Buy a couple bags of tube sand from the auto store and put them in your trunk and closest to the right side. That will help with some traction. Like you discovered, don't accelerate or brake during turns. Slow down before your turn and wait until after the turn to accelerate. Try a higher gear at slow speeds so less torque is applied to the tires. Anticipate what the other drivers will do and keep some distance. You have anti-lock brakes. When you use the brakes on ice and snow you will probably notice the pulsing...don't take your foot off the brake. Get a set of tire cables. You may be able to find some used ones for your tire size off craigslist or something. Practice putting them on and then carry them in your car. If there is enough snow on the road put them on the rear wheels. They will make a huge difference. Carry a good windshield scraper and brush. Keep one in the car and one in the house. Properly inflate your tires. Go practice in an empty parking lot after a snow storm.
