Colorado Bicycle Laws

The Bicycle Safety Act was passed in Colorado in 2009 and codified what most people consider common sense. For example:   No hitching rides on moving vehicles; Bikes are not allowed on highways; Form a single line in heavy traffic, and; Keep at least one hand on handlebars at all times. But, did you also know that cyclist are not permitted to wear headphones or earbuds while riding?

For more specifics read the Act. And remember, each State, County and City may have their own specific rules regulating bikes. The primary Colorado statute governing cyclist is C.R.S. § 42-4-1412, some highlights include:

See C.R.S. § 42-4-1412 for more details and follow the transportation food chain - Motorists must yield to cyclists and pedestrians. Cyclists must yield to pedestrians. Remember - If you wouldn’t do it in your car- you probably shouldn’t do it on your bike.
