A young mother crushed one of her legs and dislocated the other one two weeks ago, in an effort to save her twins from inside her car as it rolled toward traffic.

Mindy Tran, 22, was locking her front door when she noticed her car, with her children inside, was rolling backwards down the driveway towards a busy street.

She said her instincts kicked in as she threw herself onto the ground behind the car, which slowed it down enough for neighbors to get the kids out.

The young mom said even if she never walks again, she knows she would have sacrificed more it if meant keeping her little girls safe.

What an incredibly brave thing to do.  A mother's instincts will never cease to amaze me.
