It is the law in Georgia (well I think it is the law in every state actually) that the driver and all passengers under the age of 18 must wear a seat belt while the vehicle is in motion. In addition, all passengers in the front seat (regardless of age) must wear a seat belt.
That is of course, unless you drive a pickup truck. In Georgia, at least, if you are driving a pick up truck you are exempt from wearing a seat belt. The legislature decided not to include pickup trucks because of a fear that the law would inconvenience farmers. Georgia is the only state in the nation that continues to exempt safety belt use in pickup trucks.
I think the Click It or Ticket poster is quite interesting - I mean how is this guy in the poster suppose to even put on his seat belt since his is obviously arm-less? Poor little arm-less guy with the teeny tiny legs. I seriously hope this dude is not in an accident. Even though he is buckled in, I'm sure the impact of the crash will cause his head to go flying through the air - considering he also has no neck to speak of.
