I recommend that you freely, of your own will, notwithstanding any law, choose to use your seatbelt every single time you drive. It is my personal experience that when you need it, it will turn sure death into a rear-ender walkaway you laugh at later over a beer.
Look at it this way - a wise person once pointed out, "If you want peace, prepare for war."
stick it up your ass. I regularly ride a motorcycle. If its so unsafe to not wear a seatbelt in a truck, then why are motorcycles legal? so you go parrot your stupid seatbelt crusade somewhere else.
