AB 2193 California Assembly · 2025-2026 Regular Session

Autonomous vehicles.

Summary
Existing law authorizes the operation of an autonomous vehicle on public roads for testing purposes by a driver who possesses the proper class of license for the type of vehicle operated if specified requirements are satisfied. Existing law prohibits the operation of an autonomous vehicle on public roads until the manufacturer submits an application to the Department of Motor Vehicles, as specified, and that application is approved. Existing law requires the department to adopt regulations setting forth requirements for the submission and approval of an application, including, among other things, any testing, equipment, and performance standards the department concludes are necessary to ensure the safe operation of autonomous vehicles on public roads, as specified. Existing law authorizes a peace officer, as defined, to issue a notice of autonomous vehicle noncompliance upon observing an alleged violation of the Vehicle Code or upon observing an alleged violation of a local traffic ordinance adopted pursuant to the Vehicle Code by an autonomous vehicle while the autonomous technology is engaged. This bill would require a citation for a traffic violation by a level 4 or 5 autonomous vehicle to be issued to the manufacturer of the autonomous technology if a traffic violation was committed while either the vehicle did not have a person in the driver's seat or the vehicle had a person in the driver's seat and the autonomous technology was engaged. The bill would authorize those citations to be issued by first-class mail. The bill would require a citation to be issued to the driver of an autonomous vehicle of any level if a traffic violation was committed while there was a person in the driver's seat and the autonomous technology was not engaged. The bill would require a citation to be issued to the driver of a level 3 autonomous vehicle if a traffic violation was committed while there was a person in the driver's seat and the autonomous technology was engaged. The bill would authorize the driver to, as a defense, raise that the autonomous technology was responsible for the traffic violation. The bill would require the citation to be issued to the manufacturer of the autonomous technology if the court determines that a level 3 autonomous vehicle was the cause of the traffic violation. The bill would authorize the holder of the testing permit or deployment permit to contest a citation or penalty.

MODERATE
AB 2193 was amended to add a co-author (Assembly Member Davies) and, most significantly, to introduce a tiered citation liability framework for autonomous vehicles based on their SAE autonomy level. For Level 4 and 5 vehicles, traffic citations are now directed at the manufacturer of the autonomous technology when the technology is engaged or no person is in the driver's seat. For Level 3 vehicles, the driver remains initially liable but gains a new defense to shift liability to the manufacturer if the court finds the autonomous technology caused the violation.
REQUIREMENT

New citation rule for Level 4 and 5 autonomous vehicles: if no person is in the driver's seat or if a person is present and the autonomous technology is engaged, the traffic citation must be issued to the manufacturer of the autonomous technology rather than the registered owner or driver.

New citation rule for Level 3 autonomous vehicles: the citation is initially issued to the driver, but the driver may raise as a defense that the autonomous technology was responsible for the violation. If the court determines the autonomous technology caused the violation, the citation is reissued to the manufacturer.

New rule clarifying that for any level of autonomous vehicle, if a person is in the driver's seat and the autonomous technology is NOT engaged, the citation goes to the driver.

ENFORCEMENT

Citations issued to manufacturers for Level 4 or 5 autonomous vehicles may be sent by first-class mail specifically.

SCOPE

The bill's scope expanded from a simple owner/driver citation framework to a multi-tiered system that assigns liability differently based on the SAE autonomy level (3, 4, or 5) of the vehicle and whether the autonomous technology was engaged at the time of the violation.

TECHNICAL

Assembly Member Davies added as co-author of the bill.
