What if the driver who hit me in Diamond Bar had no insurance?

If a driver hits you in Diamond Bar and does not have insurance, collecting the money you need for your injuries can become more complicated, but it is not impossible. Your own uninsured motorist (UM) or underinsured motorist (UIM) coverage can provide compensation, if you have it.

California law requires drivers to have minimum liability insurance coverage, currently at $30,000 for injury or death to one person and $60,000 for injury or death to more than one person per incident for policies issued or renewed from January 1, 2025. Uninsured motorist coverage is optional but can protect you when the at-fault driver is uninsured or their insurance is not enough to cover your damages. Understanding your policy and the types of coverage available can make a difference in your recovery after a collision.

Where do I file a motorcycle accident claim in Diamond Bar?

A personal injury case resulting from a motorcycle accident in Diamond Bar is filed in the Superior Court of California, County of Los Angeles. These claims are assigned to the East District's Personal Injury Hub department, located at the Pomona Courthouse South.

The Pomona Courthouse South is at 400 Civic Center Plaza, Pomona, CA 91766. Los Angeles County Local Rule 2.3 and the General Order regarding Assignment and Transfer of Personal Injury Cases (effective May 17, 2024) dictate that personal injury cases are filed in the judicial district where the incident occurred. Your attorney confirms the correct filing location.

What steps should I take after a motorcycle accident?

  1. Ensure Safety and Seek Medical Attention: Move yourself and your motorcycle to a safe location if possible. Call 911 immediately to report the accident and request emergency medical services, even if your injuries seem minor. Some serious injuries, like catastrophic injuries, may not show symptoms right away.
  2. Report the Accident to Law Enforcement: Wait for law enforcement officers to arrive. They will create an official accident report documenting the scene, which can be important evidence for your claim.
  3. Exchange Information: Get the name, contact information, insurance details, and driver's license number from all involved parties. Note the make, model, and license plate of other vehicles.
  4. Document the Scene: Use your phone to take photos and videos of the accident scene, vehicle damage, road conditions, traffic signs, and any visible injuries. Gather contact information from any witnesses.
  5. Notify Your Insurance Company: Report the accident to your own insurance provider as soon as you can. Provide factual information, but avoid discussing fault or making recorded statements before speaking with a lawyer.
  6. Consult with a Motorcycle Accident Attorney: Before speaking further with insurance companies or accepting any settlement offers, talk to a lawyer. A lawyer can explain your rights and help you pursue full compensation available under California law.

How long do I have to file a motorcycle accident lawsuit, and what can I recover?

Most personal injury lawsuits, including those for motorcycle accidents, must be filed within two years from the date of the injury under California Code of Civil Procedure § 335.1. If your claim is against a city, county, or other public entity, a written claim must be presented within six months of the accident, as per California Government Code § 911.2.

The deadline is generally paused while an injured person is a minor under California Code of Civil Procedure § 352, but § 352(b) removes that pause for claims against public entities under the Government Claims Act. What a claim is worth depends on the specific facts; California law allows recovery for medical costs, lost earnings, and non-economic harm such as pain and suffering. If a motorcycle accident results in a death, a wrongful death claim can seek compensation for the financial support and companionship the deceased provided. However, for survival actions filed on or after January 1, 2026, California Code of Civil Procedure § 377.34 does not allow recovery for the decedent's pre-death pain, suffering, or disfigurement.

Frequently Asked Questions

What should I do if the other driver's insurance company contacts me after a Diamond Bar motorcycle accident?

If the other driver's insurance company contacts you, you should decline to provide a recorded statement or discuss fault. Direct them to your attorney. Insurance adjusters are trained to minimize payouts, and anything you say can be used against your claim. It is best to have a legal representative handle all communications with insurance companies on your behalf.

Can I still file a claim if I was partly at fault for a motorcycle accident in Diamond Bar?

Yes, California follows a "pure comparative negligence" rule. This means you can still recover damages even if you were partly at fault for the accident. Your compensation would be reduced by your percentage of fault. For example, if you were found 20% at fault, you would recover 80% of your total damages. A lawyer can help determine the actual fault and protect your right to compensation.

How much does it cost to hire a motorcycle accident attorney in Diamond Bar?

Casa Legal Los Angeles works on a contingency fee basis for motorcycle accident cases. This means you pay no attorney's fees unless we win your case – and no case costs either. Our payment comes as a percentage of the compensation we secure for you, ensuring that quality legal representation is accessible without upfront costs.

Are motorcycle lane splitting laws relevant to my Diamond Bar accident claim?

California law defines lane splitting and authorizes the California Highway Patrol (CHP) to publish safety guidelines (Vehicle Code § 21658.1). It does not set a speed rule or create a safe harbor. If you were lane splitting when your accident occurred, the specific circumstances can influence your claim. The other driver might try to argue you were at fault, but an attorney can analyze the facts and California Vehicle Code to defend your rights.

Deadlines that apply in Diamond Bar

The California filing deadlines that apply to an incident in Diamond Bar (Los Angeles County) come from state statute, not a local rule. These are the deadlines cited most often.

2 years — personal injury lawsuit
Cal. Code Civ. Proc. § 335.1 — two years from the date of injury for most personal injury and wrongful death claims.
6 months — claim against a public entity
Cal. Gov. Code § 911.2 — a written claim must be presented to the public entity within six months for claims involving death or injury to person or personal property, before a lawsuit may be filed.
Injured minors
Cal. Code Civ. Proc. § 352 — the limitations period is generally tolled while the injured person is a minor, but the six-month government claim deadline is not tolled the same way.

This is general information about California law, not legal advice, and reading it does not create an attorney-client relationship. Deadlines change with the facts and with who the defendant is — a claim against a city, county, transit agency, or the state triggers a much shorter deadline, and delayed discovery, tolling, and other exceptions apply. Casa Legal Los Angeles is licensed to practice in California. Confirm any deadline with an attorney.
