This tool provides public access to non-personal statewide law enforcement reported motor vehicle crash data from 2010 to the present. It's designed to help users examine and understand various aspects of vehicle crashes, from the types of incidents to the factors that contribute to them.
Accessing and Filtering Crash Data
Only 2000 crashes can be displayed at a time. To refine your search, filters can be used to change the results returned. Many filters allow for multiple selections. To add an option, click once; click again to remove it. Use the search box to quickly find values. To search by route, type directly into the route box to find matching locations. It is also possible to scroll through the options alphabetically. To remove a selected route, click the (x) next to it. Broad queries may return too many results to display. Click Run at the bottom of the Query Builder to run your query, or click the X in the upper right to go back.
Note: The map limits display to 5,000 crashes for performance reasons. If your query returns more than 5,000 crashes, a note will appear recommending you refine your query. Common ways to refine a query including narrowing the date range or towns selected. Reports are unaffected by this limit.
Examining Individual Crashes
To view more data about a specific crash, click on it. A popup will appear, and the crash will be highlighted in the table. If there is more than one crash at this location, the popup will display an arrow in the upper right corner. Click that arrow to cycle through the crashes.
You can also see the crash location by clicking the Street View link on the bottom of the popup information box for each crash. A new window will open Google Street View at the crash location, if available.

Customizing the Display
Click the Layers button in the upper right to toggle layers, themes, and basemaps. Multiple layers can be active at once, but only one theme and one basemap can be displayed at a time. If a theme has special symbols, a button for toggling the legend will appear next to the Layers button.
To print a map, use your browser's Print Preview to ensure the printed area is as desired.
Important Considerations
Note: Not all crashes have valid location data, and some may not be mappable through automated tools. The number of crashes not mappable will appear above the table.
While efforts are made to ensure data accuracy, errors and inconsistencies may occur. Contact the relevant authorities with any questions.
Searching and Adjusting the Table
Use the search box in the upper left of the table to search across all columns as you type. The green caret button in the upper right toggles the table layout between horizontal and vertical. It is also possible to resize the table by clicking and dragging an edge or corner. The table can only be moved in overlay mode (on larger screens). On small screens, the table is below the map and cannot be moved.

Reporting and Exporting Data
Each report has its own set of filters. To print a report, view it full screen, then print it using your browser's tools. Use the Copy or Download buttons on the data table to export data. All data returned by the current query will be exported.
Specific Crash Types and Definitions
Here are some key definitions related to crash types and factors:
- Fatal Crash: A crash involving a motorized vehicle on a public highway that results in one or more fatal injuries.
- Head On Crashes: A crash between two vehicles traveling in opposite directions on the same highway.
- Inattention: Includes crashes where the Primary or Secondary Contributing Circumstances-Driver was reported as "Inattention," including talking and eating.

- Injury-Suspected Serious: Any injury, other than a fatal injury, which prevents the injured person from walking, driving, or normally continuing activities they were capable of before the injury.
- Injury-Possible: Any injury reported or claimed which is not a fatal injury, serious injury, or minor evident injury.
- Injury-Untimely Death: A death occurring due to causes or injuries unrelated to the crash event.

Fatal crash reports are submitted to the database as soon as sufficient information is available. Due to the complexity of a fatal crash investigation, it may take 90 days or more to receive all data related to a crash. As a result, PQT query results may vary from other data sources.
Here's a summary of injury severity levels:
| Injury Type | Description |
|---|---|
| Fatal Injury | Results in one or more deaths. |
| Suspected Serious Injury | Prevents the injured person from continuing normal activities. |
| Suspected Minor Injury | Evident injuries such as lumps, abrasions, or bruises. |
| Possible Injury | Reported but not categorized as fatal, serious, or minor. |
| Untimely Death | Death due to causes unrelated to the crash. |
