The sixth annual survey by GMAC Insurance National tested the driver knowledge of 5,202 licensed Americans.
20 questions were taken from state Department of Motor Vehicles (DMV) exams. Additional questions explored distracting habits such as texting while driving.
Findings indicate that a large number of licensed Americans still lack knowledge of basic rules of the road.
85 percent could not identify the correct action to take when approaching a steady yellow traffic light, and many remained confused by safe following distances.
The Northeast had the lowest average test scores (74.9 percent) and had the highest failure rate (25.1 percent). The Midwest region had the highest average test scores (77.5 percent) and the lowest failure rates (11.9 percent).
Results also indicate that the older the driver, the higher the score. Males over 45 earned the highest average test score.
