New local traffic guidelines close loophole that prevented punishment of robot vehicles and tighten testing rules for heavy cars and trucks
The state of California (USA) has approved a change in the law to close a loophole that prevented the punishment of traffic violations committed by driverless vehicles. Effective June 1, 2026, new guidelines from the local Department of Motor Vehicles (DMV) allow fines to be levied directly on manufacturers and carriers, such as Waymo, for violations detected in their autonomous driving systems.
The move responds to growing pressure from local authorities and the public following a series of incidents involving robotaxis, which include collisions, traffic blockades and, most critically, the obstruction of ambulances and fire engines in emergency situations. Until then, the absence of a physical driver made it difficult to issue standardized police citations.

In addition to punitive inspection, the new regulations expand the requirements for the certification of tests on public roads. Light vehicles will now need to complete a 50,000-mile (about 80,000 km) stage of driving without serious incidents per certification stage. For autonomous semi-trailer trucks, the rigor is ten times greater, requiring proof of 500 thousand miles (800 thousand km) to advance in the operational licensing processes.
The state also gains the power to limit the size of fleets and restrict geographic areas of operation if companies do not demonstrate quick responses to systemic failures. Repeated non-compliance with the rules may lead to the immediate suspension of the legal operating license throughout the Californian territory. While the financial impact of the fines is considered symbolic for giants like Waymo parent Alphabet, the real burden lies in the legal certainty and transparency required to keep the technology on the streets.
