Bruce Siceloff on Crosstown Traffic: GMAC Insurance says it tested 5,183 drivers in all 50 states on their knowledge of driving laws, and North Carolina ranked slightly above the median at No. 20.
That's good, compared with the rest of the Southern states. All of them ranked lower, from Virginia at No. 21 to Georgia at No. 47.
Generally, most of the best were from the West (Idaho, Wisconsin and Montana were the top three). And generally, the least were from the South and the Northeast.
Test-takers stumbled most on questions about yellow lights and safe following distances. On the test with 20 questions taken from actual DMV tests across the country, the average North Carolina score was 78.2 (the passing grade is 70).
