TuSimple completes driverless big-rig truck test in Arizona

That big-rig truck heeding the speed limit and traffic rules between Tucson and metro Phoenix might not have had a human driver operating it at all.

TuSimple Holdings, a public corporation headquartered in San Diego, said it successfully completed an 80-mile run along highways and surface streets, including Interstate 10, from Tucson to a location in the Phoenix area with nobody in the cab.

The company, which has tested autonomous trucks at a facility in Tucson, said the Dec. 22 trial run, conducted at night, was the first involving no human driver in a large commercial vehicle that interacted naturally with motorists on open public roads. Waymo and other companies also have tested self-driving trucks.

No driver, but lots of eyes on road

TuSimple called the Arizona test the “world’s first fully autonomous semi-truck run on open public roads without a human in the vehicle and without human intervention.”
