A Hampton Bays woman was seriously injured in a crash in Centereach Tuesday morning, Suffolk police said.
Mireya Siguenzazhinin, 21, was driving a 2007 Subaru northbound on Nicolls Road, when her vehicle crossed over the center median, police said, and struck the rear of a southbound 2015 trailer, driven by Alex Lopez, 35, of Brentwood.
A bystander helped Siguenzazhinin before first responders arrived and she was taken to Stony Brook University Hospital. Lopez was not injured.
Nicolls Road, which was closed while police investigated, has since been reopened.
The Subaru was impounded for a safety check. Detectives are asking anyone with information on the crash to contact the Sixth Squad at 631-854-8652.
