The girl was 15 when her SUV crashed into a car driven by Margaret Catyb's son in June.
Catyb of Dracut, Mass., died at a hospital.
On Thursday, Santa Rosa County Judge Robert Hilliard sentenced the teen driver to six months probation, ordered her to speak about the crash at her high school and revoked her driving privileges for a year.
Prosecutors tell the Pensacola News Journal that Catyb's family asked the court not to sentence the teen to jail because of her age.
The teen's mother was sentenced to 60 days in jail and six months probation.
