Motorcyclists are among the most vulnerable people on San Francisco’s roads. When a collision occurs, riders face catastrophic injuries — often life-altering — while insurance companies work aggressively to minimize or deny claims. You need an experienced trial attorney in your corner.
I represent injured motorcyclists throughout San Francisco and the Bay Area. I have recovered over $25 million for injured clients and fight hard against insurance companies for maximum compensation. Free consultation. No fee unless I win. Representation is available in English or Spanish — I am a bilingual personal injury lawyer and conduct full representation in either language without an interpreter.
Why Motorcycle Accidents Are So Devastating
Unlike car occupants, motorcyclists have no protective shell around them. Even at moderate speeds, a collision can result in traumatic brain injuries, spinal cord damage, road rash, fractures, and internal injuries. According to the California Office of Traffic Safety, motorcyclists are approximately 29 times more likely to die in a crash than passenger car occupants per mile traveled.
Motorcycle riders who suffer head trauma are at serious risk of a subdural hematoma, even when wearing a helmet.
San Francisco’s unique road conditions — steep hills, foggy intersections, heavy rideshare and delivery traffic, and dense pedestrian activity — make riding here particularly dangerous.
The injury pattern in a motorcycle collision is different in kind, not just in degree. A rider thrown from the bike absorbs the impact twice — once at the point of collision, once at the point of landing — and the second impact is frequently the one that causes the traumatic brain injury or the spinal fracture. That is why a rider wearing a helmet can still walk away from the scene, decline the ambulance, and be in an emergency room forty-eight hours later with a subdural hematoma nobody caught.
California requires every motorcycle rider and passenger to wear a U.S. DOT-compliant helmet under Vehicle Code section 27803. That requirement cuts both ways in a claim. If you were wearing a helmet, expect the insurer to argue that your head injury cannot be as serious as you say. If you were not, expect an aggressive comparative-fault argument. Neither argument is automatically correct, and neither one is a reason to accept a low offer.
Common Causes of Motorcycle Accidents in San Francisco
- Drivers failing to see motorcycles and making left turns into their path
- Lane change collisions — drivers merging without checking blind spots
- Rear-end collisions at stop lights on Market Street, Van Ness, and Geary
- Rideshare and delivery vehicles making sudden stops or illegal turns
- Dooring — a driver opens their car door into a motorcyclist’s path
- Speeding drivers on US-101 and I-280
- Dangerous road conditions including potholes, wet pavement, and debris
- Drunk or distracted driving
Common Injuries in San Francisco Motorcycle Accidents
Motorcyclists suffer some of the most severe injuries seen in personal injury cases because there is nothing between the rider and the road:
Traumatic Brain Injury Even helmeted riders can suffer TBI in high-speed collisions or when the impact involves rotational force. TBI is the leading cause of motorcycle fatality and long-term disability. I have secured $6,000,000 and $2,185,000 for TBI victims in San Francisco.
Road Rash Sliding across pavement at speed causes deep tissue injuries that can require skin grafting, leave permanent scarring, and carry serious infection risk. Severe road rash is often undervalued by insurers but commands significant non-economic damages.
Spinal Cord and Back Injuries Herniated discs, fractured vertebrae, and spinal cord injuries are common in motorcycle crashes — particularly in rear-end and T-bone collisions. I have secured $650,000 and $495,000 in lumbar spine injury cases.
Fractures Broken legs, arms, wrists, collarbones, and pelvises are among the most common motorcycle injuries. Complex fractures often require surgical repair with hardware, followed by months of physical therapy.
Internal Injuries Blunt force trauma from a collision can cause internal bleeding, organ damage, and pneumothorax — injuries that may not be immediately apparent and can be life-threatening without prompt treatment.
Psychological Injuries PTSD, anxiety, and fear of riding again following a serious motorcycle crash are real and compensable injuries. Many riders who loved motorcycling find they cannot return to riding after a serious accident — a loss that is part of your non-economic damages claim.
Where Riders Actually Get Hurt in San Francisco
San Francisco is a small city with a concentrated crash problem. The San Francisco Municipal Transportation Agency’s 2024 High Injury Network, built from collision data collected between 2020 and 2024, identifies 13 percent of city streets where 74 percent of the city’s serious traffic injuries and fatalities occur. If your crash happened on one of those corridors, that is not incidental — it is evidence about the roadway, the traffic controls, and what the city knew.
The corridors that generate the most motorcycle claims in my practice share the same features: multiple lanes, high posted speeds relative to the surrounding grid, frequent unprotected left turns, and heavy competition for space between cars, buses, delivery vehicles, and bikes.
- Market Street and the downtown grid. Restricted private-vehicle access has changed the traffic mix but not the conflict points. Drivers unfamiliar with the restrictions make sudden, illegal turns across a rider’s path.
- Van Ness Avenue and the South Van Ness corridor. Wide, fast, and full of buses pulling in and out of center-running lanes.
- 19th Avenue and Park Presidio. A state highway running through residential neighborhoods. Speed differentials here are the single most dangerous factor for a rider.
- The Embarcadero. Tourist traffic, rideshare pickups, streetcar tracks, and abrupt curb-side stops.
- Bayshore Boulevard and the Third Street corridor. Industrial traffic, heavy trucks, and long sight lines that encourage speed.
- Freeway on-ramps and off-ramps at I-80, US-101, and I-280. Merge-point collisions are the ones where lane splitting comes up first.
Streetcar and light-rail tracks deserve their own mention. Wet steel rails set into asphalt at an oblique angle will drop a motorcycle with no warning and no time to correct. Those cases are not always simple negligence claims against another driver — sometimes the defendant is a public entity, which changes the deadline entirely. More on that below.
Lane Splitting and the Blame Game
California is the only state that expressly authorizes lane splitting. Vehicle Code section 21658.1 defines it as riding between rows of stopped or moving vehicles in the same lane, and it directs the California Highway Patrol to develop educational guidelines. What the statute does not do is set a speed limit for lane splitting, and it does not make lane splitting negligent per se.
That distinction matters enormously, because the first thing almost every insurance adjuster does in a San Francisco motorcycle claim is assert that the rider was splitting lanes and therefore at fault. It is a reflex. It shows up in the recorded statement request, in the reservation-of-rights letter, and in the initial offer.
Lane splitting is lawful. Whether a particular instance of it was reasonable is a question of fact — speed differential, traffic conditions, lane width, visibility, and what the other driver did. California applies pure comparative negligence under Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, which means that even a rider found partly at fault still recovers, reduced by that percentage. An adjuster who tells you that lane splitting bars your claim is either wrong or hoping you do not know better.
Exactly What to Do After a Motorcycle Crash in California
- Get medical attention the same day, even if you feel fine. Adrenaline masks injuries for hours. A gap between the crash date and the first treatment date is the single most common argument insurers use to devalue a motorcycle claim.
- Make sure a police report gets written. In San Francisco that is usually SFPD; on the freeways it is CHP. Get the report number at the scene.
- Photograph the scene before anything moves — final rest positions, debris field, skid marks, the other driver’s damage, traffic controls, lane markings, and the roadway surface. If tracks, a pothole, or a utility trench contributed, photograph that too.
- Get names and phone numbers of witnesses. The police report frequently omits them, and they are almost impossible to find later.
- Do not give a recorded statement to the other driver’s insurer. You are not required to. Adjusters are trained to elicit admissions about speed and lane position.
- Preserve the motorcycle and the gear. Do not let the insurer take the bike for salvage before it has been inspected and photographed. Your helmet, jacket, and gloves are physical evidence of impact forces.
- Report the claim to your own insurer. Even where the other driver is at fault, your uninsured/underinsured motorist coverage may be the real source of recovery, and most policies require prompt notice.
- Watch the deadlines. Two years from the date of injury for most personal injury claims under Code of Civil Procedure section 335.1. Six months if a public entity is involved, under Government Code section 911.2.
What Compensation Can You Recover?
You may be entitled to compensation for emergency medical care, surgery, and hospitalization, future medical costs including rehabilitation and long-term care, lost wages and diminished earning capacity, pain and suffering, emotional distress and PTSD, permanent disability or disfigurement, and damage to your motorcycle and gear.
Common Questions About Motorcycle Accident Claims in San Francisco
Liability depends on the specific facts of your crash. In most cases the at-fault driver bears primary responsibility, but I investigate every potential avenue of recovery. An employer may be liable if a commercial driver was on the job. Rideshare companies like Uber or Lyft may be liable if their driver caused the crash. The City of San Francisco may be liable if dangerous road conditions, poorly maintained pavement, or defective traffic signals contributed. A vehicle or parts manufacturer may be liable if a defect caused or worsened the crash. Identifying every liable party is critical in motorcycle cases — damages are often severe and insurance limits may be insufficient without pursuing multiple defendants.
Call 911 — a police report is essential evidence even if injuries seem minor. Seek medical attention right away — adrenaline masks serious injuries including traumatic brain injuries, internal bleeding, and spinal trauma. If physically able, photograph and video the scene thoroughly — the vehicles, road conditions, skid marks, traffic signals, your gear, and your injuries — before anything is moved. Get the other driver’s insurance information, license plate, and contact details. Collect names and phone numbers of witnesses. Preserve your damaged motorcycle and riding gear — both are critical evidence and should not be repaired until your attorney has documented them. Do not give a recorded statement to any insurance company before speaking with me.
California is the only state that explicitly permits lane splitting under California Vehicle Code Section 21658.1, so riding between lanes is legal here. However insurance companies routinely argue that lane splitting contributed to your crash in order to reduce your payout under California’s comparative negligence rules. I know exactly how to counter these arguments — with traffic engineering evidence, CHP lane splitting guidelines, and accident reconstruction when necessary. Legal lane splitting does not bar your recovery and I fight hard to make sure insurers don’t use it against you.
Generally two years from the date of your accident under California’s statute of limitations. However if a government entity is responsible — such as the City of San Francisco for dangerous road conditions, Caltrans for freeway hazards, or a public agency vehicle — you may have as little as six months to file a government tort claim. Missing that deadline permanently bars your recovery. Contact me immediately so I can identify all liable parties and protect your rights before any deadline passes.
Yes — but helmet use matters in California. Under California Vehicle Code Section 27803, helmet use is required for all motorcycle riders. If you were not wearing a helmet and suffered head injuries, insurance companies will argue your injuries were worsened by your own negligence, potentially reducing your recovery under comparative fault rules. However not wearing a helmet does not bar your claim entirely. I work with medical experts to establish what injuries would have occurred regardless of helmet use and fight to maximize your recovery under the specific facts of your case.
Motorcycle accident victims typically suffer more severe injuries than car accident victims due to lack of protection — which means damages are often substantial. Compensation can include emergency and ongoing medical treatment, future medical costs, lost wages, diminished earning capacity, pain and suffering, emotional distress, motorcycle repair or replacement, and permanent disability. The value of your specific case depends on injury severity, liability clarity, and available insurance coverage. I have recovered multi-million dollar results for Bay Area accident victims and offer free consultations to evaluate your situation.
Nothing upfront. I handle all motorcycle accident cases on a pure contingency-fee basis — you pay no attorney fees unless I recover compensation for you. No hourly charges, no upfront costs. My fee is a percentage of your final settlement or verdict, clearly explained in writing before you sign anything. If I don’t win, you don’t pay.
That is common. California’s minimum liability limits rose to $30,000 per person and $60,000 per accident on January 1, 2025, but a serious motorcycle injury exceeds that immediately. Your own underinsured motorist coverage under Insurance Code section 11580.2 sits on top of the at-fault driver’s policy. Recovering on it usually means an arbitration against your own insurer, not a negotiation with the other side.
You may still have a claim, but it is a claim against a public entity, and the six-month Government Claims Act deadline under Government Code section 911.2 applies instead of the usual two years. You will also need to show the entity had actual or constructive notice of the dangerous condition under Government Code section 835. Photograph the condition immediately and call a lawyer the same week.
How Insurance Companies Fight Motorcycle Accident Claims — And How I Fight Back
Motorcyclists face unique bias in personal injury claims. Insurers exploit stereotypes about riders to minimize payouts. Here is what to expect:
“The Motorcyclist Was Speeding or Lane Splitting Recklessly” California permits lane splitting but insurers routinely argue it was unsafe in the specific circumstances. I obtain traffic camera footage, witness testimony, and accident reconstruction to establish your speed and the reasonableness of your lane splitting at the time of the crash.
“The Rider Assumed the Risk” Insurers argue that riding a motorcycle is inherently dangerous and that serious injury was foreseeable. California law does not bar recovery based on assumed risk when a third party’s negligence caused the crash. I establish the driver’s specific negligence and its direct causal role in your injuries.
“You Weren’t Wearing Proper Gear” Absence of a helmet (for adults), protective clothing, or other gear is used to argue comparative fault. I counter with medical evidence showing the nature of your injuries and whether gear would have made any difference in the specific collision dynamics.
“The Injuries Are Exaggerated” Road rash, PTSD, and chronic pain following motorcycle crashes are frequently minimized. I build objective evidence through medical records, treating physician testimony, psychological evaluations, and testimony from family members and colleagues who observed the impact on your life.

The Insurance Reality in California — What Changed in 2025
Senate Bill 1107 raised California’s minimum auto liability limits on January 1, 2025, for the first time in more than half a century. The minimums went from 15/30/5 to 30/60/15: $30,000 for bodily injury to one person, $60,000 total per accident, and $15,000 for property damage. Minimum uninsured and underinsured motorist coverage rose to match.
That sounds like good news, and it is — but read it carefully. A motorcycle crash that produces a fractured femur, an ORIF surgery, and three months out of work will exceed $30,000 in medical billing alone. The new minimum is still a floor that a serious rider injury blows through immediately.
This is why the underinsured motorist claim is often the real case. Under Insurance Code section 11580.2, your own UIM coverage sits on top of the at-fault driver’s policy once that policy is exhausted. Recovering on it means proving your damages to your own insurance company — which, at that point, is adversarial. I have arbitrated these. In one, I obtained a $750,000 award in an underinsured motorist arbitration involving mild traumatic brain injury from a rear-end collision, far above the insurer’s initial offer, by proving long-term cognitive and emotional impacts through expert evidence.
One more California-specific wrinkle: Civil Code section 1431.2, enacted by Proposition 51, makes defendants severally liable for non-economic damages in proportion to their share of fault. In a multi-vehicle motorcycle crash, apportionment is not an academic exercise — it determines what you actually collect.
Local Court and Claims Realities
Cases that do not settle are filed in San Francisco Superior Court, and the civil courthouse at 400 McAllister Street has its own rhythm. San Francisco jury pools are, in my experience, more receptive to motorcyclists than juries in some surrounding counties — they see riders every day and are less likely to start from the assumption that a motorcycle is a reckless choice. Defense counsel know that too, and it affects settlement posture.
If a public entity contributed to the crash — a dangerous roadway condition, a defective traffic signal, a Muni vehicle, a poorly executed trench repair, exposed rail — the case is governed by the Government Claims Act. Under Government Code section 911.2, you must present a written claim against a public entity within six months of the injury. Under Government Code section 835, you also have to prove the entity had actual or constructive notice of the dangerous condition long enough before the crash to have fixed it. Miss the six-month window and there is usually no case, no matter how strong the liability facts are. This is the deadline that quietly destroys more San Francisco road-defect claims than any other.
Case Results
- $6 million — settlement for a pedestrian struck by a vehicle who suffered a traumatic brain injury
- $2.185 million — settlement in a traumatic brain injury case (pedestrian vs. auto)
- $1.6 million — settlement for multiple severe fractures and long-term disability (pedestrian vs. auto)
- $750,000 — arbitration award in an underinsured motorist claim involving mild traumatic brain injury
Prior results do not guarantee or predict a similar outcome in any future case. Every case turns on its own facts.
Who I Fight For — and Who I Don’t
I take motorcycle cases where someone was seriously hurt and someone else was responsible. Broken bones that required surgery. Head injuries, including the ones that do not show on a CT scan — see my page on what a San Francisco brain injury lawyer does with those cases. Spinal cord injuries. Cases where the rider is being blamed for lane splitting and the facts say otherwise. Cases where the at-fault driver’s policy is too small and the underinsured motorist claim has to be arbitrated. Cases involving a public entity and a dangerous roadway, where the six-month clock is already running. And, when a rider does not survive, a wrongful death claim on behalf of the family.
I am not the right lawyer for every case. I do not handle motorcycle citations or DUI defense. I do not take property-damage-only claims — if your bike was wrecked but you were not injured, your own insurer can resolve that faster and cheaper than I can. And I turn down cases where I do not think I can add value over what you could negotiate yourself. You will get that answer on the first call, for free, rather than after three months of silence.
You also will not be handed off. I handle every case in this office myself, from the first call through settlement or trial. That is a deliberate limit on how many cases I take.
