A trailer-truck driver died after the vehicle overturned and caught fire on the steep Highway 304 descent in Na Di district, Prachin Buri, early on Saturday, 18 July. Police believe brake failure caused the crash at kilometre marker 209. The truck, which was carrying compressed natural rubber blocks, was travelling from Nakhon Ratchasima towards Kabin Buri when it lost braking power on the final sharp curve before the downhill section, according to Wang Khon Daeng police. It overturned against a concrete median barrier and was quickly engulfed by flames. Thick black smoke rose from the truck as the rubber cargo burned. Driver could not be identified immediately Police, firefighters, rescue teams and highway officials arrived shortly after half past midnight. Firefighters needed more than an hour to bring the blaze under control. Compressed natural rubber blocks are highly combustible, police said, which caused Saturday's fire to spread rapidly and trapped the driver inside the cab. Once the fire was out, rescuers found one body trapped in the cab. The victim had suffered severe burns, meaning neither the person's identity nor gender could immediately be established. Rescue workers used hydraulic cutting equipment to remove the body. It was taken to Na Di Hospital for forensic identification. The lorry had Bangkok licence plates. The crash blocked all Bangkok-bound lanes through the morning, creating traffic queues stretching for several kilometres. A hazardous route between national parks The crash happened on the hilly Highway 304 section between the Unesco-listed Khao Yai and Thap Lan national parks, an area known for steep gradients and sharp bends. The downhill stretch between kilometre markers 208 and 210 has long been considered among Thailand's most dangerous roads. It has a prolonged gradient of 4-6% and tight curves, and heavy vehicles unfamiliar with the route have frequently suffered brake failure there. Previous fatal crashes The same stretch has been the scene of major fatal crashes. On 26 February 2025, a study-tour bus from Bueng Kan left the road after brake failure, killing 19 people and injuring 30. In February 2014, 15 people died and 45 were injured when a tour bus carrying schoolgirls and their teachers hit the rear of a loaded 18-wheel truck.
