The Idaho Transportation Department has created several Dashboards to help visualize and share crash reporting information with the public. These Dashboards can be found on the Idaho Highway Safety page, or can be accessed directly here.

Each of these Dashboards focus on a specific emphasis area and provide users with detailed, filterable information regarding each emphasis area. Currently, the following dashboards are available for use:

  • Crash Summary

  • Aggressive Driving

  • Bicycle Involved

  • Distracted Driving

  • Impaired Driving

  • Motorcycle Involved

  • Pedestrian Involved

  • Wild Animal INvolved

  • Mature Driver (Age 65+) Involved

  • Youth Driver (Ages 15-19) Involved

Navigating between Dashboards

By default, you will most likely view the Crash Summary dashboard when you open the Dashboards. You can easily navigate between the various dashboards by clicking on the Dashboard Dropdown located at the top of the screen, then selecting the desired Dashboard from the dropdown menu.

Note: switching between Dashboards will remove any filters you had applied.

How to Navigate a Dashboard

Each of the Crash Dashboards are composed of three main areas: The search bar, the filter sidebar, and the Metrics.

(The Summary tab of the Youth Driver Dashboard with the Search Bar (Green), Filter Sidebar (Blue), and Metrics (Orange) Highlighted.)

At the top of the Dashboard is the search bar. The search bar serves two main functions: it displays the current filters that are applied to the Dashboard, and it allows users to search for additional filters to apply to the Dashboard.

When you open the Dashboard, there is automatically a date range filter applied. This can be modified by clicking on the date range, and selecting a new date for the filter.

Any time a new filter is added, either through the Search Bar, the Filter Sidebar, or by clicking on a chart, it will be displayed in the Search Bar.

Any filter can be modified by clicking on any part of the filter. In the example below, I am changing the year range from 2015 - 2019, to 2016 - 2019.

Any filter can be removed by clicking on the X next to the filter.

The filter bar will remain persistent across a Dashboard, meaning if you apply a filter, you can navigate between tabs in that dashboard without having to reset your filters each time.

Note that filters are reset each time a new Dashboard is opened.

Filter Sidebar

The Filter Sidebar contains many of the most frequently used filters available in easy-to-use dropdown menus. To apply a filter from the sidebar, simply click on the dropdown menu, and select the filter from the list. You can either scroll through the list and select the option, or begin typing to easily find what you are looking for.

In the example below, I am adding a city filter to display only the information for the city of Meridian.

(Selecting the City of Meridian from the Filter Sidebar in the Total Youth Driver Data Tab of the Youth Driver Dashboard.)


The Metrics section of a Dashboard displays the data in a chart, graph, or metric. Each component of the Dashboard updates automatically to reflect any filters that are applied to the Dashboard. When you first open a Dashboard, only a date-range filter is applied, as well as a filter to remove all non-traffic crashes, so you are viewing the crash data for the entire state of Idaho, in the specified date range.

(The Map View Tab of the Youth Driver Involved Dashboard with the default year filters applied.)

When a location filter is applied, each metric updates to reflect the newly applied filter. In the example below, I am adding a location filter for Twin Falls County to the dashboard. Notice that the same metrics are present in both images, only the data has updated to reflect the filter change.

Additionally, most of the charts in a Dashboard can serve as interactive filters. By clicking on an element of a chart, you can apply the selected element as a filter to a chart. In the example below, I am clicking on the Angle Crash Type partition, and it is applied to the entire Dashboard as a filter. Notice the color change in the selected element of the chart (the other partitions grey out), as well as the additional filter in the search bar at the top of the screen.

Clicking on the same element again will remove the filter.

Most dashboards contain different tabs of data, users can navigate between tabs of data by clicking on the tab, located just beneath the search bar. Switching tabs will not impact any filters you may have applied. It will only change the charts that are displayed in the metrics section of the Dashboard.

Advanced Filtering

Additional filters can be added using the search bar by clicking on the Add Filter button, and typing to search for a filter. In the example below, I am adding a filter to only display crashes in which Alcohol was involved by typing the word Alcohol into the filter bar, and selecting Alcohol Related from the dropdown, and selecting True.
