A Bay Shore woman was killed and her two passengers injured when her sport utility vehicle crossed out of the HOV lane on the Long Island Expressway in Hauppauge, striking another vehicle, Suffolk County police said.
Andrea Acosta, 22, was pronounced dead at the scene, police said.
A front-seat passenger, Casandra Carreon, 18, of Brentwood, was taken to Stony Brook University Hospital where she was being treated for serious injuries.
Another passenger, Francisco Ayaraca, 19, also of Brentwood, was taken to Stony Brook with injuries that police said were not life-threatening.
Acosta was driving a 2004 Chevrolet Trailblazer in the HOV lane of the eastbound LIE, approaching Exit 57 at about 4:10 p.m., when she crossed over the lane buffer and across an additional three lanes, police said.
She struck a 2013 Hyundai that was in the far right lane, police said.
Deputy Insp. Stan Grodski of the highway patrol unit said it appeared that Acosta was trying to get to the ramp.
"There are skid marks that go across all three lanes," Grodski said.
Gregorio Pisciotti, 50, of Patchogue, the driver of the Hyundai, was not injured.
The accident closed at least three lanes of the expressway for several hours of the afternoon rush hour as Fourth Squad detectives and crime scene officers gathered evidence. The LIE reopened about 7:30 p.m., police said.
Both vehicles were impounded for safety checks.
