The bus driver later admitted to authorities that he had been feeling drowsy at the wheel.

The collision occurred at around 2:15 a.m. as Doan Minh Quang, 42, was driving the passenger bus on the Phan Thiet-Dau Giay Expressway.

As the bus reached a section in Lam Dong Province, it slammed into the rear of a truck that had stopped in the emergency lane.
