When must headlights be turned on according to Georgia law?

Answer: D — All of the above

In Georgia, the law requires headlights to be turned on in several specific circumstances to enhance safety on the road. Headlights must be used at night, which is the most intuitive scenario as it is primarily dark and visibility is low. They must also be turned on during rain or fog, as these weather conditions significantly impair visibility and can make it difficult for other drivers to see you. Additionally, headlights are required whenever windshield wipers are in use. This rule is in place because if the windshield wipers are needed due to precipitation, it's likely that visibility is compromised, and having headlights on ensures that a vehicle is more visible to others around it. The correct answer, "All of the above," encompasses all these scenarios, confirming that headlights must be used not just during night-time driving but also in adverse weather conditions and whenever the windshield wipers are operational. This comprehensive requirement enhances safety for all drivers on the road.
