james croft:I have carried up to 18 cylinders in a pick-up truck and felt uneasy about it. I felt sure I was bending some DOT regulations. I also took the PSI Visual Inspector course and brought up this same issue as to regulations on transporting cylinders. The instructor advised that if I had 20 cylinders I would have to have placards on my vehicle. I cannot vouch for the accuracy of this statement, however. I do know I would not like to be in or anywhere near a vehicle with loose tanks in a rollover, wreck, or other situations that can occur on the highway. He did tell me to place the valves toward the front of the vehicle so if the valves were snapped off in a rear end collision the cylinder would not blast off towards the passengers.....
i heard it other way around...same as sb_diver
the valves will fly a lot further and harder than the tanks...
