Turning on your headlights from dusk until dawn and in low visibility conditions is essential for ensuring your safety and the safety of others on the road. Headlights enhance your visibility to other drivers and allow you to see the road better when natural light diminishes or when environmental factors reduce visibility, such as fog, rain, or snow. This rule is vital for maintaining safe driving practices, as it helps prevent accidents that could occur if other drivers cannot see your vehicle. While using headlights during the daytime might sometimes be advisable in certain conditions, the primary requirement is during lower light situations and when visibility is compromised. Additionally, while it's important to use headlights in heavy rain and when entering a tunnel, these actions are specific situations rather than the comprehensive rule that headlights should be on from dusk until dawn and in conditions of low visibility. This guideline confirms the importance of proactive safety measures while driving.
