A city sanitation worker’s legs were crushed, leaving him critically hurt, when an SUV driver rammed into him, pinning him against his garbage truck in a caught-on-video Bronx crash, officials said Tuesday.

Ahmad Ladson, 32, was picking up trash on rain-swept Colgate Ave. near Watson Ave. in Soundview when a 40-year-old woman driving a Toyota Highlander rammed into him about 8 a.m. Monday, cops said.

Ladson was pinned against the edge of the sanitation truck’s hopper.

Surveillance video shows Ladson facing his truck with his back turned to the SUV as it careens into him.

After being pinned between the two vehicles, Ladson, who was wearing a yellow reflective jumpsuit, falls to the ground and rolls into the middle of the street, screaming in agony.

Medics took Ladson and the driver to Jacobi Medical Center, where the city trash hauler remained in critical condition Tuesday.
