Consumer Affairs lists the top 10 auto insurance companies in the industry based upon many individual factors and includes numerous reviews for each one based upon customer experiences. These are the top 10 companies: 
- Progressive Insurance
- Esurance (owned by Allstate)
- State Farm
- Liberty Mutual
- AAA Auto Insurance
Consumer Reports, not to be confused with Consumer Affairs, names three 'top tier' auto insurance companies, and they are: USAA, Amica and New Jersey Manufacturers Insurance Company. Insurance companies that found themselves in the middle of the pack who had been high up on the list for Consumer Affairs include State Farm and Geico. It's also interesting to note that two companies that are considered low on the totem pole are Hanover Insurance and Farmer's Insurance. 
State Farm is actually the largest auto insurance company in the country, and Allstate, whose slogan 'You're in good hand' has been a widely popular company with consumers in the last couple decades. Geico was responsible for the inundation of ads with auto insurance companies claiming they can save customers money. AARP/Hartford and LIberty Mutual are two of the oldest insurance companies in the country. While known for providing roadside assistance, AAA is notably on the list from Consumer Affairs mentioned earlier.  Which auto insurance company a person selects will be up to his or her individual expectations and needs, but knowing which companies are ranked the highest helps make the choice a little easier.
