<div id="readability-page-1"><div> , /PRNewswire/ -- TIER IV, the pioneering force behind open-source software for autonomous driving, has completed proof of concept tests for long-haul autonomous trucking with Yamato Transport Co., Ltd. (Yamato Transport) and Mitsubishi Fuso Truck and Bus Corporation (MFTBC), as part of a Japanese government initiative. The tests evaluated vehicle performance, safety protocols and operational workflows, with customer freight transported on a semi-trailer truck equipped with Level 2+ technology. The data and operational insights gathered will be used to refine autonomous driving technology, with the ultimate goal of integrating Level 4 trucks into Yamato Group's long-haul transportation routes. <img src="https://imageproxy.pbkrs.com/https://mma.prnewswire.com/media/2168831/TIERIV_Logo.jpg?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="400" height="75" original-src="https://imageproxy.pbkrs.com/https://mma.prnewswire.com/media/2168831/TIERIV_Logo.jpg"/> Overview<ul type="disc"><li>Period: February 16-20, 2026</li><li>Route: Haneda Chronogate Base (Tokyo) – Kansai Gateway Base (Osaka).
