When driving in fog, what type of headlights should you use?

Answer: B — Low beam headlights

When driving in fog, using low beam headlights is essential for visibility and safety. Low beam headlights are designed to illuminate the road directly in front of the vehicle without causing excessive glare that can reflect off fog, rain, or snow. This lower light setting helps provide clear visibility to the driver while minimizing the chance of blinding other drivers or creating a stark contrast that reduces visibility in foggy conditions. In contrast, high beam headlights can create a glare that reflects off the fog, making it harder to see the road ahead. Fog lights, while designed to provide additional illumination close to the ground in foggy conditions, are generally used in conjunction with low beams rather than as a standalone. Daytime running lights do not provide sufficient illumination for poor weather conditions, as they are primarily intended to increase the visibility of the vehicle during daylight hours. Therefore, low beam headlights are the appropriate choice when navigating through fog.
