In wet weather when it becomes hard for you to see, you should:

• A. Flash your headlights to warn other drivers.
• B. Turn on your headlights, slow down, and double your following distance behind the vehicle in front.
  Explanation:

  "Your stopping distances will increase in the wet, and if visibility is impaired it may take you longer to react to an emergency situation. Other vehicles will not be able to see you as easily, therefore headlights are important."
