Gov. Cuomo saved a struggling passenger from a van that tipped over on its side following an accident on the Brooklyn-Queens Expressway on Monday.

The man was trapped by his seat belt, and Cuomo freed him using a seat-belt cutter, an emergency escape tool that his State Police detail had on hand.

The governor and his staff were traveling east on the BQE when they came across the delivery van crunched against the divider in the westbound lane.

“They were the first on the scene,” a Cuomo staffer told The Post.

Cuomo had been coming from a luncheon for the Association for a Better New York at the Ziegfeld Ballroom in Midtown.

Video taken by Cuomo’s staff and later posted to Twitter shows the governor grabbing the man by his leg as he and others help him out of the driver’s side door.

The man appears to walk away from the vehicle unscathed.

Printed on the van’s door was the name “Regina Caterers” and an address for the business in Borough Park, Brooklyn.

EMS was notified of the accident and responded at 1:17 p.m., but there were no injuries, only damage to the vehicle, according to FDNY authorities.

When contacted by The Post, a spokeswoman for Regina Caterers confirmed that the van was a company vehicle but added that the company “had no details of what’s going on right now” and were “dealing with it.”

“Try calling back tomorrow, we don’t know anything right now,” she said.

Cuomo spokesman Rich Azzopardi couldn’t explain why a trained professional — like one of the governor’s State Police bodyguards — had not administered the rescue instead.

“He has on-the-job training as governor,” Azzopardi said.

Cuomo is fond of roadside assistance and has a history of lending a helping hand to motorists in distress.

Early last month, the governor was on his way back from a snowstorm briefing in Kingston, Ulster County, when he stopped on the New York State Thruway to help a couple involved a two-car crash in Selkirk, outside Albany.

There were no injuries in that crash, but Cuomo helped get the shaken couple to the nearest State Police/Thruway Authority barracks, his office said at the time.

In November, Cuomo helped emergency crews rescue a child during intense flooding in the upstate town of Dolgeville.

In January 2019, Cuomo, clad in khakis and jacket, trudged out into ice-cold temperatures in the Buffalo area and personally admonished truck drivers who were violating a state-imposed ban on large vehicles following a winter-storm state of emergency in Western New York.

“What are you doing?!” Cuomo scolds a driver in one video posted to Twitter.

“You know there’s a driving ban right?”
