Minimum Car Insurance Requirements in Iowa

If you drive in Iowa, state law sets a floor on the liability insurance you have to carry, and that floor is lower than what most drivers actually need. Here is exactly what Iowa requires, what each number means, and what happens if you skip it.

The 20/40/15 minimum

Iowa requires every registered vehicle to carry liability coverage of at least $20,000 for bodily injury or death of one person in a crash, $40,000 for bodily injury or death of two or more people in the same crash, and $15,000 for damage to someone else's property.¹² Agents write that as 20/40/15. The limits come from Iowa Code section 321A.21, and the Iowa Insurance Division lists the same three figures on its consumer auto page.¹²

It helps to know what each number does. The $20,000 is the most the policy pays any single injured person. The $40,000 is the total available for everyone hurt in one crash, no matter how many people that is. The $15,000 covers the other driver's vehicle or other property you damage.

Liability coverage pays other people when you are at fault. It does not pay for your own injuries or your own car. If you rear-end someone and total their vehicle, your property-damage limit is what covers it. If that limit is $15,000 and the car is worth more, you can be personally on the hook for the rest.

Why the minimum is often not enough

Iowa is an at-fault (tort) state.² The driver who caused the crash, through their insurer, pays for the harm. Iowa also uses modified comparative fault: you can recover damages only if you are 50 percent or less to blame, and your award is reduced by your share of the fault. At 51 percent, you recover nothing (Iowa Code 668.3).³

Medical bills and lost wages from a serious crash routinely run past $20,000. When the at-fault driver carries only the state minimum, an injured person is left chasing the gap. That is why Iowa builds a second layer of protection into every policy.

Uninsured and underinsured motorist coverage comes built in

Every auto liability policy issued in Iowa automatically includes uninsured motorist (UM) and underinsured motorist (UIM) coverage, at limits equal to your liability coverage, under Iowa Code chapter 516A.⁴ UM pays when the at-fault driver has no insurance or flees the scene. UIM pays when the at-fault driver's limits are too low to cover what you lost.

You can turn this coverage down, but only in writing. Iowa Code 516A.2 requires the rejection to be signed by the named insured on a separate sheet of paper that contains only the rejection and information directly related to it.⁴ Without that signed form, the coverage applies even if it is not printed on your declarations page. Given how many Iowa drivers carry only 20/40/15, keeping UM/UIM is one of the more valuable lines on your policy.

PIP is not sold here, and MedPay is optional

Because Iowa is a pure at-fault state, insurers here generally do not sell personal injury protection (PIP), the no-fault coverage that is standard in some other states.² Iowa does not require it. Medical payments coverage (MedPay) is an optional add-on that pays your own medical bills regardless of who caused the crash, but no law requires it and there is no statutory deadline attached to it.

You have to carry proof, and driving without it is a crime

Iowa Code 321.20B makes it illegal to drive unless financial liability coverage is in effect for the vehicle, and it requires you to carry the proof-of-coverage card, on paper or on your phone, in the car.⁵ An officer can ask to see it at any stop.

Driving without coverage is a simple misdemeanor. The scheduled fine is $325, and it climbs to $645 if the violation is discovered in connection with a crash.⁵ On top of the fine, the state can remove your registration plates and the registration receipt and impound the vehicle.⁵

What happens after a crash if you were uninsured

Iowa's financial responsibility law has teeth. Under Iowa Code 321A.5, once the DOT receives a report of a crash that caused bodily injury, death, or at least $1,500 in property damage to any one person, it will suspend the license and all registrations of every uninsured driver and owner involved, unless that person posts security large enough, in the department's judgment, to cover any judgment from the crash.⁶ Drivers who had a liability policy in force at the time of the crash are exempt from that security demand.⁶

To get your license back after a financial-responsibility suspension, you file an SR-22, which is proof from an insurer that you carry at least the state minimum. Iowa requires the SR-22 to stay on file for two years, and any lapse in that period triggers another suspension.⁷ If you would rather not go through an insurer, Iowa lets you post a surety bond or securities worth $55,000 instead.⁷ Either way, you can only drive and register vehicles listed on that filing.⁷

The limits nearly changed in 2025

Lawmakers know 20/40/15 is thin. In the 2025 session, House File 6 and its Senate companion, Senate File 119, proposed raising the minimums to 50/100/25, meaning $50,000 per person, $100,000 per crash, and $25,000 for property damage.⁸ Neither bill became law, so 20/40/15 is still the requirement in 2026.²⁸

Iowa already demands higher limits from one set of drivers. Under Iowa Code 321N.4, a rideshare driver who is logged into an app and waiting for a request must carry 50/100/25, and once a passenger is in the car the required coverage jumps to $1 million.⁹ The Iowa DOT spells the same tiers out on its paid rideshare page.¹⁰ It is a useful benchmark: the state considers 50/100/25 the appropriate floor for a working driver, while ordinary drivers can still legally carry less than half of that.

After an Iowa crash

Whether the other driver was well insured or barely covered changes how you pursue a claim. If the at-fault driver carried only the state minimum and your injuries cost more than $20,000, your own UM/UIM coverage may be the difference between being made whole and eating the balance. If your vehicle lost resale value even after a solid repair, that is a separate claim; see our Iowa diminished value guide. You will also want the official crash report for your file, which you can pull through our Iowa crash reports page.

If you are trying to figure out whether the other driver's coverage will be enough, or an insurer is leaning on Iowa's 51 percent fault rule to cut your recovery, it can help to talk with an Iowa attorney. Keep the clock in mind: Iowa's deadline to sue for personal injury is two years from the crash date under Iowa Code 614.1(2), so do not let a coverage dispute quietly run past it.¹¹
