Injured by a Self-Driving Car in California: Who's Responsible When No One Was Behind the Wheel?

KEY TAKEAWAYS:

When a driverless vehicle causes a crash in California, responsibility may fall on the company operating the vehicle, the manufacturer, another motorist, or multiple parties. Depending on what went wrong, a claim may involve negligence, product liability, or both.

Autonomous vehicle crashes can also leave a unique evidence trail, including DMV collision reports, sensor data, camera footage, and records of braking, steering, and system performance. Quickly preserving this evidence can help determine why the vehicle crashed and who may be responsible.

You are stopped at a light on Camino del Rio North when a white SUV rolls through and clips your front quarter panel. You walk up to exchange information, and there is nobody in the driver's seat. Instead, you may need to contact the company operating the vehicle through its remote support system or follow instructions displayed on or inside the vehicle.

Driverless vehicles now operate commercial passenger service in several California cities, and testing permits extend well beyond those cities. If one hits you, your claim does not disappear because the seat was empty. However, your claim for compensation is more complicated than most car crash cases. At the Law Offices of Mark C. Blane, APC, our experienced San Diego car accident lawyer can identify all liable parties and fight with their insurance companies for the compensation you deserve for your injuries. 

Who Do You File a Claim Against After a Driverless Car Crash?

When a self-driving car causes a crash in California, there may not be a human driver to hold responsible. Instead, determining liability requires looking at what went wrong and who was responsible for the vehicle, technology, or conduct that caused the collision. Depending on the circumstances, potentially responsible parties may include:

• The autonomous vehicle manufacturer or technology developer. A defect or failure involving the automated driving system could raise questions about the company responsible for its design or operation.
• The fleet operator or ridesharing company. A company operating autonomous vehicles for commercial passenger service may bear responsibility depending on its role in the crash.
• A component supplier. A failed lidar sensor, camera, braking component, or other technology could contribute to a collision.
• A maintenance contractor. Improperly serviced sensors, brakes, or other vehicle systems could have caused an accident.
• A remote driver. California regulations recognize remote drivers who can perform driving tasks such as steering, braking, and acceleration from outside the vehicle.
• Another driver or responsible public entity. A negligent motorist or dangerous road condition may contribute to a crash even when an autonomous vehicle is involved.

How California Law Defines the Driver When There Isn't One

California Vehicle Code § 38750(a)(4) defines the “operator” of an autonomous vehicle as the person seated in the driver’s seat or, if no one is in that seat, the person who causes the autonomous technology to engage. That definition helps identify the vehicle’s operator, but it does not automatically determine who is legally responsible when a driverless vehicle causes a crash.

Liability still depends on what caused the collision and the roles of the people or companies involved. Depending on the circumstances, responsibility could involve the autonomous vehicle manufacturer or operator, a technology or component provider, a remote driver, another motorist, or another party whose actions contributed to the crash.

California also imposes financial responsibility, reporting, and safety requirements on companies that test and deploy autonomous vehicles. Expanded California State Department of Motor Vehicles (DMV) regulations that took effect in 2026 strengthened oversight and allowed law enforcement to report traffic violations committed by driverless vehicles to the DMV, which can investigate and take action against the manufacturer.

Why These Claims Don't Work Like a Normal Car Accident Case

A standard crash claim often focuses on whether a driver was negligent. A self-driving car accident may raise additional questions about whether the automated driving system or another vehicle component was defective. Depending on what caused the crash, the case could involve negligence, product liability, or both.

Several practical differences may affect an autonomous vehicle claim:

• Product liability may change what must be proven. Some California strict product liability claims do not require proof that the manufacturer acted negligently. The evidence and legal standard depend on the type of alleged defect.
• Corporate defendants may be involved. A manufacturer, technology developer, fleet operator, or other business could be among the parties investigated following a crash involving a driverless vehicle.
• Electronic evidence can become critical. Software records, sensor data, camera footage, and vehicle logs may help reveal what the automated driving system detected and how the vehicle responded before impact.
• Technical issues may require additional analysis. Depending on the case, engineers or other qualified expert witnesses may be needed to interpret vehicle technology and explain how a failure contributed to the crash, adding another layer to the steps in a car accident lawsuit.
• More than one source of insurance may need review. Coverage could depend on the parties involved and the applicable policies, including commercial or fleet coverage and, in some circumstances, the injured person's own auto insurance.

What Evidence Do You Need in a Self-Driving Car Accident Case?

Self-driving vehicles can generate electronic evidence that does not exist in a conventional crash. Sensor data, camera footage, and vehicle records may help show what the automated driving system detected and how it responded before impact. Under California’s 2026 autonomous vehicle regulations, applicable sensor data captured around a collision must be preserved for at least three years. Preserving and requesting this information early can be an important part of the collision investigation.

• Sensor data. Records may show what the vehicle's sensors detected before impact, adding additional evidence to support a car accident claim in a conventional case.
• Onboard camera footage. Video may help establish the position and movement of vehicles, pedestrians, and other objects before the crash, much as dashcam footage supports a car accident claim involving human drivers.
• Vehicle and software records. Depending on the information available, records of the automated driving system and its operation may help investigators determine how the vehicle responded before impact.
• System disengagement or intervention data. In cases where this information exists, it may show whether autonomous mode disengaged or a human or remote driver intervened before the collision.
• California DMV collision records. Manufacturers testing autonomous vehicles must report qualifying collisions involving property damage, bodily injury, or death. The DMV's autonomous vehicle collision reports can provide another potential source of information about a crash.

Why Work With The Law Offices of Mark C. Blane, APC

A self-driving car accident can demand a different kind of investigation. Instead of focusing only on what a human driver did wrong, the case may require examining sensor data, vehicle records, camera footage, software information, and the roles of multiple companies. Identifying and preserving that evidence early can help uncover what happened before crucial details become harder to obtain.

Attorney Mark C. Blane has represented injured people in San Diego since 1999 and personally meets with every client rather than handing that responsibility to a paralegal. That individual attention matters when a case requires piecing together both the technical cause of a collision and its human cost—from medical treatment and lost income to the ways an injury disrupts everyday life.

The Law Offices of Mark C. Blane, APC, brings the same careful approach used to protect clients’ rights after a car accident to emerging claims involving autonomous vehicles. When technology changes, the goal does not: identify who may be responsible, preserve the evidence, document the full impact of the injuries, and build a strong claim to help you obtain the compensation you deserve.
