Dash cam from Sergeant Anthony Mannino's patrol vehicle shows him plucking a toddler from harm's way in Naperville, Illinois last month.
"I was praying to God he wouldn't make a left turn to enter that lane of traffic", Mannino said.
Mannino was presented his department's lifesaving award on Thursday, the department said. He then chased the boy down, even as the 1-year-old continued running.
Dashcam captured the May incident and shows the officer running after the boy before pulling him to safety.

At one point, a large truck can be seen passing within a few feet of the child at a high rate of speed.
"I did what any of my peers would have done", Mannino said, "position that vehicle, get out and quickly corral that kid before something bad would have happened". Mannino then tells dispatchers he would begin looking for the boy's parents.
The department's post says the child "escaped his mother's watchful eye" and wandered along Route 59 as traffic whizzed by.
Sergeant Mannino with the Naperville police department saw the boy and sprung into action.
