Which action is typically NOT recommended when driving in fog?

Turning off your headlights is not recommended when driving in fog because headlights are crucial for visibility in low-visibility conditions. In fog, headlights can help illuminate the road and any potential hazards. It is essential to use low beam headlights rather than high beams, as high beams can cause light to reflect off the fog, creating a glare that obscures vision even more.

In contrast, reducing speed is vital in foggy conditions to allow for better reaction time if obstacles appear suddenly. Using front fog lights, if the vehicle is equipped with them, is recommended as they are designed to illuminate the road immediately in front of the vehicle without reflecting back off the fog. Additionally, increasing the following distance is important because it provides more time to respond to any changes in traffic conditions, which can be unpredictable in fog.
