What time of day is fog the worst?

Why are high beams often a bad idea in fog?

High beams will shine directly into the fog or precipitation, which will reflect the bright light back to you. During snowstorms, snowflakes and ice crystals will reflect even more light back to you. The dangerous result is a wall of glare, which will make it even more difficult for you to see the road.

At what temperature does fog occur?

Fog forms when the difference between air temperature and dew point is less than 2.5 °C (4.5 °F). Fog begins to form when water vapor condenses into tiny liquid water droplets that are suspended in the air.

When driving in foggy weather if the fog is so thick?

If the fog becomes so thick that you can barely see, pull safely and completely off the road. Do not continue driving until the fog lifts and visibility improves.

How thick can fog get?

Why Low beams are more useful in fog than high beams?

Any time your visibility is less than 150 metres because of heavy rain, for example, you'll want to use your low beams headlights.
