Who Is at Fault in a Self-Driving Car Accident?

Fault in a self-driving car accident is determined by examining what caused the crash, rather than simply whether an automated driving system was active. Depending on the circumstances, responsibility may rest with a human driver who failed to supervise or intervene, another road user, the vehicle manufacturer, a software or component developer, a maintenance provider, or several parties. If defective sensors or software caused the vehicle to make an unsafe maneuver, product liability principles may apply. If the system required the driver to pay attention and the driver ignored warnings or failed to intervene, the driver may share responsibility. Evidence can include event data, camera footage, sensor logs, software records, maintenance records, and witness accounts.

Automated vehicle laws and regulations vary by state and continue to evolve. Determining fault may therefore require both traditional accident reconstruction and specialized technical analysis of the vehicle’s autonomous system and its expected capabilities.
