In situations where visibility is significantly reduced, such as during a dust storm, it is essential to enhance your visibility to other drivers without creating additional glare that can further impair vision. Turning on your headlights is crucial because it allows other drivers to see your vehicle amidst poor visibility conditions. Headlights help illuminate the road directly in front of you, which can aid in navigation through the reduced visibility caused by dust or debris.

Utilizing your hazard lights is generally more appropriate when your vehicle is stationary or when you want to alert others to a hazard on the road. High beams are not suitable for situations where visibility is impaired due to dust or when other vehicles are present, as they can create glare and make it harder for surrounding drivers to see. Fog lights, while helpful in certain low-visibility conditions, are not as effective as standard headlights in this context. Thus, activating your headlights is the most effective and safe choice when navigating through a dust storm.
