A self-driving truck just glided through a spot where even seasoned long-haul drivers ease off and grip the wheel with both hands. Japan’s T2 has taken a leap that felt years away just a couple of seasons ago: its autonomous big rig cleared a highway toll gate — no hands on the wheel, no flip to manual, no safety net.
For a passenger car, that’s a yawn. For a 2.5-metre-wide tractor squeezing into a corridor barely three metres across, it’s an engineering exam with almost no margin on either side. Curbs, gear, a gate, and zero room for error.
The run used a Level 2 truck, but T2 is already aiming squarely at Level 4 — the moment the cab no longer needs a human in it at all. The tests went down in May 2026 at two points at once: Ayase Smart IC on the Tomei Expressway in Kanagawa, and Nishinomiya-kita IC on the Chugoku Expressway in Hyogo.
How did the rig even fit? A combo of pre-mapped, high-precision 3D data and on-board LiDAR. The system matched live sensor reads against the stored map on the fly and held its line within centimetres. On top of that, the truck was taught to read the ETC gate itself — so it could decide on its own whether to push through, instead of nosing into a closed barrier.
T2 isn’t just building a truck. It’s building a chain. The hubs in the middle are called “transgates” — terminals where a flesh-and-blood driver climbs in or out. On the highway, the truck runs itself; on the surface streets to a warehouse or customer, a human takes the wheel. Alongside the already-running Transgate Ayase, the company has opened Transgate Nishinomiya-kita next to the matching interchange. The new site sits on Kuramoto Transport’s yards and can handle up to eight trucks at once.
T2 has been running commercial loads on part of the Kanto–Kansai corridor since 2025, and its client list across carriers and manufacturers has now grown to 17. In March 2026, the company logged another milestone: its truck ran roughly 500 km between the two regions without the driver touching the steering wheel even once.
The next frontier isn’t the highway itself. It’s the grey zone: the stretch from the toll gate to the transgate, the on- and off-ramp into the yard. That’s exactly where the driverless chain still snaps today. The moment the rig handles that whole loop without a single manual handoff, autonomous logistics stops being a demo. It becomes a route.
