Waymo’s huge autonomous trucks return to the roads of Arizona

Waymo is bringing its autonomous trucks back to Arizona.

The Alphabet-owned company — formerly operated by Google — announced the news in a tweet on Wednesday, May 29.

Waymo has become very familiar with the state’s roads as the state is one of the company’s favorite locations for testing its autonomous cars. Toward the end of last year, for example, it selected Phoenix for the trial launch of its first ridesharing service — Waymo One — using its autonomous Chrysler Pacifica hybrid minivans.

While the team has been developing autonomous cars for the last 10 years, its interest in self-driving trucks is a more recent development. The first tests of its hands-free Class 8 big rig started in Arizona in 2017, and when that trial finished it shifted testing to Atlanta, Georgia, the following year. Now the team says its trucks will be back on the roads of the Grand Canyon State before the end of this week.

It’s not clear how many trucks are involved, but one thing’s for sure — the big, mighty vehicles will be sticking to the state’s wide and relatively straight freeways rather than heading into cities where the turns might still be a bit too tight for the technology to handle.

“Our software is learning to drive big rigs in much the same way a human driver would after years of driving passenger cars,” Waymo said when it launched its Atlanta trial in 2018. “The principles are the same, but things like braking, turning, and blind spots are different with a fully loaded truck and trailer.” In other words, the custom-built sensors and complex software need to be adapted to suit the size and weight of the trucks to ensure a safe and smooth ride. And rest assured, in the unlikely event that any of the trucks get into difficulty while they’re out and about, a “highly trained driver” will be behind the wheel, ready to take control.

In Atlanta, Waymo’s self-driving truck tests transported freight for Google data centers, but it hasn’t said if the Arizona trucks will be put to work, too.

Waymo is one of a number of players developing autonomous trucks. San Diego-based TuSimple, for example, recently announced a partnership with the USPS to transport mail across several states using its autonomous big rigs, while Volvo has been looking at how it might use different kinds of self-driving trucks for specific tasks.

Uber, on the other hand, ditched its autonomous-truck program in July 2018, saying it wanted to focus on developing its self-driving car instead.

Polestar forced to exit the US market. It’s a shame we won’t see its refined design anymore
Boring EVs caught a break as Americans lose Polestar
polestar-3-ev

Polestar, the Swedish EV brand controlled by China’s Geely, has been denied authorization under the US Connected Vehicle Rule. As a result, it will not be able to sell vehicles in the US from the 2027 model year onward. The company is not disappearing from American roads overnight. Polestar says it will continue selling existing US inventory of the Polestar 3 and Polestar 4, and current owners will still have access to service support. But for future models, the door is effectively closing unless something changes.

The Wild West era of robotaxis is starting to end
New global rules could replace patchwork regulation with stricter safety proof for driverless fleets.
Self driving car from Waymo

Robotaxi rules have entered their first global phase. A UN vehicle standards forum has adopted the first international framework for fully autonomous vehicles, giving driverless fleets a common safety baseline across major markets.

The move lands while robotaxis are expanding from test programs into a bigger commercial race. In the US and China, private fleets more than doubled in 2025 to 8,000 vehicles across more than two dozen major cities.

Google Meet on Android Auto

Android Auto is finally getting Google Meet, months after the video conferencing app made its debut on Apple CarPlay. Android users can now pull up scheduled meetings and dial recent contacts straight from their car's display instead of reaching for their phone.
