BEAR, Delaware (WPVI) -- An idea created by elementary school students becomes law, and it may save lives.
Delaware Governor John Carney signed a bill Wednesday morning making it illegal to smoke in a car or truck while a minor is in the vehicle.

He was at Wilbur Elementary School in Bear with the 4th-graders who were behind the law.
The students went before the legislature to lobby for the bill as part of a civics lesson.
