In a nutshell...
  • State Farm has the highest percentage of market share in the USA
  • Even the largest car insurance companies sometimes do not have all the options you need as a driver
  • Over 100+ car insurance companies are licensed in most states, so there is no lack of choice

When drivers search for car insurance rates one of the biggest factors to convince a driver to choose one car insurance company over another is a car insurance company’s reputation.

Intangible factors like hours of operation, online account management options and the claims handling process can always sway people to pay a little more.

You need to spend the time comparing car insurance companies based on the type of coverage, policy limits and premiums offered.

You also may want to make note that market share statistics are usually released on a national level and are much harder to find broken down by state.

While Geico or State Farm have significant portions of the car insurance market nationwide many local or regional car insurance providers, have outstanding market share within their geographic footprint.
