Maryland senators will continue debating a bill to outlaw smoking in a vehicle with a passenger younger than 8. Lawmakers amended the bill by changing the age at which a child cannot be exposed to smoking in a car to 16. However, after supporters of the bill appeared to realize they had voted in error, the amendment was overturned. Proponents said that while second-hand smoke is harmful to children of all ages, limiting the ban to children under 8 will make the law easier to enforce. They said police officers will know a child under 8 is in the car because until that age children are required to ride in car seats.
