No matter what you're riding on/in... ALWAYS buckle up, ALWAYS wear your helmet, ALWAYS wear your PFD, etc. Why would you want to take the chance of killing yourself/others!? Whenever I have passengers, I make them buckle up b4 we leave - even if they don't wear a seatbelt when they drive their own vehicles. I'd rather have some injuries from wearing my seatbelt if I ever was involved in an accident (even major), than to die from NOT wearing my seatbelt, and going thru the windshield, and dying from severe internal injuries.
