Hartford (AP) — Connecticut lawmakers are again considering a bill that would prevent people from smoking in a motor vehicle when there's a young child inside.

Under this year's bill, someone could not smoke if the child is six years old or younger, or weighs less than 60 pounds. First-time offenders would receive a warning, while repeat violators could face an infraction.

Proponents contend the legislation is needed to protect children with developing lungs from the ill effects of second-hand smoke. Bonnie Smith, executive director of an East Hartford-based substance abuse prevention program, said in testimony that no one should be allowed to expose children to second-hand smoke in such a confined place.

The Public Health Committee is scheduled to hold a public hearing Wednesday on the bill, which failed in previous sessions.
