Iowa Tort System

  • The at-fault driver is responsible for paying damages
  • Injured parties file claims against the at-fault driver's insurer
  • Third-party claims are the standard process

Exam Tip: Iowa's 20/40/15 minimums are among the lower limits nationally. A proposed law may increase these to 50/100/25, but as of 2026, the 20/40/15 minimums remain in effect.
