well i always wear mine on or off road. in a jeep, the doors and top are not gesigned to contain you in a crash or rollover situation. i would not risk my life that way. i was on my way home from the dirt track one sat night and i saw a car off the side of the road so i stopped to see if i could help. well, a guy in a saturn hit an enbankment head on.he and the passenger were wearing their seatbelts and the airbags deployed. she died on impact and the driver (her boyfriend) got his leg broken very badly. she had two kids that were less than 6 years old.
Needless to say i didnt sleep that night but i did learn something from that. if someone can be killed in an airbag equipped car while wearing their seatbelt the YOU dont stand a fighting chance in a Jeep or any other vehicle without a seatbelt. they might not be the most comfortable thing in the world but when something disatrous happens, it will help save your life.
I NEVER even leave the driveway without my seatbelt on if i am in the jeep. there are too many IDIOTs on the road with their cell phone glued to their ear and their radio Blasting some "BUMP" and not paying attention.
Be safe and have fun...That is what jeeping is about
