A young man who lived in the home, spoke through a translator, describing the moment of impact.
"He was just in his room when he heard the noise, very loud, he run quick to the front door and saw the car right there and his grandmother was there too," Ngoc Tran said through a translator.
He said he was scared the house was going to collapse and was worried about his grandmother, who banged her head.
The grandmother was transported to the hospital and is expected to be okay.
