Starsky envisions trucks driving autonomously on the freeway, but having a human driver driving the truck remotely at the beginning and end of the trip.
The trucks will have safety drivers on board to monitor the various systems and take control if needed.
The firm said that the software used to drive the big trucks is the same as that which drives the company's cars; the lorries also use the same suite of sensors that power Waymo's self-driving minivan.
This pilot, in partnership with Google's logistics team, allows for the further development of Waymo's technology and integrate it into the operations of shippers and carriers, with their network of distribution centers, ports and terminals.
"Our software is learning to drive big rigs in much the same way a human driver would after years of driving passenger cars", the company said in a blog post. Although the basic principles of driving remain the same, driving a truck that's loaded down with cargo is trickier due to its size and different ways of handling.
Korea mulls entering new Pacific trade pact
The revised pact keeps most of the provisions, including tariff reductions, agreed in 2016 when USA was still a member. New Zealand, Japan, Canada, Mexico, Chile and Australia will all grow by an additional 1% or less.
Also in January, Waymo said it would start testing its minivans in Atlanta to experiment with driving in the city's dense traffic and high summer temperatures.
Today's announcement comes a couple of weeks after Waymo announced its self-driving cars had covered 5 million miles on public roads. The other three companies we've mentioned-Uber, Starsky, and Embark-have all focused on freeway driving, which is generally considered the easiest type of driving to automate.
Waymo joins Uber and Tesla in the race to develop autonomous trucks and disrupt the traditional trucking industry.
The race is heating up to remove the driver and get autonomous freight trucks on the road.
Waymo's trucks will have plenty of competition.
Waymo believes self-driving technology has the potential to make this sector safer and more efficient.
