An 11-year-old boy was expelled from school after crashing his family's minivan near a group of classmates, and his mother, who was in the vehicle with him, was ordered to appear in traffic court.

The crash happened just outside St. John Fisher School (search) on Chicago's South Side not far from where the children were lining up to go inside for class.

The minivan jumped the curb and hit a school zone sign as the boy tried to turn a corner, authorities said. No one was injured.

Sister Jean McGrath, principal of the Catholic elementary school, said the fifth-grader was expelled because "that's our policy if the child is a danger to himself or others."

Police said they don't know why Erin Sarandah (search) decided to let her son drive the 1998 Ford Windstar the couple of blocks from home to the school while she and her daughter were passengers.

"She had a license," said Police spokesman Pat Camden. He said there was nothing in the report that indicated any reason she might be unable to drive.

A telephone listing for Sarandah could not immediately be found Tuesday.

Sarandah was cited for damage to property and allowing an unauthorized person to drive, Camden said.

Her son, who won't be eligible for even a learner's permit for four more years, got a traffic ticket for negligent driving and driving without a license, Camden said. The boy's name was not released because of his age.

The two are scheduled to appear in traffic court on June 30.
