The semi slammed into the home at 6:45 p.m. in the 900 block of Sacramento Avenue in Spring Valley.
A tractor trailer rolled through a fence and into a Spring Valley house Tuesday night.
“Disaster, disaster,” said resident Anna Lewis.
Lewis and her boyfriend were in their living room around 6:45 p.m. when the truck rolled down the street and into the home on Sacramento Avenue in Spring Valley.
“I was thinking about going into the kitchen a few minutes before that, I was thinking about dinner you know so I was really glad I wasn't there,” she said.
"I guess it was a big boom but when it happened I didn't think about that…I was worried about fires or something.”
The truck apparently rolled to the house from West Coast Iron, Inc., the steel company across the street. The homeowner told NBC 7 San Diego the brake wasn’t on properly.
“I was worried that a car could always come by here and go in the house but I didn't think it would come from the steel yard,” Lewis told NBC 7 San Diego.
