In what situation should a driver utilize their headlights during the day?

Answer: C — In adverse weather conditions, like rain or snow

A driver should utilize their headlights during the day in adverse weather conditions, such as rain or snow, to enhance visibility. When weather conditions reduce visibility, headlights help illuminate the road ahead and make the vehicle more noticeable to other drivers. This is particularly important since heavy rain or snow can create a veil that obscures both the roadway and the vehicle, increasing the risk of accidents. Using headlights in these conditions promotes safety by ensuring that other drivers can see you clearly, thereby helping to prevent collisions or misunderstandings on the road. This practice aligns with the rule that encourages drivers to take extra precautions when visibility is compromised, regardless of the time of day.
