Two cars left the roadway and ended up in the water in separate incidents Sunday morning, police said.
Alejandra Moya, 24, of Westhampton Beach, was driving a 2009 Honda on Broadwaters Road in Cutchogue at 8:25 a.m. when she lost control on an icy patch of road and slid into Broadwaters Creek, Southold Town police said.
Moya's vehicle overturned and became partly submerged, police said, but she was able to get out and go to a nearby residence for help.
She was not injured, and the Honda was retrieved from the water, police said.
About half an hour later, in East Rockaway, a 24-year-old Nassau man suffered a seizure and lost control of the 2005 Cadillac he was driving, causing it to go off a dock at Althouse Avenue and Dock Street, Nassau County police said.
That driver, who was not identified, got out of the car and made it out of the water on his own, police said.
He was taken to a hospital to be evaluated and treated for minor injuries, police said. The police department's Marine Bureau and Emergency Service Unit removed the car from the water, police said.
