When driving in fog, what should be used to help you see?

Answer: B — Low beam headlights

In foggy conditions, visibility is significantly reduced. High beam headlights reflect off the fog and create glare, making it difficult to see. Flashlights are not ideal for driving as they only provide a narrow beam of light and need to be held by someone. No lights should not be used as it can make your vehicle invisible to others. Low beam headlights, on the other hand, provide a focused beam of light that does not reflect off the fog, allowing you to see better in these conditions. Therefore, low beam headlights should be used when driving in fog to help maintain visibility and minimize glare.
