Tempe unanimously passed an ordinance banning smoking in cars while minors are present. The ordinance also applies to e-cigarettes.
Tempe Councilman David Schapira introduced the measure in January.
"It’s an acute problem in the Valley because so many of us drive, we drive long distances, we drive in high temperatures, and so we have our windows rolled up and the effects of second hand smoke on in that closed contained environment on a young person are very acute," Schapira said.
First time violators will face a $50 fine and $100 for subsequent offenses.
The ban goes into effect in 30 days.
