A beloved Westchester County teacher lost her life while trying to cross the street in New York City.

Sarah Foster, 27, was killed when she was hit by an oil truck in the crosswalk at the intersection at East 37th Street and Third Avenue around 6 a.m. Saturday.

“He didn’t even see her, “ Mike Simmons told the Daily News. "Her body was behind the truck and he had definitely run her over. She was in his blind spot when he made the turn. She was so young. It was tough to see that."

The driver remained at the scene and was charged with failure to yield to a pedestrian and failure to exercise due care.

Foster recently moved to an apartment near where she was fatally hit, neighbors told the New York Post.

Foster was a sixth-grade social studies teacher at Louis M. Klein Middle School in the Harrison School District. She also coached girls volleyball.

"Sarah was an extraordinarily warm, talented and dedicated young teacher. During her time in Harrison, her contributions as a teacher, colleague, and coach were far-reaching. It will be Sarah’s enthusiasm and joy for learning and for life, evident in all that she did, that will remain with all of those she touched," Harrison Superintendent of Schools Louis N. Wool said in a statement.
