The American transport company have retired their Otto brand and are now focusing all their energy into creating the autonomous vehicle under the Uber ATG name.
They said in a statement: "Long-haul commercial trucks are responsible for delivering nearly 70% of goods in America, yet the highways they're driving on see hundreds of thousands of preventable accidents each year.
"Uber ATG is committed to creating a new approach to modern transportation - and a large part of that effort is the development of self-driving technology to improve the safety and efficiency of the trucking industry.
"Our self-driving truck effort started in 2016 with the addition of the team from Otto. Since then, we've combined the best of Otto and ATG to build technology for both cars and trucks. With that upgrade, we've retired the Otto name and integrated all of our self-driving efforts into Uber ATG.
"The consistent patterns and predictable road conditions of highway driving, combined with the fact that highways make up only 5% of U.S. roads, make it optimal to deploy self-driving technology. We are working hard to advance our technology and prepare for longer operations. As the demand for freight grows steadily, our team is driven by a sense of urgency to improve our transportation network."
Uber had previously tested a self-driving truck on the roads of Colorado. In 2016, the company delivered a trailer full of Budweiser on a route, which took them 120 miles down a highway.
And self-driving trucks are not the only new vehicles Uber are working on. They recently unveiled plans to create the first flying taxi, which they hope to launch in Dallas and Dubai in 2020.
Uber's chief product officer Jeff Holden said: "Urban Aviation is a natural next step for Uber in this pursuit, which is why we are working to make 'push a button, get a flight' a reality."
