(Washington Examiner) — While Washington may lead the United States as the capital of the free world, its motorists lead the nation as the worst drivers. Allstate Insurance Co., which examined claims data from January 2008 to December 2009, found that the average D.C. driver goes 4.8 years between accidents. That’s twice as frequent as the national average of 10 years between accidents and almost three times as frequent as America’s safest city for motorists, Fort Collins, Colo. The results of the study shouldn’t surprise local drivers. Washington has ranked last among the hundreds of cities tested in the Allstate study three consecutive years. Drivers in the region are 107.3 percent more likely to get into an accident than the national average.
