CHARLESTON, W.Va. -- About 39,000 motorists in West Virginia, Kentucky, Ohio and Western Pennsylvania are expected to call AAA East Central for help while traveling during the Christmas and New Year's holidays. AAA East Central projects that it will replace more than 6,500 dead car batteries, change nearly 6,000 flat tires, retrieve nearly 4,800 sets of keys locked inside vehicles and extricate 2,000 vehicles stuck in snow or mud. Some vehicle problems can't be fixed at the roadside, though. AAA expects that nearly 16,000 motorists will have to have their vehicles towed. Steve Popovich of AAA's Automotive Services said many breakdowns can be avoided with a little preventive maintenance, including checking antifreeze level, tire pressure, battery, belts and hoses before starting a trip.
