the day is particularly important when visibility is less than 1,000 feet. This is because low visibility conditions, such as fog, heavy rain, or snow, can make it difficult for other drivers to see your vehicle. Headlights help increase the visibility of your car, making it safer for both you and others on the road. In situations where light conditions are poor, drivers are encouraged to turn on their headlights to ensure they can be seen clearly.

While headlights are certainly required at night and may also be used in specific weather conditions like rain, the emphasis here is on the critical importance of visibility for safety purposes. Not all scenarios where headlights are needed during the day relate directly to the speed of travel or solely to the presence of rain; the overarching concern is ensuring that visibility standards are met for safe driving.
