They handle fine as long as you have good all season radials or snow tires and good technique. Good technique primarily consists of leaving lots of room everywhere around you, doing everything a lot more slowly, and thinking ahead.
I also suggest that you replace (prior to winter) your windshield wipers with booted winter wipers (regular ones will ice up) and replace your wndshield washer fluid with winter mix (summer mix will freeze in the lines). And get a good scraper and snow brush well before you need it.
