Insurance companies look at more than just the local conditions that can cause accidents when they're determining your insurance rates. One consideration, for example, is your state's policy about medical benefits. For example, Michigan guarantees unlimited personal injury protection and also requires insurers to pay victims up to three years of lost wages. Consequently, the state's rates are among the highest in the U.S. [source: MSN.com].
The legal climate in your state can affect rates, too. In Louisiana, judges are usually the ones who determine damages for accidents; a jury gets involved only if the amount of the claim is more than $50,000. Since elected judges tend to give higher awards to those injured, the insurance companies shell out more and pass on the cost to customers [source: MSN.com]. Some insurers even vary rates according to how many lawyers per capita there are in your area. More lawyers, more lawsuits.
Some areas, particularly those with high unemployment, have a larger number of uninsured drivers on the road. If one of them crashes into you, your insurance company has to pay. The result: higher premiums for those who do carry insurance.
Competition among insurance companies, on the other hand, can lower your rates. In a state with fewer accidents, like Vermont, more companies vie for your business, creating a buyer's market.
Where you keep your car matters, as well. If you live in a city, you may get a break on your insurance rate if you park your car in a secure garage. Another factor is how far you live from your job or school. A shorter commute can often translate into a lower rate.
All things considered, it's clear that your zip code can have a big influence on your auto insurance rate. But is that fair? Should all drivers in an area be penalized for a high crime rate or congested roads? Some folks have claimed that determining rates that way amounts to racial or economic profiling, and is a form of discrimination. Back in 1988, California voters passed Proposition 103 to keep insurers from penalizing customers for where they live. The law requires companies to set rates based primarily on a person's driving record, driving experience and annual mileage [source: Auto Insurance Tips].
But those who live in most other states still have to contend with premiums that vary by location. And don't think if you move to a higher rate area that you can avoid the boost by not informing your insurance company. The company may refuse to pay a claim if you haven't updated your address.
If John Lambert were alive today, he might be pleased to know that drivers in his home state, Ohio, enjoy some of the lowest insurance rates in the country for their horseless carriages [source: MSN.com]. If you're not so lucky, though, there's only one sure way to avoid paying the rate for your particular area: Sell your car and put on your walking shoes.
