Van is out of control on Fifth Avenue

An out-of-control — and possibly drunk — driver smashed into a Fifth Avenue bar in Park Slope on Sunday evening, shattering the storefront window, injuring himself and a cab driver.

The driver of a green Pontiac van — who was “very drunk,” according to one witness — collided with a yellow cab before plowing into Cypress Avenue bar at Bergen Street just before 5 pm.

The van was speeding eastbound on Bergen Street before it slammed into the cab, which was heading northbound on Fifth Avenue, according to witnesses.

Ambulances arrived within three minutes and medical workers treated both drivers.

On Monday, the bar’s outside patio was shuttered — but the word “open” had been scrawled in large chalk letters on the side of the building. A cop at the 78th Precinct said he had “no information” about the crash, and the owner of Cypress Avenue did not immediately return calls seeking comment.
