Seat belt laws have absolutely nothing to do with safety. They exist to generate more revenue to the state government through fines. That is their only reason for existence and politicians fool people, like many of you, into accepting these laws by making you believe they actually give a shit about your safety.
What is the fine for not wearing a seat belt in your state and or municipality? From my experience, they are low, and another question, are they a primary or secondary offense. In other words, some states do not permit an officer to pull you over simply for that, there must be another infraction/crime first to be a legal stop.
