What is a safe practice when driving in fog?

Using low beam headlights and increasing your following distance is the safest practice when driving in fog. Low beam headlights are designed to provide adequate visibility without creating glare, which can occur with high beam headlights. High beams reflect off the fog, making it difficult to see.

Additionally, increasing your following distance allows for more reaction time in case the vehicle in front of you suddenly stops or slows down due to the limited visibility caused by fog. This extra space is crucial for maintaining safety, as it helps ensure that drivers can respond appropriately to unexpected conditions.

Turning on hazard lights is not advisable while driving, as it can confuse other drivers about whether you are stopping or driving normally. Decreasing speed dramatically can be dangerous if not done smoothly, and staying in the middle of the road poses risks of drifting into lanes of opposing traffic or getting too close to other vehicles. Therefore, the combination of low beam headlights and increased following distance is the optimal approach for safe navigation through foggy conditions.
