Lane splitting is legal in California, but that does not stop insurance companies from blaming the rider when a crash happens. If a driver hit you while you were filtering between lanes, you may be entitled to compensation, and you do not have to accept the insurer’s version of events.
The California lane-splitting accident lawyers at Berg Injury Lawyers have spent over 45 years standing up to insurers for injured Northern California riders. Our experienced motorcycle accident attorneys can investigate what happened, push back on unfair blame, and fight for the money you deserve. Contact our team now for a free consultation.
Lane Splitting Is Legal in California
California is the only state that expressly allows motorcyclists to ride between lanes of moving traffic. Under California Vehicle Code Section 21658.1, lane splitting is defined as riding a motorcycle between rows of stopped or moving vehicles in the same lane. It is a normal, lawful way to ride on crowded California roads.
The California Highway Patrol publishes safety guidelines for lane splitting, such as watching your speed relative to traffic and staying out of other drivers’ blind spots. Those guidelines are educational. They are not law, and the statute itself sets no fixed speed limit for splitting.
The distinction between the legislated law and the guidelines matters. A rider cannot be found at fault simply for lane splitting at the time of an accident, and an insurance company cannot deny your claim just because you were riding between lanes when the collision happened.
How Fault Is Determined in a Lane-Splitting Crash
Fault in a lane-splitting crash comes down to negligence, which means figuring out who failed to drive with reasonable care. Lane splitting being legal does not automatically make the other driver responsible, but it does keep the focus where it belongs: on how each person was driving.
Most lane-splitting collisions trace back to a driver’s choice. Under California Vehicle Code Section 22107, drivers must make sure a lane change can be done safely and signal before moving over. A driver who drifts into your path without checking mirrors and blind spots, or who opens a door in front of you, has broken that duty. “I didn’t see the motorcycle” is one of the oldest lines in traffic collisions, and it is not a legal defense.
Proving what happened takes evidence. Our team can investigate the scene, pull traffic and surveillance footage, interview witnesses, and work with accident reconstruction professionals to show how the crash really unfolded. The sooner that work starts, the more evidence we can protect.
Can You Recover If You Were Partly at Fault?
California follows a pure comparative negligence rule, so being partly at fault does not bar you from recovering compensation. If you share some of the blame, your recovery is reduced by your percentage of fault, but you can still pursue a claim.
Here is what that looks like in practice. If an insurer argues you were 20 percent responsible for a crash, you would still be able to recover the remaining share of your damages. Even a rider found mostly at fault can recover something. That is very different from the all-or-nothing rule some other states use, and it is why an insurer’s early blame is not the final word.
Because the exact percentage drives the size of a claim, insurers often push a high fault number early to shrink what they pay. You may be entitled to compensation even when the insurance company insists the crash was mostly your doing.
How Insurance Companies Try to Blame Lane-Splitting Riders
Insurance companies have a familiar playbook for lane-splitting claims. The goal is to shift blame onto the rider so the carrier can pay less or deny the claim outright.
Knowing about these arguments ahead of time empowers you to dispute them:
- “You came out of nowhere.” This usually means the driver never checked mirrors or blind spots before changing lanes. A driver’s failure to look is not your fault.
- “You were going too fast.” The CHP suggests keeping your speed close to traffic, but that is guidance, not a speed limit written into the law. Whether your speed was reasonable depends on traffic, lane width, weather, and road conditions, not a single number.
- “You did not wear a helmet.” California requires a DOT-compliant helmet under Vehicle Code Section 27803. Even when a helmet question comes up, it can only affect head or facial injuries, not unrelated harm like broken bones or road rash on your legs.
- “You created the risk by lane splitting.” Lane splitting is a legal activity, so choosing to do it does not erase a careless driver’s responsibility.
The strongest answer to each of these is evidence. Acting quickly helps preserve surveillance video, witness memories, and physical clues at the scene before they are gone. Footage from nearby businesses is often recorded over within days, so early action can make or break a claim.
Common Lane-Splitting Crash Scenarios
Most lane-splitting crashes follow a handful of patterns. Recognizing yours helps show why the other driver, not you, caused the collision.
- Unsafe Lane Changes: A driver moves over without checking for a filtering motorcycle. This is the single most common lane-splitting crash.
- Dooring: A driver or passenger in stopped traffic opens a door into the path of a passing rider.
- Drifting in Traffic: A driver eases toward the lane line in slow, stop-and-go traffic and closes the gap a rider is moving through.
- Sudden Stops and Swerves: A car brakes or swerves without warning, leaving a filtering rider no room to react.
- Rideshare Pickups: An Uber or Lyft driver stops abruptly to grab a passenger, cutting off a rider between lanes.
- Large Trucks and Commercial Vehicles: Big rigs have wide blind spots and long turning paths that create serious hazards for riders. Crashes with large trucks often cause the most severe injuries.
When the driver who hit you has no insurance or flees the scene, your own uninsured or underinsured motorist coverage may step in to cover your losses. We can review your policy and every possible source of recovery.
Injuries in Lane-Splitting Motorcycle Crashes
A rider has almost nothing between their body and the road, so lane-splitting crashes tend to cause serious harm even at lower speeds. The injuries our clients face often include:
- Road Rash and Abrasions: Deep skin and tissue damage from sliding across pavement
- Broken Bones: Fractures to arms, legs, wrists, and ribs from the impact and the fall
- Spinal Cord Injuries: Damage to the spinal cord can lead to lasting mobility problems
- Traumatic Brain Injuries: Head trauma that can happen even when a rider wears a helmet
- Internal Injuries: Organ damage and internal bleeding that may not be obvious right away
Because some injuries take time to become visible, seeing a doctor quickly protects both your health and your claim. A medical record that starts the day of the crash connects your injuries to the collision.
What to Do After a Lane-Splitting Accident in California
The steps you take after a crash shape both your recovery and your claim. If you are able, focus on a few priorities:
- Get Medical Care First: Let paramedics check you, and follow up even if you feel okay, since adrenaline can hide serious injuries.
- Document the Scene: Photograph the vehicles, the road, lane markings, and your gear if you can do so safely.
- Collect Information: Get the other driver’s details and the names and numbers of any witnesses.
- Say Little to the Insurer: Do not give a recorded statement or admit fault, and do not accept a quick settlement offer before you understand your injuries.
When you talk to a lawyer, bring whatever you have: the police report, your photos, your medical records, and your account of how the other driver was behaving. Those details help us evaluate your claim and start building it right away.

Frequently Asked Questions
Is Lane Splitting Legal in California?
Yes. California Vehicle Code Section 21658.1 has expressly allowed lane splitting since January 1, 2017. California is the only state that permits riding between lanes of moving traffic, so a rider cannot be cited or found at fault simply for splitting.
Does Lane Splitting Automatically Make Me at Fault for the Crash?
No. Because lane splitting is legal, it is not evidence of negligence on its own. Fault depends on how each driver was behaving, such as whether a driver changed lanes or opened a door without checking for a rider.
Can I Still Recover Compensation if I Was Partly at Fault?
Yes. California uses a pure comparative negligence rule, so partial fault does not bar your claim. Your recovery is reduced by your percentage of fault, but you may still pursue the rest of your damages.
What if the Insurance Company Says I Was Splitting Too Fast or Riding Outside the CHP Guidelines?
CHP guidelines are educational, not law, and the lane-splitting statute sets no fixed speed limit. Whether your speed was reasonable depends on the traffic, weather, and road conditions at the time, not a single number an adjuster points to. Evidence and, when needed, accident reconstruction can show that your riding was reasonable.
What Should I Tell a Lawyer After a Lane-Splitting Crash?
Share everything you have about how the crash happened and what the other driver did. Bring the police report, photos, medical records, and witness information if you have them. Even small details can help an attorney evaluate and build your claim.
What if the Driver Who Hit Me Did Not Have Insurance?
You may still have a path to compensation through your own uninsured or underinsured motorist coverage. This coverage can also apply in hit-and-run crashes. We can review your policy to find every available source of recovery.
