The California Department of Motor Vehicles (DMV) is being sued by the state’s Teamsters union in an effort to halt amended regulations that allow permits to be issued for the testing and operation of heavy-duty autonomous vehicles.
The lawsuit, filed on August 5 in Alameda County Superior Court, alleges that the process through which the DMV implemented regulations governing driverless trucks was so flawed that the rules should be invalidated. In the 34-page complaint, the union is asking the court to overturn the amended regulations, declare that the rules are unclear, and generally prevent their enforcement.
Peter Finn, general vice president of Teamsters California, which represents 250,000 unionized workers, said that new evidence emerges every day showing that Waymo’s robotaxis pose risks to public safety. “Those dangers increase exponentially with trucks that are up to 16 times heavier and traveling at highway speeds,” Finn said.
Teamsters lawsuit puts safety, cybersecurity, privacy and economic consequences at the center
On April 28, the DMV approved new regulations allowing autonomous freight vehicles weighing 10,001 pounds or more to operate in California. While the agency defended the measure as a step forward for safety, transparency and the state’s leadership in autonomous vehicle technology, Teamsters argues that its potential economic consequences were not adequately assessed.
The lawsuit also alleges that the DMV avoided conducting the Standardized Regulatory Impact Analysis, which is required when a regulation could generate an economic impact of more than $50 million during its first year.

According to the lawsuit, the expansion of autonomous trucks could put more than 200,000 truck-driving jobs at risk, while also affecting independent drivers and transportation-related businesses across California, including commercial driving schools, hotels, restaurants and truck stops.
These concerns are compounded by questions surrounding the safety, cybersecurity, privacy and transparency of autonomous systems. Teamsters and other industry organizations argue that significant questions remain about whether these vehicles can operate safely without constant human supervision.
According to a Teamsters press release, a recent poll found that four out of five California voters support legislation requiring a human safety operator to be present at all times in autonomous trucks and delivery vehicles operating in the state.
“The safest operator of an 80,000-pound commercial vehicle on America’s highways is a well-trained, professional human truck driver,” said Todd Spencer, president of the Owner-Operator Independent Drivers Association (OOIDA).

California: A strategic market for autonomous trucking companies
The lawsuit also highlights California’s importance to the transportation industry. The state handles a significant share of U.S. international trade, making it a strategic market for companies developing autonomous trucks.
Teamsters argues that California authorized heavy-duty autonomous trucks without adequately evaluating their economic and labor consequences, particularly the potential displacement of truck drivers and the impact on industries that depend on the trucking sector.
