Summertime is travel time. Even with gasoline prices at an all-time high, Americans can't resist the lure of sunny skies and the open road. According to a survey by AAA­, 31.7 million Americans planned to travel by car over Memorial Day weekend 2008, despite gas prices that are an average of $.60 more per gallon over the previous year [source: The Los Angeles Times].

Before hitting the road this summer, you can take several simple precautions to keep your family safe and save money at the pump. Extreme heat and long drives can be tough on cars. Cracked hoses, leaky radiators, underinflated tires and dirty filters can significantly lower your fuel efficiency, or worse, lead to a total breakdown.­
