"Self-driving technology can transport people and things much more safely than we do today and reduce the thousands of trucking-related deaths each year," a Waymo spokesperson told Buzzfeed.
"We're taking our eight years of experience in building self-driving hardware and software and conducting a technical exploration into how our technology can integrate into a truck," the spokesperson continued.
Waymo confirmed that it is testing a truck, adding that it was manually driving the semi on a public road to collect data. Waymo is only testing one truck.
Alphabet began working on self-driving cars in 2009. It spun out its self-driving car program into a new company called Waymo in 2016.
