When is it necessary to use your headlights?

Using headlights is necessary in low visibility conditions or during nighttime to enhance safety on the road. Headlights improve your ability to see other vehicles and obstacles, and they make it easier for others to see you. In conditions with reduced visibility, such as fog, rain, or snow, headlights can help illuminate the road in front of you, allowing for better reaction times and overall safer driving.

Moreover, using headlights during nighttime is a standard practice as it is typically dark outside, making them essential for safe driving. It's important to note that in some areas, there may be specific laws regarding the use of headlights during certain weather conditions, contributing to the necessity of their use in adverse situations as well.
