You remember the general rules? Dipped headlights (not sidelights or running lights) on at all times (save for when you put them on main beam) and keep to the speed limits especially in towns and village between the skyline signs. Watch out for speed limit reductions for crossings, junctions, schools, watch out for fast (left) lanes becoming left turn lanes and slowing down unexpectedly on main highways (but not otorways, thank goodness!).
Now we're heading into winter, for everyone's sake, put on your winter tyres. The difference in grip will convince anyone they're worth the cost, whether you're driving rwd, fwd or 4wd. Don't forget, though, that winter tyres do NOT make you a driving god ... and that the car in front or coming the other way may not have them fitted.
