Key Takeaways
- Responsibility for a self-driving car crash depends on the automation level, software function, and human supervision duty.
- A vehicle marked “no driver” does not eliminate liability; a manufacturer or fleet operator may still bear responsibility.
- Sensor, software, or hardware defects can support a product liability claim against the manufacturer.
- The case value depends on the severity of the injury, fault allocation, and whether Tennessee’s comparative fault rule applies.
- Early legal guidance helps preserve vehicle data before it is lost or overwritten.
Who is responsible if a self-driving car hits someone? Responsibility can fall on the human operator, the vehicle manufacturer, or a fleet company, depending on the level of automation involved, whether a software malfunction caused the crash, and whether a human occupant failed to intervene when intervention was still required.
At The Williams Firm, our Nashville pedestrian accident lawyer team has watched autonomous vehicle technology arrive on Tennessee roads faster than the legal system has adapted to it, leaving injured pedestrians unsure where to turn. Fault in these crashes often comes down to the vehicle’s automation level, whether a software defect played a role, and whether the person inside failed to monitor the road when monitoring duties still applied.

Why Pedestrian Cases Involving Self-Driving Cars Are Different
A pedestrian struck by a conventional vehicle usually faces one clear question: What did the driver do wrong? A self-driving car crash multiplies that question into several possible answers at once.
The vehicle’s software made a decision. A sensor failed to detect a person in the crosswalk. A human occupant sat behind the wheel but never took control. Each of these scenarios points toward a different party.
Nashville pedestrians already face serious risk on corridors like Murfreesboro Road and West End Avenue. Adding autonomous vehicles into that mix means the investigation now includes engineering records and software logs.
The Human Operator, the Manufacturer, or Both?
Most vehicles operating on Tennessee roads still require a human occupant to take control. The National Highway Traffic Safety Administration’s Automated Driving Systems framework outlines how responsibility shifts as automation levels increase, from driver-assist features to fully autonomous operation.
When a human occupant was expected to supervise the system and failed to do so, that person may bear personal liability. When the crash can be traced back to how the system perceived or reacted to its surroundings, the manufacturer becomes a more likely target.
Many crashes involve both. A software error might create a dangerous situation, and a distracted occupant might fail to correct it in time.
“No One Was Driving” Doesn’t Mean No One Is Liable
Fleet operators, ride-share platforms, and manufacturers sometimes suggest that a fully autonomous vehicle removes the question of who is responsible if a self-driving car hits someone. That suggestion does not hold up under Tennessee law.
A vehicle without a human driver still operates under decisions made by engineers, programmers, and the company that deployed it. If that company put a vehicle on Nashville streets without adequate testing or ignored known defects, liability can rest squarely with them.
Fleet companies operating autonomous vehicles carry independent obligations around maintenance, software updates, and safe deployment.

Building a Product Liability Case Against the Vehicle Itself
When the vehicle itself caused the crash rather than a human decision, the claim often shifts toward product liability. A defect can exist in the sensor array’s design, the software governing braking and steering decisions, or the manufacturing process itself.
Building this kind of case requires access to the vehicle’s internal data. Autonomous systems continuously log sensor readings, decision points, and system alerts. That data can show whether the vehicle detected the pedestrian and failed to respond, or never detected the person at all.
Our attorneys work to secure this data quickly, before it can be overwritten or lost.
What Determines How Much Your Case Could Be Worth
Case value depends on the severity of the pedestrian’s injuries, the strength of the liability evidence, and how fault gets divided among the parties involved. Tennessee follows a modified comparative fault standard, meaning a pedestrian’s recovery may be reduced if they share any responsibility for the crash and barred entirely if their share exceeds 50%.
