In Wyoming, a Fifth of the Coverage Available Goes Unbought

Two numbers exist for every state. What a complete package costs — liability, collision and comprehensive added together. And what drivers there actually spend on average.

The gap between them is coverage people chose not to buy.

The cheap states are where people buy least

This runs against intuition. You'd expect drivers to economise where insurance is expensive and buy everything where it's cheap. The opposite happens.

Wyoming and South Dakota have some of the lowest premiums in the country and the largest share of coverage left on the table. New Hampshire and Massachusetts cost more and drivers there buy almost the full package.

What's actually being skipped

Liability is mandatory almost everywhere, so the gap is collision and comprehensive — the two components that pay to fix your own car.

And those are optional in a specific circumstance: when you own the car outright. A financed or leased vehicle has a lender requiring full coverage as a condition of the loan. Once the loan is paid off, that requirement disappears and the decision becomes yours.

Which reframes the map. Wyoming and South Dakota are states with older, cheaper, fully-owned vehicles — the profile where dropping collision on a $4,000 truck is a completely rational decision. Massachusetts and New Hampshire have newer, more expensive, more heavily financed cars where nobody has the option.

When dropping collision makes sense

The standard rule: if the annual premium for collision and comprehensive exceeds about 10% of the car's value, you're paying a lot to insure a little.

On a car worth $4,000, full coverage at $400 a year buys you a maximum payout of $4,000 minus the deductible. Three years of premiums and you've paid for a third of the car you're insuring.

Drop it when: the car is worth under about $5,000, you own it outright, and you could absorb replacing it without borrowing.

Keep it when: there's a loan, the car is worth more than you could replace from savings, or you're in a high-theft or severe-weather area — comprehensive is the cheapest line on the policy and the one rising fastest, as we found in the 20% rise in three years.

Never drop liability to save money. It's the component that protects your assets rather than your car, and it's the largest share of the bill in expensive states for good reason — we broke that down in two thirds of a Florida premium.

Know what the car is worth first

The whole calculation depends on the vehicle's actual value, and that's where people get it wrong in both directions. A branded title changes the number substantially and also changes what an insurer will write. A VIN check shows title status and history, and our insurance cost pages give the premium for a specific model before you commit either way.
