If the rules of the road are a mystery to you, you're far from alone. According to CBS News Money Watch, a new survey of 500 drivers found that 44 percent couldn't get a passing score on a written driving test.
Drawing questions from state drivers' license practice tests, CarInsurance.com reports that only 56 percent of respondents could get the 80 percent score required to pass.
Women did better than men, getting an average score of 78 percent, versus 71 percent for males. Older drivers also outscored their younger counterparts. People over 40 got 79 percent right, while those under 40 got an average score of just 67 percent.
