Lane-Splitting Motorcycle Accidents in California

Lane splitting is legal in California, but the fact that a motorcyclist was riding between lanes does not automatically determine who caused an accident. A driver may change lanes into a motorcycle, drift toward the rider, open a door, or make another unsafe maneuver while the motorcyclist is lane splitting.

The rider’s conduct can also become part of the liability analysis. Speed, traffic conditions, available space, visibility, surrounding vehicles, and the way both the rider and driver were operating can all matter after a collision.

For an injured motorcyclist, the important question is not simply whether lane splitting occurred. The accident should be evaluated to determine how the collision happened and whether one or more people failed to use reasonable care.

Is Lane Splitting Legal in California?

Yes. California law specifically recognizes lane splitting by motorcycles.

California Vehicle Code section 21658.1 defines lane splitting as driving a motorcycle with two wheels in contact with the ground between rows of stopped or moving vehicles in the same lane or in adjacent lanes. The definition applies on divided and undivided streets, roads, and highways.

California is therefore different from states where riding between lanes is prohibited outright.

Legal Does Not Mean Every Lane-Splitting Maneuver Is Safe

The fact that lane splitting is legal does not mean a rider can operate without regard for speed, traffic, visibility, or surrounding vehicles.

Motorcyclists remain subject to California’s ordinary traffic and safety laws. A rider who travels at an unsafe speed or makes another unreasonable maneuver can still face a comparative-fault argument after an accident.

Likewise, drivers must continue watching for motorcycles and use reasonable care before changing lanes or making other movements.

California Does Not Have One Universal Lane-Splitting Speed Limit

California’s lane-splitting statute does not create one universal numerical speed limit that applies specifically to every lane-splitting situation.

The rider remains subject to applicable speed laws and must operate appropriately for the circumstances. Traffic congestion, lane width, roadway conditions, visibility, surrounding vehicle speed, and the speed difference between the motorcycle and traffic can all affect safety.

A statement that lane splitting becomes automatically illegal above one specific speed would oversimplify California law.

CHP Encourages Riders to Consider Overall Speed and Speed Differences

California Highway Patrol safety guidance emphasizes that the danger of lane splitting increases as overall speed rises and as the speed difference between the motorcycle and surrounding vehicles becomes greater.

Those safety considerations can also become relevant after a collision. An insurer may examine how fast the motorcycle was traveling compared with surrounding traffic, even though California does not impose one separate statutory lane-splitting speed cap.

Lane Splitting Usually Occurs in Congested Traffic

Many lane-splitting accidents occur when cars are stopped or moving slowly on freeways and other congested roads. The motorcyclist may travel between rows of vehicles while drivers are braking, merging, or attempting to change lanes.

Those conditions can create limited space and reduced reaction time. A driver who unexpectedly moves toward another lane may give the rider very little opportunity to avoid a collision.

Drivers Should Expect Motorcycles on California Roads

Because lane splitting is lawful in California, drivers should account for the possibility that a motorcycle may be traveling between lanes.

A driver should not assume that the space between rows of vehicles will always be empty. Checking mirrors and blind spots before changing lanes remains particularly important in congested traffic.

An Unsafe Lane Change Can Cause a Lane-Splitting Accident

One of the most common collision patterns involves a vehicle changing lanes while a motorcycle is traveling between rows of traffic.

A driver may become frustrated with congestion, see an opening, and begin moving without adequately checking for a motorcycle. The motorcycle can be sideswiped, struck directly, or forced into another vehicle.

Video, witnesses, vehicle damage, lane markings, and driver statements can help determine how the lane change occurred.

Turn Signals Do Not Automatically Give a Driver the Right to Move

Using a turn signal is important, but activating a signal does not automatically make a lane change safe.

A driver still must account for surrounding traffic before moving. If a motorcycle is already occupying the space the driver intends to enter, the fact that the driver signaled does not by itself decide liability.

The rider’s position and opportunity to react can also require evaluation.

Drivers May Fail to See Motorcycles in Their Blind Spots

Motorcycles are smaller than passenger vehicles and can be more difficult to notice when drivers rely only on mirrors.

A driver changing lanes should adequately check the surrounding area rather than assuming no vehicle is beside the car. A blind-spot argument does not automatically excuse an unsafe lane change.

The rider’s location, visibility, lighting, and surrounding traffic can all become relevant.

Sudden Lane Changes Are Particularly Dangerous

A motorcyclist traveling between slow-moving vehicles may have only a narrow path available.

When a driver suddenly moves across that path, the rider may have little room to brake or swerve safely. Evasive action can itself lead to a crash with another vehicle or the roadway.

The absence of direct contact does not necessarily mean the driver’s maneuver played no role in the accident.

No-Contact Lane-Splitting Accidents Can Occur

A driver may begin changing lanes and force the motorcyclist to brake or swerve without actually touching the motorcycle.

The rider may then lose control or collide with another vehicle. In those cases, witnesses, dashcams, helmet-camera footage, surveillance, and vehicle movements can become particularly important because there may be no physical impact between the motorcycle and the vehicle that caused the evasive maneuver.

Direct Sideswipe Collisions Can Cause Serious Injuries

A motorcycle can be sideswiped when a car moves laterally into the rider’s path.

Even relatively limited contact with the motorcycle, handlebars, rider, or riding equipment can destabilize the bike. Once the rider loses balance, contact with other vehicles or pavement can cause severe injuries.

The amount of damage to the car does not necessarily reflect the severity of the rider’s injuries.

Drivers Can Drift Without Intentionally Changing Lanes

Not every lane-splitting accident involves a deliberate lane change. A distracted, fatigued, or inattentive driver may gradually drift toward the lane line.

A rider traveling between vehicles may be struck or forced into another car. Dashcam footage and roadway evidence can help distinguish a deliberate lane change from unintentional drift.

Distracted Driving Can Contribute to Lane-Splitting Accidents

A driver using a phone, navigation system, infotainment screen, food, or another distraction may fail to notice a motorcycle approaching between lanes.

The existence of a phone inside the vehicle does not automatically prove distraction. Witnesses, video, driver statements, electronic evidence obtained appropriately, and the driver’s movements can help establish whether inattention contributed.

Learn more in Motorcycle Accidents Caused by Distracted Drivers in California.

Heavy Traffic Can Increase Driver Distraction

Stop-and-go traffic can encourage drivers to look at phones, adjust navigation, or focus on finding a faster lane.

At the same time, motorcyclists may be moving between those vehicles. This combination can create a collision when a driver suddenly moves or fails to notice the approaching motorcycle.

The particular driver behavior still must be proven rather than assumed.

Drivers May Move to Block a Lane-Splitting Motorcycle

A driver may become frustrated when a motorcycle passes between lanes and intentionally move toward the rider’s path.

Deliberately creating a hazard for a motorcyclist can be extremely dangerous. Evidence such as video, witnesses, driver statements, repeated movements, or surrounding traffic can become important when intentional conduct is alleged.

A rider should prioritize safety rather than confronting the driver.

Do Not Escalate a Road-Rage Situation

A rider involved in a hostile interaction should avoid pursuing, challenging, or retaliating against another driver.

If a driver intentionally threatens or endangers the motorcyclist, move to a safer location when possible and contact law enforcement as appropriate. Road-rage evidence can be preserved without creating another dangerous encounter.

Lane Splitting and Riding on the Shoulder Are Different

California’s recognition of lane splitting does not mean motorcyclists generally have permission to ride on the shoulder to bypass traffic.

CHP guidance specifically distinguishes shoulder riding from lane splitting and states that riding on the shoulder is illegal. A collision involving the shoulder can therefore present different issues from a collision occurring between rows of traffic.

The precise location of the motorcycle should be documented when disputed.

Roadway Photographs Can Help Establish Where the Rider Was Traveling

After a serious collision, photographs can document the lanes, shoulder, lane lines, HOV markings, barriers, traffic conditions, and available space.

This can become important when a driver or insurer claims the motorcyclist was riding on the shoulder rather than legally splitting between lanes.

Video can provide even stronger evidence when the exact motorcycle position is disputed.

Lane Width Can Affect Safety

Some lanes provide substantially more room between vehicles than others. Large trucks, buses, SUVs, and wider vehicles can reduce the available space for a motorcycle.

CHP advises riders to consider the total environment, including lane width and the size of surrounding vehicles. Those same facts can become important after a collision when evaluating whether the rider and driver acted reasonably.

Large Trucks Can Create Additional Lane-Splitting Hazards

A motorcycle traveling next to a tractor-trailer, bus, motorhome, or other large vehicle can be difficult for the driver to see.

Large vehicles also have significant blind spots and can leave less room between lanes. CHP advises caution around large vehicles while lane splitting.

When a commercial vehicle is involved in a collision, additional employer and insurance issues may also require investigation.

A Commercial Driver May Have Different Visibility Limitations

Truck and bus drivers often rely heavily on mirrors and may have substantial areas around the vehicle that are difficult to see.

That does not automatically excuse an unsafe lane movement. Commercial drivers still must use appropriate care when changing lanes or maneuvering around motorcycles.

Camera systems, vehicle data, mirrors, witnesses, and commercial records can become useful evidence.

HOV and Carpool Lanes Can Be Common Lane-Splitting Areas

Motorcyclists frequently travel near the far-left portions of California freeways, including areas near high-occupancy vehicle lanes.

A collision can occur when another vehicle crosses into or out of the lane without adequately checking for a motorcycle. Road markings, permissible entry points, signals, and surrounding traffic can all become relevant.

Solid or Broken Lane Markings Can Provide Context

The type of lane marking at the crash location may help explain whether and where another vehicle was permitted to move.

The marking itself does not necessarily determine civil liability. A driver making an otherwise permitted lane movement must still use reasonable care before entering a space occupied by a motorcycle.

Lane Splitting Does Not Give Riders a Guaranteed Right of Way

The legality of lane splitting should not be interpreted to mean that a motorcycle always has an absolute right to continue between vehicles regardless of conditions.

Riders remain responsible for operating safely and responding to foreseeable traffic changes. A rider’s speed, positioning, and reaction to surrounding vehicles can become relevant after an accident.

Drivers Also Cannot Treat Lane Splitting as Automatically Negligent

An insurer may focus heavily on the fact that the rider was between lanes. That fact alone does not establish fault because California expressly recognizes lane splitting.

The analysis should focus on how the rider was operating, what the other driver did, and how those actions contributed to the collision.

Comparative Fault Can Apply in Lane-Splitting Accidents

California uses comparative-fault principles. This means responsibility can be divided when both the motorcyclist and another driver contributed to the accident.

For example, a driver may make an unsafe lane change while the rider is alleged to have been traveling too fast for the conditions. A factfinder may evaluate both actions rather than treating the entire accident as one person’s fault.

Comparative Fault Does Not Automatically Eliminate the Rider’s Claim

Even if the motorcyclist is found partially responsible, that does not necessarily mean the rider recovers nothing.

California generally allows damages to be reduced according to the injured person’s supported percentage of fault. The actual allocation should be based on evidence rather than assumptions about motorcycle riding.

Speed Is Often Disputed After a Lane-Splitting Crash

A driver may claim the motorcycle appeared suddenly and was traveling too quickly, while the rider may state that traffic was nearly stopped and the motorcycle was moving cautiously.

Video, witnesses, motorcycle damage, vehicle data, skid evidence, and accident reconstruction can help evaluate those competing accounts.

A driver’s inability to see the motorcycle until impact does not, by itself, establish excessive motorcycle speed.

There Is No Automatic “Too Fast to Lane Split” Number in the Statute

California law does not create one separate numerical threshold above which every act of lane splitting automatically becomes illegal.

Applicable speed laws and reasonable operation still matter. CHP also advises that risk increases with higher overall speeds and greater speed differences between the motorcycle and surrounding traffic.

The actual conditions should therefore be evaluated rather than relying on a made-up universal number.

Speed Differential Can Affect Reaction Time

A rider traveling substantially faster than surrounding vehicles may have less time to react if a driver begins changing lanes.

Likewise, a driver who fails to check before moving can create a danger even when the motorcycle is traveling cautiously. Both the rider’s speed and the driver’s conduct may therefore matter.

Slow Traffic Does Not Eliminate Collision Risk

Many riders lane split specifically because surrounding traffic is slow or stopped.

A stopped driver may unexpectedly open a door, move toward another lane, or attempt to reposition. Slow vehicle speed can reduce certain risks while creating others.

Drivers should continue checking for motorcycles even when traffic is nearly stationary.

Door-Opening Accidents Can Occur in Congested Traffic

A driver or passenger may open a vehicle door while traffic is stopped or slow.

A motorcyclist traveling between lanes can have little time to avoid the door. California generally restricts opening a vehicle door on the side available to moving traffic unless it can be done safely without interfering with traffic.

Vehicle position, door damage, witness statements, and video can become important evidence.

The Person Who Opened the Door Can Matter

The person opening the door may be the driver or a passenger.

Liability should therefore not automatically be assigned to the vehicle operator without investigating who actually opened the door and why. The driver’s stopping position and surrounding circumstances can still be relevant.

Merging Traffic Can Create Lane-Splitting Hazards

Freeway entrances, exits, lane reductions, and congested merges often cause drivers to make quick movements.

A motorcycle splitting lanes near a merge may encounter vehicles crossing several lanes or searching for openings. The rider and surrounding drivers should account for the changing traffic pattern.

When a collision occurs, roadway design and vehicle movements can help explain the sequence.

Construction Zones Can Reduce Available Space

Temporary barriers, narrowed lanes, lane shifts, construction vehicles, and changing markings can make lane splitting more difficult.

A driver may also be unfamiliar with the temporary configuration. Whether the rider’s conduct was appropriate and whether another driver used reasonable care should be evaluated from the actual construction conditions.

Weather Can Affect Lane-Splitting Safety

Rain can reduce visibility and traction while increasing stopping distances. Wind, glare, darkness, and other conditions can also affect motorcycle stability and driver awareness.

Lane splitting remains subject to the same need to operate appropriately for the conditions. Weather can therefore become relevant to both rider and driver conduct after a collision.

Nighttime Lane Splitting Can Create Visibility Issues

At night, a driver may have more difficulty judging the position or speed of an approaching motorcycle.

Motorcycle lighting, reflective equipment, surrounding headlights, road lighting, and vehicle mirrors can all become relevant. The fact that the accident occurred at night does not automatically establish fault for either party.

Motorcycle Visibility Can Become a Disputed Issue

A driver may claim that the motorcycle was difficult to see because of traffic, vehicle position, lighting, or other circumstances.

Evidence concerning the motorcycle’s headlight, reflective equipment, lane position, and surrounding vehicles can help evaluate that argument. Drivers are still expected to watch for motorcycles even when traffic is congested.

A Driver’s Statement That the Motorcycle “Came Out of Nowhere” Should Be Examined Carefully

After a collision, drivers sometimes describe motorcycles as appearing suddenly.

That statement may reflect motorcycle speed, but it can also reflect inadequate mirror or blind-spot checks. Video, witnesses, roadway conditions, and vehicle positions can provide a more objective account.

The phrase itself should not be treated as proof of how the accident occurred.

Motorcycle Cameras Can Be Valuable Evidence

Helmet-mounted or motorcycle-mounted cameras can provide a direct view of lane-splitting conditions before a collision.

Footage can show traffic speed, available space, lane position, vehicle movement, turn signals, and the rider’s own speed relative to surrounding traffic. Preserve the complete original file rather than only a shortened clip.

Other Drivers’ Dashcams Can Help

Nearby motorists may have dashcams that captured the collision from another angle.

A third-party recording can be particularly valuable when the rider and driver disagree about whether the vehicle suddenly changed lanes or whether the motorcycle was moving excessively fast.

Commercial vehicles may also have fleet-camera systems.

Surveillance May Capture Part of the Accident

Some lane-splitting accidents occur near businesses, overpasses, intersections, parking facilities, or other locations with cameras.

A recording does not have to show the entire collision to be useful. Video immediately before the crash may establish traffic congestion, vehicle positions, or the rider’s movement.

Potential footage should be identified promptly because recordings may be overwritten.

Witnesses Can Help Establish Traffic Conditions

A nearby driver may be able to describe whether traffic was stopped, moving slowly, or traveling at freeway speed.

Witnesses may also have seen the other vehicle begin changing lanes or noticed the motorcycle’s approach. Preserve contact information when practical.

Passenger Witnesses Can Be Important

A passenger inside the vehicle that collided with the motorcycle may have observed the driver’s actions.

Another motorcyclist riding nearby may also have seen the collision. Witness credibility and vantage point should be considered rather than assuming any person’s account is automatically correct.

Police Reports Can Provide Useful Information

A police or CHP report may identify drivers, witnesses, vehicle damage, statements, roadway conditions, citations, and other information.

The report may describe the rider as lane splitting. That description alone does not decide civil liability.

Video, photographs, physical evidence, and witness accounts can provide additional context.

A Citation Does Not Automatically Decide Liability

A driver or rider may receive a citation following the collision.

The citation can be relevant evidence, but civil liability still requires analyzing how the conduct caused or contributed to the accident. The absence of a citation likewise does not prove that nobody acted negligently.

Preserve Motorcycle Damage

Damage to the handlebars, mirrors, fairings, foot controls, exhaust, wheels, frame, or other motorcycle components can help establish how contact occurred.

Photograph the motorcycle thoroughly before repairs. In a serious disputed collision, preservation may be important before damaged components are discarded.

Vehicle Damage Can Show the Area of Contact

Scrapes along the side of a passenger vehicle may support a sideswipe scenario, while mirror or door damage can provide additional information about the point of impact.

Damage patterns should be considered together with other evidence. They rarely answer every liability question by themselves.

Preserve the Helmet and Riding Gear

A helmet, jacket, gloves, boots, and other riding equipment can contain evidence of impact and roadway contact.

Photograph and preserve significantly damaged gear when appropriate. These items can also help document the seriousness and mechanism of the rider’s injuries.

Lane-Splitting Accidents Can Cause Serious Injuries

A rider who is struck between rows of vehicles can be knocked into another car or thrown onto the roadway.

Potential injuries include traumatic brain injuries, fractures, spinal trauma, shoulder and knee injuries, internal injuries, nerve damage, road rash, amputations, and scarring.

Learn more in Common Injuries in California Motorcycle Accident Cases.

Head Injuries Can Occur Even With a Helmet

California requires motorcycle riders and passengers to wear qualifying helmets, but protective equipment cannot prevent every brain injury.

A rider can suffer a concussion or more serious traumatic brain injury despite helmet use. Medical evaluation should be based on the rider’s symptoms and circumstances.

Learn more in California Helmet Laws and Motorcycle Accident Claims.

Road Rash Can Result From Secondary Pavement Contact

The initial vehicle contact may be relatively brief, but the rider can then slide across the roadway.

Road rash can range from superficial abrasions to deeper injuries requiring significant wound care. Photographs can document visible changes while medical records establish treatment.

Fractures Can Occur When the Rider Is Pinned Between Vehicles

Lane-splitting accidents can place the motorcycle and rider between larger vehicles.

Legs, feet, knees, hands, arms, shoulders, and other body parts may suffer direct crush or impact injuries. Complex fractures can require surgery, hardware, rehabilitation, and significant time away from work.

Seek Medical Care Based on the Actual Injury

The rider may be focused on whether the other driver improperly changed lanes and initially minimize symptoms.

Medical decisions should be based on healthcare needs rather than the liability dispute. Some concussion, neck, back, and soft-tissue symptoms may become more noticeable after the immediate stress of the accident subsides.

Preserve Medical Documentation

Keep emergency records, imaging, specialist treatment, surgery information, rehabilitation records, medication information, and medical restrictions.

These records establish the injury portion of the claim. Liability evidence separately establishes how the lane-splitting collision occurred.

Keep Records of Missed Work

A serious motorcycle injury can prevent the rider from returning to work or require modified duties.

Pay records, employer communications, schedules, medical restrictions, tax documents, and other appropriate evidence can help document accident-related income loss.

Lane Splitting Does Not Create a Standard Settlement Amount

A collision involving lane splitting is not automatically worth more or less than another motorcycle accident.

Claim value depends on the actual injuries, medical treatment, future care, lost income, permanent limitations, pain, liability, comparative fault, supporting evidence, and available insurance.

Learn more in How Much Is a California Motorcycle Accident Case Worth?.

Insurance Companies May Focus Heavily on the Rider’s Conduct

An insurer representing the other driver may argue that the motorcyclist was traveling too quickly, passing unsafely, or difficult to see.

Those arguments should be supported by evidence. The legality of lane splitting means the mere fact that the motorcycle was between lanes should not automatically establish negligence.

The Other Driver’s Conduct Must Also Be Examined

The liability investigation should consider whether the driver checked mirrors, looked over a shoulder, used a signal, moved suddenly, was distracted, or had adequate opportunity to see the motorcycle.

A rider’s conduct should not be examined in isolation while ignoring an unsafe vehicle maneuver.

Several Drivers Can Share Responsibility

A lane-splitting rider may be struck during a chain-reaction event involving several vehicles.

One driver may make an unsafe lane change while another vehicle also moves unexpectedly. California allows liability to be divided among multiple responsible parties when supported by the evidence.

Learn more in Who Is Liable in a California Motorcycle Accident?.

Commercial Vehicles Can Complicate Liability and Insurance

If a truck, bus, delivery vehicle, or other commercial vehicle strikes a lane-splitting motorcyclist, the driver’s employer and commercial insurance can potentially become relevant depending on the circumstances.

Large vehicles also have substantial blind spots and different maneuvering characteristics. Their presence does not automatically make either party responsible.

Uninsured and Underinsured Motorist Coverage May Matter

A driver who causes a lane-splitting collision may have no insurance or insufficient limits for serious motorcycle injuries.

The rider’s own UM/UIM coverage may then require evaluation. Learn more in Insurance After a Motorcycle Accident in California: What Coverage May Apply?.

Hit-and-Run Lane-Splitting Accidents Require Prompt Attention

A driver may sideswipe a motorcycle while changing lanes and continue without stopping.

Partial plates, witnesses, helmet cameras, dashcams, surveillance, paint transfer, and vehicle damage can become especially important. Unknown-driver UM claims can also involve short insurance requirements.

Learn more in Hit-and-Run Motorcycle Accidents in California.

Be Accurate When Speaking With an Insurer

An adjuster may ask how fast the motorcycle was traveling, how fast traffic was moving, where the rider was positioned, and whether the rider was lane splitting.

If you do not know an exact speed or distance, avoid guessing. Video and other evidence may provide a more reliable answer than an estimate made after a stressful accident.

Avoid Exaggerating Traffic Conditions

The difference between stopped traffic, slow traffic, and normal freeway traffic can become important.

Describe what you actually observed. Credibility can be affected when physical or video evidence later contradicts an unnecessarily precise statement.

Do Not Assume Lane Splitting Makes the Claim Weak

Some riders hesitate to pursue an accident claim because they believe lane splitting automatically places them at fault.

That is not California law. Liability depends on the actual conduct of the rider and other road users.

Do Not Assume Legal Lane Splitting Guarantees a Strong Claim Either

The opposite is also true. The fact that lane splitting is lawful does not automatically make the other driver responsible for every collision.

The rider still must have operated reasonably under the circumstances, and the other person’s negligence must be established.

Be Careful With Early Settlement Offers

An insurer may make an offer before the rider’s injuries or liability issues are fully understood.

That is not automatically inappropriate, but serious motorcycle injuries can require surgery, rehabilitation, or future treatment. Comparative-fault allegations may also require additional investigation before the value of the claim can be meaningfully assessed.

Understand a Settlement Release Before Signing

A final release can end claims against the people or entities it covers.

If several drivers, vehicle owners, employers, or policies may be involved, understand which rights are being resolved before finalizing one portion of the accident.

Evidence Can Disappear Quickly

Dashcam footage can be overwritten, surveillance can disappear, vehicles are repaired, and witnesses become harder to locate.

Lane-splitting cases can be particularly dependent on video because speed and vehicle positioning are often disputed. Evidence preservation should begin long before the legal filing deadline approaches.

Filing Deadlines Still Apply

Many ordinary California motorcycle injury lawsuits generally have a two-year filing period, while government claims, hit-and-run insurance matters, and other circumstances can involve different or much earlier requirements.

Ongoing arguments about whether the rider was lane splitting safely do not necessarily extend those deadlines.

What Evidence Can Help After a Lane-Splitting Motorcycle Accident?

Video evidence: Preserve helmet-camera footage, motorcycle cameras, dashcams, surveillance, and commercial fleet recordings that may show traffic speed, lane positions, or the driver’s movement.

Scene evidence: Photograph the lanes, lane markings, shoulder, traffic congestion, construction, roadway width, barriers, vehicle positions, and surrounding conditions.

Vehicle evidence: Document motorcycle damage, the other vehicle’s impact area, paint transfer, mirrors, doors, and other physical evidence before repairs.

Witness and police information: Preserve witness contact information, police or CHP reports, citations, and accurate statements made at the scene.

Medical and financial records: Keep treatment information, restrictions, wage documentation, and other records showing the consequences of the collision.

These categories can help establish both how the lane-splitting accident occurred and what losses resulted.

When Speaking With a California Motorcycle Accident Lawyer May Help

Not every lane-splitting motorcycle accident requires legal representation. Speaking with an attorney may be particularly useful when the injuries are serious, the driver claims the rider was traveling too fast, there is disagreement about whether the motorcycle was splitting lanes or riding on the shoulder, important video may disappear, or several drivers contributed to the collision.

A meaningful analysis should focus on what the rider was doing, what the other driver was doing, the surrounding traffic conditions, and how those actions combined to cause the crash.
