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.

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.

It is difficult to project whether rates will continue to rise, as there are so many factors that determine car insurance pricing. If loss-causing trends continue—such as more expensive vehicle repairs, distracted driving crashes and vehicle damage due to extreme weather—consumers should see premiums increase. However, if these trends reverse and there are fewer accidents and milder weather, then car insurance rates could plateau or even decrease.

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.
Regardless of how often you use your RV, Safeco is worth a look. Safeco offers coverage for anyone who lives in an RV fewer than 250 days (about eight months). While this won’t cover policyholders who live in their RV full-time, it serves as a nice middle-ground for people who only plan to store their RV away during the winter months, for instance.
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.
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.
