Perhaps you guys in Florida need to be as vocal as in KS. They tried to make it a primary offense two or three years ago, but the folks in Topeka backed off when they got quite a few angry phone calls from the people back home.
I almost always wear my seatbelt, but about a month ago, while running several errands and getting in and out of the car, I forgot to put it on. Trooper stopped me just for not wearing it. Cost me $140!! This is in Texas of all places. It's to make money and nothing else.
