Authorities say a majority of drivers in wrong-way crashes are impaired by either drugs or alcohol.
In July 2009, Diane Schuler was drunk and high when she got on the Taconic State Parkway heading the wrong way. Her minivan carrying her 2-year-old daughter and three young nieces struck a vehicle carrying three Yonkers men head-on. No one survived that crash.
A 2015 crash killed NYPD Detective Paul Duncan, of Hartsdale. His car was hit by a wrong-way driver who was drunk on the Sprain Brook Parkway. Eren Moreano, of Yonkers, is currently in prison for manslaughter.
Just last August, a woman was heading the wrong way on the Hutchinson River Parkway. She died and others were injured.
There have been efforts over the years to install better signage along ramps to some parkways.
