What should you do if visibility is severely reduced while driving?

Answer: B — Pull over and wait for conditions to improve

When driving conditions become severely reduced in visibility, the safest and most prudent action is to pull over and wait for conditions to improve. This approach minimizes the risk of accidents caused by not being able to see clearly, which can lead to dangerous situations on the road. By stopping in a safe location, such as a parking lot or a designated pull-off area, you allow yourself time to assess the situation without the added dangers of navigating through poor visibility. Driving faster to escape the situation can actually increase the risk of an accident, as you may not be able to react in time to obstacles or other vehicles. Relying on high-beam headlights during poor visibility—such as in heavy rain or fog—can also create issues, as these lights can reflect off precipitation or fog, further impairing visibility. Lastly, following other vehicles closely under such conditions is dangerous; it can lead to a rear-end collision if the vehicle in front of you slows down or stops suddenly. By choosing to wait until visibility improves, you significantly enhance your safety and that of others on the road.
