Accidents move fast. This guide doesn't. Every step below is attorney-reviewed, specific to Los Angeles, California law, and written in plain language instead of legal jargon — with each answer linked to its source, so you don't miss what matters.
This guide applies to California law only. Laws in other states differ significantly. Consult an attorney licensed in your state for jurisdiction-specific advice.
If you were injured in a motorcycle accident in Los Angeles, lane splitting is fully legal under CVC § 21658.1: California is the only state where this applies.
- Helmet law: Helmets are mandatory under CVC § 27803, riding without one can reduce head injury damages but does not eliminate your claim
- Comparative fault: California's pure comparative negligence rule allows recovery at any fault percentage
- Statute of limitations: 2 years under CCP § 335.1
- Preserve your helmet and gear, damage patterns are forensic evidence for reconstruction experts
California recorded 583 motorcyclist fatalities in 2023, according to California OTS. Insurers routinely argue rider fault to suppress settlement values in motorcycle cases.
Contact a motorcycle accident attorney before accepting any liability assessment from the opposing insurer.

Step 1: Select accident type
What type of accident were you in?
Right now · first hours
At the scene
Medical first. Concussion, TBI, and internal injuries can surface hours after a crash. A worsening headache, confusion, repeated vomiting, or numbness means emergency care now (CDC head-injury danger signs).
- 1
Call 911. California requires a police report for any accident with injury. Do not move your motorcycle unless it is blocking traffic and you are physically able; the post-impact position is critical evidence for reconstruction.
- 2
Preserve your helmet and all protective gear at the scene. Photograph the damage to both the motorcycle and the other vehicle(s), road conditions, lane markings, and skid marks. If you were lane splitting, photograph the lane widths and traffic density from the scene.
- 3
Get witness contact information. Fault disputes are routine in motorcycle cases, and witnesses who saw the other driver's behavior are invaluable.
Do not
- ✕Describe your lane position at the scene beyond what is required for the police report. Any admission that you were splitting, regardless of whether it caused the crash, will be used by the insurer to assign a comparative fault percentage.
- ✕Clean or repair your helmet. Its post-crash condition is forensic evidence for impact severity and angle.
First 72 hours
Report & preserve evidence
Defense adjusters in LA motorcycle cases almost always raise the same arguments: you were speeding, your lane position was unsafe, or your helmet was non-compliant. The first 72 hours is when you collect what negates those claims before the insurer's narrative is set.
- Preserve the other driver's phone records within 30 days. California Vehicle Code § 23123.5 prohibits handheld phone use while driving. Cell records subpoenaed through litigation discovery show whether the driver was texting at impact. A litigation hold demand must be sent before records are deleted.
- Preserve dashcam footage from the bike, witness statements, and scene photos. This documentation defeats the standard fault-inflation arguments.
- See a doctor immediately. Motorcycle crashes produce road rash, orthopedic damage, and TBI that may not present full symptoms for 24 to 72 hours. A same-day medical record anchors injury causation.
Why a motorcycle crash is different
California law gives riders a unique legal advantage on lane splitting, but also imposes helmet compliance as a potential fault argument. Three points drive almost every LA motorcycle defense:
- Lane splitting is legal in California. CVC § 21658.1 explicitly permits lane splitting. California is the only US state where this applies. Splitting in compliance with CHP guidelines does not constitute negligence and cannot eliminate your claim.
- Helmets are required. CVC § 27803 mandates DOT-approved helmets. Non-compliance can be raised as comparative fault for head injuries specifically; it does not reduce non-head injury damages.
- Injury severity changes the math. Motorcycle crashes produce road rash requiring skin grafts, orthopedic damage, and TBI that routinely justify 5x to 15x+ medical cost multipliers. Insurers routinely apply car-accident multipliers (1.5x to 3x) to motorcycle cases by default.
- Left-turn crashes. Under CVC § 21801, left-turning vehicles that strike an oncoming motorcycle are presumed at fault for failure to yield. This is the most common crash pattern.
California recorded 583 motorcyclist fatalities in 2023, one of the highest totals of any US state, with Los Angeles County accounting for the largest share.
The I-405, I-10, US-101, and PCH corridors are the most dangerous motorcycle routes in greater Los Angeles due to high vehicle speeds, lane density, and driver inattention.

First 2 weeks · before you sign
Protect the claim before you sign anything
- Insist on functional-limitation documentation, not just pain notes. Documented permanent impairment and restrictions are what establish full damages and justify high multipliers when the insurer disputes them.
- Do not sign a release before your prognosis is complete. Comparative-fault arguments suppress early offers; a complete medical record anchored to a specific impairment rating restores them.
A quick settlement offer is information to weigh against your full and future costs, not something this page can tell you to accept or reject. The correct moment to evaluate any offer is after you reach Maximum Medical Improvement (MMI) and understand all future care costs. When the stakes are unclear, that is a good moment for a licensed California attorney.

When you want a verified local attorney
Motorcycle cases are won by anticipating the three standard defense arguments before the insurer makes them, and by applying the right injury multiplier to a severity profile that adjusters routinely undervalue.

- 2 years from the crash for most California personal injury lawsuits (CCP § 335.1). Missing this date permanently bars your claim.
- 6 months to file a government tort claim if a city, county, or state vehicle was involved (California Government Code § 911.2). This is a hard deadline courts almost never extend.
- 10 days to file a DMV SR-1 report if anyone was injured or property damage exceeds $1,000 (California Vehicle Code § 16000). Failure can result in license suspension.
- Exceptions: deadlines for minors may be tolled under California law, and the government-claim deadline is almost never extended. The discovery rule can delay the 2-year clock for late-onset injuries. Verify your specific situation with a licensed California attorney.
Frequently Asked Questions
Is lane splitting legal in California?▼
Yes. California is the only US state where lane splitting is explicitly legal under Vehicle Code § 21658.1, effective January 1, 2017. CHP guidelines recommend splitting only when surrounding traffic is moving at 30 mph or slower and at no more than 10 mph faster than traffic. Lane splitting in compliance with CHP guidelines does not constitute negligence and cannot be used to reduce your damages under comparative negligence.
Can I still recover damages if I wasn't wearing a helmet in California?▼
Yes, but your damages may be reduced. California's mandatory helmet law (Vehicle Code § 27803) requires DOT-approved helmets. Under Pure Comparative Negligence, the at-fault driver's insurer can argue that your head injuries were more severe because you were not wearing a helmet, this reduces the head-injury portion of your damages proportionally. However, it does not eliminate your claim entirely, and it does not reduce damages for non-head injuries (broken bones, internal injuries, road rash).
What if the other driver says I was lane splitting when I wasn't?▼
This is the most common false defense in California motorcycle cases. Your attorney should obtain surveillance footage from nearby businesses and traffic cameras, the other driver's dashcam footage, and accident scene evidence (scrape marks, debris patterns, point of impact on both vehicles) to disprove the claim. Accident reconstruction experts can determine the exact pre-impact positions of both vehicles.
Who is at fault in a left-turn motorcycle accident in California?▼
In the majority of car-versus-motorcycle collisions, the car driver is at fault for failing to yield. Left-turning vehicles that strike an oncoming motorcycle are presumed at fault under California Vehicle Code § 21801 (failure to yield during left turn). The only exception is if the motorcycle was significantly exceeding the speed limit or running a red light, and even then, California's Pure Comparative Negligence rule allows partial recovery.
How long do I have to file a motorcycle accident claim in California?▼
2 years from the accident date under CCP § 335.1. If the at-fault driver was a government employee in a government vehicle, you may have as little as 6 months to file a government tort claim under California Government Code § 911.2. Contact a crash specialist immediately if a government vehicle was involved.
Does California's comparative negligence rule affect my motorcycle claim?▼
Yes, and it works in your favor. California follows Pure Comparative Negligence, which means you recover damages proportional to the other party's fault, even if you were more than 50% at fault (unlike modified comparative negligence states that bar recovery above 50%). If you were 40% at fault for speeding and the driver was 60% at fault for not checking mirrors, you recover 60% of your full damages.
Can I recover damages for road rash and motorcycle damage in California?▼
Yes. Road rash requiring skin grafts, scarring treatment, and infection care is a fully recoverable injury. California courts award non-economic damages for permanent scarring under Pure Comparative Negligence. Your motorcycle, protective gear, and riding apparel are covered as property damage. Photograph all gear before discarding, damaged equipment establishes crash severity and supports injury claims.
What if the driver who hit me was distracted. Can I prove phone use?▼
Yes. Cell phone records subpoenaed through litigation discovery show whether the driver was texting, calling, or using navigation at impact. California Vehicle Code § 23123.5 prohibits handheld phone use while driving, a violation establishes negligence per se. Your attorney must issue a litigation hold demand within 30 days before records are deleted.
