Motorcycle Accidents in Los Angeles: Lane Splitting Laws and Liability

Los Angeles has some of the worst traffic in the country, and motorcyclists feel it more than anyone. Lane splitting is legal in California, but the rules around it are misunderstood by riders and drivers alike. The California Office of Traffic Safety reported 583 motorcyclist deaths in 2023, down from 649 in 2022 but still nearly 19% higher than 2019. Many of those deaths happened on the freeways and surface streets of Los Angeles County, where high traffic density and aggressive driving create constant danger.

I’m Mikoe Tretola, and I’ve represented riders who were following every rule and still got blamed for their injuries because they happened to be lane splitting when a distracted driver changed lanes without looking. At Mister Wolf P.C., our Los Angeles personal injury lawyers know how to build motorcycle accident cases that survive the bias many jurors hold against riders. The law on lane splitting, how fault gets assigned in LA motorcycle crashes, and what to do if you’re injured on the road are covered below.

Is Lane Splitting Legal in Los Angeles?

Yes. California Vehicle Code Section 21658.1, which took effect in 2017, defines lane splitting as riding a motorcycle between rows of stopped or moving vehicles in the same lane. The statute doesn’t set specific speed limits for lane splitting. Instead, it directed the California Highway Patrol to develop educational guidelines for safe lane splitting practices.

CHP safety tips are not speed caps

The CHP’s current lane-splitting safety tips do not set a fixed 30 mph traffic limit or a 10 mph speed-differential rule. They warn that danger increases as overall speed and speed differential increase, advise riders to consider lane width, vehicle size, road conditions, weather, and lighting, and say it is typically safer to split between the far left lanes than elsewhere. They also remind riders that shoulder riding is illegal and is not lane splitting.

A rider lane splitting at 15 mph through stopped traffic on the 101 near Hollywood is behaving very differently than a rider weaving between cars at 55 mph on the 405 through the Sepulveda Pass. Both are technically lane splitting under the statute. Only one looks reasonable to a jury of twelve people, most of whom have never ridden a motorcycle.

Insurance adjusters and defense attorneys still use the CHP tips as a reasonableness framework. If the traffic was slow, the speed difference was modest, you stayed out of blind spots, and you avoided large vehicles, you have a stronger argument that you were riding prudently. If you were splitting at highway speed through narrow gaps, the defense will hammer that point. Keep this in mind every time you ride.

How Does Fault Work in LA Motorcycle Accidents Involving Lane Splitting?

California uses pure comparative negligence, a concept we explain in detail in our guide on what a personal injury lawyer does for you. Every party’s fault is assigned a percentage, and your recovery is reduced by your share. A rider found 20% at fault recovers 80% of their damages. A rider found 60% at fault still recovers 40%.

Lane splitting doesn’t automatically make the rider at fault. But it introduces a fact question: was the rider splitting safely? Insurance adjusters and defense attorneys will argue that any crash during a lane split was the rider’s fault. They’ll point to speed, proximity to other vehicles, road conditions, and time of day.

The CHP tips become the measuring stick. Low surrounding speeds, a small speed differential, visibility, lane position, weather, and nearby trucks or buses all matter. If you were splitting at highway speeds through fast-moving traffic, or weaving aggressively through lanes, the fault allocation shifts against you.

Most motorcycle accidents during lane splitting happen because a driver failed to check their mirrors or blind spot before changing lanes. Under Vehicle Code Section 22107, no person shall turn a vehicle or move right or left upon a roadway until the movement can be made with reasonable safety. A driver who changes lanes into a legally lane-splitting motorcyclist bears significant fault for the collision.

Distracted driving is epidemic in Los Angeles. Drivers texting, checking GPS apps, adjusting playlists, or looking at their phones account for a huge percentage of the lane-change collisions that injure riders on LA freeways. I’ve obtained cell phone records in discovery that proved a driver was actively texting at the exact moment they swerved into a client’s motorcycle on Mulholland Drive. That evidence turned a contested liability case into a clear defense liability case.

If you’re in a crash while lane splitting, photograph the position of both vehicles immediately before anything moves. The lane positions and vehicle orientations tell the story of who moved where, and that story is worth more than any witness statement.

What Are the Most Dangerous Roads for Motorcyclists in Los Angeles?

Los Angeles has specific corridors where motorcycle accidents concentrate year after year. Knowing these roads helps you ride with appropriate caution.

Freeways. The 405, 101, and 10 freeways are the most common sites for motorcycle crashes in LA County. The 405 through the Sepulveda Pass is particularly dangerous because of sharp curves, heavy traffic, and aggressive lane changes by commuters trying to save seconds. The 101 through Hollywood and the San Fernando Valley sees constant stop-and-go traffic that increases lane-splitting collisions. Drivers who are stationary one moment and accelerating the next create unpredictable hazards. The 10 through downtown Los Angeles combines heavy truck traffic with lane merges and freeway connections that catch riders off guard, especially near the 10/110 interchange.

Surface Streets and Canyons.

Pacific Coast Highway through Malibu is iconic for motorcycle riding but extremely dangerous. Blind curves, inconsistent road surfaces, and drivers pulling out of beachside parking lots create constant hazards. The intersection of PCH and Topanga Canyon Boulevard is a known collision hotspot where turning vehicles cross the paths of riders and cyclists at high speed.

Mulholland Drive and Mulholland Highway attract sport riders every weekend. The winding roads look inviting, but gravel on curves, oil slicks from vehicle leaks, and oncoming traffic crossing the center line cause serious crashes. Canyon roads like Decker Canyon Road and Latigo Canyon Road in the Santa Monica Mountains are just as hazardous, with steep drop-offs and no guardrails on many sections.

Sunset Boulevard through the Palisades and Bel Air has blind curves and cross-traffic from driveways that drivers use aggressively. The stretch of Sepulveda Boulevard near LAX sees heavy commercial vehicle traffic that’s dangerous for riders of any experience level.

Know the roads you ride. If you regularly commute on the 405 or ride PCH on weekends, invest in a helmet-mounted camera. That footage is often the difference between a successful claim and a denied one.

What California Laws Protect Motorcyclists?

Several statutes specifically protect motorcycle riders in California and give you legal rights that many drivers don’t realize you have.

Helmet Requirements. Vehicle Code Section 27803 requires all motorcycle riders and passengers to wear a DOT-approved helmet while operating or riding on a motorcycle on any roadway. Failure to wear a helmet can be used against you in a personal injury case to reduce your damages under comparative fault, particularly if you suffered a head injury. A defense attorney will argue that a helmet would have prevented or reduced your head injuries, even if the primary cause of the crash was the other driver’s negligence. Wearing a proper helmet protects your life and your legal claim. Replace your helmet after any impact, even a minor one. Helmets are designed to absorb one impact, not multiple.

Same Rights as Other Vehicles.

Under the California Vehicle Code, motorcyclists have the same rights and duties as other vehicle operators on the road. A driver can’t argue that a motorcyclist “assumed the risk” simply by choosing to ride a motorcycle. Every driver owes the same duty of care to riders as they do to other cars. This principle is well established in California law and becomes relevant every time a defense attorney tries to paint the rider as inherently reckless.

Uninsured Motorist Coverage.

Uninsured and underinsured motorist (UM/UIM) coverage is critical for riders in Los Angeles. Many at-fault drivers carry only the state minimum insurance ($30,000 per person as of 2025 renewal), which barely covers emergency room transport after a serious motorcycle crash. If your own policy includes UM/UIM coverage, it fills the gap when the at-fault driver’s insurance isn’t enough.

Pull out your motorcycle insurance policy today. Check your UM/UIM coverage limits. If you don’t carry UM/UIM coverage, or if your limits are low, call your broker and increase them. The additional premium is typically modest relative to the protection it provides. This is one of the single most important financial decisions a motorcyclist in LA can make.

What Injuries Are Common in Los Angeles Motorcycle Accidents?

Motorcycle crashes produce injuries that are categorically more severe than car-on-car collisions. Riders have no steel cage, no airbags, and minimal protection beyond their helmet and gear. The human body absorbs the full force of impact.

Road Rash and Soft Tissue Injuries.

Road rash ranges from surface abrasions to deep wounds that expose muscle, tendon, and bone. Severe road rash requires skin grafts, wound vac therapy, and months of wound care. These injuries leave permanent scarring that affects appearance and self-confidence. Insurance adjusters routinely undervalue road rash, treating it as a minor abrasion when the reality is weeks of painful treatment and lasting disfigurement.

Traumatic Brain Injuries.

Even with a DOT-approved helmet, traumatic brain injuries (TBIs) occur in motorcycle accidents. The force of impact can cause concussions, brain contusions, and diffuse axonal injuries. TBIs can result in cognitive deficits, personality changes, memory loss, and permanent disability. These injuries often don’t show up on initial CT scans, making early and repeated neurological evaluation essential. If you hit your head in a crash, insist on follow-up evaluations even if the ER says you’re fine.

Spinal Cord and Orthopedic Injuries.

Spinal cord damage from motorcycle crashes can cause partial or complete paralysis. The lifetime cost of care for a spinal cord injury can exceed $5 million according to the National Spinal Cord Injury Statistical Center. Broken legs, shattered ankles, fractured wrists, and pelvis fractures are standard motorcycle crash injuries. Many require surgery with hardware installation, and recovery takes months. Some injuries result in permanent limitations that change how you work, exercise, and live.

If you’ve been in a motorcycle accident, see a doctor the same day, even if you walked away from the scene. Adrenaline masks pain for hours. Get imaging done. Follow up with specialists. Document everything from day one, because gaps in medical treatment give insurance companies ammunition to argue your injuries aren’t serious.

How Do You Preserve Evidence After a Motorcycle Accident in LA?

Evidence disappears fast in Los Angeles. Traffic keeps moving. Road conditions change. Witnesses leave the area within minutes.

At the Scene.

Call 911 and wait for police to arrive and create a report. Photograph everything: the positions of all vehicles, road markings, debris, damage to your motorcycle and gear, your visible injuries, traffic signals, and any skid marks. Get contact information from every witness. Note the time, weather, and lighting conditions. Write all of this down before your memory starts to blur.

Dashcam and Helmet Cam Footage.

If you ride with a camera (and you should), preserve that footage immediately. Don’t overwrite it. Copy it to a computer and a cloud storage service the same day. This footage can prove that you were lane splitting safely, that the driver failed to signal, that the driver was looking at their phone, or that road conditions contributed to the crash.

Electronic Vehicle Data.

Modern vehicles store data about speed, braking, and steering inputs in event data recorders and engine control modules. If the at-fault vehicle has this data, your attorney can send a spoliation letter demanding it be preserved before it’s overwritten during routine maintenance or when the vehicle is repaired.

Damaged Gear.

Save your damaged riding gear. Don’t throw away your helmet, jacket, gloves, or boots. The damage patterns on your gear corroborate the force of impact, the direction of the collision, and the mechanism of your injuries. Your crushed helmet is evidence. Your shredded jacket tells the story of the slide across asphalt.

How Do Insurance Companies Handle Motorcycle Accident Claims in LA?

Poorly. Insurance companies harbor the same biases against motorcyclists that some jurors do. They assume riders are reckless. They blame lane splitting reflexively. They minimize injuries by pointing to the “inherent danger” of riding, as if choosing a motorcycle means you accepted the risk of other drivers being negligent.

Common Adjuster Tactics.

Adjusters will request a recorded statement early, before you’ve seen all your doctors or understood the full extent of your injuries. They’ll offer a quick settlement that doesn’t account for future medical treatment, ongoing physical therapy, or permanent impairment. They’ll request your entire medical history going back years, hoping to find a prior injury they can blame for your current condition. Don’t give a recorded statement to any insurance company without talking to a lawyer first. That statement will be used against you, and you can’t take it back once it’s on the record.

Undervaluation of Claims.

Motorcycle injuries are expensive to treat and slow to heal. Adjusters know this. Their initial offers rarely reflect the true cost of road rash treatment, TBI rehabilitation, or orthopedic surgery followed by months of physical therapy and years of follow-up care. The lowball offer is the insurer’s first and best weapon.

At Mister Wolf P.C., we build motorcycle cases with medical cost projections, life care plans, and economic loss analyses that force insurers to confront the real numbers. Filing suit in LA Superior Court and preparing for trial moves these cases off the adjuster’s desk and into serious settlement territory. An insurer that sees depositions being scheduled and trial dates being set treats the claim differently than one that sees a pro se claimant asking politely for more money.

What Should You Do Right Now If You Were in a Motorcycle Crash in Los Angeles?

Get medical treatment. Today. Not tomorrow. Not when the swelling goes down. Today.

Preserve every piece of evidence you can: photos, helmet cam video, damaged gear, witness contact information, and the police report number. Don’t post about the accident on social media. Don’t discuss fault with the other driver, their insurer, or your own insurer without talking to an attorney first. Don’t accept any settlement offer before you understand the full extent of your injuries, which may take weeks or months of medical evaluation to determine.

Pull out your insurance policy and check your UM/UIM coverage limits. If the at-fault driver was uninsured or underinsured (common in LA), that coverage may be your primary source of recovery. Knowing your limits now prevents surprises later.

Then call a motorcycle accident attorney who has tried these personal injury cases in LA courtrooms. Bring your photos, your medical records, your insurance policy, and your helmet cam footage to the consultation. At Mister Wolf P.C., we evaluate motorcycle accident cases at no charge, and we’ll tell you exactly what your claim is worth based on the evidence, the law, and what we know about how LA juries value motorcycle injury cases.
