The California Teamsters have filed a lawsuit opposing new state regulations that approved the use of heavy-duty autonomous trucks.

They also argue that the rules pose an "existential threat" to hundreds of thousands of union jobs. The DMV said that it could not comment on ongoing litigation, although the agency's director Steve Gordon said in April that the
