Who Is Liable When A Self-Driving Car Causes A Crash?

Liability for a self-driving car crash usually depends on two things: how much the car was driving itself at the moment of impact and what actually caused the collision. A human driver who was supposed to supervise a driver-assistance system may be responsible, while a vehicle manufacturer, software developer, or robotaxi operator may be liable when the automated system fails. In many crashes, fault is shared among several of these parties.

Byrd Davis Alden & Henrichson, LLP has helped injured Texans since 1959, and automated vehicles are now part of everyday traffic in Austin. If you were hurt in one of these crashes, an Austin car accident lawyer at our firm can investigate both the human and technical causes of the collision and identify every party who may owe you compensation.

Who May Be Liable in a Self-Driving Car Accident

Self-driving technology adds new potential defendants to a car accident claim. An investigation may examine the companies that built, programmed, owned, or operated the vehicle. The parties most often involved include the following.

• The human driver: A person who was required to monitor the vehicle and failed to take control when needed may be liable.
• The vehicle manufacturer: A design flaw, manufacturing defect, or inadequate warning about the system’s limits can shift responsibility to the automaker.
• The software developer: Errors in the code or decision-making algorithms that guide the vehicle may create liability for the company that wrote them.
• The fleet operator or owner: Companies running robotaxi services, and owners who skip required maintenance or updates, may share fault.
• Other drivers and third parties: Another negligent motorist, a repair shop, or the entity responsible for a dangerous roadway may also contribute.

Determining which of these parties is responsible usually requires reviewing both the crash scene and the data the vehicle recorded. The level of automation in use at the time of the collision is often the starting point.

Why the SAE Automation Level Matters for Liability

The Society of Automotive Engineers (SAE) classifies vehicle automation on a scale from Level 0, meaning no automation, to Level 5, meaning the vehicle can drive itself in all conditions. The level a vehicle was operating at during a crash has a direct effect on who may be held liable.

Levels 0 Through 2 Keep the Driver Responsible

At these levels, the human driver remains in control and must monitor the road at all times. Features such as adaptive cruise control and lane-keeping assist fall into this range, and Tesla’s Autopilot and Full Self-Driving systems are considered Level 2. If a crash occurs while one of these systems is active, the driver usually bears primary responsibility, just as in a conventional accident.

Level 3 Can Create Shared Liability

Level 3 automation allows the vehicle to handle driving in certain conditions but requires the driver to retake control when the system asks. If the system failed to give an adequate warning before handing control back, the manufacturer may bear responsibility. If the driver ignored a proper warning, liability may remain with the driver.

Levels 4 and 5 Shift Liability Toward Companies

At Level 4 and Level 5, the vehicle is designed to operate without human intervention. Waymo’s driverless ride-hailing vehicles are an example of Level 4 automation. When one of these vehicles causes a crash, responsibility tends to move toward the manufacturer, the software developer, or the company operating the vehicle, and a passenger with no ability to control the car is unlikely to be at fault.

When the Human Driver May Still Be Liable

Automation does not remove a driver’s legal duties. Most vehicles sold today with advanced driver-assistance features still require a person to watch the road and respond immediately when the system issues a warning. A driver who texts, falls asleep, or ignores repeated alerts while the system is engaged may be found negligent if a crash follows.

Drivers can also be responsible for misusing the technology, such as activating a highway-only feature on city streets or in weather it was not designed to handle. If an owner takes the vehicle off autopilot and drives it manually, the driver may be held liable for a crash just as in any other collision. Additionally, if a vehicle required servicing, sensor cleaning, or software updates to perform properly and the owner failed to provide them, the owner could be held liable if that failure contributed to an accident.

When the Manufacturer or Software Developer May Be Liable

As the Insurance Information Institute points out, reporting on a study by the RAND Corporation, many believe the focus is likely to shift from personal liability to manufacturer liability as more autonomous vehicles reach the road. When a crash is caused by human error, the victim may pursue a claim based on the driver’s negligence. When the car was driving itself and the driver did nothing wrong, the cause may instead be a defect in the vehicle or its software.

Product liability law already allows injured people to pursue claims against manufacturers for defective vehicle components, so these rules apply to automated systems without needing to be rewritten. Claims typically focus on the theories described below.

Design and Manufacturing Defects

A design defect exists when the automated system itself is unreasonably dangerous, such as a sensor setup that cannot reliably detect stopped vehicles. A manufacturing defect affects a specific vehicle, such as a faulty camera, radar unit, or braking component that left the factory damaged.

Software Failures and Inadequate Warnings

Software developers may face liability when coding errors, faulty sensor fusion, or flawed decision-making algorithms cause a collision. Manufacturers may also be liable for failing to clearly warn drivers about when an automated system should not be used.

Courts Are Already Holding Automakers Accountable

In 2025, a Florida jury found Tesla partially responsible for a fatal crash involving a vehicle operating on Autopilot and ordered the company to pay $243 million in damages. Even so, automakers and software companies may not be eager to pay claims, and injured people still need to prove the extent of their losses.

Who Is Responsible If a Waymo or Robotaxi Crashes

Tesla launched its robotaxi service in Austin in June 2025, and Waymo operates Level 4 vehicles that carry passengers with no one behind the wheel. When one of these vehicles causes a crash, the company operating the fleet is usually the first place to look, along with the manufacturer and the developer of the driving system. Passengers also have specific rights after a Waymo accident that are worth knowing before they speak with an insurer.

Texas now regulates these services in much the same way as rideshare companies. Under changes to state law that took effect in September 2025, an automated vehicle used for prearranged rides is considered a transportation network company driver for insurance purposes, and the companies that dispatch them are regulated as transportation network companies. These rules overlap with many issues in Uber and Lyft accident claims.

What Texas Law Says About Self-Driving Cars

Texas updated its automated vehicle rules in 2025. According to the Texas Senate Research Center’s analysis of Senate Bill 2807, when an automated driving system is engaged, the system itself is the operator of the vehicle for purposes of traffic and motor vehicle laws, and the owner or authorized company receives any citation. The law also requires automated vehicles to carry liability coverage or self-insurance at least equal to what state or federal law requires, and companies must obtain authorization from the Texas Department of Motor Vehicles before running driverless commercial service.

These rules govern traffic compliance and insurance, but they do not by themselves decide who pays for your injuries in a civil claim. That question still turns on negligence and product liability principles. Texas follows proportionate responsibility rules, so your compensation may be reduced by your share of fault and barred if you are found more than 50 percent responsible. Most claims must also be filed within the two-year Texas statute of limitations for personal injury, so timing matters from the start.

How Insurance and Payment Work After an Autonomous Vehicle Crash

If liability shifts, insurance may shift with it, and the RAND study suggests coverage could change over time. Today, the source of payment usually depends on who caused the crash: the driver’s own auto policy when the driver was negligent, the manufacturer’s coverage when a defect was responsible, or a fleet operator’s commercial policy when a robotaxi was involved.

When more than one party shares fault, their insurers often dispute who should pay and may seek reimbursement from one another later. That process can delay your claim, and negotiating with insurance adjusters may prove as difficult as ever when a large corporation is on the other side.

Evidence That Determines Fault in a Self-Driving Car Crash

Autonomous vehicle crashes generate far more electronic evidence than conventional collisions. Rather than relying solely on driver statements, investigators and attorneys rely heavily on the data the vehicle recorded before, during, and after impact.

Event Data and System Logs

The event data recorder, often called a black box, captures speed, braking, steering inputs, and system status in the seconds before a crash. Software logs show what the automated system perceived, what it predicted, and what action it chose.

Camera, Sensor, and Update Records

Lidar, radar, and camera recordings reveal what the vehicle detected and whether it interpreted its surroundings correctly. Over-the-air update records can show whether a recent software change altered how the system behaved.

Engineering Analysis and Evidence Preservation

Engineers and accident reconstruction professionals can analyze this data to determine whether the system met the manufacturer’s own performance standards. Because companies control much of this information and systems can be updated after a crash, an attorney may send a preservation letter early to protect it.

What to Do After a Self-Driving Car Crash in Texas

Your first priority is medical care, even if your injuries seem minor, because some symptoms appear hours or days later. Call law enforcement, request a crash report, and, if you can do so safely, note whether the vehicle appeared to be in an automated mode and whether anyone was in the driver’s seat.

Avoid speculating about fault at the scene, and do not attempt to access or change any vehicle’s software or data. Before giving a recorded statement to an insurer or the company that operates the vehicle, consider speaking with a personal injury attorney who can explain your options. Whether a vehicle is driverless or not, liability can always be contested after a crash.
