On a windy day, if a dust storm reduces visibility, what should you do?

When visibility is reduced due to conditions like a dust storm, the safest course of action is to drive slower and turn on your headlights. Slowing down is crucial because it allows you to react more effectively to any obstacles or vehicles that may suddenly appear in front of you. Reduced speed can significantly decrease the likelihood of an accident in challenging weather conditions.

Turning on your headlights is important because it enhances your visibility to other drivers. In low visibility situations, headlights help ensure that your vehicle can be seen by others on the road, which is vital for maintaining safety. Utilizing your headlights in such scenarios is a recommended practice in California as well as many other places, as it provides a clear signal to surrounding drivers of your vehicle's presence.

Driving faster to cross quickly would expose you to greater risks, as it limits your ability to respond to unforeseen hazards. Using parking lights does not provide adequate illumination for driving; they are primarily meant to signal that a vehicle is parked and can create misunderstandings about your vehicle's status on the road. Therefore, the most prudent response during a dust storm with limited visibility is to slow down and use your headlights to enhance safety for everyone on the road.
