Accessing and understanding traffic crash data is crucial for improving road safety and informing policy decisions. The Missouri State Highway Patrol provides a comprehensive suite of online tools, effectively a Cars And Stars Online Reporting Tool, designed to offer detailed insights into traffic incidents across the state. This system, built upon the Missouri Crash Analysis Reporting System (MOCARS), allows users to explore various facets of crash data, from high-level summaries to granular details.
Missouri law enforcement agencies are mandated to report traffic crashes resulting in fatalities, injuries, or significant property damage to MOCARS. This ensures a robust and reliable database for analysis. It’s important to note that while MOCARS includes crashes occurring off public roadways, these are excluded from statistical analyses to maintain data integrity for public safety purposes. Additionally, minor incidents with damages under five hundred dollars may also be included if reported.
The online platform offers several distinct report types, each catering to different analytical needs:
- Traffic Safety Compendium: This report provides a year-end overview of traffic statistics, offering a broad perspective on safety trends throughout Missouri.
- Crash Characteristics Summary Reports: For those seeking deeper statistical analysis, these reports detail various crash and driver characteristics. They are invaluable for identifying patterns and risk factors associated with traffic incidents.
- Police Traffic Safety Reports: Focusing on trends over time, these reports analyze three-year patterns of specific crash characteristics. This longitudinal view is essential for evaluating the effectiveness of safety initiatives and identifying emerging issues.
- Traffic Crashes Online Mapping: This interactive tool allows users to visualize crash data geographically. By selecting specific parameters, users can generate maps displaying crash locations and related data, aiding in the identification of high-incident areas.

- Static MSHP Crash Reports: These pre-generated reports rank counties and cities based on the frequency of total, fatal, and disabling injury crashes. This provides a quick overview of high-risk areas across the state.
- Online Traffic Crash Reports: This search tool is designed for users needing to identify individuals involved in recent crashes (within the last 29 days). It offers a direct way to access information about specific incidents.

It is crucial to understand the data’s context. The statistical analyses available are based on Missouri Uniform Traffic Crash Reports (MUCRs) that have been thoroughly reviewed and approved by the Missouri State Highway Patrol. While crash data is typically accessible for analysis within a week, complex investigations may extend this timeframe.

Furthermore, users should be aware that the MUCR format has evolved over the years, with revisions in 2012 and 2024. While data conversions are implemented to accommodate these changes, caution is advised when comparing analytical results across different reporting periods (2002-2023) with original MUCR data to ensure accurate interpretation.
In conclusion, the Missouri State Highway Patrol’s online platform serves as a valuable cars and stars online reporting tool, providing a range of resources for accessing and analyzing traffic crash data. By offering various report types and search functionalities, it empowers researchers, policymakers, and concerned citizens to gain meaningful insights into traffic safety within Missouri, ultimately contributing to safer roads for everyone.
