Nguyen Xuan Dong, 52, was driving the bus carrying 26 people on National Highway 14 in the Central Highlands province when he decided to turn into a house to avoid a truck at a T-junction at around noon.
There were no one side the house at the time, but one of its walls was knocked down. Dong and a passenger died while an assistant driver and four other passengers were injured.
Locals said there are no red lights at the T-junction, which is at a sloping section of the road, causing accidents to happen regularly.
