Short answer: When an autonomous vehicle strikes a pedestrian, responsibility can fall on several parties at once, including the company that operates the vehicle, the manufacturer, the software developer, a component supplier, or a human safety operator if one was present. Because a self-driving system replaces the human driver, liability often shifts from a single motorist toward the businesses that built and deployed the technology. Determining who pays requires investigating the vehicle data, the system performance, and the conduct of everyone involved.
Autonomous vehicles are now a routine presence on California roads, and that makes a once hypothetical question urgent: when a driverless car injures a pedestrian or cyclist, who is responsible? The answer is rarely simple. These claims sit at the intersection of traditional negligence law, product liability, and a regulatory framework that is still taking shape. This article explains how liability is analyzed today and what an injured person should understand before pursuing a claim.
The Current State of Driverless Vehicle Technology
Self-driving technology has advanced well past its experimental phase. Companies including Waymo and Tesla now operate driverless fleets in San Francisco and other major metropolitan areas, often with no human operator in the driver seat. Independent safety research has also matured. A 2025 analysis of Waymo data covering 56.7 million rider-only miles, reviewed by the Insurance Institute for Highway Safety, found the vehicles were involved in about 1.28 police-reportable crashes per million miles, compared with 4.06 for human drivers. The same research reported 92 percent fewer pedestrian-injury crashes and 85 percent fewer cyclist-injury crashes than the human benchmark.
Those figures do not mean the technology is flawless. Fatal incidents involving automated systems have occurred, and as deployment expands across more cities, the total number of collisions involving autonomous vehicles will grow. Lower average crash rates also do little to help the individual pedestrian who is struck. For that person, the legal question is the same as in any serious injury case: who is accountable, and how is compensation recovered?
Understanding Liability in Autonomous Vehicle Accidents
In a conventional collision, liability usually rests with a driver who failed to exercise reasonable care. A driverless system removes that driver from the equation, so responsibility can move to the parties behind the technology.
Potential defendants include the vehicle owner or operator, any human safety operator present, the manufacturer, the software developer, and suppliers of sensors or other components. When the failure appears to stem from a design or manufacturing defect, the claim can proceed under product liability principles, which do not require proof that anyone acted carelessly, only that the product was unreasonably dangerous. When the failure appears to stem from how the vehicle was operated or maintained, ordinary negligence rules apply. Many autonomous vehicle claims involve both theories at the same time.
Determining which theory controls requires a thorough investigation. Relevant factors include the performance of the autonomous system, the vehicle sensor and event data, any defect in hardware or software, the behavior of the pedestrian, and the road and weather conditions at the time. This is very different from a routine car accident claim, where fault is often clear from the outset.
Levels of Automation and Why They Matter
Not every vehicle marketed as self-driving operates the same way, and the level of automation affects who is responsible. Lower levels, such as driver assistance and partial automation, still require a human to supervise and take control, so a human operator may share fault. Higher levels perform the entire driving task within a defined area without human input, which pushes responsibility toward the operator and manufacturer. Identifying the automation level engaged at the moment of a crash is a central question in these cases.
California Regulatory Framework
California maintains one of the more developed autonomous vehicle programs in the country, and it changed significantly in 2026. On April 28, 2026, the Department of Motor Vehicles finalized new regulations that strengthen state oversight and, for the first time, extend the framework to heavy-duty autonomous vehicles weighing more than 10,000 pounds, which had previously been excluded. The rules require manufacturers to complete staged testing, including 50,000 miles for light-duty vehicles and 500,000 miles for heavy-duty vehicles at each phase, before commercial deployment.
The updated framework also expands enforcement. Beginning July 1, 2026, law enforcement officers may issue a notice of autonomous vehicle noncompliance after observing a suspected traffic violation, and manufacturers must respond within 72 hours. Manufacturers must also report system failures, immobilizations, and collisions. For an injured pedestrian, these reporting duties matter, because the records they generate can become important evidence in a claim.
Insurance and How Victims Recover
Insurance for autonomous vehicles is still evolving. Coverage may run through the operator commercial policy, the manufacturer, or a combination, and identifying the right source of recovery is often more complex than in a standard collision. A pedestrian injured by a driverless vehicle should preserve every available record, seek medical care promptly, and avoid giving recorded statements to any insurer before understanding their rights. Because responsibility can be spread across several companies, having counsel coordinate the claim helps ensure that no responsible party is overlooked.
Pedestrians and Cyclists Face the Greatest Risk
Pedestrians and cyclists have no protection in a collision with a motor vehicle, autonomous or not, and they tend to suffer the most severe injuries. When a car hits a pedestrian, the consequences can include traumatic brain injury, spinal injury, and permanent disability. These are exactly the catastrophic-injury cases the trial team at Callahan & Blaine, PC is built to handle.

Frequently Asked Questions About Autonomous Vehicle Liability
Who Is Liable When a Fully Autonomous Vehicle Causes an Accident?
Responsibility can rest with the company that operates the vehicle, the manufacturer, the software developer, a component supplier, or more than one of them together. Because no human is driving, liability tends to shift toward the businesses that built and deployed the system, and a full investigation of the vehicle data is usually needed to identify who is accountable.
How Do Autonomous Vehicle Accidents Compare to Human Driver Accidents?
Independent 2025 research reviewed by the Insurance Institute for Highway Safety found that autonomous vehicles operated by Waymo were involved in fewer police-reportable crashes per mile than human drivers, including markedly fewer pedestrian-injury and cyclist-injury crashes. Averages across a fleet, however, do not determine fault in any single crash, which still turns on the specific facts.
What Should I Do if I Am Injured by an Autonomous Vehicle?
Seek medical care right away, report the crash, and preserve any evidence, including photographs and the names of witnesses. Avoid giving a recorded statement to an insurer before you understand your rights, and speak with a personal injury attorney who can request the vehicle data before it is lost.
How Does Insurance Work for Autonomous Vehicle Accidents?
Coverage may come from the operator commercial policy, the manufacturer, or a combination of sources. Identifying the correct source of recovery is often more complex than in a standard collision, which is one reason these claims benefit from experienced legal help.
Can Autonomous Vehicle Manufacturers Be Held Liable for Accidents?
Yes. When a crash results from a defect in the vehicle design, manufacturing, or software, the manufacturer or developer can be held responsible under product liability law, which does not require proof of carelessness, only that the product was unreasonably dangerous.
