TIER IV has successfully conducted proof of concept tests for long-haul autonomous trucking in collaboration with Yamato Transport and Mitsubishi Fuso. The tests, part of a Japanese government initiative, evaluated vehicle performance and safety using a semi-trailer truck equipped with Level 2+ technology. The trials took place from February 16-20, 2026, covering a 500-km route between Tokyo and Osaka. Insights gained will help refine autonomous driving technology, aiming for the integration of Level 4 trucks into Yamato's logistics operations.
