Lane splitting, where a motorcyclist rides between lanes of slower or stopped traffic, is a common sight on Glendale’s congested freeways and surface streets, especially near the 134/5 interchange during rush hour. California is one of the few states that explicitly permits it, but that doesn’t stop insurance companies from treating any lane-splitting rider as automatically at fault the moment a crash happens. Understanding how fault actually works in these cases can make the difference between a fair settlement and a denied claim.
If you were involved in a lane-splitting accident in Glendale, a Glendale motorcycle accident lawyer can help you push back against unfair assumptions and pursue the compensation you’re owed.
Lane Splitting Is Legal in California
Unlike most states, California law does not prohibit lane splitting. The California Highway Patrol has published safety guidelines describing how a rider can lane split more safely, but these are guidelines, not strict legal requirements with specific numeric limits written into the Vehicle Code. Because there is no bright-line speed differential or precise definition written into the statute itself, disputes over whether a particular instance of lane splitting was done “safely” often become a central issue after a crash.
The fact that lane splitting is legal means a rider cannot be found automatically at fault simply for doing it. Fault still depends on how each party involved actually behaved leading up to the collision.
Why Insurers Treat Lane-Splitting Crashes Differently
Adjusters and even some jurors often start from an assumption that a lane-splitting rider was already doing something risky, which can bleed into an unfair assumption that the rider caused the crash. This bias shows up in several ways:
- Assuming excessive speed differential, even without evidence establishing the actual speeds involved
- Treating the mere act of lane splitting as evidence of recklessness
- Discounting driver negligence, such as an unsafe lane change, because the rider was in a position the driver “didn’t expect”
- Applying a harsher standard to the rider than to the driver for the same type of inattention
A thorough, evidence-based investigation is often necessary to counter these assumptions and establish what actually happened.
Common Lane-Splitting Crash Scenarios
- A driver changing lanes without checking mirrors or blind spots, moving into the space a lane-splitting rider is occupying
- A driver opening a door while stopped in traffic, not expecting a rider to be passing between lanes
- Sudden, unsignaled lane changes in heavy interchange traffic near the 134/5
- A driver drifting within their lane due to distraction, encroaching into the rider’s path
- A vehicle suddenly braking in a way that surprises a rider who had a legal expectation of continued traffic flow
- A rider misjudging available space between vehicles, particularly in unusually narrow lanes
Each scenario requires a different fault analysis, and the driver’s conduct is often just as relevant, if not more relevant, than the rider’s.
What the CHP Guidelines Generally Suggest
The California Highway Patrol’s safety tips for lane splitting generally advise riders to consider factors such as:
- Traveling at a speed no more than roughly 10 mph faster than surrounding traffic
- Lane splitting more cautiously, or not at all, when overall traffic speeds are high
- Avoiding lane splitting next to large vehicles, such as trucks or buses, due to reduced visibility
- Being cognizant of lane width and the space available
These are safety recommendations rather than strict legal thresholds. A rider who exceeded a suggested guideline is not automatically at fault, and a rider who followed every guideline can still be found partly at fault if their specific conduct in the moment was unreasonable. The actual facts of your crash, not a generic guideline, determine legal fault.
How Fault Is Actually Determined
Building a fair fault analysis in a lane-splitting case typically involves examining:
- The speed of the rider relative to surrounding traffic, established through witness accounts, physical evidence, or expert reconstruction
- The speed differential between the motorcycle and the vehicles it was passing
- Whether the driver signaled before changing lanes or opening a door
- Whether the driver checked mirrors and blind spots
- The width of the lanes and the space available for safe passing
- Visibility conditions at the time of the crash
- Whether either party was distracted
This kind of analysis often benefits from an accident reconstruction expert, particularly in cases where liability is seriously disputed.
Comparative Negligence in Lane-Splitting Cases
California follows pure comparative negligence. If a rider is found partly at fault, for example due to an unreasonably high speed differential, their compensation is reduced by that percentage but not eliminated. For example, if a rider is found 25% at fault for a $200,000 loss, they could still recover $150,000.
This is an important point for riders to understand: even if some fault is assigned for how the lane splitting was performed, a driver’s separate negligence, such as an unsafe lane change without checking mirrors, can still result in substantial recovery. Fault is not all-or-nothing.
Evidence That Matters in Lane-Splitting Disputes
- The police collision report, including the officer’s observations and any statements taken at the scene
- Witness statements from other drivers who observed the speeds and positions of the vehicles involved
- Dash-cam footage, either from the involved vehicles or from other drivers nearby, which is increasingly common and can be decisive
- Surveillance footage from businesses along the route
- Physical evidence, such as skid marks, debris location, and vehicle damage patterns
- Cell phone records, if driver distraction is suspected
- Accident reconstruction analysis, which can estimate speeds and positions based on physical evidence
Because fault disputes in these cases often come down to speed and positioning, physical and video evidence carries significant weight.
Common Injuries in Lane-Splitting Accidents
- Traumatic brain injuries and concussions
- Road rash, often severe given the mechanics of a lane-splitting collision
- Broken bones, particularly in the arms, legs, and hands from bracing or impact
- Spinal cord injuries
- Internal injuries
- Emotional trauma, including anxiety about riding in traffic afterward
What to Do After a Lane-Splitting Accident
- Call 911 and request police and medical help.
- Get medical attention immediately, even if you feel capable of moving.
- Photograph the scene: the position of both vehicles, lane markings, available space between lanes, skid marks, and your injuries and gear.
- Get witness information, which is especially valuable in these disputed-fault cases.
- Do not admit to speeding or discuss your speed at the scene, since these statements can be used against you even if inaccurate or made under stress.
- Preserve your motorcycle and gear without repair or disposal.
- Do not give a recorded statement to an insurance company before speaking with an attorney, given how quickly adjusters may try to establish an unfavorable speed narrative.
- Follow your treatment plan and keep all medical records.
- Contact an attorney early, particularly one experienced in reconstructing lane-splitting fault disputes.
How Insurers Fight These Claims
- Assuming or asserting an unreasonably high speed differential without solid evidentiary basis
- Characterizing any lane splitting as inherently reckless, contrary to California law
- Minimizing the driver’s own negligence, such as failing to signal or check mirrors
- Offering a quick, low settlement hoping the rider won’t push back on an unfair fault assessment
Compensation You May Be Able to Recover
- Medical expenses: emergency care, surgery, rehabilitation, and future treatment
- Lost wages and loss of earning capacity
- Motorcycle repair or replacement, along with damaged gear
- Pain and suffering, emotional distress, and loss of enjoyment of life
- Wrongful death damages for surviving family members, if the crash was fatal
Deadlines to Keep in Mind
- Personal injury lawsuits: generally two years from the date of the accident
- Property damage claims: generally three years
- Wrongful death claims: generally two years from the date of death
How a Glendale Motorcycle Accident Lawyer Can Help
An experienced attorney can:
- Investigate the crash without accepting an insurer’s default assumption of rider fault
- Work with accident reconstruction experts to establish actual speeds and positions
- Gather witness statements and available video evidence
- Push back against mischaracterizations of California’s lane-splitting law
- Calculate the full value of your current and future losses
- Negotiate firmly, or file suit and pursue the case through trial if necessary
Many personal injury firms work on a contingency fee basis, meaning you typically pay no attorney fees unless you recover compensation. Confirm the terms during your consultation.
