Drone trucks could soon be plying US highways after Nevada authorities on Wednesday granted a license to test self-driving trucks on public roads.

While companies such as Google and luxury brands like Lexus have dominated the headlines with advances in driverless cars, Daimler board member Wolfgang Bernhard told reporters autonomous trucks were likely to hit the roads first.

Daimler’s 18-wheel Inspiration has now been certified for use on public roads in the state, and yesterday the non-human (well, less-human) big rig rolled out across the Hoover Dam, negotiating some (but not all) turns and twists all by itself. For the tougher curves, it had some help from a driver inside the cab.

Google’s own automated car is also licensed for use in Nevada; both the Daimler truck and the Google car are authorized for use under Nevada’s autonomous driving law, which “requires that drivers obtain a special endorsement on their driver’s licenses” according to the National Highway Traffic Safety Administration.

Bernhard told reporters in Las Vegas that because trucks operate in “a less complicated traffic environment” they were ideal starting points for the coming automated vehicle market. But the real economic value of the invention, he said, would come when not just Nevada but other contiguous states license the vehicles, enabling trucking companies to use them to transport goods across long distances.

The licensing process was a lengthy one, said a Nevada department of motor vehicles spokesman, David Sierro. “I’m just getting out of the truck now,” he told the Guardian. “You’re talking about a series of different technologies; crash avoidance, blindsight, camera technology,” he said. “Rather than being a single autonomous [device] it’s a series of technologies they’re developing. They’re building it in an incremental way.”

Sierro said Daimler tested the truck on areas like the Las Vegas Motor Speedway, where the trucks could read pavement markings without endangering other drivers or pedestrians. “It’s fascinating to see how it’s reading the lines,” Sierro said. “When there’s something [too complex for the autopilot] coming up, there’s a warning that lets the driver know he’s going to have to take over.”

Tony Illia, of the Nevada department of transportation, said the state gave Daimler the option to start out simply. “There are huge stretches of empty, government-owned land [in Nevada],” he said. “Our population is centered in the Reno area and the Las Vegas area”, so trucks going between the two mostly have to navigate long straightaways. Daimler had a request of the Nevada government, too: “The one thing [Daimler] did ask was to brighten up the lane-striping and the buttons, to make sure they were clean and bright,” Illia said. “I think that helps the cameras on the truck.”

Still, there’s a lot more to be done before the truck makes any deliveries. Simonette Illi, a spokeswoman for Daimler, told the Guardian that the trucks should be available for purchase “from the middle of the coming decade (around 2025)” and that it’s important to have it available “at an attractive price”.

“We consider a payback period of 18 to 24 months for our customers when the new technology goes into production,” she wrote.

Companies like Lowell, Arkansas-based JB Hunt have reported a driver shortage across the country and are looking at consolidation in order to meet demand. The company is also worried about changing emissions standards for Class 8 trucks (that’s the class of truck demoed today, which Daimler says is more efficient), so a vehicle with a driver who has to do less work, or requires no driver at all, could provide companies like Hunt with a cost savings on labor.

A spokeswoman for JB Hunt declined to comment for this story.
