Police are investigating a wrong-way crash that happened in Mount Kisco early Friday morning.

They say it happened on Saw Mill River Parkway around 3:50 a.m. just before Croton Avenue.

County police say the driver was drunk and going southbound in the northbound lane.

The driver hit a Metro-North Railroad truck that had three people inside.

Those three people, and the driver of the car, were taken to Westchester Medical Center for minor injuries.

Police say the 29-year-old man from Bedford Hills is charged with driving while intoxicated.

This comes less than a week after a Connecticut woman was killed when she drove the wrong way on the Hutchinson River Parkway in Scarsdale. She crashed into two cars.

It is unclear why the woman was driving the wrong way.
