The accident happened at 7:13 a.m. Thursday in front of George Reed Middle School in the 300 block of East Basin Road in New Castle.
A Delaware State Police spokesperson says the girl ran out into the southbound lane and into the path of a 2008 Toyota Rav4.
The girl was taken to A.I. duPont Hospital where she was treated for an injury to her arm. A Colonial School District spokesperson said the girl is in stable condition.
The driver of the Toyota was not cited by police since the girl was not crossing at a crosswalk.
