When must you use your headlights?

Using headlights from half an hour before sunset until half an hour after sunrise, and in poor visibility, is essential for ensuring safety on the road. This timing corresponds to periods when natural light diminishes, significantly reducing visibility and making it harder for drivers to see obstacles, traffic signals, or pedestrians. Additionally, using headlights during poor visibility, such as in rain, fog, or snow, helps make your vehicle more conspicuous to others, thereby reducing the risk of accidents.

Driving with headlights in these conditions not only complies with the law but also enhances overall road safety by improving visibility for both the driver and other road users. In contrast, while using headlights at all times during daylight may seem reasonable for visibility, it is not mandated by law, and there are specific situations, such as within city limits or only in severe weather conditions, where headlights are not required consistently. Thus, the specified times and conditions in the correct answer encompass the legal requirements for using headlights effectively.
