Mindy Tran didn't think twice when she saw her car rolling down the driveway with her 2-year-old twin girls buckled in the back seat.
In fact, she literally sprang into action.
"I had to use myself as a speed bump to slow it down enough for one of my neighbors to get in and completely stop the car," Tran tells WCVB.com.
The 22-year-old mother, who had just moved to a new apartment in Lawrence, Mass., parked her car in the garage and got out to lock her front door. It was then that she saw the car start moving, she tells the news site.
Trying to prevent the car from rolling down into a traffic-heavy street, she recalls, "My first instinct is, 'I have to push the car back into the driveway.'"
As a result, Tran's left knee was crushed and her right leg dislocated during the March 6 incident.
Neighbors, however, rushed over to help and stopped the car, getting the girls to safety in the process.
Firefighters also arrived and used wooden blocks to stabilize the car. They also used an airbag to lift the car off of Tran, according to the site.
"It was all for my kids," Tran tells WCVB. "I'm just glad my kids are fine."
