(CNN) A school bus driver was arrested after she overdosed while driving and crashed into a tree, Newark police said.

The driver, Lisa Byrd, was transporting a dozen students from 14th Avenue School in Newark when the vehicle crashed into a tree on Wednesday, officials said in a statement.

When first responders arrived, police said they revived the 57-year-old woman with Narcan -- a drug that instantly reverses the effects of overdose from heroin and other opioids.

The students, ages 5 to 13, were not injured, police said.

Byrd, who was taken to a local hospital, is facing 12 charges of endangering the welfare of a child, driving while impaired and possession of drug paraphernalia, police said.
