As of 2025, the right turn on red rule in Colorado remains largely unchanged at the state level, but there are ongoing discussions and potential changes at the local level, particularly in cities like Denver.
Current Rule
- General Practice: In Colorado, drivers are allowed to turn right on red unless a sign specifically prohibits it. This is governed by Colorado Revised Statute 42-4-604, which requires drivers to come to a complete stop and yield to pedestrians and other traffic before making the turn.
- Red Arrow Exception: However, if a red arrow is displayed, drivers must wait for the arrow to turn green before turning. This is a critical distinction, as running a red arrow can result in a significant fine and points on the driver’s license.
Potential Changes
- Denver Considerations: There is a growing movement to ban right turns on red in Denver, driven by safety concerns for pedestrians and cyclists. A transition committee for Mayor Mike Johnston has recommended banning the practice citywide, aligning with Denver’s Vision Zero plan to reduce traffic fatalities.
- National Trends: Other cities across the U.S., such as Chicago, Seattle, and Washington D.C., are also considering or have implemented bans on right turns on red. These changes are part of broader efforts to enhance pedestrian safety and reduce accidents.
Safety Considerations
- Pedestrian and Cyclist Safety: The primary concern with allowing right turns on red is the increased risk of accidents involving pedestrians and cyclists. Studies have shown that right turns on red can lead to a significant increase in such incidents.
- Driver Responsibility: Drivers are expected to exercise caution and yield to vulnerable road users when turning right on red. However, the absence of a requirement to turn right on red means drivers are not obligated to do so if they feel it is unsafe.
While the state-level rule for right turns on red in Colorado remains unchanged, local jurisdictions like Denver may implement changes to enhance safety. Drivers should be aware of local regulations and signs indicating whether right turns on red are allowed or prohibited.
