The Colorado Safety Stop is a state law that allows people on bicycles and other low-speed vehicles (like scooters) to: 

• Slowly roll through stop signs without fully stopping if it's safe to do so.
• Treat red lights as stop signs if there's no oncoming traffic. 

How to use the Colorado Safety Stop 

The Colorado Safety Stop law allows people on bicycles to: 

• At a stop sign: Slowly roll through the stop sign without coming to a complete stop if there is no vehicle or pedestrian traffic present. Bicycle users must still yield to pedestrians and other vehicles present at the stop sign. 
• At a red light: Treat a red light as a stop sign if there is no oncoming traffic. Bicycle users must still yield to pedestrians and other vehicles traveling through the intersection.
• At a bicycle traffic signal: Follow the signals as directed.  

The Colorado Safety Stop doesn’t apply when:

• A sign prohibits it: Some intersections may have signs specifically prohibiting the use of the Colorado Safety Stop. 
• Using it is unsafe: Cyclists must always prioritize safety. If it's not safe to roll through a stop sign or treat a red light as a stop sign, they must stop. 

Who can use the Colorado Safety Stop
People ages 15 and up – or younger people accompanied by a parent or legal guardian – using a bicycle or other low-speed vehicle can use the Colorado Safety Stop. 

Other requirements
Bike lights are required by law in Colorado. All bicycle users must have working front and rear bike lights during low light conditions and at night.
