Question: 1 / 400

In foggy conditions, what lighting should you use?

High-beam headlights

Low-beam headlights

When driving in foggy conditions, it is important to reduce your lights' contrast with the fog. High-beam headlights tend to reflect off the fog, making it harder to see and potentially blinding other drivers. Fog lights, while specifically designed for these conditions, may not provide enough visibility by themselves. Using just the fog lights may also create a lack of contrast and distance perspective. Using no lights at all can be extremely dangerous, as other drivers may not see you in time to avoid a collision. Therefore, the best option is to use low-beam headlights, as they create a beam that is lower to the ground and less likely to reflect off the fog, providing the best visibility and safety in this situation.
