WATCH: The Shocking Moment A Toddler Falls Out Of A Moving Car

A dashcam has captured the shocking moment a toddler tumbled from the back seat of a moving vehicle. 

Witness Chad Mock was driving behind the car in Mankato, Minnesota, when the toddler rolled out of the back door while strapped into a car seat.

He stopped his own car to run to the toddler's aid as the vehicle it was in kept driving.

"If it didn't happen in front of me, I'd never have believed it," Mock posted on Facebook, where he uploaded the video.

According to Mock, paramedics and police arrived to check on the toddler, who was uninjured. The parents later returned to the scene, Mock said.

"Very lucky," he wrote.

Police said while the child was properly strapped into the car seat, the seat itself was not fastened into the vehicle, according to local reports.

No charges have been laid.
