A 19-year-old woman was killed when a driver lost control of his car and jumped a curb, plowing into her as she waited for a bus at a city beach Saturday — and he’s in custody, cops said.

The woman, whose identity wasn’t released, was waiting for the bus at Beach 108th Street and Rockaway Beach Boulevard around 2:30 p.m. when she was struck by the compact car. 

She was rushed to Brookdale Hospital but couldn’t be saved, police said.

The 29-year-old driver was taken into custody with charges pending, cops said.

His name wasn’t immediately released.

It wasn’t immediately clear why he jumped the curb, police said.
