This quick-thinking bus driver may have accidentally revealed herself to be a guardian angel in disguise after she saved a student from almost certain disaster.

Samantha Call has been a bus driver for the Norwich City School District of New York for the last six years, and her training came in handy last month as she was driving along her usual morning route.

Security footage shows Call stopping the bus to let a young boy exit – but just before the boy is about to rush out the doors, Call grabs the hood of his jacket at the same moment a car can be seen whizzing past the bus.

If Call had not intervened as quickly as she did, the boy would have most likely been hit by the car.

"Samantha did an outstanding job," NCSD Transportation Supervisor William Loomis said. "All of our drivers undergo continuous training so they're prepared to handle situations like this. We hope this video helps everyone to realize the dangers of passing a stopped school bus."

Since the school district posted footage of the incident to Facebook, it has been viewed almost one million times – and school representatives hope that the video will help people to understand the importance of school bus safety regulation.
