California motorcycle law has five features that create a unique liability and damages framework. First, California is the ONLY state where lane splitting is expressly legal by statute (Assembly Bill 51, Vehicle Code Section 21658.1, passed 2016). Second, Vehicle Code Section 27803 imposes a universal helmet requirement on all riders and passengers; helmet non-use is not automatic negligence but supports a comparative-fault defense for head and neck injuries. Third, Proposition 213 (Civil Code Section 3333.4) bars UNINSURED motorcyclists from recovering non-economic damages (pain and suffering) regardless of how clearly the at-fault driver was negligent. Fourth, pure comparative negligence under Civil Code Section 1714 means even a high-fault rider recovers something. Fifth, motorcycle bias on both adjuster and jury sides materially affects settlement valuation; California pure comparative does not eliminate the case but bias can reduce recovery by 10 to 30 percent according to multiple studies. Combined with no statutory cap on auto pain and suffering, the state produces some of the highest motorcycle verdicts in the country, including the $37,025,000 LaPlante San Diego County 2025 settlement and the $15,000,000 LAPD Motorcycle Sergeant 2024 settlement.
Key facts at a glance
California Motorcycle Accident Settlement Values (2026)
Last updated
- AB 51 lane splitting (VC 21658.1)
- California is the ONLY US state where lane splitting is expressly legal. CHP guidance: don't exceed traffic by more than 10 mph; don't lane split above 30 mph. Not negligence per se, but defense raises in comparative-fault analysis.
- VC 27803 universal helmet law
- All riders and passengers must wear DOT-compliant helmets regardless of age. Violation = $197 infraction. Civil case impact: helmet non-use defense requires defense to prove (analogous to CACI 712) helmet would have prevented or reduced the specific injury. Affects head/neck only; not torso or lower-extremity injuries.
- Prop 213 (Civ. Code 3333.4) BAR on uninsured motorcyclists
- Uninsured motorcyclist recovers ECONOMIC DAMAGES ONLY. No pain and suffering, no emotional distress, no loss of enjoyment of life. Major and often-overlooked feature. Exceptions: passenger, drunk driver, non-motor-vehicle defendant.
- Pure comparative (Civ. Code 1714)
- Recover damages even at 99% fault. Pure comparative under Li v. Yellow Cab Co. (1975). One of 13 pure comparative states.
- Motorcycle bias
- Adjusters and juries assign 10-30% more fault to motorcyclists than to car drivers in similar scenarios per studies. Public perception assumes rider negligence even though car drivers are at fault ~60% in two-vehicle crashes.
- CA motorcycle fatalities + LA dominance
- 583 motorcyclist deaths in 2023; average 500-550/year. Riders 28x more likely to die than car occupants per VMT. LA County leads all California venues; nearly 3x more motorcycle fatalities than San Diego (next closest).

How Much to Expect From a Motorcycle Accident Settlement in California
California motorcycle settlements span from $10,000 for minor road rash to over $37 million for catastrophic injury and wrongful death. The state's pure comparative regime, the absence of any statutory cap on auto pain and suffering, and the largest plaintiff-friendly jury pools in the country combine to produce some of the highest motorcycle verdicts in the US. Counterweights: Prop 213 (which bars non-economic damages for uninsured riders), motorcycle bias (which compresses recovery by 10 to 30 percent), and helmet-defense allocation for head-injury cases.
Cited representative California motorcycle outcomes include:
- • $37,025,000 Michael LaPlante v. Griffith Company (San Diego County, May 2025). 42-year-old motorcyclist on SR-94. Construction-company truck driver made unsafe U-turn into rider's path. Multiple rib fractures, kidney injury, hip fracture, femoral artery injury, open tibia/fibula fractures, talus fracture, labral tears, eventual left leg amputation after 18 surgeries. High/low agreement $37,025,000 low / $42M high; jury verdict $27,727,630; fault allocation Griffith 80% / driver 20%.
- • $15,000,000 LAPD Motorcycle Sergeant 2024 settlement against the City of Inglewood. Sergeant on motorcycle in driveway at USC entrance; Inglewood Mayor James Butts' vehicle collided with a speeding motorist and struck the officer. Mild TBI plus aggravation of pre-existing workers' comp injuries; officer thrown into adjacent fountain.
- • $11,800,000 Julian Gonzalez verdict by Dolan Law Firm in 2024.
- • $11,045,000 Grady Dillon jury verdict at LA County Superior Court (Van Nuys) against the Los Angeles Department of Water and Power vehicle.

- • $500,000 surgical ankle fracture (left-turn collision, policy limits, Sally Morin Law).
AB 51 Lane Splitting (Vehicle Code Section 21658.1)
California is the only state in the United States where lane splitting is expressly legal by statute. Assembly Bill 51, signed in 2016, added Vehicle Code Section 21658.1 and defined 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, including on both divided and undivided streets, roads, and highways. AB 51 also authorized the California Highway Patrol to develop educational guidelines.
CHP Lane Splitting Safety Guidance
- • Do not exceed the speed of traffic by more than 10 mph
- • Do not lane split at speeds exceeding 30 mph
- • Lane splitting is safer when traffic is moving at 30 mph or less
- • Consider total environment: lane width, surrounding vehicle size, roadway conditions
- • Lane splitting at night, in rain, or in fog increases risk significantly
Why AB 51 Matters for Your Civil Case
Lane splitting itself is NOT negligence per se. The defense cannot argue that the act of lane splitting alone establishes the motorcyclist's fault. However, lane splitting performed in an unsafe or reckless manner (excessive speed differential, unsafe gap, weaving, late signaling) can support comparative-fault arguments under Civil Code Section 1714 and can also result in citations under other Vehicle Code sections (basic speed law VC 22350, reckless driving VC 23103).
Lock In Lane-Splitting Speed and Gap Data Early
VC 27803 Universal Helmet Law (and the Civil Case Helmet Defense)
California has a universal helmet law under Vehicle Code Section 27803. All riders and passengers, regardless of age or experience, must wear DOT-compliant helmets on motorcycles, motorized bicycles, and motor-driven cycles. Violation is an infraction with a $197 fine.
The Statutory Rule (VC 27803)
A driver and any passenger shall wear a safety helmet meeting federal motor vehicle safety standards (FMVSS 218) when operating or riding on a motorcycle, motor-driven cycle, or motorized bicycle. The helmet must be fastened with the chinstrap.
Civil Case Impact: The Helmet Defense
Unlike Vehicle Code Section 27315(i) (which explicitly states that a seat-belt violation does not by itself prove negligence), there is no parallel statutory exclusion for helmets. The defense therefore raises helmet non-use as a comparative-fault and mitigation-of-damages argument under Civil Code Section 1714 and related doctrine.
Defense Burden (Analogous to CACI 712)
The defense must prove three elements: (1) a DOT-compliant helmet was available; (2) a reasonably careful person would have worn it; (3) the helmet would have avoided or significantly reduced the specific injuries. Biomechanical expert testimony is typically required to establish element (3).
The Helmet Defense Affects Damages Only for Head and Neck Injuries
The helmet defense is narrow. It cannot reduce damages for injuries a helmet could not have prevented:
- • Affected by helmet defense: traumatic brain injury, skull fracture, facial fractures, cervical spine injuries, concussion (depending on biomechanics)
- • NOT affected by helmet defense: leg and ankle fractures, pelvic fractures, road rash on torso/limbs, internal organ damage, lumbar spine injuries, shoulder injuries
NHTSA data: helmets reduce head trauma risk by 69 percent and fatal-crash risk by 37 percent. The defense lever is real but limited to head/neck injury categories; lower-extremity and torso injuries are recoverable in full regardless of helmet status.
Proposition 213: The Uninsured-Rider Bar on Non-Economic Damages
Proposition 213 (codified at Civil Code Section 3333.4, the Personal Responsibility Act of 1996) is one of the most important and most misunderstood features of California motorcycle law. Prop 213 bars the OPERATOR of an uninsured motor vehicle from recovering non-economic damages (pain and suffering, emotional distress, loss of enjoyment of life) in any auto-related action.
Critical: Prop 213 APPLIES to Motorcycle Riders
Motorcycle riders ARE operators of motor vehicles under California law. An uninsured motorcyclist struck by a fully insured at-fault driver can recover ECONOMIC damages only (medical bills, lost wages, property damage) and is BARRED from non-economic damages.
Non-economic damages are typically 50 to 80 percent of the total recovery in a serious motorcycle case. Losing the pain-and-suffering component can reduce a $1,000,000 case to $200,000 in pure economic damages.
Exceptions Where Prop 213 Does NOT Apply
- • Motorcycle passenger (not the operator) is not barred
- • At-fault driver was drunk (DUI exception under Civ. Code 3333.4(c))
- • Claim against a non-motor-vehicle defendant (premises liability, defective product, dangerous-roadway claim against public entity)
- • Pedestrian status at time of injury (Prop 213 does not apply to pedestrian claims even if the claimant owns an uninsured vehicle)
Always Verify Motorcycle Insurance Status on the Crash Date
Pure Comparative Negligence Under Civil Code Section 1714
California is one of only 13 pure comparative negligence states. The doctrine was adopted by the California Supreme Court in Li v. Yellow Cab Co. (1975) and is rooted in Civil Code Section 1714.
What Pure Comparative Means in Motorcycle Cases
- • You recover damages even at 99 percent fault. Award reduced by your share, never eliminated.
- • A motorcyclist assigned 40 percent fault (lane-splitting comparative defense) with $600,000 in damages recovers $360,000.
- • A motorcyclist assigned 70 percent fault (no helmet + speeding) with $500,000 in damages still recovers $150,000.
- • The 'last clear chance' doctrine merged into comparative-fault analysis.
How CA Compares to Other State Regimes for Motorcycle Cases
| State Regime | Bar Threshold | Motorcyclist at 50% Fault, $400K Damages |
|---|---|---|
| California (pure comparative) | None | Recovers $200,000 |
| Washington (pure comparative) | None | Recovers $200,000 |
| Arizona (pure comparative) | None | Recovers $200,000 |
| Colorado (modified, 50% BAR) | 50% | Recovers $0 |
| Texas (modified, 51% bar) | 51% | Recovers $200,000 |
| Maryland (contributory) | Any fault | Recovers $0 |
California's pure comparative regime is critical for motorcycle cases because motorcycle bias frequently produces fault allocations in the 30 to 50 percent range against the rider. In a modified-comparative state, those same fault percentages would kill the case at the 50 percent bar; in California, even a heavily-disputed case still produces meaningful recovery.
Motorcycle Bias: The Adjuster and Jury Problem
Motorcycle bias is the documented tendency of jurors, insurance adjusters, and occasionally judges to assume motorcyclists are reckless thrill-seekers who bear partial responsibility for their own injuries, regardless of the actual facts. The bias starts in adjuster offices (early settlement-offer anchoring) and follows the case into trial (jury fault-allocation adjustments).
Documented Bias Impact
- • Studies show juries assign 10 to 30 percent more fault to motorcyclists than to car drivers in identical accident scenarios
- • In two-vehicle motorcycle-versus-car crashes, the car driver is at fault approximately 60 percent of the time, but public perception assumes the opposite
- • Defense lawyers exploit bias by emphasizing speed, lane-splitting, helmet questions, biker stereotype, and 'sportbike' versus 'cruiser' framing
- • Insurance adjusters anchor early settlement offers low based on assumed bias outcomes at trial
How to Counteract Motorcycle Bias
- • Verify and document the rider's M1 motorcycle license (required under Vehicle Code Section 12804.9)
- • Pull a clean DMV record showing no prior moving violations
- • Document completion of a CHP California Motorcyclist Safety Program (CMSP) course; the course waives the DMV driving test and demonstrates training
- • Preserve the helmet and protective gear (jacket, gloves, boots) to demonstrate the rider was equipped for safety
- • Establish the rider's professional background (LAPD officer, engineer, etc.) to humanize and credential the plaintiff
- • Frame the case around the at-fault driver's specific negligent behavior (texting, drinking, illegal turn, speed) rather than letting defense reframe as 'biker case'
- • Use voir dire to identify jurors with anti-motorcycle bias and exercise peremptory challenges
Who Pays Your Medical Bills as a CA Motorcyclist (No PIP)
California is a tort state with no PIP no-fault coverage. Medical bills for an injured motorcyclist stack through five layers. Motorcycle injuries are often catastrophic (open fractures, surgical orthopedic, TBI), so planning the coverage stack early is critical.
Medical Coverage Stack for a CA Motorcyclist
- Your own health insurance: Primary first-dollar payer. Subject to deductibles, copays, and subrogation against the eventual tort recovery (subject to the Made Whole Doctrine).
- MedPay on your own motorcycle policy (if carried): Motorcycle MedPay availability is restricted compared to auto MedPay. Typical limits $1,000 to $25,000. Verify your specific policy because some carriers exclude motorcycles or restrict MedPay. MedPay follows the rider and pays without regard to fault.
- Hospital and provider medical liens: Providers treat now and recoup from settlement. California Hospital Lien Act (Civ. Code Section 3045.1 et seq.) caps hospital lien recovery at 50 percent of net (after attorney fees).
- At-fault driver's bodily injury policy: California auto minimum 30/60/15 effective January 1, 2025 under SB 1107 (from prior 15/30/5). Motorcycle minimums historically 15/30/5; verify with carrier. Pays at the end as part of the third-party settlement.
- Your own UM/UIM coverage: Mandatory offer under Insurance Code Section 11580.2 unless waived in writing. UM/UIM follows the rider and covers the gap when the at-fault driver has no or insufficient coverage. Critical for motorcycle cases because of frequent injury severity.
UM/UIM Is Doubly Critical for Motorcyclists
Public-Entity Vehicles and the 6-Month Government Claims Act Deadline
Under the California Government Claims Act (Government Code Section 911.2), a written claim must be presented to the public entity within 6 MONTHS of the date of injury for any personal injury claim against a public-entity vehicle.
- • LADOT, LA Metro buses, LADWP vehicles, LA County Sheriff vehicles
- • San Francisco Muni vehicles, SFPD vehicles, SFFD vehicles
- • School district vehicles (school buses, district vans)
- • California Highway Patrol vehicles (including CHP motorcycles)
- • Caltrans vehicles and roadway-design defect claims
- • City, county, and state-agency vehicles of any kind
Public-Entity Motorcycle Cases Have Produced Very High Recoveries
- • $15,000,000 LAPD Motorcycle Sergeant 2024 settlement (Inglewood city-vehicle defendant)
- • $11,045,000 Grady Dillon jury verdict at LA Superior Court Van Nuys vs. Los Angeles Department of Water and Power vehicle
- • $37,025,000 LaPlante San Diego County 2025 high/low settlement against construction-company commercial defendant
The public entity has 45 days to act on the claim; if it rejects, you have 6 months from rejection to file the lawsuit. The 2-year CCP 335.1 SOL is overridden by the shorter claim-rejection clock. Late-claim relief under Gov. Code 911.4 within 1 year of accrual is discretionary and frequently denied.
Most Common California Motorcycle Crash Types
Three crash patterns dominate California motorcycle cases. Understanding the dominant pattern in your specific case shapes the liability theory and comparative-fault analysis.
Left-Turn Collisions (42% of motorcycle crashes; 36% of fatalities)
Per a 2023 Berkeley SafeTREC study, approximately 42 percent of motorcycle crashes involve another driver failing to detect the motorcycle during a left turn. Left-turn crashes account for approximately 36 percent of motorcycle fatalities. The typical pattern: a car making a left turn at an intersection or driveway turns across the path of an oncoming motorcycle. The car driver later claims 'I never saw the motorcycle' (the inattentional- blindness defense). Liability is typically clear under Vehicle Code Section 21801 (duty to yield when making a left turn).
Rear-End Collisions
Vehicle Code Section 21703 (following too closely) creates a presumption of negligence against the rear-ending driver. Common during freeway congestion where a car driver fails to leave adequate following distance behind a motorcycle. Also common during lane splitting in slow-or-stopped traffic; if the rider rear-ends a vehicle while lane splitting at excessive speed, comparative fault can be assigned.
Lane-Change Collisions
A car driver changes lanes without checking the adjacent lane for a motorcycle. Vehicle Code Section 22107 requires safe lane changes with proper signaling. The 'sudden movement' defense (motorcycle emerged suddenly) is common and is counteracted with reconstruction expert testimony, dash-cam, and traffic-camera evidence.
Construction-Zone and Commercial-Vehicle Collisions
The $37,025,000 LaPlante San Diego County case (2025) is the signature recent example: construction-truck driver made unsafe U-turn on SR-94 into oncoming motorcyclist's path. Commercial defendants (construction companies, trucking fleets, public-entity vehicles) have higher policy limits plus umbrella excess plus potential direct-negligence claims (negligent training, negligent supervision, unsafe policies).
California's Deadliest Motorcycle Corridors
California recorded approximately 583 motorcyclist deaths in 2023 (down 10.2 percent from 649 in 2022 but up nearly 19 percent from 491 in 2019). The state averages 500 to 550 motorcyclist deaths per year. LA County leads all California venues with nearly 3 times the motorcycle fatality count of San Diego.
Los Angeles Freeways (Highest Concentration)
- • I-405: 189 motorcycle injury crashes in 2025 with 4 fatalities; a short 5.76-mile segment has produced multiple fatalities
- • I-5: 128 serious motorcycle crashes in 2025; California's deadliest highway overall (128 lives lost in 2022)
- • US-101: high-density congestion makes it one of the most hazardous roads in LA for motorcyclists
- • I-10 and I-110: also produce significant motorcycle fatality counts
Mountain and Coastal Recreational Routes
Approximately 60 percent of fatal motorcycle crashes occur on non-interstate roads. Dangerous CA recreational routes include the Pacific Coast Highway (Highway 1) through the Malibu canyons (weekend-rider route with sharp curves and limited sight lines), Highway 1 through Big Sur, the Angeles Crest Highway (notorious for sportbike crashes), Highway 33 / Highway 150 in Ventura County, and Highway 49 in the Sierra foothills.
Crash Causes Statewide
- • Speeding contributes to approximately 33 percent of fatal motorcycle crashes
- • Alcohol impairment is involved in approximately 25 percent of rider deaths
- • Nighttime riding increases fatal crash risk by roughly 30 percent
- • Approximately 14 percent of all California traffic fatalities involve a motorcyclist
Use SWITRS and UC Berkeley TIMS for Strike-Location Data
The Statewide Integrated Traffic Records System (SWITRS) is California's master crash database. UC Berkeley SafeTREC maintains the TIMS dashboard at tims.berkeley.edu, which maps every prior crash at an intersection or freeway segment. Prior crashes at the strike location support a foreseeability argument against Caltrans or other public-entity defendants in dangerous-roadway- design claims.
California Motorcycle Settlement Ranges by Injury Type
California motorcycle settlement ranges benefit from no statutory caps, pure comparative negligence, and large plaintiff-friendly jury pools. Catastrophic-injury cases against commercial defendants with umbrella excess produce eight-figure outcomes. The Prop 213 bar and motorcycle bias compress the upside in disputed-liability or uninsured-rider cases.
| Injury Type | CA Motorcycle Range | Notes |
|---|---|---|
| Road rash / abrasion only | $10,000 - $50,000 | Minor abrasions; partial-thickness skin loss at upper end with skin graft |
| Wrist / hand / clavicle fracture | $50,000 - $250,000 | Common from fall-arrest reflex; ORIF surgical at upper end |
| Tibia / fibula / ankle fracture | $150,000 - $750,000 | $500K cited (left-turn ankle ORIF, policy limits); helmet defense does not apply |
| Pelvic / femur fracture | $250,000 - $1,500,000 | Surgical; long-term gait limitation common |
| Herniated disc / spinal (non-cord) | $200,000 - $1,500,000 | Surgical cases (microdiscectomy, fusion) at upper end |
| Traumatic Brain Injury (TBI) | $500,000 - $15,000,000+ | $15M LAPD sergeant 2024 cited; helmet defense applies (head/neck only) |
| Amputation (limb) | $3,000,000 - $37,000,000+ | $37M LaPlante 2025 cited (leg amputation after 18 surgeries); helmet defense does not apply |
| Spinal cord injury / paraplegia | $5,000,000 - $30,000,000+ | Catastrophic; lifetime care drives economic damages; no statutory cap |
| Wrongful death | $1,250,000 - $15,000,000+ | $6.225M farm-tractor cited; $1.25M left-turn hit-and-run policy limits; no statutory cap on auto wrongful death |
Source: SetCalc analysis of California motorcycle settlement data, 2021 to 2026. Cited verdicts: $37,025,000 LaPlante v. Griffith Co. (San Diego County 2025, leg amputation); $15M LAPD Sergeant 2024 (Inglewood); $11.8M Gonzalez 2024 (Dolan); $11,045,000 Dillon 2024 (LADWP, Van Nuys); $6,225,000 wrongful death farm tractor; $4,725,000 LA Hillstone; $3.8M cement company; $1.75M Livermore; $1.25M left-turn fatal hit-and-run policy limits; $830K Alameda lane-splitting; $500K left-turn ankle surgical. Prop 213 reduces economic-only recovery materially in uninsured rider cases.
How to Maximize Your California Motorcycle Settlement
Five steps tailored to California motorcycle cases. Each addresses a CA- specific lever: public-entity 6-month notice, the AB 51 / VC 27803 / Prop 213 statutory framework, motorcycle bias neutralization, and the medical coverage stack.
Identify the At-Fault Driver, the Insurance Stack, and Public-Entity Defendants Within Days
Photograph plates and policy declarations. If a public-entity vehicle (LADOT, LA Metro, school bus, CHP, Caltrans, LADWP, etc.) was involved OR a dangerous-condition claim against a public entity exists, file the 6-month Gov. Code 911.2 notice. The 2-year CCP 335.1 SOL does not override the 6-month deadline. Investigate commercial-vehicle umbrella excess (the LaPlante case found $37M in available coverage above $1M primary).
Key point: Late-claim relief under Gov. Code 911.4 within 1 year of accrual is discretionary and frequently denied.
Demand the TCR, MAIT Report, and Any Vehicle Code Citation
The CHP-555 or local police TCR contains the officer's fault analysis. For left-turn cases, look for VC 21801; for rear-end, VC 21703 (with presumption of negligence); for unsafe lane change, VC 22107. Subpoena body-cam, dash-cam, 911 audio, and witness statements. For fatal or major-injury crashes investigated by CHP, the MAIT (Multidisciplinary Accident Investigation Team) report is the most thorough and almost always supports the motorcyclist.
Key point: Vehicle Code violations support negligence per se under Evidence Code 669 and CACI 418. A VC 21801 citation against a left-turning driver is gold.
Neutralize Motorcycle Bias and the Helmet Defense
Document the rider's M1 license and CHP California Motorcyclist Safety Program (CMSP) completion. Pull a clean DMV record. Preserve the DOT-compliant helmet if worn. If no helmet, evaluate which specific injuries the defense can credibly tie to non-helmet use (head/neck only). Frame the case as 'distracted/impaired car driver hit motorcyclist with the right of way' rather than letting defense reframe as 'biker case.' Use voir dire to identify anti-motorcycle jurors.
Key point: The helmet defense affects head/neck injuries only; torso and lower-extremity damages are recoverable in full regardless of helmet status.
Handle Prop 213 and Lane Splitting Carefully
Verify motorcycle insurance status on the crash date. If uninsured, Prop 213 bars non-economic damages. Exceptions: passenger, DUI driver, non-motor-vehicle defendant. If lane splitting at impact, collect ECU speed log, dash-cam, surveillance, and traffic-camera footage to demonstrate compliance with the CHP guidelines (under 30 mph absolute, under 10 mph differential vs. traffic).
Key point: A few days of lapsed coverage can trigger Prop 213. Always request the carrier's declaration page and policy-in- force documentation as part of the first-week case workup.
Stack Health Insurance, MedPay, Liens, and UM/UIM
No PIP. Stack: health insurance + MedPay (if motorcycle policy includes it, typical $1K-$25K) + hospital and provider liens (50% statutory cap on net) + at-fault BI + your own UM/UIM (mandatory offer under Insurance Code 11580.2 unless waived in writing). UM/UIM follows the rider. Critical because motorcycle injuries routinely exceed minimum BI policies.

California Motorcycle Settlement Examples
Five California motorcycle scenarios calibrated to the available liability stack, the AB 51 / VC 27803 / Prop 213 framework, motorcycle bias, and the venue.
Example 1: LaPlante v. Griffith Co. - San Diego SR-94 U-Turn (Cited Verdict)
Case Details:
- 42-year-old motorcyclist Michael LaPlante on SR-94
- August 27, 2021 crash; verdict May 2025
- Antelmo Martinez (Griffith Co. employee) made unsafe U-turn
- Multiple rib fractures + kidney injury + hip fracture + femoral artery + open tibia/fibula + talus + labral tears
- Left leg amputation (Nov 2021, after 18 surgeries)
- San Diego County Superior Court; Judge Timothy B. Taylor
Outcome:
- Settlement: $37,025,000
- High/low agreement $37,025,000 low / $42M high
- Jury verdict $27,727,630 (reached minutes before settlement)
- Fault: Griffith 80% / Martinez 20%
- $18,000,000 past and future pain and suffering
Cited Verdict:
$37,025,000
Commercial-defendant case with substantial coverage; catastrophic injury (amputation); helmet defense does not apply to lower-extremity injuries; pure comparative + no caps + plaintiff-friendly San Diego County venue.
Example 2: LAPD Motorcycle Sergeant vs. Inglewood Mayor (Cited Settlement)
Case Details:
- LAPD Motorcycle Sergeant on motor detail at USC driveway entrance
- Inglewood Mayor James Butts' vehicle collided with speeding motorist
- Mayor's vehicle struck the officer's motorcycle
- Officer thrown into adjacent fountain
- Mild TBI despite helmet + aggravation of pre-existing comp injuries
- Public-entity defendant (City of Inglewood)
- 6-month Gov. Code 911.2 claim filed
Outcome:
- Settlement (2024): $15,000,000
- Defense argued TBI should resolve in 90 days
- Defense argued plaintiff violated vehicle codes
- Defense argued injuries pre-existing
- Settled shortly before trial
Cited Settlement:
$15,000,000
Public-entity defendant; LAPD officer (professional plaintiff helps neutralize motorcycle bias); TBI with cognitive deficit despite helmet (helmet did not foreclose recovery); 6-month CGCA notice timely filed.
Example 3: Left-Turn Surgical Ankle Case (Sally Morin Cited Settlement)
Case Details:
- Motorcyclist with right of way on California roadway
- Car turned left in front of rider
- Rider ejected from motorcycle
- Fractured ankle requiring surgical internal fixation hardware
- VC 21801 negligence per se against turning driver
- Helmet defense does not apply (ankle injury)
- 0% comparative fault (rider had right of way)
Outcome:
- Settlement: $500,000 (policy limits)
- At-fault driver's auto liability exhausted
- UM/UIM did not apply (driver had adequate primary)
Cited Settlement:
$500,000
Classic left-turn fact pattern (42% of CA motorcycle crashes per SafeTREC); negligence per se against turning driver under VC 21801; surgical orthopedic injury justifies policy exhaustion.
Example 4: Lane-Splitting at 25 MPH in I-405 Slow Traffic (Hypothetical)
Case Details:
- Rider lane splitting at 25 mph in I-405 slow traffic (15 mph)
- Speed differential: 10 mph (CHP guideline compliant)
- Car driver unexpectedly changed lanes without signaling
- Tibial plateau fracture (ORIF surgical) + concussion
- Medical bills: $185,000; Lost wages: $48,000
- Rider had DOT helmet, M1 license, CMSP course
- VC 22107 violation against lane-changing driver
Settlement Breakdown:
- Gross damages: $675,000 (3x P&S multiplier)
- Comparative fault: 15% (lane splitting in moving traffic)
- Net recovery: $573,750
- Less hospital lien (50% net cap): $93,750
Estimated Range:
$425,000 - $575,000
AB 51 makes lane splitting legal; CHP-compliant speed differential limits comparative fault to ~15%; M1 + CMSP + DOT helmet neutralizes motorcycle bias; VC 22107 against lane-changing driver supports negligence per se.
Example 5: Uninsured Motorcyclist + Drunk At-Fault Driver (Prop 213 DUI Exception)
Case Details:
- Motorcycle policy lapsed 2 weeks before crash (uninsured)
- At-fault driver convicted of VC 23152 DUI
- Rider sustained pelvic fracture + L4-L5 herniation requiring microdiscectomy
- Medical bills: $245,000; Lost wages: $85,000
- Prop 213 DUI exception under Civ. Code 3333.4(c) applies
- Non-economic damages recoverable despite uninsured status
Settlement Breakdown:
- Economic damages: $330,000
- Non-economic damages: $720,000 (3x multiplier, DUI exception applies)
- Gross damages: $1,050,000
- 0% comparative fault (rider had right of way)
Estimated Range:
$750,000 - $1,050,000
Without DUI exception, Prop 213 would have barred non-economic damages and reduced recovery to ~$330K economic only. DUI conviction unlocks the full case value despite uninsured-motorcycle status.
