leave sidelights on
If you have to park your vehicle in foggy conditions it’s important that it can be seen by other road users. Try to find a place to park off the road. If this isn’t possible leave it facing in the same direction as the traffic. Make sure that your lights are clean and that you leave your sidelights on.
