As the temperatures plummet, the most important aspect of your car is that it continues to start and handles well even on icy roads. To protect against getting stranded, first check the battery, Consumer Reports says; if it’s five years old or weak already, replace it. Replace your wiper blades to ensure that they can quickly clear away the snow, mist and dirt that will kick up from the road in inclement weather. Check and top off (or change) the oil and antifreeze. And finally, consider investing in new tires — all-season radials or snow tires — if any of the tread on the current tires is getting low.
