Winter driving The season poses special challenges for highway travel across much of North America.
Freezing temperatures, snow, ice and reduced daylight all affect highway travel, and require extra precautions. Remember that oil and antifreeze need to be changed periodically. In some snow areas, you may want to add heavy-duty snow tires, or carry snow chains in the trunk. Check the wiper blades, and replace if they're worn. Keep an ice scraper and snow brush in the car, and extra washer fluid.
