Must admit seems to be stupid to have kept going. I take it he stopped anyway to have a go at you?.
Personally if Possible, although by the sound of it you'd already passed where you could pull in before you saw him, I would stop going uphill and give way to coming down hill in snow regardless of what the highway code says. Thats based on the fact that it's harder to get started agian, and not that a vehicle coming down hill on snow may skid and loose control hitting you coming up. I've seen it happen. Although i've also seen a bus unable to get up a hill, and slew across a road and get wedged against a building unable to move untill the snow melted. Can you remember that really bad snow we had that bought all the power cables and telephone cables down, and cut off the water for a week.
