No. 5: Nevada
Nevada ranks as the fifth-most expensive state in the country, with a total annual cost of $3,886, according to Bankrate's analysis. The culprits? High insurance premiums and taxes.
Insurance is high in the Silver State in part because its drivers seem to have particular trouble staying between the lines. There were 84 injury-related collisions reported for every 100 million miles traveled, according to Nevada's 2010 accident statistics. That's well above the national average of 52 crashes per 100 million miles traveled.
The more crashes, the more insurance companies want to charge to insure drivers in the state, says Rajat Jain, assistant chief of property and casualty with the Nevada Division of Insurance. At an average of $970 per year, insurance premiums in Nevada are the seventh-highest in the U.S.
Besides high insurance costs, Nevada also charges a 6.85 percent state sales tax -- the eighth-highest in the country. And many of its counties pile on even more sales taxes. In Clark County, which includes Las Vegas, car owners pay 8.1 percent sales taxes, or $2,430 in sales taxes on a $30,000 vehicle.
