Iowa Car Accident Laws

Iowa's rules are fairly standard, with one detail worth noting clearly: property damage gets a much longer window than personal injury — five years versus two.

If your car was damaged but you weren't hurt, Iowa quietly gives you two and a half times longer to bring that claim than an injury claim would get.

Statute of limitations: 2 years (5 for property damage)

Under Iowa Code §614.1(2), you generally have two years from the date of the accident to file a personal injury lawsuit. Property damage claims get a considerably longer window: five years.

Fault rule: modified comparative negligence, 51% bar

Under Iowa Code §668.3, you can recover damages if you're found 50% at fault or less, reduced by your percentage. At 51% or more, you recover nothing.

Insurance: at-fault system, 20/40/15 minimum

Iowa is an at-fault state. Minimum liability limits are 20/40/15: $20,000 per person and $40,000 per accident for bodily injury, plus $15,000 for property damage.

How this plays out in a real claim

Take an intersection collision where fault is genuinely disputed. If an insurer or court assigns you 40% of the blame, Iowa's rule still lets you recover 60% of your damages, and even at exactly 50% you still recover half. But at 51% or more, the claim is barred entirely — not reduced, eliminated. That one-point difference between 50% and 51% is exactly why insurers have a real incentive to push a borderline case just over the line rather than simply discount what they pay.

A mistake worth avoiding in Iowa

Because a single percentage point at the 51% threshold can be the entire difference between a reduced payout and nothing at all, careless statements at the scene or to an adjuster carry more weight here than in a pure comparative state. Avoid speculating about fault, even casually, until the full picture — police report, witnesses, any available footage — is in front of you.

If a government vehicle or agency was involved

Under the Iowa Tort Claims Act (Iowa Code Ch. 669), you must file a written notice of claim with the Attorney General before you can sue the state, and the deadline to do so is two years — the same as Iowa's general personal injury deadline, though the Attorney General's final decision on the claim can extend that window by up to six months. A separate, practical requirement worth knowing: Iowa law also requires you to report an accident involving a government vehicle to the authorities, and failing to do so can put your driver's license at risk, independent of anything to do with your injury claim.

If the crash resulted in a death

Iowa gives two years from the date of death for a wrongful death claim (Iowa Code §614.1), filed only by the estate's personal representative; there's no general damages cap. Iowa's distribution rule is specific: if there's a surviving spouse, child, or parent, damages for loss of services and support must be apportioned among them by the court based on each person's actual loss, and a parent's recovery for a child's death is subordinate to any recovery by the child's spouse or children.

Beyond the deadline and the fault rule

The statute of limitations and the fault rule above decide whether you have a claim and how much of it survives — they don't decide what the claim is actually worth, or whether it's worth handling yourself. For that, see our guides on what affects a settlement, who pays your medical bills while a claim is pending, and whether Iowa law makes a lawyer worth it for your specific situation.

When it's worth talking to someone

With a hard cutoff at 51%, how fault gets assigned in Iowa can be the entire outcome of a claim. A free, no-obligation conversation is worth having if fault is disputed.
