It is the intent of the general assembly that nothing contained in House Bill No. 1246, enacted at the second regular session of the fifty-sixth general assembly, shall in any way be construed to modify or increase the duty of the department of transportation or any political subdivision to sign or maintain highways or sidewalks or to affect or increase the liability of the state of Colorado or any political subdivision under the “Colorado Governmental Immunity Act”, article 10 of title 24, C.R.S.

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.       Upon approaching an intersection where right turns are permitted and there is a dedicated right-turn lane, a bicyclist may ride on the left-hand portion of the dedicated right-turn lane even if the bicyclist does not intend to turn right.       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.       A person operating a bicycle, electrical assisted bicycle, or electric scooter upon a one-way roadway with two or more marked traffic lanes may ride as near to the left-hand curb or edge of the roadway as judged safe by the rider, subject to the following conditions:   If the left-hand lane then available for traffic is wide enough to be safely shared with overtaking vehicles, a bicyclist shall ride far enough to the left as judged safe by the bicyclist to facilitate the movement of such overtaking vehicles unless other conditions make it unsafe to do so.

After proceeding across the intersecting roadway to the far corner of the curb or intersection of the roadway edges, the rider shall stop, as much as practicable, out of the way of traffic. After stopping, the rider shall yield to any traffic proceeding in either direction along the roadway that the rider had been using. After yielding and complying with any official traffic control device or police officer regulating traffic on the highway along which the rider intends to proceed, the rider may proceed in the new direction.    Notwithstanding the provisions of paragraphs (a) and (b) of this subsection (8), the transportation commission and local authorities in their respective jurisdictions may cause official traffic control devices to be placed on roadways and thereby require and direct that a specific course be traveled.         Except as otherwise provided in this subsection (9), every person riding a bicycle, electrical assisted bicycle, or electric scooter shall signal the intention to turn or stop in accordance with section 42-4-903; except that a person riding a bicycle, electrical assisted bicycle, or electric scooter may signal a right turn with the right arm extended horizontally.
