If you are driving on a very windy day and a dust storm reduces your visibility, what should you do?

Answer: B — Drive slower and turn on your headlights

Driving in windy conditions and dust storms can significantly impair visibility and increase the risk of accidents. The correct course of action is to drive slower and turn on your headlights. This approach helps to enhance your visibility to other drivers while also allowing you to maintain better control of your vehicle as you navigate through challenging conditions. Slowing down provides you with increased reaction time in case obstacles appear suddenly, and using headlights makes it easier for other motorists to see you, reducing the chances of a collision. Maintaining your speed in such conditions could lead to losing control of your vehicle, while speeding up would only increase the risk of accidents as your visibility decreases. Pulling over to the side of the road could be a good option in some scenarios, but it must be done safely and with attention to avoid being hit by another vehicle. However, riding it out by slowing down and using headlights is the most effective and safest approach overall when visibility is compromised during a dust storm.
