A 17-year-old mother's swift action may have saved her baby from being crushed by an out-of-control car, video footage shows.

Alondra Gervacio was walking her daughter, Perla Galindo, in a stroller on the sidewalk Tuesday in the Bronx. A livery cab on the street suddenly careened toward them when the driver suffered a fatal heart attack, NBC News reported.

Watch the security video in the NBC segment above as Gervacio attempts to dart with the stroller away from the car. Despite her nimble attempt, she and her daughter are struck. Gervacio then scrambles to pull the baby out from under the wreck -- a move that witnesses said likely saved Perla's life.

"The mother took her out really fast," witness Trisha Torres told CBS.

After being admitted to Lincoln Hospital for what outlets described as minor injuries, the mother was discharged later Tuesday and the daughter on Wednesday, a hospital spokeswoman told The Huffington Post.

Dr. Rachel Rosansky, another witness, told ABC that the driver appeared unconscious well before he hit the pair and crashed into a Dunkin' Donuts storefront. The 68-year-old man was later pronounced dead at a hospital.
