NerdWallet compared quotes from these insurers in ZIP codes across the country. Rates are for policies that include liability, collision, comprehensive, and uninsured/underinsured motorist coverages, as well as any other coverage required in each state. Our “good driver” profile is a 40-year-old with no moving violations and credit in the “good” tier.
You’ll notice that none of that liability coverage pays for your car or injuries, nor for any injuries your passengers sustain if you cause a wreck. This is why many people — particularly those whose car isn’t yet paid off — want “full coverage” car insurance. This isn’t actually a type of coverage, but instead typically refers to policies that include liability coverage, plus comprehensive and collision coverages.
NerdWallet averaged rates for 40-year-old men and women for 20 ZIP codes in each state and Washington, D.C., from the largest insurers, up to 12 in each state. “Good drivers” had no moving violations on record and credit in the “good” tier as reported to each insurer. For the other two driver profiles, we changed the credit tier to “poor” or added one at-fault accident, keeping everything else the same. Sample drivers had the following coverage limits:
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.

Collision and comprehensive insurance are two optional types of auto insurance where your insurer pays for repairs to your vehicle. While there are other optional auto insurance coverages, liability, comprehensive, and collision are three of the most common. These coverages work hand-in-hand to repair or replace most of the damages to your car. It's important to know the difference, and make sure you're adequately covered.
