Iowa Personal Auto Insurance and Rating Rules

Private-Passenger Auto — Iowa Specifics

Uninsured/Underinsured Motorist Coverage (Iowa Code 516A.1-2)

Iowa Code Chapter 516A requires every Iowa auto policy to offer UM and UIM coverage at limits at least equal to the policy’s bodily injury liability. The applicant may reject UM/UIM, but the rejection must be in writing under Iowa Code 516A.1-2. Silence does not equal rejection; an attempted oral or implied rejection that does not comply with the statutory writing requirement is ineffective.

Proof of Financial Responsibility (Iowa Code 321A.12)

Iowa Code 321A.12 sets the procedural rules for demonstrating financial responsibility through an SR-22 filing. The SR-22 must be maintained for the duration required by law (typically 2 years). The insurer must notify the Iowa DOT if the policy lapses.

Aftermarket Parts Regulation (Iowa Admin Rule 191-15.45)

Iowa permits the use of aftermarket crash parts in repair of private-passenger automobiles, subject to:

• Disclosure to the insured. The repair estimate must clearly identify any non-OEM parts.
• Quality standards. Aftermarket parts must be of like kind and quality to OEM parts.
• Insurer responsibility. The insurer is responsible for the cost of correcting any inadequacy in aftermarket parts.
• Consumer choice. The insured generally has the right to insist on OEM parts at additional cost if desired.

Iowa Automobile Insurance Plan / Assigned Risk (Iowa Code 515D.11)

Iowa’s AIP is the auto residual market. All Iowa auto insurers participate proportionally to their market share. Drivers apply through a producer; the producer must document that the voluntary market has declined the risk.

Transportation Network Companies (Iowa Code 321N.1(5); 321N.4(2)(a))

Iowa Code Chapter 321N regulates rideshare insurance. The statute defines three distinct periods of TNC activity, each with different insurance requirements:

• Period 1 — App on, no ride request accepted. Minimum primary auto liability at defined limits, plus UM/UIM.
• Period 2 — Ride accepted, en route to passenger. Higher limits — typically $1 million combined single limit.
• Period 3 — Passenger in vehicle. Same higher limits as Period 2.
• Coverage source. Either the TNC or the driver (or a combination) may carry the required coverage during each period. In practice, the TNC typically provides Period 2 and 3 coverage, and the driver’s personal auto carrier may extend Period 1 with a TNC endorsement.

CORE IDEA — Personal auto’s TNC gap

Standard Iowa personal auto policies typically exclude coverage when the vehicle is being used to transport persons for hire. Without specific TNC coverage, a rideshare driver in any of the three periods has no insurance. Iowa Code 321N forces both the TNC and the driver to ensure that gap is filled.

Rate Standards (Iowa Code 515F.4(1); 515F.5(1)(a))

Iowa rates must meet three standards: not excessive, not inadequate, not unfairly discriminatory. Iowa uses a file-and-use rate regulation system for personal lines: insurers file rates with IID and may begin charging them immediately, subject to IID’s after-the-fact disapproval authority.
