How do I use my car lights correctly in snowy weather?
When driving in snowy conditions, check before setting off that all lights are clear of snow and ice. In heavy snowfall, use fog lights instead of high beams and remember to turn off your rear fog lights when visibility improves so that you do not dazzle or distract others.
In heavy snowfall, high beams can impair visibility, so switch to low beams (and use front fog lights if necessary).
