What do you do when you approach a yellow light? What’s considered a safe following distance when driving on a highway? What’s the speed limit in a school zone? Residents of Kansas got more questions like these correct than any other state. Kansas ranked first on the GMAC Insurance National Driver’s Test survey. Kansas took the number one spot after placing fourth last year.

It’s the sixth year for the survey. GMAC questioned more than 5,000 drivers from all 50 states and the District of Columbia in order to figure out which state was the most educated in the rules of the road. The drivers were asked a series of 20 questions from state DMV exams. But despite the smarts shown by Kansas residents, GMAC says Americans’ knowledge of road rules is declining. The national average test score dropped from 76.6 percent in 2009 to 76.2 percent in 2010. Almost nine out of ten drivers questioned didn’t know what to do when approaching a yellow light or what is considered a safe following distance.

Kansas drivers scored an average of 82.3 percent with drivers in Oregon, South Dakota and Minnesota not far behind. New Yorkers scored the worst, with an average score of 70 percent. Also at the bottom of the results were New Jersey, the District of Columbia and California.
