Understanding Motorcycle Lane Splitting in California

Motorcycle lane splitting, the practice of riding a motorcycle between lanes of slow or stopped traffic, has been a topic of much debate among motorists, motorcyclists, and legislators. In California, it’s not only a common sight but also a legal maneuver under specific conditions. This article delves into the legalities, safety aspects, and the relevant California Vehicle Codes (CVC) governing lane splitting.

The Legal Landscape

California is the first and only state in the United States to explicitly legalize lane splitting. The practice was formally recognized by the state legislature in 2016 with the passage of Assembly Bill 51, which added Section 21658.1 to the California Vehicle Code. This section empowers the California Highway Patrol (CHP) to develop educational guidelines relating to lane splitting in a manner that would ensure the safety of both motorcyclists and other motorists.

Key California Vehicle Codes

1. CVC § 21658.1: Lane Splitting Definitions and Authorization
   • This section defines lane splitting and authorizes the CHP to develop guidelines.
   • “The department may develop educational guidelines relating to lane splitting in a manner that would ensure the safety of the motorcyclist and the drivers and passengers of the surrounding vehicles.”
2. CVC § 21658: Laned Roadways
   • While not specific to lane splitting, this section requires that a vehicle must be driven entirely within a single lane and should not move from the lane until it is safe to do so.
   • “A vehicle shall be driven as nearly as practical entirely within a single lane and shall not be moved from the lane until such movement can be made with reasonable safety.”
3. CVC § 22350: Basic Speed Law
   • This code stipulates that no person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent, having due regard for weather, visibility, the traffic on, and the surface and width of, the highway, and in no event at a speed which endangers the safety of persons or property.
   • This law applies to motorcyclists while lane splitting, emphasizing the need to split lanes at a safe speed.

CHP Lane Splitting Guidelines

The CHP guidelines, developed in response to CVC § 21658.1, provide crucial insights into how motorcyclists can safely practice lane splitting:

1. Speed Differential: Motorcyclists should not exceed the speed of traffic by more than 10 mph.
2. Overall Speed: Lane splitting should not be performed at speeds exceeding 30 mph.
3. Environment Awareness: Lane splitting is safer when traffic is moving at 30 mph or less.
4. Roadway Conditions: Motorcyclists should consider the total environment, including the width of the lanes, the size of surrounding vehicles, and roadway conditions.

Safety Considerations

While lane splitting can offer advantages such as reduced traffic congestion and decreased travel time for motorcyclists, it comes with inherent risks. The following safety tips are essential for motorcyclists:

1. Visibility: Motorcyclists should ensure they are visible to other drivers. Wearing bright or reflective gear and using proper lighting is crucial.
2. Awareness: Constant vigilance is necessary. Motorcyclists must be aware of their surroundings, including the behavior of other drivers who may change lanes unexpectedly.
3. Condition of the Bike: Regular maintenance checks, especially on brakes and tires, are vital to ensure the motorcycle is in optimal condition for maneuvering between lanes.

Conclusion

Motorcycle lane splitting in California is a legally sanctioned practice that, when performed within the guidelines, can be a safe and efficient way for motorcyclists to navigate through traffic. Understanding and adhering to the California Vehicle Codes and CHP guidelines is essential for ensuring the safety of all road users. By being informed and cautious, motorcyclists can take advantage of lane splitting to improve their riding experience while minimizing risks.  If you or a loved one have been injured on a motorcycle in California, call us toll free 24/7 at 866-966-5240 or visit our motorcycle accident information page.
