When you're getting cut off in traffic or stuck behind adawdler, you may be convinced you're surrounded with the country'sworst drivers. But are you?

CarInsuranceComparison.com,an auto insurance comparison website, recently compiled data fromthe National Highway Traffic Safety Administration, the NationalMotorists Association and Mothers Against Drunk Drivers to rank all50 states and the District of Columbia by those with the worstdrivers.

There are five categories for each score, including:

• Fatalities rate per 100 million vehicle miles traveled
• Failure to obey (traffic signals, seat belts)
• Drunk driving
• Tickets
• Careless driving

CarInsuranceComparison.com translated this information into asingle score. The higher the score, the worse the state's drivers.For example, the state with the most careless driving, Florida, gota 51 on the scale (District of Columbia is included in therankings). The higher the score in each category, the worse thedrivers, and the higher your state'scar insurance rates could be.

Although it's not scientific, the study generates lots ofcontroversy, said Jeffrey Crews, vice president ofCarInsuranceComparison.com. “There are several reasons for that,”he said. “One, it's the holiday season. People are traveling, andthat comes into play. Plus, this is something that always comes up.Somebody is always saying, 'This is a horrible state to drive in.'And they can take this and say 'I told you so.'”

Read on to see which states made the Top 10.
