If you live in an area with unusual state regulations or heightened risk of weather-related claims, shopping car insurance options will be vital. Not every car insurance company offers policies in every state, which can make pricing less competitive. If you live in storm-prone states like Louisiana or Florida, you might find it harder to get a competitive rate.
Do you live in your RV full-time, or does it sit in storage for most of the year? Do you have any permanent attachments like a satellite dish? Every company offers basic RV coverage, but the right provider for you also offers the set of add-ons that speaks to your main concerns, whether it’s full-time residency insurance or roadside assistance. Our top picks all have plenty of add-ons in addition to basic coverage.
Progressive has a slew of available discounts — including one for adding a newly licensed teen driver to your existing auto policy (surprising, given that teenage drivers are among the riskiest to insure). But a policy loaded with discounts isn’t necessarily cheaper than a non-discounted policy, and the Texas Department of Insurance’s data on premiums show that Progressive is, on average, the most expensive for young drivers among the top five in Texas.
The reason car insurance is so cheap in Wisconsin is a bit of a mystery. While not a huge magnet for severe weather it does receive its fair share of snow in the winter and tornadoes in the summer. Flooding is not uncommon and rising rivers point to spring flooding this year. Flood damage is covered by comprehensive coverage, which is not required in most states, if you want your vehicle to be fully covered, you will need to carry this optional coverage.
We started by identifying Texas’ five biggest auto insurers by market share and comparing their financial strength, coverage options, and customer service using methodology similar to that in our review of the best car insurance providers. Then we checked J.D. Power and Consumer Reports to see how each company’s customers scored them on overall satisfaction and on the claims experience. Finally, we collected quotes for six hypothetical drivers, taking note of each company’s available endorsements and discounts.
To ensure that providers’ financial affairs were up to snuff, we looked at independent evaluations from insurance rating and credit rating agencies A.M. Best, S&P Global, Moody’s, and J.D. Power. While each agency has its own rating scale, we required companies to have A or “above average” ratings from all four — solid indications that companies are in great financial health. Acquiring ratings from all four agencies also indicates that companies care enough about their business’ reputation to apply for these voluntary review processes. For an industry that’s centered around the principle of being there when you need help most, we found this focus on transparency to be the mark of a good provider. Smaller companies like Good Sam or National Interstate may provide seemingly better discounts, but they tend to only submit themselves for review to one or two agencies.

One of the best ways to get cheap car insurance is by comparing car insurance quotes — and the companies offering them. To get you started, NerdWallet looked at car insurance prices across the country for different driver profiles and coverage levels to find the cheapest rates. We’ve sliced the data in several ways to give you an idea of average costs and what factors might nudge your car insurance rate up — or even better, down.
