Wild new video captures the moment a 16-year-old boy behind the wheel of a speeding BMW slammed into a parked UPS truck in Queens — sparking a chain-reaction crash that killed his 14-year-old passenger.

The footage, posted on the Citizen App, shows the red 2005 BMW 325i spinning out of control after it hit the truck and then ramming into the side of a tractor trailer — ejecting young Fortune Williams and leaving her dead on the roadway.

Police said the older teen had been driving “at a high rate of speed” on North Conduit Avenue near the 160th Street intersection in Springfield Gardens around 6:40 p.m. on Wednesday when he crashed.

The brief clip shows several vehicles passing down the residential block before the whizzing motorist veers into the right-center lane – but loses control and strikes the rear left side of a parked UPS truck.

The impact causes the truck to partially jump the curb, knocking down a UPS worker who had been trying to enter the passenger side, according to the footage. 

The BMW then spins clockwise across the roadway and back into the left-center lane — where it strikes the right side of the tractor-trailer, cops said. 

Responding officers found Williams lying in the street with severe head trauma. She could not be revived.

Additional videos posted on Citizen show the dilapidated BMW — torn nearly to bits — in the middle of the roadway as NYPD officers investigate.

The teen driver was taken to Cohen Children’s Hospital in stable condition with complaints of pain.

The tractor-trailer driver, a 49-year-old man, stayed on scene and was not hurt.

The man who had attempted to get in the UPS truck was taken to Jamaica Hospital Medical Center, where he was listed in stable condition.
