Gov. Bruce Rauner has signed legislation allowing immunity from prosecution to minors who call 911 to get help.
The bill provides legal protection for a person needing medical help and the person who called for him or her.
Police would have the authority to determine whether protection from legal discipline is appropriate.
The plan is modeled after a similar one addressing heroin overdoses. At least two dozen other states have similar laws.
The Illinois law takes effect Jan. 1, 2016.
