Ride Smart Drive Smart: Rules of the Road#
Ride Smart Drive Smart is an education, enforcement and encouragement initiative developed by FC Bikes in partnership with Fort Collins Police Services. The initiative is designed to educate both cyclists and motorists how to safely and lawfully share the roadways, encourage smart riding and driving behavior and enforce laws for safety.
Check out the tips in our downloadable Ride Smart Drive Smart brochure (link to brochure) and see more tips below. Also look for the Ride Smart Drive Smart van around town where we will be doing field education and events. Learn more ways to Ride Smart and Drive Smart in our bicycling classes (link to classes page) offered year-round.
Colorado State Bicycle Laws#
All laws mentioned below were current as of August 2012 and may be subject to change.
Safe Passing Laws#
Colorado has codified a three foot passing requirement in three rules to address the variety of circumstances in which a bicyclist may be overtaken by a motorist. These circumstances are:
- Passing oncoming vehicles
- Passing to the left
- Passing to the right
In each case the motorist must maintain at least a three foot distance between the side of their vehicle facing the bicyclist, including all mirrors or other projections, and the bicyclist being overtaken.

Colorado has no helmet law. It is legal for all persons of any age to operate a bicycle without wearing a helmet unless otherwise provided by a municipal regulation.
Share the Road license plates#
Colorado, in conjunction with Bicycle Colorado, offers Share the Road license plates. For more information on such plates please visit: https://www.bicyclecolorado.org/get-involved/share-the-road/

Vulnerable Road User Laws#
Colorado does not define who is a "vulnerable road user," but has several statutes aimed at protecting bicyclists specifically. These include:
- Any person who knowingly projects any object or substance at or against a bicyclist commits a class 2 misdemeanor.
- Any driver of a motor vehicle who, in a careless and imprudent manner, drives the vehicle unnecessarily close to, toward, or near a bicyclist is guilty of the offense of careless driving, which is a class 2 misdemeanor traffic offense. If the careless driving results in serious injury or death then it is a class 1 misdemeanor traffic offense.

Where to Ride#
Colorado has some of the most specific laws regarding where a bicyclist should ride, and just as importantly, where a bicyclist should not be obligated to ride in the nation. The general rule is that:
If the right-hand lane then available for traffic is wide enough to be safely shared with overtaking vehicles, a bicyclist shall ride far enough to the right as judged safe by the bicyclist to facilitate the movement of such overtaking vehicles unless other conditions make it unsafe to do so. A bicyclist may use a lane other than the right-hand lane when:
- Preparing for a left turn at an intersection or into a private roadway or driveway;
- Overtaking a slower vehicle; or
- Taking reasonably necessary precautions to avoid hazards or road conditions.
A bicyclist shall not be expected or required to:
- Ride over or through hazards at the edge of a roadway, including but not limited to fixed or moving objects, parked or moving vehicles, bicycles, pedestrians, animals, surface hazards, or narrow lanes; or
- Ride without a reasonable safety margin on the right-hand side of the roadway.

Colorado provides that no person shall drive any vehicle other than a bicycle, electric assisted bicycle, or any other human-powered vehicle upon a sidewalk or sidewalk area, except upon a permanent or duly authorized temporary driveway.
In addition, when a person is riding a bicycle upon a sidewalk, pathway or crosswalk the bicyclist shall:
- Yield the right-of-way to any pedestrian and shall give an audible signal before overtaking and passing such pedestrian in a manner that is safe for pedestrians.
- Not ride a bicycle where such use is prohibited by official traffic control devices or local ordinances. A person riding a bicycle shall dismount before entering any crosswalk where required by official traffic control devices or local ordinances.
- Have all the rights and duties applicable to a pedestrian under the same circumstances.

Mandatory Use of Separated Facilities#
Colorado does not require that bicyclists use any lane or path other than a normal vehicular traffic lane.
Bicycling Under the Influence#
In Colorado, bicycles are defined as vehicles. Colorado's law prohibiting driving while under the influence of alcohol or other controlled substances is written so that it applies to all vehicles and therefore applies to bicyclists. Bicycles should not be operated while intoxicated and operating a bicycle while under the influence of alcohol or other controlled substances may result in severe punishments.

Authorization for Local Regulation of Bicycles#
Colorado provides that its traffic laws shall not be deemed to prevent local authorities, with respect to streets and highways under their jurisdiction and within the reasonable exercise of the police power, except those streets and highways that are parts of the state highway system, from regulating the operation of bicycles and requiring the registration and licensing of same, including the requirement of a registration fee, consistent with state traffic laws.

Colorado requires that no person open the door of a motor vehicle on the side available to moving traffic unless and until it is reasonably safe to do so and can be done without interfering with the movement of other traffic. In addition, no person shall leave a door open on the side of a vehicle available to moving traffic for a period of time longer than necessary to load or unload passengers.

Treatment as a Vehicle#
In Colorado bicycles are vehicles according to the statute that defines vehicles and a person riding a bicycle has all of the rights and duties of the driver of a vehicle as provided in Article 42-4.
