Intro
Lane splitting, also known as lane sharing or filtering, is a practice where a motorcyclist rides between two lanes of traffic, often to pass slower-moving vehicles or to reduce their travel time. However, the legality of lane splitting varies from state to state, and in Colorado, the laws and regulations surrounding this practice are quite specific.
In Colorado, lane splitting is not explicitly allowed or prohibited by state law. However, there are some rules and guidelines that motorcyclists should be aware of. According to the Colorado Department of Transportation, motorcyclists are allowed to ride in the same lane as other vehicles, but they must follow the same traffic laws and regulations as other drivers.

One of the key concerns with lane splitting is safety. While some motorcyclists argue that lane splitting is a safe and efficient way to navigate through traffic, others argue that it increases the risk of accidents. In Colorado, motorcyclists are required to wear helmets and follow all traffic laws, including speed limits and right-of-way rules.
History of Lane Splitting in Colorado
In recent years, there have been efforts to legalize lane splitting in Colorado. In 2016, a bill was introduced in the Colorado State Legislature that would have allowed motorcyclists to lane split in certain circumstances. However, the bill was ultimately defeated due to concerns about safety.
Despite the lack of explicit legislation, some law enforcement agencies in Colorado have taken a more relaxed approach to lane splitting. For example, the Denver Police Department has stated that they do not actively enforce laws against lane splitting, as long as motorcyclists are riding safely and following traffic laws.
Benefits of Lane Splitting
Proponents of lane splitting argue that it has several benefits, including:
- Reduced traffic congestion: By allowing motorcyclists to ride between lanes, lane splitting can help to reduce traffic congestion and decrease travel times.
- Improved safety: Some motorcyclists argue that lane splitting is safer than traditional lane riding, as it allows them to avoid being rear-ended by other vehicles.
- Increased fuel efficiency: Lane splitting can help motorcyclists to reduce their fuel consumption, as they are able to avoid idling in traffic.
However, these benefits are not universally accepted, and there are also several potential drawbacks to lane splitting.
Risks and Drawbacks of Lane Splitting
Some of the risks and drawbacks of lane splitting include:
- Increased risk of accidents: Lane splitting can increase the risk of accidents, particularly if motorcyclists are not paying attention to their surroundings or if other drivers are not aware of their presence.
- Lack of visibility: Motorcyclists who are lane splitting may be more difficult to see, particularly for drivers who are not expecting to see a motorcycle in their blind spot.
- Inconsistent enforcement: The lack of clear laws and regulations surrounding lane splitting can lead to inconsistent enforcement, which can create confusion and uncertainty for motorcyclists.

Best Practices for Lane Splitting in Colorado

- Avoid lane splitting in heavy traffic or construction zones.
- Follow all traffic laws and regulations, including speed limits and right-of-way rules.
Conclusion
While lane splitting is not explicitly allowed or prohibited in Colorado, motorcyclists should be aware of the potential risks and benefits of this practice. By following best practices and being aware of their surroundings, motorcyclists can minimize their risk of accidents and ensure a safe ride.
