A woman was struck by a moving car after she stopped to grab a slice of pizza, witnesses said.

The unidentified woman in her 20s left Vinnie’s Pizzeria in Williamsburg at around 11:20 p.m. and attempted to hop into a mini-van that began to drive away, according to police and witnesses.

While she was desperately clinging to the door handle, the driver of the mini-van “gunned it” at Bedford Avenue and North 10th Street, witnesses said.

“The woman was trying to get into the van. She was clinging onto the sliding door,” said a 29-year-old motorist, who saw the chase from his rear-view mirror.

“She was literally running with van as it was moving. I saw her like fly off the car.”

The woman was taken to Bellevue Hospital where she was listed in serious condition.
