Regarding the fire incident involving a truck on Thepharak Road (Bangna–Trad) near km. 40+500 on 3 May 2026 at approximately 19:30, the fire was intense due to the lithium batteries, causing high heat and continuous explosions. Flames from the incident affected parts of the concrete surface on the Burapha Withi Expressway. Subsequently, the Expressway Authority of Thailand ordered engineers and expert technicians to inspect the damage and carry out necessary repairs. They confirmed that the Burapha Withi Expressway could resume normal operations, as previously reported.
At 15:00 on 4 May 2026, Pol. Col. Somchai Yusawat, Deputy Commander of the Chachoengsao Provincial Police, along with officers from Bang Pakong and Plaeng Yao police stations, presented a court warrant to a scrap purchasing factory in Plaeng Yao District. This followed leads from the transport department indicating that the truck involved in the fire had loaded cargo from this factory, destined for Samut Sakhon Province.
Initially, during the joint operation involving police, industry officials, the Factory Department, and administrative officers inspecting the factory premises, no irregularities or lithium batteries were found.
