Verified as of September 11, 2026

Fault system At-fault (tort)
Shared-fault rule Modified comparative (51% bar) Reduction, not a bar, until the claimant carries more than everyone else put together: «Contributory fault shall not bar recovery in an action by a claimant to recover damages for fault resulting in death or in injury to person or property unless the claimant bears a greater percentage of fault than the combined percentage of fault attributed to the defendants, third-party defendants and persons who have been released pursuant to section 668.7, but any damages allowed shall be diminished in proportion to the amount of fault attributable to the claimant» (§ 668.3(1)(a)). «Greater than» is the 51 % form, so a driver exactly half to blame still recovers half — the opposite of Kansas and Nebraska next door. The comparison is against the combined fault of all the defendants and released parties, not against each of them separately. A consortium claim is measured differently again: it is barred by the fault of the injured person, not of the family member bringing it (§ 668.3(1)(b)). Do not confuse either rule with § 668.4, which is a separate fifty-percent rule about joint and several liability among defendants.
Deadline to sue for vehicle damage 5 years from the accident [2] Five years for «those founded on unwritten contracts, those brought for injuries to property, or for relief on the ground of fraud … and all other actions not otherwise provided for in this respect» (§ 614.1(4)), running from accrual under the section’s own preamble («after their causes accrue, and not afterwards»). Iowa is one of the states where the two clocks genuinely differ, and the split is on the face of one section. Subsections 8 and 10, the stated exceptions, were not read and do not concern a motor claim.
Deadline to sue for injury 2 years from the accident [2] Two years from accrual for «those founded on injuries to the person or reputation, including injuries to relative rights, whether based on contract or tort, or for a statute penalty» (§ 614.1(2)). Read the words «whether based on contract or tort»: recasting an injury claim as a contract claim does not buy the ten years of § 614.1(5)(a). This is the shortest of Iowa’s three periods and the one that governs the claim most readers are making.
Deadline to sue your own insurer 10 years from the accident [2] Ten years for actions «founded on written contracts» (§ 614.1(5)(a)) — the policy itself. Two cautions travel with it. The policy may contract for a shorter suit-against-us period, and whether any Iowa statute sets a floor on how short that clause may be has not yet been verified against a primary text and is not stated here. And § 614.1(2) reaches an injury claim «whether based on contract or tort», so the ten years is a contract period and not a way round the two.
Insurer response deadlines — Acknowledge the claim 15 days from the claim [3] Plain, unqualified days — chapter 191—15 defines no «day» and uses «business day» only in its annuity divisions. «Upon receiving notification of a claim, an insurer shall, within 15 days, acknowledge the receipt of such notice unless payment is made within that period of time» (r. 191—15.42(1)), and the rule states in its own words that «insurer» means property and casualty insurers, so it reaches a motor claim. A second, continuing fifteen-day duty runs for the life of the claim: a reply is owed within fifteen days to every pertinent communication that reasonably suggests a response is expected (r. 191—15.42(3)).
Insurer response deadlines — Accept or deny 30 days from the claim [3] Thirty plain days from properly executed proofs of loss, and the duty is first-party by its own words: «Within 30 days after receipt by the insurer of properly executed proofs of loss, the first-party property claimant shall be advised of the acceptance or denial of the claim by the insurer», with any denial in writing citing the provision, condition or exclusion relied on (r. 191—15.41(2)). An extension is not open-ended: written reasons are owed within thirty days and again every forty-five days after (r. 191—15.41(3)). A third-party claimant’s equivalent is worded «within a reasonable time» and fixes no day count, so none is published for it.
Insurer response deadlines — Pay 30 days from the claim [3] Thirty plain days from affirmation of liability, not from notice: «The insurer shall affirm or deny liability on claims within a reasonable time and shall tender payment within 30 days of affirmation of liability, if the amount of the claim is determined and not in dispute» (r. 191—15.41(6)). The affirm-or-deny half of the same subrule fixes no day count at all and must not be read as thirty days. Where several coverages are involved, an undisputed portion under one of them should be tendered within thirty days if paying it would end the insurer’s known liability under that coverage.
Minimum liability coverage Bodily injury, per person $20,000 · Bodily injury, per accident $40,000 · Property damage $15,000 [1] Written out in words in the statute and transcribed here, not derived: «subject to limits exclusive of interest and costs, with respect to each such motor vehicle, twenty thousand dollars because of bodily injury to or death of one person in any one accident and, subject to said limit for one person, forty thousand dollars because of bodily injury to or death of two or more persons in any one accident, and fifteen thousand dollars because of injury to or destruction of property of others in any one accident» (§ 321A.21(2)(b)). PUBLISHED UNDATED, deliberately: the section’s own history line names no amending act after the 1981 codification other than 2022 Acts, ch 1021, § 78, and that act was not opened, so no effective date is stated rather than a guessed one. What makes these figures a purchase mandate rather than merely financial-responsibility amounts is § 321.1(24B)(a), which defines the compulsory product as liability cover «subject to minimum limits … in the amounts specified in section 321A.21 or specified in another provision of the Code, whichever is greater». The same 20/40/15 is stated a second time, as the proof-of-financial-responsibility definition, at § 321A.1(11) — and it is that subsection, not § 321A.21, by which § 516A.1 measures the UM/UIM floor.

Iowa is an at-fault state, and its compulsory-insurance section says so in the plainest terms of any state in its round: a person «shall not drive a motor vehicle on the highways of this state unless financial liability coverage … is in effect for the motor vehicle and unless the driver has in the motor vehicle the proof of financial liability coverage card issued for the motor vehicle» (§ 321.20B(1)(a)). What that coverage must be is defined at § 321.1(24B)(a) — a policy insuring «against loss from liability imposed by law», at limits not less than those in § 321A.21. Those limits are twenty thousand dollars for bodily injury to one person, forty thousand for two or more, and fifteen thousand for property damage (§ 321A.21(2)(b)). The section’s own history names no amending act after the 1981 codification, so the figures are published here without an effective date rather than with a guessed one. The positive evidence for «at-fault» is what is compelled — liability cover — rather than a claim that no first-party scheme exists anywhere in the Iowa Code: the Legislature’s own full-text search route returned an empty shell, so no such negative is asserted.

Shared fault in Iowa reduces rather than bars, up to a point. Contributory fault does not bar recovery unless the claimant bears a greater percentage of fault than the combined fault of all the defendants and released parties, and damages are diminished in proportion (§ 668.3(1)(a)). A driver held exactly half to blame therefore still recovers half. A claim for loss of services, companionship, society or consortium is measured by the fault of the injured person, not of the family member bringing it (§ 668.3(1)(b)). Joint and several liability is a separate fifty-percent rule and a different fifty from the first: it does not reach a defendant under fifty percent of the total fault at all, and above that it reaches economic damages only, never noneconomic awards (§ 668.4).

The two limitation periods genuinely differ. An action founded on injuries to the person must be brought within two years of accrual, whether it is framed as contract or tort (§ 614.1(2)); an action for injuries to property runs five years (§ 614.1(4)); and an action on a written contract — the policy itself — runs ten (§ 614.1(5)(a)). None of that displaces the notice your own policy requires, which falls due long before any of them, and whether any Iowa statute limits how short a policy’s suit-against-us clause may be has not yet been verified against a primary text and is not stated here.

The Insurance Division’s rules put real clocks on an insurer, and they apply expressly to property and casualty insurers. An insurer must acknowledge notice of a claim within fifteen days unless it pays within that time, and must reply within fifteen days to any pertinent communication that reasonably suggests a response is expected (r. 191—15.42(1), (3)). A first-party claimant must be told of acceptance or denial within thirty days after properly executed proofs of loss, in writing where it is a denial, citing the provision relied on (r. 191—15.41(2)); if the insurer needs longer it must say so with reasons within thirty days and again every forty-five days after (r. 191—15.41(3)). Payment is due within thirty days of affirmation of liability where the amount is determined and undisputed, while the duty to affirm or deny is fixed only as «a reasonable time» (r. 191—15.41(6)). All of these are plain days: chapter 15 defines no «day» and uses «business day» only in rules that have nothing to do with claims, so they are not the same duty as Kentucky’s business days or Nebraska’s working days. The statute behind the rules, § 507B.4(9)(j), fixes no day count of its own and frames the duties as a general-business-practice test. Iowa also prohibits deadline pressure on a third-party claimant rather than imposing a duty to warn: no insurer may suggest that a third party’s rights may be impaired if a form or release is not completed in time, except to state the limitation period (r. 191—15.41(5)).

Uninsured, underinsured and hit-and-run cover sits in every Iowa bodily-injury policy at not less than the 20/40 floor of § 321A.1(11), and comes out only if the named insured signs a written rejection «on a separate sheet of paper which contains only the rejection and information directly related to it» (§ 516A.1). Every Iowa policy must also carry the Division’s own mandated notice that «Uninsured/underinsured coverage does not cover damage done to your vehicle» — it pays only for bodily injury, and collision cover is what pays for the car (r. 191—15.10(1)). A crash causing injury or death must be reported to a sheriff, the state patrol or the nearest peace officer «immediately by the quickest means of communication»; a written report goes to the Department of Transportation within seventy-two hours where there is injury, death or apparent total property damage of $1,500 or more — unless a law enforcement agency investigated, in which case no report is owed (§ 321.266(1)–(2)). The dollar figure belongs to the written report, not to the call. Colliding with an unattended vehicle triggers its own duty with no threshold at all: stop, find the owner, or leave a written notice in the vehicle struck (§ 321.264). Whether inherent diminished value is recoverable in Iowa has not yet been verified against a primary text and is not stated here; a search of the whole text of chapter 191—15 for «diminut», «diminish» and «loss of value» returns no hit, and that silence is a fact about the regulation, not evidence that the loss is recoverable.

2 years from the accident (Iowa Code § 614.1(2), (4), (5)(a) (2026) — Periods of limitation — Two years from accrual for «those founded on injuries to the person or reputation, including injuries to relative rights, whether based on contract or tort, or for a statute penalty» (§ 614.1(2)). Read the words «whether based on contract or tort»: recasting an injury claim as a contract claim does not buy the ten years of § 614.1(5)(a). This is the shortest of Iowa’s three periods and the one that governs the claim most readers are making.).
