Be careful next time you start arguing about which state has the worst drivers—unless you are debating someone from New York. GMAC Insurance has released a ranking of states plus the District of Columbia that judges driving knowledge based on a national online driver’s test. New Jersey ranked 50 of 51, just behind D.C. and slightly ahead of New York. This is the fourth year out of five that New Jersey and New York have ranked at the bottom. In general, the Northeast had the lowest average scores and the highest failure rate, while the Midwest ranked best. The test, which was a sampling of 5,202 licensed motorists weighted by location, gender, age and ethnicity, consists of 20 multiple-choice questions derived from Department of Motor Vehicle tests. To see how you score, take the test yourself.
