Colorado cyclists are responsible to follow the same rules and regulations as motor vehicles, which includes yielding to pedestrians, using lights between sunset and sunrise, and obeying all traffic signs and signals. (CRS 42-4-1412) However, there are additional rules that apply to cyclists when riding on public roadways:
- Cyclists must ride as close to the curb as possible – either in a designated bicycle lane, on a paved shoulder or in the right-hand lane. Unless:
- when passing another bicycle or vehicle proceeding in the same direction
- when preparing to make a left turn
- when proceeding straight through an intersection where the traffic is turning right
- when reasonably necessary to avoid hazardous conditions, including fixed or moving objects, parked or moving vehicles, pedestrians, animals, or surface hazards such as potholes or debris
- No bicycle shall be used to carry more persons at one time than the number for which it is designed or equipped.
- No cyclist shall attach themselves or their bicycle to any motor vehicle.
- Cyclists may ride abreast if there is no motor vehicle traffic approaching from the rear within a distance of three hundred feet, they are able to fit within one single lane, or they are riding on a path or roadway set aside for the exclusive use of bicycles. Otherwise, cyclists must ride single file.
- The cyclist must keep at least one hand on the handlebars at all times.
- Cyclists must use hand signals for 100 feet in advance of a turn unless you need both hands to brake or control your bicycle.
Please refer to the official Colorado Revised Statutes for more details.
For those who may be riding trails instead of public roadways, there are trail-specific guidelines to follow:
- Plan ahead –carry necessary supplies for changes in the weather, and know your equipment, your ability, and the area in which you will be riding.
- Yield appropriately – bicyclists should yield to other non-motorized trail users. Bicyclists traveling downhill should always yield to those heading uphill unless the trail is clearly signed for one-way or downhill-only traffic.
- Respect trail and road closures - do not trespass on private land, and obtain permits as required.
- Leave no trace – stay on existing trails and do not create new ones. Don’t cut switchbacks, and do not leave any trash of any kind on the trail.
- Control your bicycle – obey speed regulations and recommendations and ride within your limits.
- Respect wildlife – give animals enough room and time to adjust to you and avoid sudden movements and loud noises.
eBikes are becoming more and more popular in Colorado. Local governments have final say in where eBikes can be ridden. Typically, they are allowed on roads and have the same rights and responsibilities as non-electric bicycles.
- In most cities in Colorado, eBikes are not permitted to be ridden using the electric-assist when on paved bike or pedestrian paths.
- All 42 Colorado state parks allow eBikes on mountain bike paths, but rules for city and county trails vary throughout the state. On these paths, eBikes are expected to follow the same rules as mountain bikes (see above.)
- On Federal lands, eBikes are considered motorized vehicles and are generally only permitted on trails that allow ATVs, motorbikes, etc.
With such a variety of rules and regulations for eBikes, it is best practice to always check with the governing agency on eBike rules prior to riding.
In most cases, it is illegal for cyclists to ride on the sidewalk and are expected to ride with traffic, not against it – so as someone driving a motor vehicle, please be courteous, share the road, and obey all traffic laws, signs, and signals. When passing a bicyclist, allow at least three feet of space between your car and the cyclist.
With so many motor vehicles and bicycles sharing the road, these laws strive to help bicyclists avoid motor vehicle collisions. Although Colorado may not currently have a law that requires bicyclists to wear helmets, it is the number one piece of safety advice we can provide to cyclists – please always wear a helmet, ride safely, and follow all Colorado rules and regulations.
