According to police, 32-year-old Ahmad Ladson was in the street performing his duties on Colgate Avenue in the Soundview section around 8 a.m.
Investigators say a Toyota Highlander hit him.
Ladson was taken to Jacobi Medical Center in critical condition.
A camera on a building across the street recorded the crash.
"Sanitation Workers have a dangerous job, as the horrifying video of this collision shows. Sanitation Worker Ladson remains at Jacobi Hospital receiving round-the-clock care, and every single one of New York's Strongest is incredibly grateful to the medical team there. Our entire Department stands with Sanitation Worker Ladson's family in this difficult time," the New York City Department of Sanitation said in a statement.
A fundraiser has already raised more than $40,000 for the father of three.
His family said they were thankful for the prayers and support and that they feel blessed he is alive and pray he will recuperate.
The 40-year-old woman who was driving the Toyota stayed at the scene.
Police say there are no arrests and the investigation remains ongoing.
