Aurora Adds Human Back to Autonomous Trucks at Paccar’s Request

Less than three weeks after launching its first commercial self-driving truck operations in Texas, Aurora Innovation has announced a significant operational change: a human observer will now sit in the driver’s seat of its autonomous vehicles. The decision comes at the request of truck manufacturer Paccar Inc., which builds the vehicles Aurora is using.

Aurora CEO Chris Urmson confirmed the change in a company blog post on May 16, stating that although the Aurora Driver autonomous system remains in full control of the vehicles, the observer will be seated up front and ready to intervene if necessary.

“We are confident this is not required to operate the truck safely,” Urmson wrote, citing the company’s rigorous safety validation that included nearly 10,000 requirements and 2.7 million individual tests. “Paccar is a longtime partner and, after much consideration, we respected their request.”

Shift Follows Initial Launch of Driverless Operations

Aurora had announced the start of fully driverless freight hauling on May 1, operating two Paccar-built trucks without a human in the driver’s seat. That milestone marked the company's first commercial driverless operations on public roads.

The new operational model—with a human back in the driver’s seat—marks a notable revision of that announcement. Aurora said the decision was specifically tied to the use of certain prototype parts in the trucks, suggesting that Paccar required additional precautions during the early stages of commercialization.

Mounting Scrutiny and Organizational Changes

Aurora’s revision also comes amid rising external scrutiny. A report from short seller Bleecker Street Research on May 14 alleged that Aurora had not yet secured formal approval from Paccar to commercialize autonomous driving features in its trucks, and that the manufacturer believed the timeline for readiness was longer than publicly communicated.

Aurora declined to comment on the report. The company has also experienced executive turnover in recent months. Sterling Anderson, Aurora’s co-founder and Chief Product Officer, is departing to join General Motors in the same role. Other recent exits include General Counsel Nolan Shenai and former Senior Vice President of Engineering Yanbing Li.

Expansion Plans Still on Track

Despite the adjustment in Texas, Aurora remains committed to expanding its autonomous freight network. The company plans to add routes to El Paso and Phoenix by the end of 2025.

While the addition of a human operator may be viewed as a step back in terms of autonomy, Aurora framed it as a pragmatic decision that supports ongoing partnership and safety assurance. The company emphasized that its long-term vision of fully autonomous commercial trucking remains unchanged.
