The vehicle crashed into the back of a home on Kory Drive in the Kendall Park section just after 9 a.m.
Police say the mother was dropping her child off at school when she suffered some sort of medical emergency that caused her to drive through the parking lot, over a field and into the back of the home.
The mother and the third-grader, who was in the back seat, were both injured. The extent of their injuries is not yet known.
The accident led to a gas leak. Several surrounding homes were evacuated before PSE&G was able to shut the gas off.
The school was placed on a shelter in place for about 20 minutes.
Officials have determined the home that the car crashed into is uninhabitable due to the extensive damage.
Brunswick Acres Elementary School is operating as normal, officials said.
