Police say a drunken driver is to blame for a crash involving a taxi minivan and an SUV in Southampton early Monday morning.

Authorities say the taxi driver picked up four people at the Pink Elephant Club on County Road 39 around 4:15. They say the driver of the cab attempted to make a left-hand turn into a 7-Eleven parking lot, when the other vehicle crashed into the cab. The crash happened at North Sea Road and Route 27.

Police say all four of the taxi?s passengers were ejected from the minivan. Two are listed in critical condition at Stony Brook University Hospital. The other two are in stable condition at Southampton Hospital. The drivers of the cab and SUV only suffered minor injuries.

Police say the driver of the SUV, 18-year-old Ryan Rozynski from Shirley, was charged with drunken driving and is expected to face more charges. The taxicab driver faces a summons for crossing a double yellow line.

Southampton residents and police say there used to be ?Do Not Enter? signs on the side of the 7-Eleven driveway, but they were knocked down in a crash a few years ago. The county tells News 12 Long Island the signs will be replaced.
