A private garbage truck rammed into a car in East Harlem Tuesday, sending both vehicles careening into scaffolding that collapsed on a woman, gruesomely killing her, police and witnesses said.

The truck collided with an unattended parked Kia Forte at the corner of East 101st Street and First Avenue just before 6:30 a.m., with the impact forcing the Kia onto the sidewalk, cops said.

Surveillance footage captured the truck tearing down the wet and dark street, hitting several vehicles as it swerved out of control, eventually ramming into the white Kia, which wedged to its side.

Both vehicles eventually careened off the road and out of the frame, right into the scaffolding where the 60-year-old victim was walking, video shows.

The sidewalk shed in front of 345 East 101st Street then crumpled and fell on top of the woman, who was standing underneath — leaving her with grisly, fatal injuries.

“I saw them pull her out. Her legs were cut off like right here, by the foot,” a worker at a nearby deli told The Post.

“I saw the garbage truck coming really fast down First Avenue. It hit this car and then this car, and it dragged that car over there,” the worker said.

The victim was a regular customer at the deli, and collected cans for extra cash, he said.

She was declared dead at the scene, and was not immediately publicly identified. 

The garbage truck driver, a 47-year-old man, and a passenger, a 50-year-old man, were both taken to a local hospital in stable condition.

Witnesses said the truck was going so fast that it rattled nearby windows.

“He never stopped. He hit us and kept going,” said Will Bivens, 47, the driver of a white BMW SUV that was also hit by the trash truck before it wrecked the sedan.

“We never saw it coming,” Bivens told The Post. “He pinned us into the truck and then he kept going. He dragged another vehicle that he dragged into the scaffolding.

“I’ve never seen anything like that before.”

Wanda, a doorwoman who works nearby and saw the truck go by, said she could even feel her building “vibrating.”

“That’s how you can tell how fast he was going. He vibrated the building,” she said.

The truck belongs to a private waste management company, Classic Recycling, based in Clifton, New Jersey.

A spokesman insisted that the truck driver appeared to be going under the speed limit, and also said that he had tested negative for drugs or alcohol at the scene.

“We are still gathering information about this tragic accident and are not able to provide any details at this time,” the rep told The Post.

The truck’s driver has been with the company for two years with a clean driving record, according to Classic Recycling.

Wanda, who declined to give her last name, had just said hi to the victim when tragedy struck.

“Every morning, she knocked on my glass to tell me good morning,” she recalled. “She knocked on my glass at like 6:15 to tell me good morning.”

The NYPD’s Highway District Collision Investigation Squad was probing the cause of the crash.

A Classic Recycling truck was previously involved in a 2019 fatal pedestrian collision in Hell’s Kitchen, with the driver being arrested after the 4:40 a.m. for failing to yield to a pedestrian in a crosswalk.

The collapsed shed has been on the building — a New York City Housing Authority apartment complex — since 2023, and is permitted through 2026, according to the Department of Buildings.

About 80 feet of the shed was damaged in the accident, and DOB inspectors were on the scene after the accident. Work to repair it has already begun, the DOB said.
