A Port Jefferson Station woman was critically injured on Sunday night when her car crashed into several objects on the side of the road and landed upside down.

The Suffolk County Police Department said 21-year-old Tiffany Aldughmy was driving west on West Jericho Turnpike in Smithtown at 7:11 p.m. when she went off the roadway near Caleb Smith State Park. The 2000 Honda Accord hit a fire hydrant, a fence and a utility light, then overturned.

Aldughmy was listed in critical condition at Stony Brook University Hospital, police said, while a female passenger was treated at the same hospital for minor injuries.

Police impounded the Honda for a safety check and detectives from the 4th Squad are investigating.

Anyone with information about the single-car crash may call detectives at 631-854-8452.
