The best car insurance companies have a few things in common: They have straightforward shopping experiences, take good care of policyholders after a crash and treat their customers with respect and courtesy. That means only insurers with high customer satisfaction scores and relatively few complaints to insurance commissioners make it to the top of our list of the best auto insurance companies.
Insurance companies cannot raise premiums instantaneously to reflect incurred losses. That's because rate changes—in most states—must be submitted and reviewed by the state's department of insurance before they can go into effect. As a result, rate changes that are brought on by a loss-causing event—such as a hurricane—may take some time to go into effect.
The auto insurance rates displayed in our articles are based on the 2019 results of The Zebra’s comprehensive car insurance pricing analysis. In our analysis of all US zip codes — including Washington D.C. — the sample user profile consisted of a 30-year-old single male driving a 2013 Honda Accord. To generate pricing specific to particular rating factors, we adjusted the driving profile based on pricing factors commonly used by car insurance companies.
You should also look into how the company handles the claims process, as the single biggest indicator of home insurance customer satisfaction is the company’s damage estimates. If they have a reputation for not covering the agreed-upon replacement costs of property or dropping customers from their policy for filing a single claim, you should probably avoid that company.
Basic coverage — which is required by law — offers you protection for personal injuries and damages to the vehicle, but it won’t cover extras like your belongings inside. If you live in your RV full-time, it might also be a good idea to invest in additional protection that covers your housing expenses or RV replacement costs. Before shopping around, draw up a list of necessary coverage options and make sure they’re offered by your prospective provider.
An additional possible contributor to future rate hikes is the increased frequency in car crashes attributed to distracted driving—caused in large part by more people using their phones while driving. The National Highway Traffic Safety Administration (NHTSA) reports that 2.443 million people were injured in distracted driving crashes in 2015, which is an increase from 2.217 million people in 2011. Insurers respond by raising rates to make up for the increase in insurance claims they have to pay out.
Idaho is pretty sparsely populated and mainly rural which leads to lower car insurance rates. According to World Atlas, Idaho has the seventh least population density in the country. There are roughly 20 people for every square mile. Wide-open spaces with few people mean fewer cars out on the road and fewer accidents, everything an insurance company loves.
