Efforts to require everyone in the car to wear a seat belt has hit another dead end in Arizona.

Rep. Bob Thorpe tried to convince the Committee on Health and Human Services to support his bill that would require back seats to also wear seat belts.

But, it lost Sen. Sylvia Allen's vote over the section that allows police to pull someone over because the driver, or anyone else, was not wearing a seat belt inside the vehicle.

"We already have a seat belt law. I think our law enforcement has a lot of things they need to be doing," Allen said. "And, I don't think trying to look over a window and see if everybody in the car has a seat belt is something that is going to be good use of their time."

Sen. Kate Brophy McGee cast the only vote in favor of the bill.

She compared its struggle for approval to her own efforts in trying to get a texting-while-driving ban passed, to encourage safer driving behavior.
