As most cars swerved to avoid him, Jayson Tyree, 27, was driving a 2001 Volvo against traffic on the eastbound lanes of Route 109, west of Wellwood Avenue, about 2:50 a.m., when it collided with a 2012 Nissan near 1144 Rte. 109, police said.
Tyree was arrested and charged with driving while intoxicated and second-degree reckless endangerment.
At his arraignment Sunday at First District Court in Central Islip, Tyree was ordered held on $100,025 bond or $50,025 cash bail. He is scheduled back in court on Monday.
