When Crashes Happen
The timing of crashes showed some changes year-over-year, with the peak day for incidents shifting from Tuesday (995 crashes) in the prior period to Thursday (941 crashes) in the current period. The 5 p.m. hour remained the single busiest time for crashes in both January 2024 and January 2025. Weekday afternoons consistently saw the highest volume of collisions in both periods.

Crash Severity Breakdown
While the total number of crashes decreased, their severity profile shifted. The number of fatal crashes increased from 14 to 17, and the fatal crash rate rose from 0.25% to 0.41% of all incidents. The proportion of crashes involving any injury also saw an increase, climbing from 21.2% in January 2024 to 24.1% in January 2025, driven partly by a rise in the share of serious injury crashes from 1.1% to 1.5%.

Top Contributing Factors
The leading contributing factors for crashes changed significantly compared to the prior year. 'Driving too fast for conditions,' the top factor in January 2024 with 967 crashes, saw its count drop by 68.4% to 306 incidents. Consequently, 'Animal' became the primary factor in January 2025, with its crash count increasing by 38.7% from 401 to 556. Crashes involving 'Followed too close' also rose in count by 39.5%, from 294 to 410, making it the second-most cited factor.

Road & Environmental Conditions
Environmental conditions were markedly different between the two periods, strongly influencing crash patterns. In January 2024, crashes on 'Snow' (1,713) and 'Ice/frost' (1,230) road surfaces were predominant. In contrast, January 2025 saw most crashes occur on 'Dry' roads (2,537), with incidents on snowy or icy surfaces falling to 516 and 283, respectively. This shift aligns with the significant reduction in crashes attributed to driving too fast for conditions.

Vehicles & Demographics
The most common vehicle makes involved in crashes, Ford and Chevrolet, maintained their top rankings in both periods, though their total counts decreased with the overall trend. An analysis of person demographics shows a shift in age representation among those involved in crashes. The share of individuals aged 65 and older increased from 9.5% in January 2024 to 11.8% in January 2025, while the share for the 26-34 age group decreased from 16.4% to 15.0%.

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 2025-01-31
- Report generated: September 9, 2026
Data Coverage
- Reporting period: 2025-01-01 through 2025-01-31 (31 days)
- Geographic scope: iowa, IA
- Total crash records analyzed: 4,104
- Total persons involved: 7,200
- Total vehicles involved: 6,981
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.
