What should drivers do if visibility is significantly reduced?

Using headlights when visibility is significantly reduced is essential for several reasons. Headlights enhance your ability to see the road, traffic signs, and other vehicles, making it safer to navigate in low visibility conditions, such as fog, rain, or during nighttime. They also make your vehicle more visible to other drivers, which can help prevent accidents.

While making choices like turning on hazard lights or pulling over may seem reasonable, these actions are not the most effective way to address reduced visibility while moving. Turning on hazard lights is intended for different scenarios, such as indicating that your vehicle is stopped or experiencing trouble, which might confuse other drivers in a scenario of poor visibility. Simply pulling over could be unsafe unless done in a designated area, as it might disrupt traffic for others. Driving faster in low visibility can significantly increase the risk of a collision, as it reduces the amount of time and distance you have to react to unexpected hazards. Therefore, using headlights is the best and safest option for maintaining visibility and ensuring safe driving during challenging conditions.
