2) Many factors can affect your car insurance rate.
Auto insurance companies use many different criteria when evaluating an insurance application during a process called underwriting. Each car insurance company has many guidelines regarding which groups of drivers they want to accept and how much they will charge those groups they consider a greater risk. The guidelines are different for each company, meaning that two companies comparing the same driver can arrive at vastly different conclusions.
During the underwriting process, car insurance applicants are placed in a group based on how much money and how many claims the insurance company believes it may have to pay. Underwriting is done automatically by software behind the scenes.
At this time, the insurance company will look at motor vehicle records to see how many accidents or tickets a driver has received. Many insurance companies also use an insurance history report to see if the driver has made any car insurance claims, and how much money was paid. Although accidents and violations can only affect the rates you receive for three years, many companies will look back five or more years when deciding if they want to offer you insurance.
In addition, many auto insurance companies look at the credit history of the applicant. Typically,drivers with bad or no credit history pay more. But that means you can save money (quite a bit) by shopping around as your credit improves.
