Fog is caused by tiny droplets of water hanging in the air, and is defined when the visibility is below 200 metres for motorists.
Motorists are advised to turn on their fog lights and your dipped beams, and slow down gradually to match the conditions around you.
If you are approaching a junction make sure you slow down so that you can observe the traffic coming in each direction, and if you're still unsure, you can roll down your window as this can give you an idea if traffic is coming from different directions.
Check your mirrors if you are about to slow down and stop as the cars behind you might not be aware that you are about to stop.
