The bill would allow law enforcement officers to stop a vehicle if front-seat passengers seat aren't wearing seat belts.
By a 65-55 vote Friday, the bill remains in negotiations between House and Senate members.
The issue could return when legislators come back in late April after their recess.
It's a traffic infraction in Kansas now for a person not to buckle up. But officers can't stop a vehicle unless they have another reason.
The bill requires all passengers to wear a seat belt. However, officers couldn't issue a citation to passengers in the back seat for not wearing safety belts, unless another citation were being issued.
The penalty would be a $60 fine.
