Ever think that you might be better than most others on the road? You might be right.

A recent test administered GMAC Insurance indicates that most people wouldn't pass a driving test if they had to take it again.

• Drivers 35 and older were more likely to pass

• Illinois, Georgia, Washington, D.C., Pennsylvania, New York, New Jersey, Rhode Island and Massachusetts were the least knowledgeable states overall, with average scores under 75 percent

• Fifty-five percent of the respondents didn't know how many feet before making a left or right turn to activate their turn signals

• The national average score was 77.1 percent
