If your visibility is reduced to 500 feet or less, what must you do?

When visibility is reduced to 500 feet or less, turning on your headlights is essential for enhancing your ability to see the road ahead and for making your vehicle more visible to others. This is particularly important in conditions such as fog, heavy rain, or nighttime driving, where limited visibility can lead to accidents. Headlights help illuminate the surrounding area, allowing the driver to identify potential hazards and obstacles more clearly. Additionally, they signal to other drivers that you are present, helping to prevent collisions.

While activating hazard lights can alert other drivers to your presence, it does not improve your visibility or help you see the road as headlights do. Slowing down is also a prudent measure to take when visibility is poor, but it should be accompanied by the proper use of headlights to ensure you can see well enough to drive safely. Pulling over to a complete stop may be necessary in some extreme situations, but it is generally not required if you can manage your speed and visibility effectively with your headlights on.
