A Nebraska substitute teacher was caught naked in a car with a teen student — who tried to flee but crashed and ran from the scene in his underwear, cops said.

Erin Ward, 45, was scooped up Saturday night after she was found in the buff with a 17-year-old male student from the Omaha high school where she taught, according to the Douglas County Sheriff’s department.

Police caught up with the married sub after receiving a call about a suspicious car parked down a dead end around at about 3 a.m. that night.
