If you’ve ever compared car insurance rates, you know how many options are available. Depending on a variety of individual rating factors, certain companies will price your insurance differently. You could end up paying more by choosing the wrong company or failing to compare enough companies. We've outlined the factors that go into your car insurance premiums, as well as some tips for how to find the best possible rates. Let’s get started.
The big reason that D.C. makes the cut is population density. The entire district is basically an urban area, which leads to higher insurance rates. According to Census information, D.C has a population density of 11,020 people per square mile. While this number is certainly smaller than New York City, which clocks in at 28,256 people, it puts it well above other large cities, such as Houston and even Los Angeles.

A slew of devastating natural disasters struck the U.S. in 2018, resulting in insurance claims that cost billions of dollars. While home insurers are usually hit the hardest by these disasters, auto insurers are affected as well. Additionally, distracted driving has led to an increase in accidents on the road. These factors, coupled with the fact the the auto industry is moving toward higher-tech cars that are more expensive to repair, contribute to high losses for insurers.
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.
If you live in your RV full-time for more than six months of the year, Allstate will not be able to insure your RV. Because of that, Allstate is a more suitable provider for people who only use their RVs occasionally: Its policies include basic coverage, sound system coverage, personal belongings coverage, medical payment, roadside assistance, and rental reimbursement.

State Farm boasts a solid score in J.D. Power’s Customer Claims Satisfaction rating among our top picks (three out of five) and sits above industry average. That means that once you do file a claim, you can expect a smooth experience. If a positive customer experience is especially important to you, State Farm is likely to deliver superior service.
In most states, a DUI is the most costly violation you can receive. Moreover, in states like California, it will stay on your insurance record for 10 years! Based on our analysis of the most popular car insurance companies, this would set you back an average of $1,200 in insurance rate increases during that 10-year period. To limit costs, do your due diligence and shop around: Progressive and USAA are the cheapest insurance options after a DUI — consider starting with those providers.
But liability coverage levels come in threes — you’ll probably see something like 50/100/50 up to 250/500/250 in typical policies. You can think of these limits like: individual injuries / total injuries / property damage. Insurers are a little more technical, calling them bodily injury liability, total bodily injury liability and physical damage liability.
