A "platoon" of trucks driven by smart technology has arrived in the Dutch city of Rotterdam after crossing Europe.
The concept of truck platooning involves a set of vehicles, connected by WiFi, driving in a "column."
The truck at the head of the column sets both the speed and route of those behind it, with synchronized breaking and shorter gaps between the trucks two key features.
Driving in this way helps to reduce CO2 emissions and provides up to ten percent of savings on fuel, according to the organizers of the trial.
"The results of this first ever major try-out in Europe are promising," Melanie Schultz van Haegen, the Netherlands' minister of infrastructure and the environment, said in a news release.
"Truck platooning ensures that transport is cleaner and more efficient. Self-driving vehicles also improve traffic safety because most traffic accidents are due to human error," she added.
