Two off-duty state police officers also rendered aid at the scene.
Haverhill firefighters extricated the teenagers from the vehicle.
They were both sent by ambulance to Lawrence General Hospital with serious injuries, state police said.
The driver was subsequently pronounced dead at the hospital. She was not identified Saturday pending family notification.
The passenger was sent to Tufts Medical Center for further treatment.
State police are investigating the cause of the crash.
