What is the primary purpose of using headlights in adverse weather conditions?

Using headlights in adverse weather conditions is primarily meant to improve visibility for both the driver and other road users. When driving in conditions such as rain, fog, or heavy snow, visibility is often significantly reduced. Headlights provide essential illumination that helps the driver see the road ahead, as well as identify obstacles, road signs, and other vehicles.

Additionally, having your headlights on during these conditions makes your vehicle more visible to other drivers, which is crucial for preventing accidents. It allows other road users to better gauge your distance, speed, and intentions. This dual benefit of enhancing visibility is why using headlights in adverse weather is a critical safety measure, reinforcing the importance of visibility in ensuring safe driving practices.
