A clip that has amassed nearly 700,000 views on social media captured a dangerous near‑miss on Phạm Hữu Lầu street in the Tân Mỹ ward of Ho Chi Minh City.
The footage, recorded by the dash‑cam of 33‑year‑old driver Phan Mạnh Thuơng, shows a woman on a motorbike carrying a small child riding directly behind a large truck that was reversing to make a U‑turn.
The truck activated its white rear‑directional lights and a warning beacon while turning, yet the motorbike continued to follow the tail, entering the truck’s blind spot.
A second motorcyclist quickly moved to the side, allowing the truck driver to see the situation through his rear‑view mirror and signal a stop.
Meanwhile, a tourist‑car driver behind the truck honked repeatedly, alerting the motorcyclist to the hazard.
Thuơng, who witnessed the incident at the end of August after leaving a charging station, posted the video to warn road users.
He emphasized that a white rear light indicates a vehicle is backing up and urged motorcyclists never to position themselves directly behind a reversing truck.
Viewers responded with calls for mandatory rear‑view cameras on heavy vehicles and reminders that riders, especially those with children, should keep a safe distance from large trucks when they are backing or turning.
The episode has sparked a broader discussion on road safety practices for motorcyclists in Vietnam’s congested urban traffic.
