Topeka ? The Kansas Senate gives first-round approval to a bill that would toughen state laws on using seat belts.

On a voice vote Thursday, the Senate endorsed a proposal requiring all passengers in motor vehicles to wear seat belts. Currently, only front-seat passengers age 18 or older are required to buckle up.

The measure would also let law enforcement officers stop and ticket motorists for failing to wear seat belts. Under current law, an officer must first stop a vehicle for another reason, such as speeding, and may then issue a citation for not wearing seat belt along with the other offense.
