Notwithstanding any contrary provision in this article 4, when a county or municipality has adopted an ordinance or resolution pursuant to section 42-4-1412.5, riders are subject to the local ordinance or resolution.
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.
No bicycle or electrical assisted bicycle shall be used to carry more persons at one time than the number for which it is designed or equipped.
No person riding upon any bicycle or electrical assisted bicycle shall attach the same or himself or herself to any motor vehicle upon a roadway.

Any person operating a bicycle or an electrical assisted bicycle upon a roadway at less than the normal speed of traffic shall ride in the right-hand lane, subject to the following conditions:

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.

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 or an electrical assisted bicycle upon a one-way roadway with two or more marked traffic lanes may ride as near to the left-hand curb or edge of such roadway as judged safe by the bicyclist, 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.
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 left-hand side of the roadway.

Persons riding bicycles or electrical assisted bicycles upon a roadway shall not ride more than two abreast except on paths or parts of roadways set aside for the exclusive use of bicycles.

A person riding a bicycle or electrical assisted bicycle intending to turn left shall approach the turn as closely as practicable to the right-hand curb or edge of the roadway. After proceeding across the intersecting roadway to the far corner of the curb or intersection of the roadway edges, the bicyclist shall stop, as much as practicable, out of the way of traffic. After stopping, the bicyclist shall yield to any traffic proceeding in either direction along the roadway that the bicyclist had been using. After yielding and complying with any official traffic control device or police officer regulating traffic on the highway along which the bicyclist intends to proceed, the bicyclist 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.

1. Except as otherwise provided in this subsection (9), every person riding a bicycle or electrical assisted bicycle shall signal the intention to turn or stop in accordance with section 42-4-903; except that a person riding a bicycle or electrical assisted bicycle may signal a right turn with the right arm extended horizontally.
2. A signal of intention to turn right or left when required shall be given continuously during not less than the last one hundred feet traveled by the bicycle or electrical assisted bicycle before turning and shall be given while the bicycle or electrical assisted bicycle is stopped waiting to turn.

The "Colorado Safety Stop" is now the law statewide! This safe and common-sense approach clears intersections more efficiently, thus keeping cyclists safer

§ 42-4-1412.5. Statewide regulation of certain persons approaching intersections who are not operating motor vehicles--status of existing local ordinance or resolution--legislative declaration--definitions

The general assembly hereby finds and declares that:

The regulation of persons approaching controlled intersections is a matter of mixed state and local concern; and
It is necessary, appropriate, and in the best interest of the state to reduce injuries, fatalities, and property damage resulting from collisions at controlled intersections between motor vehicles and persons who are not operating motor vehicles by allowing most persons approaching controlled intersections who are fifteen years of age or older or who are under fifteen years of age and accompanied by an adult and who are not operating motor vehicles to approach controlled intersections in the manner set forth in this section.

1. (I) A pedestrian or a person who is fifteen years of age or older or who is under fifteen years of age and accompanied by an adult and who is operating a low-speed conveyance and approaching a controlled intersection with a stop sign shall slow down and, if required for safety, stop before entering the intersection. If a stop is not required for safety, the pedestrian or person operating a low-speed conveyance shall slow to a reasonable speed and yield the right-of-way to any traffic or pedestrian in or approaching the intersection. After the pedestrian or person operating a low-speed conveyance has slowed to a reasonable speed and yielded the right-of-way if required, the pedestrian or person operating a low-speed conveyance may cautiously make a turn or proceed through the intersection without stopping.
  (II) For purposes of this subsection (2)(a), a reasonable speed is ten miles per hour or less. A municipality, by ordinance, or a county, by resolution, may raise the maximum reasonable speed to twenty miles per hour if the municipality or county also posts signs at the intersection stating that higher speed limitation.
2. A person who is fifteen years of age or older or who is under fifteen years of age and is accompanied by an adult and who is operating a low-speed conveyance and approaching a controlled intersection with an illuminated red traffic control signal shall stop before entering the intersection and shall yield to all other traffic and pedestrians. Once the person operating a low-speed conveyance has yielded, the person operating a low-speed conveyance may cautiously proceed in the same direction through the intersection or make a right-hand turn. When a red traffic control signal is illuminated, a person operating a low-speed conveyance shall not proceed through the intersection or turn right if an oncoming vehicle is turning or preparing to turn left in front of the person operating a low-speed conveyance.
3. A person who is fifteen years of age or older or who is under fifteen years of age and is accompanied by an adult and who is operating a low-speed conveyance approaching an intersection of a roadway with an illuminated red traffic control signal may make a left-hand turn only if turning onto a one-way street and only after stopping and yielding to other traffic and pedestrians. However, a person operating a low-speed conveyance shall not turn left if an oncoming vehicle is turning or preparing to turn right.
4. Notwithstanding any other provision of this subsection (2), if a county or municipality has placed a traffic sign or a traffic control signal at a controlled intersection and the traffic sign or traffic control signal provides instructions only to one or more specified types of low-speed conveyances, the operator of a low-speed conveyance to which the traffic sign or traffic control signal is directed shall obey the instructions provided by the sign or traffic control signal.
5. If a county or municipality adopted a valid ordinance or resolution that regulates bicycles or electrical assisted bicycles substantially as described in subsections (2)(a.5), (2)(b.5), and (2)(c.5) of this section prior to May 3, 2018, that ordinance or resolution remains valid to the extent that it applies to the operation of bicycles or electrical assisted bicycles by persons who are under fifteen years of age and who are not accompanied by an adult.
(2.5) This section supersedes any conflicting ordinance that a municipality, county, or city and county adopts, but nothing in this section affects the validity of any ordinance or resolution adopted by a municipality, county, or city and county that regulates the conduct of persons approaching controlled intersections and does not conflict with this section.
This section does not diminish or alter the authority of the department of transportation or the state transportation commission, as those entities are defined in section 43-1-102, regarding the department’s or commission’s authority to regulate motor vehicle traffic on any portion of the state highway system as defined in section 43-2-101(1).

(3.5) This section does not create any right for a pedestrian or the operator of a low-speed conveyance to travel on any portion of a roadway where travel is otherwise prohibited by state law or by an ordinance or resolution adopted by a municipality, county, or city and county.
As used in this section:

"Controlled intersection" means an intersection of a roadway that is controlled by either a stop sign or a traffic control signal.
"Low-speed conveyance" means:

(I) A vehicle, as defined in section 42-1-102(112), that is not a motor vehicle, as defined in section 42-1-102(58), a low-power scooter as defined in section 42-1-102(48.5), or a low-speed electric vehicle, as defined in section 42-1-102(48.6);
(II) A toy vehicle, as defined in section 42-1-102(103.5), that is exclusively human-powered; or
(III) An electric personal assistance mobility device or EPAMD, as defined in section 42-1-102(28.7), or a device that would be an electric personal assistance mobility device or EPAMD but for the fact that it has fewer or more than two wheels or has tandem wheels.

I have always thought that three feet was the minimum safe distance for a motor vehicle driver to give a cyclist when passing. Fortunately for cyclists, in Colorado its the law!

§ 42-4-1003. Overtaking a vehicle on the left

The following rules shall govern the overtaking and passing of vehicles proceeding in the same direction, subject to the limitations, exceptions, and special rules stated in this section and sections 42-4-1004 to 42-4-1008:

The driver of a vehicle overtaking another vehicle proceeding in the same direction shall pass to the left of the vehicle at a safe distance and shall not again drive to the right side of the roadway until safely clear of the overtaken vehicle
The driver of a motor vehicle overtaking a bicyclist proceeding in the same direction shall allow the bicyclist at least a three-foot separation between the right side of the driver's vehicle, including all mirrors or other projections, and the left side of the bicyclist at all times.
Except when overtaking and passing on the right is permitted, the driver of an overtaken vehicle shall give way to the right in favor of the overtaking vehicle on audible signal and shall not increase the speed of the driver's vehicle until completely passed by the overtaking vehicle.

Any person who violates any provision of this section commits a class A traffic infraction.

If you ride between sunset and sunrise, both safety considerations and the law require the following:

§ 42-4-204. When lighted lamps are required

Every vehicle upon a highway within this state, between sunset and sunrise and at any other time when, due to insufficient light or unfavorable atmospheric conditions, persons and vehicles on the highway are not clearly discernible at a distance of one thousand feet ahead, shall display lighted lamps and illuminating devices as required by this article for different classes of vehicles, subject to exceptions with respect to parked vehicles.
Whenever requirement is declared by this article as to distance from which certain lamps and devices shall render objects visible or within which such lamps or devices shall be visible, said provisions shall apply during the times stated in subsection (1) of this section in respect to a vehicle without load when upon a straight, level, unlighted highway under normal atmospheric conditions, unless a different time or condition is expressly stated.
Whenever requirement is declared by this article as to the mounted height of lamps or devices, it shall mean from the center of such lamp or device to the level ground upon which the vehicle stands when such vehicle is without a load.
Any person who violates any provision of this section commits a class A traffic infraction.

And the following is what the law requires for lights and reflectors - it might surprise you!

§ 42-4-221. Bicycle and personal mobility device equipment

No other provision of this part 2 and no provision of part 3 of this article shall apply to a bicycle, electrical assisted bicycle, or EPAMD or to equipment for use on a bicycle, electrical assisted bicycle, or EPAMD except those provisions in this article made specifically applicable to such a vehicle.
Every bicycle, electrical assisted bicycle, or EPAMD in use at the times described in section 42-4-204 shall be equipped with a lamp on the front emitting a white light visible from a distance of at least five hundred feet to the front.
Every bicycle, electrical assisted bicycle, or EPAMD shall be equipped with a red reflector of a type approved by the department, which shall be visible for six hundred feet to the rear when directly in front of lawful lower beams of head lamps on a motor vehicle.
Every bicycle, electrical assisted bicycle, or EPAMD when in use at the times described in section 42-4-204 shall be equipped with reflective material of sufficient size and reflectivity to be visible from both sides for six hundred feet when directly in front of lawful lower beams of head lamps on a motor vehicle or, in lieu of such reflective material, with a lighted lamp visible from both sides from a distance of at least five hundred feet.
A bicycle, electrical assisted bicycle, or EPAMD or its rider may be equipped with lights or reflectors in addition to those required by subsections (2) to (4) of this section.
A bicycle or electrical assisted bicycle shall not be equipped with, nor shall any person use upon a bicycle or electrical assisted bicycle, any siren or whistle.
Every bicycle or electrical assisted bicycle shall be equipped with a brake or brakes that will enable its rider to stop the bicycle or electrical assisted bicycle within twenty-five feet from a speed of ten miles per hour on dry, level, clean pavement.
A person engaged in the business of selling bicycles or electrical assisted bicycles at retail shall not sell any bicycle or electrical assisted bicycle unless the bicycle or electrical assisted bicycle has an identifying number permanently stamped or cast on its frame.
Any person who violates any provision of this section commits a class B traffic infraction.

If you are riding where it is permissible to ride on the sidewalk, and are crossing at a crosswalk, the following statute applies:

§ 42-4-802. Pedestrians' right-of-way in crosswalks

When traffic control signals are not in place or not in operation, the driver of a vehicle shall yield the right-of-way, slowing down or stopping if need be to so yield, to a pedestrian crossing the roadway within a crosswalk when the pedestrian is upon the half of the roadway upon which the vehicle is traveling or when the pedestrian is approaching so closely from the opposite half of the roadway as to be in danger.
No pedestrian shall suddenly leave a curb or other place of safety and ride a bicycle, ride an electrical assisted bicycle, walk, or run into the path of a moving vehicle that is so close as to constitute an immediate hazard.

State Statutes can be superseded by municipal ordinances when it comes to bicycles. It is important to know the ordinances of the community in which you live or ride. Urge your local law makers to simply conform to state statute on issues relating to bicycles!

§ 42-4-111. Powers of local authorities

This article 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 that are subject to section 43-2-135, C.R.S., from:
(h) Regulating the operation of bicycles or electrical assisted bicycles and requiring the registration and licensing of same, including the requirement of a registration fee, consistent with the provisions of this article;

In Colorado, the driver of a vehicle may pass a bicyclist in what would otherwise be a no passing zone if it can be done safely to all other road users. The specific statutory language can be found here:

§ 42-4-1005. Limitations on overtaking on the left

No vehicle shall be driven to the left side of the center of the roadway in overtaking and passing another vehicle proceeding in the same direction unless authorized by the provisions of this article and unless such left side is clearly visible and is free of oncoming traffic for a sufficient distance ahead to permit such overtaking and passing to be completed without interfering with the operation of any vehicle approaching from the opposite direction or any vehicle overtaken. In every event the overtaking vehicle must return to an authorized lane of travel as soon as practicable and, in the event the passing movement involves the use of a lane authorized for vehicles approaching from the opposite direction, before coming within two hundred feet of any approaching vehicle.
No vehicle shall be driven on the left side of the roadway under the following conditions:

When approaching or upon the crest of a grade or a curve in the highway where the driver's view is obstructed within such distance as to create a hazard in the event another vehicle might approach from the opposite direction;
When approaching within one hundred feet of or traversing any intersection or railroad grade crossing; or
When the view is obstructed upon approaching within one hundred feet of any bridge, viaduct, or tunnel.

The department of transportation and local authorities are authorized to determine those portions of any highway under their respective jurisdictions where overtaking and passing or driving on the left side of the roadway would be especially hazardous and may by appropriate signs or markings on the roadway indicate the beginning and end of such zones. Where such signs or markings are in place to define a no-passing zone and such signs or markings are clearly visible to an ordinarily observant person, no driver shall drive on the left side of the roadway within such no-passing zone or on the left side of any pavement striping designed to mark such no-passing zone throughout its length.
The provisions of this section shall not apply:
…..

d. To the driver of a vehicle passing a bicyclist moving the same direction and in the same lane when such movement can be made in safety and without interfering with, impeding, or endangering other traffic lawfully using the highway.

"Rolling Coal" is not only obnoxious and unsafe, but it is now illegal in Colorado.
