Fog Driving Safety Guide
Winter fog makes driving dangerous, especially on Pakistan motorways. Use this interactive checklist before you drive, check your following distance with the calculator, and read the motorway-specific safety tips. Free to use, no signup needed.
In fog you should keep at least a 4-second gap — double the normal 2-second rule. Enter your speed to see what that gap looks like in metres.
Stopping distance is a rough estimate on a dry road (reaction time 1.5 seconds plus braking). Wet or slippery roads need even more distance.
- Helpline 130: save the National Highways and Motorway Police helpline number 130 in your phone before you travel.
- Check before you leave: motorways are frequently closed during heavy winter fog. Confirm the latest status before starting a long journey.
- Follow patrol convoys: if motorway police lead a slow convoy through fog, join it — do not try to pass it.
- Exit instead of stopping: in dense fog, leave the motorway at the nearest interchange and wait it out. Never stop on the shoulder.
- Watch the studs: reflective road studs (cat eyes) mark the lane edges and are often the only guidance visible in thick fog.
- Keep low beam on: even in daytime fog, low-beam headlights make your car visible to others.
Should I use high beam headlights in fog?
No. Use low beam headlights. High beam light reflects off the fog and reduces how far you can see.
How much following distance should I keep in fog?
Keep at least a 4-second gap between you and the vehicle ahead, which is double the normal 2-second rule. The calculator on this page converts that gap to metres for your speed.
What is the motorway helpline number in Pakistan?
130. It connects you to the National Highways and Motorway Police for help on motorways and national highways.
