Motorcycle crash victims in California face a challenge that car accident victims rarely encounter before an insurance adjuster reviews the facts, riders are often presumed reckless. This bias can affect how claims are valued and disputed, especially when lane splitting which is legal in California is involved. Here is what the law says, why these claims can be unfairly difficult, and how to protect your case.
Lane Splitting Is Legal in California But Expect to Be Blamed for It Anyway
California is the only state that has explicitly addressed lane splitting in its vehicle code. Under Vehicle Code section 21658.1, lane splitting is defined as a motorcyclist driving “between rows of stopped or moving vehicles in the same lane,” and the statute directs the California Highway Patrol to develop educational safety guidelines for both motorcyclists and the drivers around them. Lane splitting itself is not against the law in California but that doesn’t stop insurance adjusters from using it as a go-to argument to shift blame onto an injured rider, even when the other driver changed lanes without checking or opened a car door into traffic.

The Risk Riders Actually Face
The numbers explain why motorcycle injuries tend to be so severe. According to NHTSA, motorcyclists are almost 27 times more likely than passenger vehicle occupants to die in a crash per vehicle mile traveled, and nearly 5 times more likely to be injured. In 2024, 6,228 motorcyclists were killed nationwide among the highest totals recorded since NHTSA began tracking this data. With a motorcycle offering none of the structural protection of a car, even a relatively minor collision can cause life-altering injuries.
That exposure is exactly why fair compensation matters so much in these cases and why insurers fight so hard to avoid paying full value.
The “Biker Bias” Problem in Insurance Claims
Insurance adjusters and, at times, juries carry assumptions about motorcyclists being inherently reckless, which can unfairly affect how a claim is evaluated regardless of the facts. In practice, this bias shows up in a few predictable ways:
- Assuming speed or lane splitting caused the crash before any investigation has taken place.
- Downplaying injuries or arguing that a rider should have been wearing more protective gear, even where California has no law requiring specific gear beyond a DOT-compliant helmet.
- Pointing to the rider’s choice to ride a motorcycle at all as some form of assumed risk, which is not how California comparative negligence law works.
California’s pure comparative negligence rule applies to motorcycle crashes exactly as it would to any other vehicle collision: an injured rider can still recover damages even if found partially at fault, with the award reduced not eliminated by their share of responsibility. Overcoming built-in bias often requires strong independent evidence: scene photos, witness statements, event data from the vehicles involved, and sometimes accident reconstruction.

Who Can Be Held Liable
- The other driver: most motorcycle crashes involving another vehicle happen because a driver failed to see the motorcyclist, often while turning left or changing lanes.
- A vehicle or parts manufacturer: if a defective tire, brake system, or motorcycle component contributed to the crash.
- A government entity: for hazardous road conditions such as unmarked potholes, debris, or poor signage, subject to the Government Claims Act’s six-month notice deadline.
- An uninsured or underinsured driver: which is why uninsured/underinsured motorist coverage on a rider’s own policy is often critical to a full recovery.

What to Do After a Motorcycle Accident in California
- Get medical attention right away adrenaline can mask serious injuries immediately after a crash.
- Photograph everything the vehicles, the road, skid marks, your gear, and your injuries before the scene changes.
- Get the other driver’s insurance and contact information and identify any witnesses.
- Don’t accept an early blame narrative from the other driver’s insurer, especially one centered on lane splitting or “motorcycles are dangerous” assumptions.
- Preserve your motorcycle and gear exactly as they were after the crash they may be important evidence, including for a potential product liability claim.
- Act within the statute of limitations. California generally gives you two years from the date of the crash to file suit under Code of Civil Procedure § 335.1.
Frequently Asked Questions
Is lane splitting illegal in California?
No. California Vehicle Code § 21658.1 explicitly contemplates lane splitting and directs the CHP to issue safety guidelines for it. It is not, by itself, against the law.
Can I still recover damages if I was lane splitting when the crash happened?
Potentially yes. Lane splitting isn’t illegal, so the real question is whether it was done safely under the circumstances and whether the other driver’s negligence caused or contributed to the crash. California’s comparative negligence rule still allows recovery even if fault is shared.
Do I need special gear for a claim to be valid?
California law requires a DOT-compliant helmet, but there’s no legal requirement for additional gear. An insurer may still try to argue that a lack of extra protective gear increased your injuries, which is a factual dispute your attorney can push back on.
What if the other driver has no insurance?
Uninsured/underinsured motorist coverage on your own policy may apply. This is one of the most important coverages a motorcyclist can carry, given how often at-fault drivers in motorcycle crashes are uninsured or underinsured.
