Why is driving in fog dangerous during winter?

During the dense fog season (November to January), visibility can drop to a few meters on plains and motorways. Drivers lose lane reference and cannot see slow vehicles ahead, which causes chain collisions. Reducing speed and using low-beam headlights keeps you safe.

What should I check before a fog trip?

Check headlights, tail lights, brake lights, fog lamps, wipers, tire tread and pressure, keep fuel above half, charge your phone, and make sure windows and mirrors are clean.

Should I use high beam headlights in fog?

No. High beam reflects off the fog droplets and makes visibility worse. Use low-beam headlights in fog, and fog lamps if your vehicle has them.

What is a safe following distance in dense fog?

Keep at least a 5-second gap between your vehicle and the one ahead, and drive slow enough that you can stop within the distance you can clearly see.

What should be in a fog emergency kit?

A warm blanket, torch with spare batteries, reflective warning triangle, first-aid kit, drinking water, a dry snack, and a charged power bank for your phone.

Reduced speed well below the limit — ready to stop within the distance I can see.

Using low-beam headlights only — never high beam in fog.

Keeping at least a 5-second gap from the vehicle ahead.

Following road edge lines to stay in lane; no unnecessary lane changes.

No overtaking unless the road ahead is fully clear and visible.
