The plan, Senate Bill 2659, would impose an up-to $100 fine for any motorist who smokes tobacco, marijuana or any other combustible substance in a car with a person under the age of 18.
State Sen, Ira Silverstein (D–Chicago), the plan’s sponsor, testified before the committee's vote.
“There are very serious health effects associated with exposure to second-hand smoke, especially for minors," said Silverstein. "This plan is aimed at reducing that exposure."
Senate Public Health Committee approved the bill by a 5-2 vote. It next heads to the full Senate.
Police would not be able to curb drivers based solely on the offense, and the fine would not apply to motorcycles or convertibles with the tops dropped.
