Self-Driving Trucks Are Now Officially Testing on California Highways

It is no longer a concept or a pilot program. Self-driving trucks are now officially operating on California highways with no human driver in the cab.

The California Department of Motor Vehicles granted permits allowing multiple companies to test fully autonomous commercial trucks on public roads. These are not passenger vehicles with a safety driver, they are 18-wheelers running freight routes without a single person on board.

How It Works

The trucks use a combination of lidar, cameras, radar, and AI systems to navigate highway driving. They are currently limited to specific highway corridors and operate primarily during off-peak hours. A remote operations center monitors each truck in real time and can take control if the system encounters something it cannot handle.

Companies involved include Aurora Innovation and several others who have been testing with safety drivers for years. The removal of the human backup driver is the milestone that changes the economics entirely.

What It Means for Workers

The trucking industry employs roughly 3.5 million drivers in the United States. Industry groups say autonomous trucks will handle long-haul highway segments while humans continue doing local deliveries and complex urban routes. Critics say that framing is temporary and that full automation is the obvious end goal.

For now, the trucks are limited in where and when they can operate. But the precedent is set. California approving driverless commercial vehicles on public highways signals that the regulatory barriers are falling faster than many expected.
