As it currently stands with Texas, in the event of an accident, there’s a one in seven chance that the other driver won’t be insured. Unless you’ve purchased uninsured/underinsured motorist (UM/UIM) coverage, that’s money out of your pocket. Texas’s minimum requirements also don’t account for comprehensive coverage, which you’ll definitely want to take into consideration, since the state ranks first for monetary losses from “catastrophes” like hail storms and hurricanes.
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.
Know when to cut coverage. Don’t strip away coverage just for the sake of cheaper insurance. You’ll need full coverage car insurance to satisfy the terms of an auto loan, and you’ll want it as long as your car would be a financial burden to replace. But for older cars, you can drop comprehensive and collision coverage, which only pay out up to your car’s current value, minus the deductible.
