Key Takeaways
- A labor union has sued California state agencies over new regulations for heavy-duty autonomous trucks.
- The union argues that the state failed to adequately consider the potential impacts of self-driving trucks on jobs and safety.
- Supporters say autonomous trucks could reduce crashes caused by human error, but concerns remain about safety and accountability.
- Crashes involving autonomous trucks may require investigators to examine electronic records, vehicle software, and the roles of multiple companies to determine responsibility.
Teamsters California has sued the California Department of Motor Vehicles and several other state agencies over new regulations allowing heavy-duty autonomous trucks on public roads. The lawsuit alleges that the DMV bypassed the California Administrative Procedure Act, which governs how state agencies adopt new regulations. The suit claims the state didn’t fully study how the autonomous truck ruling could affect the economy.
California's decision comes as autonomous trucking companies expand operations in other states and federal lawmakers consider national safety standards. The dispute raises questions beyond California, including how driverless trucks should be regulated, their potential impact on trucking jobs, and who should be held responsible when the technology fails.
What Are California's New Autonomous Truck Regulations?
California's new regulations allow manufacturers to apply for permits to operate heavy-duty autonomous trucks, defined as vehicles with a gross vehicle weight rating (GVWR) of 10,001 pounds or more. Before applying for deployment approval, manufacturers must complete 500,000 miles of testing with a safety driver and another 500,000 miles of driverless testing. They must also submit a safety case addressing the vehicle's hardware, software, and operations.
The rules establish additional safety requirements, including procedures for responding to traffic violations, communicating with first responders, and providing access to manual vehicle override systems. The DMV says the regulations strengthen public safety and accountability for autonomous vehicle manufacturers.
Why Are the Teamsters Suing the California DMV?
The Teamsters opposed California's decision to allow heavy-duty driverless trucks, arguing that the technology could threaten jobs and highway safety. The union has also questioned whether state lawmakers, rather than the DMV, should establish the rules.
In its August lawsuit, the union alleges that California failed to adequately assess the economic consequences of the regulations, including their potential impact on more than 200,000 jobs. It also challenges the state's regulatory review process, arguing that the DMV should have conducted a more extensive economic impact analysis. The DMV held public comment periods before adopting the rules, but the union contends that the process did not satisfy applicable legal requirements.
How Could Autonomous Trucks Affect Trucking Jobs?
A 2018 report from the University of California, Berkeley Labor Center estimated that autonomous trucking could eventually eliminate up to 294,000 long-haul driving jobs nationwide. The report also suggested that some drivers could shift into shorter routes, transporting trailers between local destinations and autonomous truck hubs. Those positions may pay less than traditional long-haul trucking jobs. Although the report predates recent advances in autonomous technology, it helps explain labor unions' concerns about the industry's future.
Are Autonomous Trucks Safe?
As the technology advances, federal lawmakers are considering national standards for autonomous commercial vehicles. On May 22, 2026, the U.S. House Transportation and Infrastructure Committee approved the BUILD America 250 Act, which includes a proposed federal regulatory framework for autonomous commercial trucks. The legislation would establish new safety requirements and address federal oversight of the technology.
Fatigue, distracted driving, and speeding can all contribute to serious truck accidents. Supporters of autonomous trucking argue that removing human drivers from certain operations could reduce some of these dangers and improve highway safety. But because of their size and weight, commercial trucks can cause devastating injuries in collisions with smaller vehicles, raising the stakes for the safety of autonomous technology.
Autonomous technology introduces its own challenges, including potential software malfunctions and difficulties handling unexpected road conditions. Strong test performance doesn't guarantee a self-driving truck will operate safely in every situation. States have also taken different approaches to permitting and regulating autonomous vehicles, with California adopting some of the nation's strictest requirements.
Who Is Liable After an Autonomous Truck Accident?
Determining responsibility after a self-driving truck crash can be more complicated than in an accident involving a human driver. Investigators may need to examine the truck's automated driving system and the roles of its manufacturer, the trucking company, and any remote operators involved.
Electronic records could play an important role. Investigators may look at what the truck's cameras and sensors detected, how its software responded to changing traffic conditions, and whether a system malfunction contributed to the collision. Maintenance records, operating procedures, and information about the truck's testing and safety history may also be relevant.
The absence of a driver behind the wheel doesn't eliminate the possibility of negligence or other legal responsibility. A trucking company could face questions about how it maintained or operated the vehicle, while a manufacturer or technology developer could face claims involving defective equipment or software.
For people seriously injured in an autonomous truck accident, identifying the potentially responsible parties may require examining records held by several companies. Those records could become important evidence in a personal injury lawsuit.
Brandon Smith, a partner at Childers, Schlueter & Smith who handles truck accident cases nationwide, says the shift toward autonomous trucking could change how injury claims are pursued.
“When a commercial truck causes a serious injury, the people affected deserve answers and a way to hold the responsible parties accountable. That doesn't change just because the truck is driving itself. What does change is who may be responsible. Instead of focusing primarily on the driver's actions, a lawsuit could involve the trucking company, the vehicle manufacturer, or the company that developed the automated driving system.”
California's lawsuit is one part of a larger debate over the future of autonomous trucking. As more states allow driverless commercial vehicles on their highways, questions about safety, oversight, and accountability after a serious crash will become increasingly important.
