Autonomous vehicles such as Waymo and Tesla have made travel more convenient. But when a self-driving car crashes, determining responsibility can be more complicated than in a traditional vehicle accident. A collision involving an autonomous driving vehicle may raise questions about the human operator, the vehicle manufacturer, the software, the sensors, or the automated driving technology.
Our San Diego self-driving car accident lawyers investigate these factors to determine how the crash happened and who may be legally responsible. Whether your accident occurred on Interstate 5, Interstate 805, State Route 163, or local streets, we can help you understand your legal options and pursue compensation for medical expenses, lost income, pain and suffering, and other losses.

Self-driving car accidents can be more complicated than traditional car accidents because the cause may not be limited to a driver’s actions. In a typical crash, investigators often examine factors such as speeding, distracted driving, or failing to yield, while an autonomous vehicle accident may involve software errors, faulty sensors, mapping problems, or failures in the vehicle’s automated driving system. Investigators need to review vehicle data, system logs, camera footage, software updates, and other technical evidence to understand what went wrong. Liability can also be more complicated because responsibility may potentially involve the driver, vehicle manufacturer, software developer, or another party.
As self-driving technology continues to expand in San Diego, these questions are becoming increasingly relevant. For example, Waymo has expanded its autonomous ride-hailing operations in the San Diego area, putting more self-driving vehicles on local roads and making it important for drivers, passengers, and pedestrians to understand how these crashes can differ from regular car accidents.
California law establishes specific requirements for autonomous vehicles operating on public roads. Under California Vehicle Code § 38750, an autonomous vehicle generally refers to a vehicle equipped with technology that can drive without the active physical control or monitoring of a human operator, including qualifying Level 3, Level 4, and Level 5 automated driving systems.
For autonomous vehicles operating without a human operator physically present, California law now requires additional safety and emergency-response measures. Beginning July 1, 2026, applicable manufacturers must maintain a dedicated emergency response telephone line and equip their vehicles with a two-way voice communication system that allows nearby emergency officials to communicate with a remote human operator.
The law also addresses evidence that may become important after an autonomous vehicle accident. Manufacturers must have a mechanism to capture and store autonomous technology sensor data from at least 30 seconds before a collision when the vehicle is operating in autonomous mode, and preserve the data for three years after the crash. This information may help investigators understand what the vehicle detected and how its automated driving system responded before the collision.
These requirements can make vehicle data, automation status, and communications with remote operators important evidence when investigating a self-driving car accident in San Diego.
Self-driving car accidents can involve complex questions about vehicle defects, autonomous driving software, sensor systems, driver conduct, and third-party negligence. Our experience with complex personal injury and product liability claims allows us to investigate these factors and pursue compensation from every responsible party.
A self-driving car accident can happen for many of the same reasons as a regular crash, but automated technology can introduce additional factors. Finding the cause often requires looking at both the human and technological sides of the accident.
Autonomous vehicle systems are designed to detect surrounding vehicles, pedestrians, cyclists, roadway markings, and other objects and then make driving decisions based on that information. When the system does not respond appropriately to a developing hazard, it can result in a serious autonomous collision.
Cameras, radar, lidar, GPS, mapping systems, the vehicle's sensors, and software all contribute to how an autonomous vehicle understands its surroundings. A sensor that fails to identify an object or software that misinterprets information can affect how the vehicle responds. Self-driving cars may also be vulnerable to cyber-attacks and hacking when connected systems or software are compromised. Tesla's Autopilot system, for example, has been involved in multiple fatal accidents, underscoring why software and sensor failures matter.
Calling a vehicle “self-driving” does not mean a human is always free from responsibility. Even in driverless cars, the level of automation matters. Depending on that level, the person in the driver's seat may still need to monitor the road, stay attentive, and take control when the system instructs them to. If the person was distracted, impaired, speeding, or failed to take control when required, their actions can contribute to the accident.
Self-driving technology still relies on a properly functioning vehicle. Brake failures, worn tires, damaged sensors, improperly repaired components, or other maintenance issues can affect the vehicle's ability to operate safely.
Poorly maintained pavement, unclear lane markings, construction zones, malfunctioning traffic signals, inadequate signage, or other roadway conditions can create difficult situations for both human drivers and automated vehicles.
A motorist who speeds, runs a red light, drives while distracted, follows too closely, or makes an unsafe lane change can collide with an autonomous vehicle just as they could with any other vehicle. In some crashes, third-party motorists or other road users may bear responsibility for the collision.
A self-driving car crash can cause serious injuries, even when the vehicle is designed to reduce human error. The sudden impact can place significant force on the body, leading to harm ranging from minor cuts and bruises to bodily injuries such as broken bones, head trauma, and spinal cord injuries. The extent of your injuries can also affect the compensation you may be able to pursue.
Some injuries commonly associated with serious self-driving car accidents include:
The first hour after a self-driving car accident can affect the evidence and documentation your claim may depend on later. If you got into a self-driving accident in San Diego, take the following steps to prioritize your safety, preserve information, and avoid actions that could interfere with the evidence.
Determining liability after a self-driving car accident in San Diego can be more complex than a typical motor vehicle collision. Several parties may share responsibility depending on what caused the crash, how the automated driving system operated, and whether another person or entity contributed to the accident. Identifying all potentially liable parties matters because it helps determine the full extent of compensation available to an injured victim and who bears financial responsibility for those losses.
Proving a self-driving car accident claim requires more than crash-scene photographs or statements from the people involved. Because autonomous vehicles rely on cameras, sensors, software, and other technology, evidence showing how the vehicle was operating before and during the collision can be especially important. Depending on the circumstances, useful evidence may include:
When you file a personal injury lawsuit after a self-driving vehicle accident, you may be able to recover economic and non-economic damages. These damages are intended to compensate you for the financial losses, physical injuries, and emotional effects caused by the accident. Depending on your case, damages may include medical treatment, physical therapy, lost income, lost future earnings, vehicle damage, future medical expenses, pain and suffering, emotional distress, loss of enjoyment of life, and loss of consortium.
Economic damages compensate you for losses you can generally calculate in monetary terms in injury claims. Depending on your injuries and the circumstances of the crash, these may include:
Non-economic damages compensate you for the physical and personal effects of your injuries that are more difficult to assign a specific dollar value. These may include:
In some self-driving car accident cases, punitive damages, also known as exemplary damages, may be available. These damages are different from compensatory damages because they are intended to punish particularly wrongful conduct and deter similar behavior in the future.
Ordinary negligence generally is not enough to support a punitive damages award. Under California law, punitive damages may be available when the defendant is found to have acted with malice, oppression, or fraud, subject to the applicable legal requirements.

Yes, you can prove fault in a self-driving car accident, but determining who is responsible can be more complicated than in a traditional car accident. Liability may involve the vehicle manufacturer, software developer, autonomous technology company, vehicle owner, or human operator. These cases often require reviewing technical evidence from autonomous vehicle technology beyond ordinary crash evidence. Evidence such as vehicle system logs, sensor data, camera footage, maintenance records, and witness statements can help determine what caused the crash and who may be legally responsible.
Yes, self-driving car accidents can differ from traditional vehicle crashes because they involve different safety risks, causes, and liability issues. Instead of being caused solely by driver behavior, an accident may involve problems with the vehicle’s sensors, software, automated driving system, or communication between different vehicle components. This makes it more challenging to determine exactly what went wrong and who should be held responsible.
Self-driving cars may improve road safety by reducing accidents caused by human error, but they are not completely risk-free. Autonomous vehicles rely on artificial intelligence, sensors, cameras, and complex software to make driving decisions, and these systems can still experience technical limitations or failures. Before manufacturers deploy autonomous vehicles, they must comply with applicable federal safety requirements and regulations enforced by the California Department of Motor Vehicles. Even with these safeguards, self-driving technology can still contribute to accidents under certain circumstances.
If several parties contributed to your self-driving car accident in San Diego, each may be found responsible for a portion of the crash. California follows a pure comparative negligence rule, which means your compensation can be reduced by your share of fault. For example, if a technology company is found 50% responsible, another driver 30% responsible, and you 20% responsible, your total compensation would generally be reduced by your 20% share.
