When driving in foggy weather, it is important to use your headlights set on dim. Using high beams can actually make it harder to see because the bright light can reflect off the fog and create glare. Hazard lights are typically used when your car is stopped or disabled on the side of the road to alert other drivers, but they are not meant for improving visibility in foggy conditions. Fog lights are specifically designed to be lower to the ground and aimed towards the road to help you see better in foggy conditions, but using headlights on dim is the most appropriate choice for improving visibility in foggy weather, whether during the day or night.
