Wyoming uses fault-based claims, so whoever causes a crash pays for the other motorists' injuries and damage through their policy.

The legal minimum seldom pays for a serious crash, because hospital bills and a new car can top $50,000 in one crash.

Example: $30,000 car$1,200

  • A $39,500 car in Wyoming: around $1,580 in state tax
  • A $55,000 car in Wyoming: roughly $2,200 in state tax

A trade-in lowers the Wyoming driving laws: with $5,000 in trade on a $30,000 car, you owe around $1,000 instead of $1,200.
