California Lane Splitting Laws Explained: What Every Rider Needs to Know
If you ride a motorcycle in California, you’ve likely heard about lane splitting—riding between lanes of slow or stopped traffic. But is it legal? The short answer: Yes, lane splitting is legal in California. However, there are important rules and safety guidelines every rider should understand to avoid tickets, accidents, and liability issues.
Is Lane Splitting Legal in California?
Yes, California is the only state in the U.S. that has officially legalized lane splitting. This law went into effect in 2017 with the passage of AB 51, which defined lane splitting and gave the California Highway Patrol (CHP) authority to develop safety guidelines.
What Does the Law Say?
According to California Vehicle Code Section 21658.1, lane splitting is defined as “driving a motorcycle, that has two wheels in contact with the ground, between rows of stopped or moving vehicles in the same lane.” While the law allows lane splitting, it does not specify exact speed limits or conditions. Instead, riders are expected to operate safely and prudently.
CHP Lane Splitting Safety Guidelines
The California Highway Patrol recommends the following safety practices:
- Only lane split when traffic is moving at 30 mph or less
- Do not exceed the flow of traffic by more than 10 mph
- Avoid lane splitting near large trucks or buses
- Never lane split in blind spots
- Stay alert for sudden lane changes by other drivers

Why Lane Splitting Is Legal in California
Research shows that lane splitting can reduce traffic congestion and even lower the risk of rear-end collisions for motorcyclists when done safely. However, improper lane splitting remains a major factor in motorcycle accidents in Los Angeles and other busy cities.
Lane Splitting and Accident Liability
Even though lane splitting is legal, riders can still be found at fault if they split lanes recklessly or at unsafe speeds. Insurance companies often scrutinize these cases closely. If you were involved in an accident while lane splitting, consult an experienced Los Angeles motorcycle accident lawyer to protect your rights.
Common Lane Splitting Risks
- Drivers changing lanes unexpectedly
- Narrow lane spacing during heavy traffic
- Reduced visibility in blind spots
Wearing bright gear, using your horn or lights, and staying alert can help reduce these risks.
Penalties for Unsafe Lane Splitting
While lane splitting itself is legal, reckless or unsafe lane splitting can result in a traffic citation. Charges may include speeding, unsafe lane changes, or even reckless driving.
Final Thoughts
Understanding California lane splitting laws is essential for every rider. When done correctly, lane splitting can be safe and efficient, but it also carries risks that require extra caution.
