The Colorado Safety Stop is the law of the land

Earlier today, on April 13, 2022, Governor Jared Polis signed the Colorado Safety Stop into law. That means bicyclists like you have a new safe and legal option to proceed through intersections across the state. 

This new law means that when an intersection is clear and they already have the right of way, bicyclists ages 15 and older may now treat stop signs as yield signs and treat stop lights as stop signs.

Additional details of the law include:

  • Younger bicyclists may perform the maneuver if an adult is present.
    Bicyclists can yield and then proceed through stop sign-controlled intersections at up to 10 miles per hour.
  • Intersections where bicyclist-specific lights or signs are present that prohibit the maneuver are exempt from the new law.
  • The bill defines “low speed conveyances” in Colorado law. These are small profile, low-speed vehicles that people use for transportation and recreation, including bicycles and electric bicycles, electric scooters (not including mopeds), and wheelchairs.

This has been an effort years in the making and all of us at Bicycle Colorado are immensely proud to cross the finish line on this safety-enhancing policy and call the Colorado Safety Stop the law of the land. The data is clear: this prevents crashes between bicyclists and drivers where they happen the most—intersections—and that’s why we’ve fought so hard for this to become statewide policy for so many years.

We owe a huge debt of gratitude to our bill sponsors in 2022 who championed the Colorado Safety Stop in the legislature, and especially the bill’s prime sponsors: Representatives Matt Gray (D-33) and Edie Hooton (D-10) and Senators Faith Winter (D-24) and Kevin Priola (R-25).

We are also grateful to Governor Jared Polis for signing the bill and recognizing the importance of providing safe and legal options for people who choose to or need to travel by bike.

1. When does this new law take effect? 2. Are bike path stop signs considered a bicycle specific sign that would prohibit “stop as yield”?

    Jack Todd - Reply

    Hi Greg! The law took effect immediately upon the Governor’s signature. And no, bike path stop signs are not considered bicycle-specific.

    Intersections where bicyclist-specific lights or signs are present that prohibit the maneuver are exempt from the new law.

Is there going to be a PR campaign to let drivers and cyclists both know about this law change? A know a lot of grumpy drivers that are always complaining about cyclists doing this; it would be good to let them know it’s legal for us to do this now!

    Aishwarya Krishnamoorthy - Reply

    Thanks for asking, Alex! We’ll be partnering with the Colorado Department of Transportation to get the word out around the state, in schools and elsewhere. In addition to our own outreach to local partners, police departments and organizations, we’re also going to be working with the Colorado Municipal League to get the word out to communities across the state—they represent all the municipalities and local governments statewide, and typically do a tour of the state to share pertinent information on important changes after each legislative session.
    We’ll also be incorporating this into our Bicycle-Friendly Driver and upcoming digitized educational program called SHIFT Driving(TM), both of which aim to bridge education gaps for more experienced drivers or drivers who haven’t recently taken a driving test.

What does this look like for towns that specifically have laws in the books on cyclists having to stop at stop signs? Will this overrule their “home rule”?

    Jack Todd - Reply

    Home rule communities can still implement more specific regulations, just like with any other law.

Doug - Reply

Please tell me this law doesn’t include a flaggers stop sign. If it does I’m still instructing my flaggers to stop all bikes.

    Jack Todd - Reply

    Hi Doug, good question. That is not the intent of the law. Bicyclists may proceed only when they have the right of way, and I believe your flaggers will have the discretion to determine whether that is the case in a construction zone.

I am a little confused about the “treat stop lights as stop signs” portion of the law. Does it mean that if I stop at a red light, where there are cars already stopped, I can proceed through the intersection before the light turns green?

    Jack Todd - Reply

    That’s right, Bob. If there is no oncoming cross traffic and you have the right-of-way, you’d be able to choose to proceed through the intersection while the light is still red after coming to a complete stop.

Are there any ideas regarding gathering information on cities/counties that may have local rules that override the state?
It may be useful to be able to go to a web page that tries to keep an updated list, but I realize that would be a huge undertaking.

Jody - Reply

I’d like to see how-to videos of all of these different scenarios that instruct the cyclists and the drivers of cars on what these situations may look like.

Paul West - Reply

I don’t understand the right of way condition. How does a bicyclist have the right of way when stopped at a red light?

Is a bicyclist actually able to proceed at low speed through a all-way stop if another vehicle has arrived at the intersection from the left at the same time, but not if it arrives from the right? Wouldn’t the simultaneous arrival of another vehicle essentially mean that the intersection isn’t clear regardless of the direction of travel?

I’d sure like to be able to bike safely under the new law, but I don’t feel confident that I understand the new regulation.

    Jack Todd - Reply

    Hi Paul, good questions. Regarding red lights, the law says that a bicyclist approaching a red light “shall stop before entering the intersection and shall yield to all other traffic and pedestrians. Once the [bicyclist] has yielded, the [bicyclist] may cautiously proceed.” Rather than thinking of it in terms of the “right-of-way” at red lights, it’s helpful to think of it as “when the coast is clear.”

    At stop signs, typical teaching is to “yield to the right” when it comes to the right of way. So if a driver or another bicyclist shows up at the same time as you to your right, that person has the right-of-way. If a driver or another bicyclist shows up at the same time as you to your left, you have the right of way. Of course, we always advise you make the choice that feels safest to you.

I read the act, and I would like a little clarification regarding left turns at intersections with a stop light. The way I read the act, bicycles are no longer allowed to make left turns onto any two way street that are controlled by stop lights rather than stop signs. Am I reading this right?

    Jack Todd - Reply

    Hi Lucas, this is correct when at a red light and planning to turn left. This was included in the bill because in the event that there is traffic on the opposite side of a red light, a bicyclist may not be aware of an “opposing signal” — a green light that opposing traffic may have. Bicyclists would then be at risk of a broadside crash if they were to take a left turn.

      Lucas Currell - Reply

      Thank you Jack for your clarification. I understand exactly what you are saying about the opposing green light not being visible to the cyclist. There is an intersection on my normal commuting route to work that is a perfect example of the scenario you described. I do have one more question about this though. If the cyclist has merged into traffic, and is no longer in the bike lane, but in the left turn lane just like a car, can the bicyclist turn left onto a two way street if they wait for the light to turn green? Is that permissible? I understand why the cyclist can’t treat the stop light like a stop sign when it comes to left turns.

Is there any guidance on how this might apply to low-powered mopeds and motor scooters? I ride a 50cc scooter.

    Jack Todd - Reply

    Hi Dustin, this does not apply to low-powered mopeds or motor scooters. The rules of motor vehicles still apply in that case. Good question!

What in the world? I’m super confused at how this makes navigating an intersection safer for cyclists’. What happens when a car is going way to fast through an intersection on a green (or yellow) or runs a stop sign (which happens all the time) and the cyclist misjudges and is at 10mph or less? This very intentionally puts them in the intersection with cross traffic??? I have an open mind and am willing to hear out the argument… but as a law enforcement officer… I’ve seen WAY TOO MANY bicycle involved accidents at intersections and can’t figure how this would help. Either way… it’s now the law (if I agree with it or not) and will be enforced as such… Just praying that it doesn’t hurt even more cyclists passing through.

    Jack Todd - Reply

    Hi Jason, this law allows bicyclists to treat stop signs as yield signs and stop lights as stop signs, so bicyclists must come to a complete stop before crossing on a red light. Intersections are by far the most dangerous locations for bicyclists to be riding, with nearly 3/4 of crashes between bicyclists and drivers occurring there. Getting bicyclists out of the intersection faster has proven elsewhere to reduce those same crashes. Idaho saw a nearly 15% reduction in crashes between bicyclists and drivers in the year after they adopted this, and Delaware saw a 23% drop in those same crashes in the 30 months after adopting the bill compared to before adopting it. We’ve seen elsewhere that this makes intersections safer for bicyclists, and that’s why we worked so hard to pass it.
