Most importantly, if you can, stay off the roads so the plow trucks can do their work.
But if you have to drive out into the snow, AAA cautions drivers to first remove all snow and ice from cars, leave plenty of following distance from the car in front of them, and never use cruise control in slippery weather.
AAA also says drivers should fill their gas tank and gather a winter vehicle emergency kit.
Items in the kit should include a flashlight with batteries and a bag of abrasive material, such as kitty litter or sand, in case you get stuck.
Also, check your car battery, which can be done for free at many auto supply shops or AAA if you are a member.
Finally, inflate your tires. Under-inflated or over-inflated tires won't grip the road properly.
