Which driving technique is most effective for maintaining visibility in low-visibility conditions?

Answer: C — Utilizing fog lights and low-beam headlights

Utilizing fog lights and low-beam headlights is the most effective technique for maintaining visibility in low-visibility conditions, such as fog, heavy rain, or snowfall. Fog lights are designed to project a wide, low beam of light that illuminates the road immediately in front of the vehicle without causing significant glare that can reflect off fog or precipitation. This allows drivers to see the road and any potential obstacles more clearly while minimizing the risk of blinding other drivers. Low-beam headlights complement fog lights by providing additional lighting while also reducing glare. In contrast, high-beam headlights can reflect off fog or rain droplets, creating a white wall of light that can hinder visibility rather than enhance it. Using turn signals continuously or exceeding the speed limit doesn't improve visibility and could potentially lead to unsafe driving conditions. Therefore, the combination of fog lights and low-beam headlights is the most appropriate choice for ensuring safe driving in low visibility.
