(MoneyWatch) It seems like Hurricane Katrina and the BP (BP) oil spill should be enough troubles for one state. But if you live in Louisiana, you also pay the highest auto insurance rates in the country.

According to a just-released study by the website, the $2,536 average cost to insure a car in Louisiana is nearly three times the $889 average in Maine, the lowest-cost state.

Factors that push up rates include a large number of uninsured drivers, state insurance laws, how many insurers compete in the state and whether recent natural disasters have pushed up claims. "Many of these problems are outside the control of drivers," says Amy Danise, editorial director of "But even if you live in an expensive state, you can hold down your insurance costs by keeping your driving record as clean as possible and selecting a car that is cheap to insure."

After Louisiana, Oklahoma ($2,047) and Michigan ($2,013) are the next most expensive states. High levels of insurance awards to accident victims are major factors in Louisiana and Michigan, according to In Oklahoma, in addition to many uninsured drivers, recent claims for tornado damage have pushed up rates.

Least expensive states

In Maine (average cost $889), relatively light traffic, a low crime rate and competitive rates among insurance companies contribute to low costs. Similar factors, plus a low rate of uninsured drivers keep costs down in second-least expensive Iowa ($985). Wisconsin ($987) also has a low crime rate and competition among companies and has a relatively low level of auto-related lawsuits.
