Car manufacturer Daimler has been road-testing its autonomous trucks in Nevada since May, hoping to test self-driving trucks on German motorways this year.
Daimler was positive that the firm would get certification within weeks seeking approval to operate the vehicles near the city of Stuttgart.
"We're testing in Germany on our own proving grounds. The next step is getting real-life experience on German highways as well," a spokesman told the BBC. "We're looking to do that in the second half of the year."
He added that the system could be thought of as comparable to autopilot technology already in use on aircraft.
Daimler's autonomous trucks use a combination of radar, lasers and camera systems to identify obstacles and the boundaries of the road. Therefore, the company believes that the truck driving by itself is safer and more efficient.
Daimler says that a human driver is always present and able to retake control of the truck immediately if required.
Alan Stevens, a transport expert at the Transport Research Laboratory, said developing the technology is the "right direction" to be going in as there is a strong business case for fully autonomous trucks.
