Wyoming is famous for cheap car insurance. Jackson didn't get the memo. Full coverage here runs about $2,056 a year, nearly double the state average of $1,148, making it the most expensive town in Wyoming to insure a car.

That's an odd fact for a town of only about 10,500 year-round residents. But Jackson isn't really a town of 10,500 — it's the front door to Grand Teton and Yellowstone, a second-home market for people who don't blink at seven-figure real estate, and the only real gateway through a mountain pass that deer and moose treat as their own commute.

The Most Expensive ZIP Code in Wyoming

Jackson and the surrounding Teton County ZIP codes consistently top Wyoming's insurance-cost rankings, and the reasons track closely with the town's broader economy. Housing costs here are famously the highest in the state, repair and labor costs follow the same curve, and a market flush with expensive vehicles — pickups, SUVs, and plenty of luxury and off-road trims — raises the average claim payout insurers plan around.

  • Cost of living: Jackson runs roughly 40% above the national average, and vehicle repair costs move with it.
  • Vehicle mix: a heavier share of trucks, SUVs, and higher-value vehicles than a typical Wyoming town.
  • Limited local competition: fewer repair shops and body shops in a remote valley can mean higher labor rates per job.

Teton Pass: A Wildlife Gauntlet

The stretch of highway over Teton Pass, connecting Jackson to Victor and Driggs on the Idaho side, has one of the worst wildlife-vehicle collision records in the region. Citizen-tracked data going back to 1991 has logged hundreds of collisions on just a few miles of that pass, overwhelmingly mule deer and moose.

Zoom out to all of Teton County and the estimate runs to 200 to 300 large-animal collisions a year, with wildlife biologists suspecting the true number is two to four times higher once unreported strikes are factored in. Those are comprehensive claims, not collision or liability, and they're a meaningful reason full coverage costs so much more here than a bare-minimum policy would suggest.

A Tourist Flood on a Two-Lane Town

Jackson's road network wasn't built for its actual traffic load. The highways feeding town — US-26, US-89, and US-191, plus the routes into Grand Teton and Yellowstone National Parks — see daily volumes that swing from around 1,500 vehicles on a quiet winter stretch to more than 23,000 a day at the height of summer.

That's rental cars, RVs, out-of-state drivers unfamiliar with mountain roads, and ski traffic in winter, all funneling through a town whose permanent population wouldn't otherwise justify that kind of exposure. Insurers weigh that seasonal crush heavily when pricing policies in Teton County.

Wyoming's Coverage Requirements

  • Minimum liability: 25/50/20 ($25,000 bodily injury per person, $50,000 per accident, $20,000 property damage)
  • Fault system: At-fault (tort state), no PIP requirement
  • Uninsured motorist coverage: Offered but not mandatory — can be declined in writing
  • Regulator: Wyoming Department of Insurance

Those minimums apply the same in Jackson as anywhere else in the state — they just don't do much to explain why premiums here run so far above them. If you're weighing whether the state floor covers what you're actually driving through, our minimum vs. full coverage guide breaks down the trade-offs.

Jackson will probably never be a cheap place to insure a car. Between the wildlife on Teton Pass, the summer traffic, and the town's own cost structure, that's mostly baked in. Shopping a few quotes before renewal is still the one lever a driver here fully controls.
