Strategic Transportation Safety Plan

2020-23 Colorado Strategic Transportation Safety Plan

The Strategic Transportation Safety Plan has been updated for 2020 to 2023. It is a statewide plan, intended for all Colorado stakeholders involved with transportation safety; it replaces the Strategic Highway Safety Plan (2014 -2019). The plan guides all Colorado agencies and other stakeholders in taking action on improving transportation safety – specifically in areas of leadership, safety culture, driver behavior, and infrastructure. The plan incorporates a "Zero Deaths" philosophy, and has identified 15 key strategies to target Colorado’s high and critical priority safety issues. Our goal is to reduce fatalities and serious injuries in Colorado by 15% by 2023.
