When Crashes Happen
The temporal patterns of crashes shifted between the two periods. In 2025, the highest crash volumes occurred on Friday and Saturday (41 crashes each), a change from 2024 when Wednesday was the peak day with 58 crashes. Similarly, the peak hour for collisions moved from 6 p.m. in 2024 (28 crashes) to 3 p.m. in 2025 (24 crashes).

Crash Severity Breakdown
While the total number of crashes declined, the severity of crashes increased proportionally in 2025. The share of fatal crashes rose from 0.6% to 0.8% of all incidents, and the share of serious injury crashes increased significantly from 1.9% to 3.8%. This shift is also reflected in the decrease in the proportion of no-injury crashes, which fell from 74.7% of all crashes in 2024 to 68.9% in 2025.
Severity is per crash event (most severe injury). 2 fatal crash events resulted in 3 persons killed.

Top Contributing Factors
Collisions involving animals remained the top contributing factor in both years, though the count dropped from 61 in 2024 to 39 in 2025. 'Followed too close' moved up in the rankings, with incidents increasing from 11 to 19. Conversely, crashes attributed to 'Driving too fast for conditions' decreased from 22 to 12. 'Ran Stop Sign' also saw an increase in count, rising from 14 incidents in the prior year to 18 in the current year.

Road & Environmental Conditions
Crash conditions remained largely consistent between 2024 and 2025. In both periods, the majority of incidents occurred during daylight hours, on dry road surfaces, and in clear weather. For example, crashes in daylight accounted for 64.3% of the total in 2025, compared to 62.7% in 2024. There was no significant year-over-year shift in the proportion of crashes occurring under adverse weather, lighting, or road surface conditions.

Vehicles & Demographics
The top vehicle makes involved in crashes remained consistent, with Ford and Chevrolet accounting for the highest numbers in both years. In 2025, Chevrolet-badged vehicles (CHEV/CHEVROLET) were involved in 98 crashes, while Ford was involved in 58, a reversal from 2024 when Ford led with 96 vehicles to Chevrolet's 85. Regarding driver and passenger demographics, the 65+ age group saw a notable decrease in involvement from 112 persons in 2024 to 73 in 2025. Conversely, involvement for the 16-20 age group increased from 56 to 64 persons.

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: 238
- Total persons involved: 424
- Total vehicles involved: 401
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.
