Manual on Uniform Traffic Control Devices
Design, Assets & Policy
The 11th edition of the Manual on Uniform Traffic Control Devices (MUTCD) was published in the Federal Register and approved by the Director of the Office of Federal Register with an effective date of January 18, 2024. CDOT Traffic Safety and Engineering Services Branch is leading the adoption plan, working with CDOT Regional Traffic Engineers, subject matter experts, and other State departments to review the updated MUTCD and ensure CDOT's policies, procedures, standards, and guidance is in substantial conformance with the 11th Edition MUTCD. We are expecting the National MUTCD and Colorado Supplement to be adopted by the Colorado Transportation Commission for use by January 18, 2026.
Strategic Highway Safety Plan
Safety Performance & Engineering
The 2025 Strategic Highway Safety Plan (SHSP) replaces the 2020 Strategic Transportation Safety Plan (STSP). The SHSP establishes a collaborative and shared vision and mission for transportation in Colorado and identifies key safety needs in Colorado for guiding investment decisions towards strategies and countermeasures with the highest potential to save lives and reduce serious injuries and fatalities on Colorado roadways.
Crash Data Dashboards
Collaboration between Safety Programs & Crash Data and Safety Performance & Engineering
Transportation safety is a top priority for Colorado. CDOT Traffic Safety & Engineering Services developed performance dashboards displaying all reporting public roadway crashes in Colorado to better understand numbers, causes, types, and locations of crashes in order to develop effective countermeasures and to meet performance targets.
Disclaimer: Colorado traffic crashes as presented in the dashboard are approximate and subject to change The official number of traffic fatalities in Colorado can be found on NHTSA's Fatality Analysis Reporting System (FARS) site.
