A bill that would have barred adults in Tennessee from smoking in a vehicle with children appears dead for the year after lawmakers voiced concerns that it gave the government too much power over citizens’ freedoms. The measure failed to clear the Senate yesterday. The bill was sponsored by Knoxville Republican Senator Richard Briggs. It would have made it an offense to smoke in a vehicle with children under the age of 14, regardless of whether the windows in the car were rolled down. Briggs cited the dangers of smoke to children in a confined space as small as a vehicle. But some lawmakers questioned whether it was too much of an overreach. Sparta Republican Senator Paul Bailey said lawmakers couldn’t legislate the morality of Tennesseans.
