Crash Severity Breakdown
While the number of fatal crashes remained unchanged at one for both periods, the fatal crash rate increased from 0.85% to 1.01% due to the lower overall crash total in the current year. The distribution of injury severity shifted, with two serious injury crashes recorded in 2025 compared to none in 2024. Conversely, crashes resulting in 'Possible Injury' saw a significant decrease, dropping from 19 incidents to 8.

Top Contributing Factors
The leading contributing factors for crashes shifted between the two periods. 'Failure to yield right-of-way from a stop sign' became the top factor in 2025, with incidents increasing in count from 9 to 15. The previous leading cause, 'Animal' involvement, decreased from 20 to 14 incidents. Another significant change was the reduction in crashes due to 'Followed too close,' which dropped from 15 incidents to 6. Conversely, crashes from 'Ran Stop Sign' increased from 2 to 6.

Road & Environmental Conditions
The majority of crashes in both periods occurred in clear weather and on dry roads, with the proportion of crashes under these conditions remaining relatively stable. A significant shift was observed in lighting conditions, as the number of crashes occurring in the dark decreased from 21 in the prior period to 8 in the current period. Correspondingly, crashes in daylight accounted for 73.7% of all incidents in 2025, up from 61.5% in 2024.

Vehicles & Demographics
Ford and Chevrolet remained the top two vehicle makes involved in crashes for both periods, though both saw a decrease in raw numbers, with Ford-involved vehicles dropping from 49 to 35 and Chevrolet from 26 to 23. An analysis of persons involved in crashes shows a shift in age demographics. The number of individuals in the 55-64 age group increased from 21 to 28, and the 65+ group grew from 33 to 35, indicating a higher count of older individuals in the current period's crashes.

Data Sources & Methodology
Primary Data Source
All crash data in this report is sourced from Iowa Crash Data, accessed programmatically via the ArcGIS Open Data API (SODA). This dataset contains official police-reported motor vehicle traffic crash records maintained by the reporting jurisdiction's law enforcement agency. Records are published to the open data portal by the municipality and are subject to the portal's terms of use.
Data Retrieval
- Access method: ArcGIS Open Data API (SoQL queries)
- Data format: Structured JSON via REST API
- Record types queried: Crash events, person records, and vehicle unit records
- Date filter applied: 2025-01-01 through 2025-12-31
- Report generated: September 9, 2026
Data Coverage
- Reporting period: 2025-01-01 through 2025-12-31 (365 days)
- Geographic scope: iowa, IA
- Total crash records analyzed: 99
- Total persons involved: 175
- Total vehicles involved: 170
Analytical Methodology
- Severity classification: Uses the KABCO injury scale (K=Fatal, A=Incapacitating injury, B=Non-incapacitating injury, C=Possible injury, O=No injury/property damage only), the standard classification in U.S. Model Minimum Uniform Crash Criteria (MMUCC). Severity is assigned per crash event based on the most severe injury in that crash. A single fatal crash (K) may involve multiple fatalities; therefore the "Persons Killed" count in the headline KPIs may differ from the "Fatal" crash count in the severity breakdown.
- Contributing factors: Reflect the officer-determined primary contributory cause recorded at the time of the crash report. These are preliminary determinations and may not reflect final investigation findings.
- Hit-and-run classification: Based on the hit-and-run indicator field in the official crash report, as determined by the responding officer at the scene.
- Temporal analysis: Day-of-week and hour-of-day distributions are computed from the crash date/time timestamp in each record.
- Demographics: Age and sex distributions are drawn from person-level records linked to each crash event. A single crash may involve multiple persons.
- Vehicle data: Make information is drawn from vehicle unit records linked to each crash event.
- AI commentary: Narrative sections are generated by Google Gemini (large language model) based on the structured data. Commentary is descriptive, not predictive, and should not be interpreted as expert opinion.
Limitations & Disclaimers
- Only crashes reported to and documented by law enforcement are included. Minor incidents, unreported crashes, and near-misses are not captured in this dataset.
- Data reflects conditions at the time of the initial police report and may be subject to subsequent corrections, reclassifications, or supplements by the reporting agency.
- Open data portal records may experience a publication lag - recently occurring crashes may not yet appear in the dataset at the time of report generation.
- AI-generated commentary is produced by a large language model and is intended to highlight patterns in the data. It does not constitute legal, medical, or professional analysis.
- Percentages are calculated from reported data and are subject to rounding.
