WANG NAM KHIAO, THAILAND – A routine passenger trip turned into a deadly disaster when a minibus plunged into a ravine on a notorious mountain road, killing two women and injuring 14 others.
Deadly plunge on notorious mountain highway
A white Toyota minibus registered in Bangkok left Highway 304 at kilometre 243 on Monday, 5 January 2026, between Khao Yai and Thap Lan national parks. The vehicle broke through a guardrail and fell more than ten metres into a deep gorge on the winding mountain stretch. It overturned several times and came to rest upside down, leaving a scene described as one of complete destruction.
Rescue in steep terrain
Emergency teams faced extremely difficult conditions as they climbed into the ravine to reach the victims. Fourteen passengers with serious injuries were taken to Pak Thong Chai and Wang Nam Khiao hospitals for treatment. For two women, help came too late and they were pronounced dead at the crash site, leaving families devastated.
Driver says he fell asleep at the wheel
The driver, Danai Prachit, survived the crash and gave investigators under Police Lieutenant Colonel Nakhon Thanomsap a stark account of what had happened.
“I left Pattaya at 5 a.m. At around 10 a.m., on the ascent, I suddenly became tired and lost control,”
said Danai Prachit, minibus driver.
Police said they assumed fatigue was the primary cause of the accident, indicating the driver had apparently not taken sufficient rest breaks. The minibus was seized for technical inspection, and criminal proceedings were initiated against the driver.
High-risk road with a grim record
According to authorities, the crash location was no coincidence, as the stretch was notorious for serious accidents. Steep drops, tight curves and long, uninterrupted driving on the route between national parks had repeatedly taken a toll. Provincial police chief General Narongsak Phromtha went personally to the scene while investigations continued at full speed.
Fatigue a recurring killer on Thai roads
Officials and observers noted that the case was not an isolated incident, with driver fatigue among the main causes of serious bus crashes in Thailand. Low-cost operators were reported to put drivers under pressure, turning long journeys without breaks into a deadly risk for passengers. Laws on driving and rest times were described as clear on paper, but enforcement was often considered too lax until another tragedy occurred.
Calls for stricter controls and technology
Experts and victim support groups had long demanded tougher rules to improve road safety. They argued that mandatory tachographs and electronic monitoring of rest periods could save lives on demanding routes. Advocates also urged the wider public to be more alert, saying every passenger should pay attention if a driver appeared tired, as two people had already paid with their lives and further consequences were needed to prevent the next bus from plunging into the abyss.
Debate over how to stop “invisible” fatigue
Safety advocates warned that tiredness remained an invisible but lethal threat, especially on steep, winding mountain roads. They questioned whether appeals to drivers alone were enough, or whether much stricter rest-time rules, checks and technical assistance were required. They also raised the issue of when micro-sleep at the wheel would finally be treated as seriously as drink-driving in both law and enforcement.
