An Illinois lawmaker has introduced legislation that’d make it illegal to smoke in a car while a child is present. Chicago Democratic Senator Ira Silverstein is sponsoring the measure. He says it’s aimed at protecting children from secondhand smoke. Anyone who violates the measure would face a $100 fine, but police wouldn’t be able to pull over drivers simply for a smoking violation. The Springfield bureau of Lee Enterprises Newspapers reports six other states have a similar ban. Last year, lawmakers passed a resolution that encouraged people from driving and smoking with children in the car, but the measure didn’t ban the practice.
