A small pickup crashed into the Lake Oswego Post Office just before 10 a.m. Monday.
The driver was pulling in to a parking spot and did not stop. A mail carrier, who was sorting mail on the other side of the wall, was slightly injured, according to the Lake Oswego Fire Department, and was taken to an emergency room.
The damage did not compromise the building's structure.
Lake Oswego Fire Department officials say they have not determined why the pickup did not stop.
