What is the correct action when visibility is less than 500 feet?

When visibility is less than 500 feet, the appropriate action is to use headlights. This ensures that you can see the road ahead clearly and that other drivers can see your vehicle, which is crucial for safety in low-visibility conditions. Headlights provide the necessary illumination to navigate safely and help prevent accidents by making your vehicle more visible to others.

Using high beams in such conditions can be counterproductive, as they can create glare and may further reduce visibility, especially in fog or rain. Activating hazard lights is generally used to indicate that your vehicle is stationary or operating in a manner that could pose a danger, but they do not provide the illumination needed for safe driving. Turning off lights to save battery can compromise safety and is not a recommended practice when driving in reduced visibility, as it prevents you from being seen by other vehicles.
