What is the minimum car insurance required in Iowa?

$20,000 for bodily injury to or death of one person in any one accident, $40,000 for bodily injury to or death of two or more persons, and $15,000 for injury to or destruction of the property of others.

Why is Iowa’s minimum lower than most states?

Iowa’s 20/40 bodily injury floor sits below the 25/50 most states use and has not been raised in a long time. Against current medical costs it is thin — a single serious injury can exhaust the $20,000 per-person limit.

Is car insurance cheap in Iowa?

Iowa is consistently among the least expensive states in the country. The useful consequence is that raising your limits well above the state minimum costs less here in absolute dollars than almost anywhere else.

Is hitting a deer covered in Iowa?

Under most policies an animal collision is a comprehensive claim rather than a collision claim. Deer collisions are common across Iowa, so it is worth confirming how your policy treats them — a liability-only policy covers neither.

What happens if I drive without insurance in Iowa?

Driving without financial liability coverage carries a criminal penalty in Iowa, not merely a civil fine, alongside the licence and registration consequences.

Auto insurance in Iowa: what’s required, and what isn’t

By Gaby Valencia, Insurance Content Editor

Last verified August 26, 2026

Iowa requires 20/40/15 — one of the lowest bodily injury floors in the country, below the 25/50 most states use. Iowa is also consistently among the cheapest states in the nation for auto insurance, and those two facts together produce the clearest recommendation on this site: buying substantially more coverage than Iowa requires costs very little, and the state minimum is thin against any serious injury.

What Iowa requires you to carry

Minimum liability limits in Iowa — 20/40/15
Bodily injury, per person	$20,000
Bodily injury, per accident	$40,000
Property damage, per accident	$15,000

These are floors, not recommendations. Iowa sets the minimum a driver may legally carry. It does not assess whether that amount would cover a claim you caused. Anything above your limits is your personal exposure.

How Iowa enforces it

Iowa requires proof of financial liability coverage under Iowa Code § 321.20B, and drivers must be able to produce it on request. Driving without insurance carries a criminal penalty in Iowa rather than a purely civil one.

How rates are set in Iowa

Iowa is an at-fault state. The driver responsible for a crash is responsible for the resulting injury and property damage, and their liability limits cap what the insurer pays on their behalf.

The Iowa Insurance Division regulates carriers, publishes consumer material and handles complaints, while the Department of Transportation owns driver records and financial responsibility. The statutory framework sits in Iowa Code chapters 321 and 321A — § 321.20B for the proof requirement and § 321A.21 for what a motor vehicle liability policy must contain.

Iowa is a competitive-rating state with a strong regional and mutual carrier presence alongside the national names, which is part of why the market prices as low as it does.

Credit-based insurance scores in Iowa

Iowa permits credit-based insurance scores in rating. Iowa premiums run among the lowest in the country, which compresses the absolute dollar impact of any single rating factor — and makes moving above the state minimum unusually affordable.

What actually moves your premium here

Iowa has one of the lowest bodily injury floors in the country

At $20,000 per person and $40,000 per accident, Iowa’s bodily injury minimum is below the 25/50 that most states use. It has not moved in a very long time, and against current medical costs a $20,000 per-person limit is exhausted by a single serious injury.

Cheap premiums make higher limits nearly free

Iowa is consistently among the least expensive states in the country for auto insurance. That has a useful consequence: the incremental cost of moving from 20/40/15 to something substantial is smaller in absolute dollars here than almost anywhere. The gap between what Iowa requires and what an Iowa driver could comfortably afford is one of the widest in the nation.

Deer collisions and severe weather

Iowa combines high animal collision frequency with an active severe convective season — hail, high wind and derechos. Under most policies both are comprehensive claims rather than collision claims, and a liability-only policy responds to neither.

Rural severity with limited metro offset

Outside Des Moines and the Cedar Rapids corridor, Iowa is rural with long two-lane distances. Crashes are infrequent and severe when they happen, which is exactly the profile a $20,000 per-person bodily injury limit handles worst.

Comparing carriers in Iowa

Price the same driver at 20/40/15 and again at 100/300/100 before deciding. In one of the cheapest states in the country the absolute difference is often small enough to make the decision obvious — and the state minimum is genuinely thin.

Include Iowa’s regional mutuals in your comparison. They rarely advertise nationally but compete hard on multi-vehicle households and low-mileage drivers.

One habit matters more than any single carrier choice: re-check every year or two, and again after anything that changes your risk profile — a move across town, a new vehicle, a driver added or removed, or a violation ageing off your record. Carriers re-weight their rating factors continuously, so the one that priced you best three years ago is often not the one that prices you best today.

If you need an SR-22 in Iowa

Iowa requires proof of financial responsibility to be filed after certain suspensions, including crashes while uninsured and OWI convictions. Your insurer files it with the Department of Transportation. Confirm the period for your case with Iowa DOT, since it runs from your reinstatement date.
