Several people were struck by a vehicle in Chelsea on Monday afternoon, the NYPD said.

The accident just before 4 p.m. on West 29th Street and Eighth Avenue sent 10 people to the hospital, including a woman who witnesses said was hurt but alert.

Video shows a Ryder box truck strike a parked and unoccupied white van, sending it onto the sidewalk. Police said the box truck was traveling northbound on Eighth when the driver lost control. The FDNY said the victims were transported to Bellevue Hospital, with at least one listed in critical condition.

The driver and the passenger of the box truck remained at the scene and were being questioned. Police said the crash did not appear to be intentional, but it's unknown at this time if charges will be filed.

Witnesses describe a chaotic scene

Moments after the crash, good Samaritans rushed in to help as those nearby counted their blessings.

"I'm grateful that everybody is alive and I'm alive because that is kind of a relief. I mean, because it literally happened right in front of me," a witness said.

"We just heard a loud bang and we saw one vehicle hit a woman, hit her into the wall. And this truck came flying out behind them," said Sydney Ellenson, a tourist from Minnesota. "Evidently, they weren't paying attention, is all you can think of. Thank God it was that they weren't going any faster."

"We saw everybody pause for a moment. We saw cars getting pulled over," Kelvin Rodriguez added.

Police said one lane of Eighth Avenue was later opened to traffic, but advised people to avoid the area for the time being.
