Where Do the Best, Worst Drivers Live?

CARS.COM — The average American motorist is involved in an auto collision once every decade, according to a study by insurance company Allstate. Depending on where you live, though, that frequency can be a lot less — or a whole lot more.

A border town at the southernmost tip of Texas took the safest-city title for the first time in the 2016 edition of Allstate’s annual America’s Best Drivers Report. Motorists in Brownsville, Texas, on average are involved in a collision once every 14.6 years and are 31.4 percent less likely to crash relative to the national average. The agency’s study measures vehicle collision frequency in the nation’s 200 largest cities to determine where the safest drivers reside.

Brownsville displaces last year’s safest city, Kansas City, Kan., bumped down to No. 2 this year with a crash every 13.6 years and a 26.3-percent reduced likelihood of an accident. Boston, on the other hand, has a collision frequency of one every 3.7 years and a 167.6 percent greater likelihood of a crash (nearly 10 percent worse than in 2015).

Among the nation’s three largest cities, Chicago lays claim to the best drivers, who go an average of 8.5 years between accidents and have only an 18.2 percent heightened likelihood of being in one. New York is close behind the Windy City with 8.3 years and 20.3 percent greater likelihood. The nation’s capital of car culture, meanwhile, also happens to be home to some of the worst drivers, according to Allstate: Los Angeles ranks in the top 10 most dangerous driving cities with an average of 6.3 years between crashes and a 58.8 percent greater chance.
