Car insurance is the bill nobody shops until it hurts. You get quoted a number when you buy the car, it renews itself quietly every six months, and the only time you question it is when it jumps.
What makes it worth questioning: the same driver with the same car pays wildly different amounts depending on which side of a state line they sleep on.
Twice the price, same country
Full coverage averages $1,994 a year in Florida and $926 in Maine. Not a difference in driving habits — a difference in state insurance markets, litigation rates and weather risk.
| State | Full coverage / year | vs US average |
|---|---|---|
| Florida | $1,994 | +39% |
| Louisiana | $1,979 | +38% |
| New York | $1,896 | +32% |
| US average | $1,438 | — |
| North Dakota | $961 | -33% |
| Vermont | $958 | -33% |
| Maine | $926 | -36% |
The national average sits at $1,438, and it breaks down in a way most people never see: $737 of that is liability, $464 is collision, and only $238 is comprehensive. Which matters, because those three parts behave very differently.
The part you actually control
Liability is set by law and by your state's claim environment — you're not negotiating that. Collision and comprehensive are the ones tied to your specific car, and that's where the choice sits.
Collision alone is nearly a third of the bill, and it scales with what your car costs to repair. This is why two people in the same town with the same record can pay very different premiums: an expensive-to-fix model carries an expensive-to-fix premium. You can see how models compare on our insurance cost data before you buy, which is the only moment you fully control it.
Comprehensive — theft, weather, a deer at dusk — is the smallest slice at $238. On an older car it's often the first thing worth dropping, though not in a hail or flood state.
What I'd do
If you're moving, look up the destination state before you budget: a Maine-to-Florida move roughly doubles this line item, and nothing about your driving changed.
If you're buying, check the insurance profile of the model alongside the price. A car that's $2,000 cheaper but $400 a year dearer to insure gives that back in five years — and it's worth pairing that with what it loses in value over the same period. The cheap car isn't always the cheap car.
