In a nutshell...

  • It’s always a good idea to compare at three different quotes before making a final decision
  • California law requires all drivers to have insurance coverage when operating a vehicle
  • Look for a company that has a strong financial rating

When comparing auto insurance, the California Department of Insurance (CDI) has a list of top car insurance companies in the state, according to market share.

However, just because a company has a large portion of the market does not mean that the company is financially stable or provides quality service to its customers.

A.M. Best is an independent rating company that tracks the financial health of an insurance company rather than its market share.

After analyzing information from both A.M. Best and the CDI’s list of insurance companies with great market shares, inferences can be drawn between the two criteria.

Which car insurance is the best for Californians?

While there are several car insurance companies that are popular among California residents, one car insurance cannot meet everyone’s individual needs and criteria.

The car insurance companies that are top rated are so because they meet a substantial portion of customers’ needs and are financially stable.

However, when looking for car insurance, you shouldn’t just rely on which company is top rated.

The information on the financial stability of the company is important and it should be used as a starting point when researching car insurance rates.

Looking at the reviews of other customers is important when finding the best car insurance for you and your family. Some value great customer service over low rates, while others are happy with low rates and mediocre customer service.

Where can you research car insurance companies and their rates?

There are several ways to research car insurance company rates. First, you can do quite a bit of the legwork online.

With companies utilizing the ease of online usage such as Progressive, customers can compare and contrast different car insurance quotes.

For those who enjoy a more one-on-one approach, customer service representatives are available either by phone or at a local insurance agent.

Either of these choices will help you get the answers you are looking for when it comes to finding the best insurance rate for you and your family.
