Which of the following can improve vehicle visibility in poor weather conditions?

Using headlights and fog lights is indeed the best choice for improving vehicle visibility in poor weather conditions. When visibility is reduced due to rain, fog, or snow, using headlights enhances not only your ability to see the road but also allows other drivers to see you more clearly. Fog lights are specifically designed to cut through dense fog, rain, or snow, directing light closer to the ground to illuminate the road surface without reflecting off the precipitation.

While options like keeping windows tinted and driving at a higher speed can adversely affect visibility and safety, maintaining a distance from other vehicles primarily targets safe driving practices rather than directly improving visibility. In contrast, effective use of headlights and fog lights significantly contributes to safer driving in adverse weather, making them essential tools for improving overall visibility on the road.
