The bill would prohibit motorists from smoking any form of tobacco in a car if they are transporting children in car seats or booster seats.

Genga cited a study by the Harvard School of Public Health that found unsafe levels of smoke even in cars with the windows open.
Rep. Prasad Srinivasan, the ranking Republican on the public health panel, also praised the bill but said it did not go far enough. "Restricting it to children who are in car seats is a good start, but I think second-hand smoke should be avoided in children, period. This is a bill that needs to move forward and include other ages, as well," said Srinivasan, who is also a physician.
