The Democratic governor was reportedly leaving an event hosted by the Association for a Better New York when he spotted the wreckage and took action, according to local reporter Zack Fink, who shared the video reportedly taken by Cuomo's staff at the scene.
The footage shows Cuomo, still in his suit jacket, assisting EMS who had responded to a report of a crash. The video and a still image revealed that the driver's vehicle had turned over onto its side.
It is unclear if Cuomo witnessed the crash itself or was driving by and stopped when noticing the wreckage.
Fox News has reached out to Cuomo's office for comment.
The motorist's physical condition is unknown at this time.
Earlier in the day, Cuomo focused on public transportation, announcing a plan for expanding midtown Manhattan's Penn Station, which he called "the weak link in our region's transit system." The proposal calls for a larger facility and additional tracks to improve subway and train service.
