You'll want to have a snow shovel before the snow falls. Get an ergonomic one, with an oddly bent handle. Much easier to use than a straight-handled shovel. If your neighborhood has sidewalks, it's your responsibility to clear snow from the sidewalks that border your property. If there's a big snowfall, like 8" or more, a snowblower is a godsend. Might be worth it to get a used one for $100 on craigslist or FB marketplace.

You will also want a snow brush/ice scraper for each car. Get a sturdy one. If it's freezing outside, turn you car's windshield defroster on, with the fan on, as soon as you start the car. If you leave it off until the car is warmed up, and then turn the hot air onto the windshield, you risk cracking the windshield.

If there's snow on your car, use your snow brush to clear the snow off of all the windows, and the headlights, taillights, third brake light, and license plates. If there's a lot of snow, brush or scoop it off of the hood, roof, trunk lid (otherwise, it will blow off and obscure your or someone else's visibility).

If there's freezing with snow or sleet in the forecast, lift the windshield wipers up and let them stand proud. This prevents them getting frozen to the windshield. If they do get frozen to the windshield, free them before attempting to turn them on. It's possible to break the plastic clips that hold the wiper transmission together, and then you have no wipers until that's fixed.

Keep windshield washer fluid in the trunk. You'll go through that in a sloppy winter in no time, even if it's not actively snowing, because other cars will kick up wet road dirt that just smears when you use the wipers dry.

When the temperature falls in the autumn, and then again in the winter, your tire pressure will go down. Check your tire pressure to make sure everything is properly inflated for proper traction and more even tire wear.

When driving, be prepared to use your parking brake to assist with stopping in an emergency. My Ford Fusion is awful stopping in the snow, so I keep a finger on the electric parking brake at all times. If it starts sliding, adding the parking brake helps immensely.
