Lane splitting is one of the most controversial aspects of motorcycle riding. Illegal in nearly every state across the country, lane splitting is a practice of motorcyclists moving through lanes of traffic traveling in the same direction down the center line while other traffic is still in motion. In other words, the motorcyclist essentially makes their own lane in between other vehicles heading in the same direction.
Believe it or not, Colorado recently made some movement on the lane splitting argument, though they technically did not legalize “lane splitting,” but rather, “lane filtering.”
What Is Lane Splitting?
Lane splitting occurs when a motorcyclist rides between two lanes of traffic moving the same way down the road, often when traffic is congested or moving slowly. The practice allows motorcyclists to bypass gridlocked traffic, and it is typically used in urban areas with heavy traffic. However, lane splitting can be dangerous due to the unpredictability of other drivers, sudden lane changes, and other hazards.
Is Lane Splitting Legal in the State of Colorado?
No, lane splitting is not legal in Colorado. According to the Colorado Department of Transportation (CDOT), “passing or overtaking a vehicle in the same lane is illegal,” and there is no allowance for lane sharing or lane splitting between cars and motorcycles. This means that motorcyclists who attempt to lane split in Colorado could be ticketed or fined for violating state traffic laws.
What Is Lane Filtering?
While lane splitting remains illegal in Colorado, the state passed a new law in 2023 allowing lane filtering under certain conditions. Lane filtering happens when a motorcyclist moves between stopped or slow-moving vehicles at intersections or in heavy traffic, but only when the speed of traffic is less than 15 miles per hour. This differs from lane splitting in that it is meant to be done at much lower speeds and in more controlled environments.
The new law allows motorcyclists to filter through lanes of traffic to move ahead at intersections, which can help reduce the risk of rear-end collisions. However, lane filtering is only legal in specific situations, and motorcyclists must still obey all traffic signals and signs.
Risks of Lane Splitting
While some motorcyclists argue that lane splitting increases safety by reducing the chances of being rear-ended, the practice can be dangerous, particularly in states where drivers are not accustomed to motorcycles weaving between lanes. Some common risks associated with lane splitting include:
- Sudden lane changes. Drivers may change lanes without signaling, making it difficult for motorcyclists to anticipate their movements.
- Opening car doors. Passengers in stopped vehicles may unexpectedly open their doors, creating a hazard for motorcyclists.
- Limited visibility. Motorcycles are smaller and less visible than cars, making it harder for drivers to see them approaching in between lanes.
The Debate Over Lane Splitting
There has been considerable debate about the safety of lane splitting. A study conducted by U.C. Berkeley found that lane splitting can increase motorcyclist safety by reducing the chances of a rear-end collision in stop-and-go traffic. However, the study emphasized that lane splitting should only be done at lower speeds (below 50 mph) and when motorcyclists are traveling no more than 15 mph faster than the surrounding traffic.
Despite these findings, the debate over lane splitting continues. Advocates argue that it can reduce traffic congestion and improve motorcyclist safety, while opponents cite concerns over the unpredictability of drivers and the higher risk of accidents.
Penalties for Lane Splitting in Colorado
Since lane splitting is illegal in Colorado, motorcyclists who are caught engaging in this practice could face penalties. This may include fines, citations for reckless driving, and potential points on the driver’s license. More serious penalties may be imposed if lane splitting leads to an accident or injury.
