When compared to motorists in the rest of the country, Maryland drivers are among the worst, a new study recently found.

In the 2011 GMAC Insurance National Drivers Test, Maryland motorists are ranked 49th in the country, based on their knowledge of basic driving rules and regulations. Additionally, the state had an average score of 73.3 percent, with 70 percent being the passing mark. Over 30 percent of Marylanders failed the test. The state’s most recent score is a steep fall from its 20th ranking last year.

Kansas drivers topped the list with an average score of 82.9 percent, while Washington, D.C. motorists came in dead last with 71.8.

Nationally, the study found that 1 in 5 drivers or 18 percent of Americans can’t meet the basic requirements if they took the written drivers exam today.

GMAC also found that the northeast is the region with the worst drivers, with an average scoring at 74.9 percent. The report claimed that seniors ages 60-65 were the most knowledgeable drivers.

The annual survey polled over 5,000 licensed drivers in each state ages 16-65 from 50 states and the District of Columbia. This year’s test administered 20 questions taken from state Department of Motor Vehicles exams.

Baltimore’s WBAL-TV asked Marylanders to weigh in on the state’s bad driving record, and most respondents agreed with the ranking.
