If you are driving in fog, what lights should you use?

When driving in fog, using low beam headlights is the recommended practice because they are designed to illuminate the road immediately in front of your vehicle without causing glare. High beam headlights can reflect off the fog and create a blinding effect, making visibility worse instead of better. Parking lights are not sufficient for driving as they do not provide adequate illumination for navigating the road safely. Fog lights are specifically designed to cut through thick fog but should be used in conjunction with low beams rather than exclusively. The combination of low beams and fog lights allows for better visibility and safer driving conditions in foggy weather.
