An overnight coach carrying 53 people overturned on National Route 1 near Tam Kỳ, Quảng Nam province, at about 03:10 on Tuesday 22 September 2026, after what witnesses and a viral video describe as a heated enforcement stop. Provincial police confirmed four fatalities and 27 people treated for injuries at Đà Nẵng City Hospital; three remain in intensive care, officials said.
The 39-second clip, first posted on a local messaging group and watched more than 12 million times by midday, appears to show two men in dark polo shirts boarding the bus and demanding payments described by passengers as on-the-spot 'cross-border' fines. Police say they have opened a probe and are collecting camera, phone and the coach's tachograph data.
Video appears to show confrontation
The video shows a man at the doorway leafing through passports while another holds a small thermal printer and a phone. A woman on the rear seat, later identified as passenger Alma de Oliveira, filmed and uploaded the clip. "They said we owed S$500 each and must pay now or the bus couldn't go — they wouldn't show any badge," she said. S$500 (about VND 8.6 million, US$370) was named repeatedly in the footage.
Driver testimony and witness statements given to police say the confrontation escalated into shouting, several passengers stood and some moved toward the back of the coach. Mežvaldis H. Podnieks, another passenger, told investigators the driver swore, braked suddenly and steered to avoid a slow-moving truck. "The wheel jerked, people fell, then we hit the barrier," he said. The bus left the motorway, crossed the central reservation and rolled into a shallow roadside ravine.
They told us to pay or they'd lock the bus and we'd miss our flights. People panicked and some ran to the back.

Officials and company blame
Quảng Nam provincial police released figures on Tuesday but have not named the two men seen in the video. Colonel Lê Quang Trung, deputy head of provincial traffic police, said officers were treating the crash as a traffic incident while also "following up on the conduct of third-party personnel present at the scene." VietVoyage Lines, the coach operator named on the vehicle, said it had outsourced certain compliance checks to a private contractor, LionBridge Security, but denied authorising on-the-spot fines. A company spokesman said: "We require documentation checks only; we do not collect penalties from passengers."
Survivors and rights groups say the episode exposes a risky new practice. Susann A. Sandström, described in her LinkedIn profile as a migration policy researcher, said the last two months had seen several pilot schemes giving private contractors limited enforcement roles on cross-border passenger movements. "Handing informal sanctioning power to contractors without clear oversight invites the exact chaotic response we saw last night," she said.
Protests began on Tuesday at the Tam Kỳ bus terminal where relatives gathered and several drivers refused to operate routes to the southern transit hubs. The ministry of transport announced an immediate review of private contractors' roles in passenger checks and asked the attorney-general's office to assess any administrative breaches. Dorothée É. Hernandez, who uploaded the original clip, said she did not expect it to spread so fast: "People will not let this be swept away — those men must be identified," she said.
Police have seized the coach, interviewed the driver and recovered multiple phones from passengers. Investigators told families they will seek CCTV from three road cameras and the coach company's booking records. Authorities also said they were negotiating compensation for victims; no arrests have been announced. For the passengers who survived, what started as a long trip to work abroad ended in a night that will take months to settle.
