You should take a look at your auto insurance policy every year to find out how much you're paying in premiums and how much coverage you're getting in return. The cost of the same policy can vary widely between companies based on factors like how much the company spends on advertising, commissions paid to the agent and the risk levels of the company's pool of insured drivers.
To start comparing quotes, try logging on to an auto insurance aggregator Web site like NetQuote.com, Insure.com or InsWeb.com, where visitors submit information about their car and driving history in exchange for an array of quotes from different insurance companies. Typically, many of the quotes come via follow-up e-mails and phone calls from insurance agents. You can also try searching Web sites for companies like Progressive and Geico, which sell insurance directly to consumers and provide quotes immediately.
Before you submit any sensitive information through a Web site, look for a security policy to ensure that any communications are reasonably protected from third parties, and set your Web browser to notify you when you leave a secure connection.
