We have a 550' uphill (8 degree slope and worse in some points), north facing driveway in winter, we thougth it would be a nightmare when we bought it but loved it and just wanted the seclusion. We got great advice from the previous owner who lived there for ten years and just needed to move to a smaller place due to age.
Recommendations: Make sure you have a four wheel drive vehicle and make sure you have snow/traction tires and in some places, you can have studded tires like in our province. Then make sure you have a reliable tractor with both a bucket to push snow and blower to move snow. Then have a smaller side by side or 4x4 to use in the most difficult situations to get up and down when you don't have time to plow or move snow off the driveway. Finally, order a mix of course sand and salt (we use about 56 or 6 yards delivered in early fall) to put on the surface only after you remove the snow, if a gravel combination with dirt driveway, better chance of keeping good traction.
We have even been able to use our Ram truck with 4 wheel drive even on snow and ice to get up and down but only if you keep your speed up and down very low and steady, no heavy braking at all and no heavy acceleration when going up. So, great all terrain or heavy tread snow tires(studs if allowed), course sand and salt mix to spread after clearing the entire driveway, you can save amounts by covering only one drive wheel side of the vehicle tracks, tractor for blowing and pushing snow with bucket (blow up hill and push downhill), are just some of the options. Good luck
