Thailand's government will open two new motorway segments for free trial use in late August 2026: M6 (Bang Pa-in–Pak Chong, 110 km) opening Friday 21 August, weekends only, 12:00 Fri–24:00 Sun, cars only, max 80 km/h; and M82 (Bang Khun Thian–Ban Phaew, 16.4 km additional segment) opening Friday 28 August, 24 hours daily, vehicles/trucks/buses allowed, max 80/65 km/h respectively. Different hours and entry/exit gates apply due to ongoing construction. Users should verify conditions before travel to ensure fuel/battery sufficiency and avoid restrictions (no motorcycles/non-motorized traffic on M82).
