A Yonkers man pleaded guilty Monday to the wrong-way crash death of an NYPD detective in February 2015.
Efren Moreano, 21, pleaded guilty to vehicular manslaughter.
Prosecutors say Moreano drove into the Sprain Brook Parkway in Greenburgh through the Jackson Avenue exit and drove around two miles in the wrong direction.
He crashed head-on into the car driven by Detective Paul Duncan, who lived in Hartsdale and was on his way to work in Queens.
Investigators say Moreano was traveling around 105 mph and had alcohol and marijuana in his system.
He will be sentenced in June.
