Iowa injury-crash notice and reporting duties: sources and limits

4 original questions with explanations and saved review. Immediate law-enforcement notice after an injury crash, the separate 72-hour report to DOT, the agency-investigation exception and a capable occupant’s reporting duty when the driver is physically unable.

Read each question’s conditions carefully. Requirements can differ by age, license and vehicle use. How we built this practice.

How we built this practice

Iowa Code 2026 sections 321.266 and 321.268 and the relevant 2026 Acts chapter 1118 clauses were read October 1, 2026. The Code PDF was generated December 9, 2025. The Act preserves these selected injury-report duties but conditions its reporting changes on March 1, 2027 or an earlier specified implementation statement.

The actual operative paragraphs and these original questions were directly read and independently reviewed October 1, 2026. Physical and printed Code pages 184–185 are recorded internally. A September 2026 proposed electronic-report rule is not treated as an implementation statement or a final rule.

What is not covered

Property-damage dollar thresholds, an uninsured-vehicle reporting trigger and electronic-only filing are not scored. Their 2026 amendment has a special applicability condition that this study does not establish. A call alone is not an agency investigation, and the written-report exception does not erase other crash-scene duties.

Practice and saved mistakes

The full and shuffled views reuse the same 4 questions. Separate technical numbered sets and mixed practice selections stay unchanged. My mistakes adds this local topic to the same CAR history, without mixing other vehicles or states.

Keep the scenario’s conditions in mind

Read the explanation after each answer, then retry any questions you missed.
