If you are in a motorcycle accident while lane-splitting you may be wondering who is at fault and how liability gets determined. Lane-splitting is legal in California when done safely. But being legal does not mean every accident involving lane-splitting is automatically the motorcyclist’s fault. The details matter deeply.
What Lane-Splitting Is
Lane-splitting, also called lane-sharing or white-lining, refers to riding a motorcycle between lanes of slow or stopped traffic. California law allows it under guidelines set by law enforcement. Motorcyclists are advised to split lanes only when safe and to avoid excessive speed.
How Fault Is Determined
Fault in a lane-splitting accident depends on many factors. If the motorcyclist was splitting lanes recklessly or dangerously weaving at high speeds they may bear some or all fault. At the same time if another driver changes lanes without signaling, opens a door, or makes a sudden movement without checking blind spots that driver may be liable. California uses comparative negligence meaning multiple parties can share responsibility and compensation is adjusted by each party’s percentage of fault.
Common Causes in Lane-Splitting Crashes
- Drivers failing to check mirrors or blind spots before changing lanes
- Abrupt lane changes without signaling
- Motorcyclists riding too fast while lane-splitting or weaving unpredictably
- Heavy traffic or congestion increasing risk of unpredictable behavior by either driver
How Insurers Approach Lane-Splitting Cases
Insurance companies often examine whether the motorcyclist followed the safety guidelines. If the motorcyclist was riding responsibly and followed lane-splitting rules there is still possibility for recovery. But if the insurer believes the motorcyclist behaved recklessly, they may try to reduce or deny the claim.
What To Do After a Lane-Splitting Accident
- Seek medical attention immediately even if you feel fine at first because some injuries show up later
- Report the accident to law enforcement so there is a formal record
- Gather evidence at the scene such as photos of vehicle positions, damage, road conditions and lane markings
- Collect witness statements and contact information
- Be careful what you say. Avoid admitting fault when speaking with drivers, the police or insurers
- Notify your own insurer but consult with a lawyer before giving detailed statements
Types of Injuries That Often Happen
Motorcyclists involved in lane-splitting accidents may suffer serious injuries such as traumatic brain injury, spinal cord damage, broken bones, road rash, or other significant soft tissue and internal injuries.
What You Could Recover
If another driver’s negligence caused or contributed to the crash you may be entitled to compensation for medical bills, lost wages, pain and suffering, property damage and possibly future medical costs related to your injuries. The amount depends on how negligence is assigned under California law.
