Who Is Responsible in a Car Accident Involving a Self‑Driving Car Like Waymo?

As self-driving vehicles become more common on California roads, questions about liability are becoming increasingly important—especially in major cities like Los Angeles where autonomous vehicles (AVs) are already being tested and deployed. If you are involved in a car accident with a self-driving car such as a Waymo vehicle, the question becomes: Who is legally responsible?

Understanding How Self‑Driving Cars Work

Self-driving cars operate using advanced technology—cameras, sensors, artificial intelligence, and detailed mapping systems. While these vehicles are designed to reduce human error, accidents still happen. When they do, determining fault can be more complex than in a traditional collision.

Potentially Liable Parties in a Waymo Accident

Several parties may be legally responsible depending on what caused the collision:

1. The Autonomous Vehicle Company (e.g., Waymo)

If the crash resulted from a system malfunction, defective software, faulty sensors, mapping issues, or any other technological failure, the company operating or developing the AV could be liable. This is similar to a product liability claim.

2. The Human “Safety Driver” (If One Is Present)

Some self-driving cars still use backup drivers who must take control in emergencies. If the safety driver failed to intervene or acted negligently, they may share responsibility.

3. The Other Driver(s) Involved

If a human driver—yourself or another motorist—acted carelessly (e.g., speeding, illegal turns, distractions), they may still be at fault. Self-driving cars are not free from the rules of the road; they must still react to human drivers.

4. The Vehicle’s Manufacturer or Component Makers

If the crash was caused by a defective part—like braking systems, tires, or sensors—the manufacturer of that part can be held responsible under product liability laws.

5. Government Entities

In rare cases, unsafe road conditions, inadequate signage, or poor roadway design may make a city or government agency liable.

How Fault Is Determined in Autonomous Vehicle Accidents

Investigating an AV accident often involves reviewing:

• Onboard data logs (“black box” records)
• Video footage from the car’s cameras
• Vehicle sensor data
• Software diagnostics
• Statements from safety drivers or witnesses
• Police reports

Because these vehicles collect massive amounts of data, determining liability may require legal expertise, technical analysis, and sometimes litigation to obtain company records.

Your Rights After an AV Crash

If you were injured in a collision with a self-driving car like Waymo, you may be entitled to compensation for:

• Medical bills
• Lost wages
• Pain and suffering
• Vehicle repairs
• Long-term care needs

However, AV companies and insurers often try to shift blame or minimize payouts—making strong legal representation essential.
