Motorcycle Accident Lawyer in California

Motorcycles make up a small fraction of vehicles on California roads, but riders account for a disproportionate share of serious traffic injuries and deaths every year. If you've been hurt in a crash, you're probably dealing with a combination of medical bills, lost income, and an insurance adjuster who has already decided the biker was at fault before the report is even finished. None of that is unusual, and none of it means you're out of options.

Why Motorcycle Accident Claims Are Different

Insurance companies treat motorcycle claims differently than car accident claims, and not in the rider's favor. Adjusters often lean on stereotypes — that riders are reckless, that they were "probably speeding," that lane splitting itself caused the crash — to minimize or deny a claim before a real investigation happens. Motorcycle injuries also tend to be more severe than injuries from a comparable car crash, since riders have none of the steel, airbags, or crumple zones that protect drivers. That combination of aggressive claims-handling and higher-stakes injuries is exactly why riders benefit from a lawyer who handles these cases regularly, not just car accidents generally.

Common Causes of Motorcycle Accidents in California

Most motorcycle crashes trace back to a handful of recurring causes:

• Left-turn collisions, where a driver turns across an intersection without seeing an oncoming motorcycle
• Unsafe lane changes, where a driver merges into a rider's lane or blind spot
• Following too closely or failing to stop in time when traffic slows
• Distracted or impaired driving by the other motorist
• Road hazards like potholes, debris, or uneven pavement that a car would absorb but a motorcycle cannot
• Dooring, when a parked car's door opens into a rider's path

Identifying the actual cause matters because it determines who is liable — and it's rarely as simple as an insurer's first assessment suggests.

Is Lane Splitting Legal in California?

Yes. California is the only state that expressly authorizes lane splitting (riding between lanes of stopped or slow-moving traffic) under Vehicle Code Section 21658.1. The California Highway Patrol publishes safety guidance for doing it reasonably — generally recommending riders split at speeds no more than 10 mph faster than surrounding traffic and avoid splitting near freeway exits or in heavy congestion. Lane splitting alone does not make a rider automatically at fault for a crash. If you were splitting lanes safely and a driver hit you, insurers will often try to use the lane-splitting itself as a reason to deny the claim — that's a tactic, not an accurate statement of the law.

Fault, Comparative Negligence, and Your Recovery

California follows a pure comparative negligence rule. Even if you were partly at fault for a crash — say, 20% — you can still recover damages, just reduced by your share of fault (an 80% recovery in that example). This matters enormously for riders, because insurers frequently try to inflate a motorcyclist's percentage of fault to shrink or eliminate a payout. A lawyer can push back on that assessment with accident reconstruction, witness statements, and photos or video from the scene.

What to Do After a Motorcycle Accident

If you're able to, taking these steps protects both your health and your claim:

1. Get medical attention immediately, even if you feel okay — some injuries, especially head and internal injuries, aren't obvious right away.
2. Call the police and get a report filed; do not accept blame at the scene.
3. Document everything — photos of the bike, the road, your gear, and your injuries; contact information for witnesses.
4. Keep your damaged gear, including your helmet, which is often key evidence.
5. Avoid giving a recorded statement to the other driver's insurance company before speaking with a lawyer.
6. Track your losses, including medical bills, missed work, and property damage to the motorcycle itself.

What Compensation Can Cover

Depending on the facts of your case, a motorcycle accident claim may account for medical expenses (past and future), lost wages and diminished earning capacity, pain and suffering, property damage to the motorcycle and gear, and, in cases involving permanent injury, the long-term cost of care. Settlement amounts vary widely and depend on the severity of the injury, available insurance coverage, and how clearly fault can be established — there's no fixed formula, and any lawyer who promises a specific number before reviewing your case isn't giving you a realistic answer. For a broader look at how these numbers are typically built, see our overview of how car accident settlements work in California.

Insurance minimums also matter here. As of January 2025, California's minimum liability limits increased to $30,000 per person / $60,000 per accident for injury or death, and $15,000 for property damage — but many riders carry catastrophic injuries that far exceed even the at-fault driver's policy limits, which is when uninsured/underinsured motorist coverage becomes critical to a full recovery.

Catastrophic Injuries and Wrongful Death

Motorcycle crashes are disproportionately likely to cause traumatic brain injury, spinal cord damage, severe fractures, and road rash requiring skin grafts — injuries that can mean months of treatment and a permanent change in someone's ability to work or live independently. If you or a family member is facing this kind of injury, it's worth speaking with an attorney who handles catastrophic injury claims specifically, since these cases require a different level of medical and economic documentation than a routine claim.

California's Deadline to File

In most California personal injury cases, including motorcycle accidents, you generally have two years from the date of the crash to file a lawsuit under the statute of limitations. If a government vehicle or entity was involved, that window shrinks dramatically — you typically must file a formal claim within six months. Missing these deadlines can permanently bar your right to recover, so it's worth talking to a lawyer well before time runs short, even if you're still negotiating with an insurer.

Frequently Asked Questions

Can a passenger sue after a motorcycle accident in California?

Yes. A passenger injured in a motorcycle accident can generally pursue a claim against the at-fault driver — whether that's the motorcycle operator, another motorist, or both — regardless of who was riding the bike.

How is fault determined in a motorcycle accident in California?

Fault is determined through evidence: police reports, witness statements, physical evidence at the scene, traffic camera or dashcam footage, and sometimes accident reconstruction. Because California uses comparative negligence, more than one party can share fault.

What should I do immediately after a motorcycle accident?

Prioritize medical care, call the police to file a report, document the scene and your injuries, and avoid making recorded statements to insurance adjusters until you've spoken with an attorney.

Do I need a lawyer if the insurance company already offered me a settlement?

It's worth having a lawyer review any offer before you accept it. Initial offers are often calculated to close the claim quickly and cheaply, and accepting one typically ends your ability to seek more money later, even if your injuries turn out to be worse than expected.

How long do I have to file a motorcycle accident claim in California?

Generally two years from the date of the accident, or six months if a government entity is involved. Deadlines can vary based on the specifics of your case, so confirm your timeline with an attorney as soon as possible.
