Can Cyclists Roll Through Stop Signs in Colorado?

Intersections are the most dangerous places for bicyclists. National crash data consistently shows the majority of bike v. vehicle accidents occur where roads meet. For years, cyclists in many states were required to come to a complete stop at every stop sign and red light—even when no other vehicles or pedestrians were present.

But Colorado has a different rule. Thanks to the Colorado Safety Stop Law, cyclists may roll through stop signs under specific conditions. Supporters of the law point to several key benefits:

• Fewer crashes at intersections: Intersections are where most serious bike accidents occur. Allowing cyclists to move through quickly and predictably reduces the chance of conflict with cars.
• Proven success in other states: Studies from Idaho and Delaware show no increase in accidents. In fact, cyclist injuries went down after passage of similar laws.
• Improved traffic flow: Cyclists are not forced to wait through long red lights that often fail to detect their presence.
• Consistency across Colorado: Before 2022, only some Colorado cities allowed the Safety Stop. Now, the law applies statewide.
• Encourages more biking: By aligning traffic rules with real-world riding behavior, the law makes cycling a more practical commuting option.

Colorado’s Safety Stop: How It Works

In April 2022, Governor Jared Polis signed HB 22-1028, creating the statewide “Safety Stop” law. This rule applies to bicycles and other low-speed devices, such as e-bikes, scooters, and skateboards.

Here’s how it works:

• Stop signs as yield signs: Riders 15 and older (or younger when accompanied by an adult) may slow to a “reasonable speed” (no faster than 10 MPH), check for traffic and pedestrians, and continue through the intersection without coming to a complete stop—if it is safe.
• Red lights as stop signs: Cyclists must first come to a full stop at a red light. After yielding to traffic and pedestrians, they may proceed straight or turn right. A left turn onto a one-way street is also allowed, but a left turn onto a two-way street at a red light is not permitted.
• Applies to more than just bikes: The law covers e-bikes, scooters, skateboards, and other “low-speed conveyances.”

Even though HB 22-1028 created a consistent statewide law, cities and towns can still regulate intersections by (1) posting signs prohibiting the Safety Stop at specific locations and (2) lower the allowed “roll-through” speed. And when traffic is heavy, sight lines are blocked, or conditions feel unsafe, the best choice is often to make a full stop. A green light from state law doesn’t override a posted city sign.

What Is the “Idaho Stop” in Colorado?

The “Idaho stop” refers to a traffic law that allows bicyclists to treat stop signs as yield signs and red lights as stop signs. First adopted in Idaho in 1982, the rule recognizes the way most bicyclists naturally ride, improves traffic flow, and has been credited with reducing cyclist injuries at intersections.

Colorado’s new law is modeled on this concept, sometimes referred to as the “Idaho stop in Colorado.” The Idaho stop has inspired many states, including Delaware, Arkansas, Oregon, Utah, North Dakota, Oklahoma, Minnesota, and Washington. The trend reflects growing recognition that bicyclists benefit from rules that account for their unique dynamics and safety needs.

Final Thoughts for Colorado Cyclists

Colorado’s Safety Stop law is a major change in Colorado bicycle laws. It officially permits bicyclists to roll through stop signs under safe conditions and brings the Idaho stop in Colorado into reality. But with this freedom comes responsibility. Cyclists must yield the right of way, remain visible, and prioritize safety over convenience. Motorists, too, should learn about this law so they can share the road more safely with cyclists.
