Ok challenge accepted:
ďI think some states may have laws against it while under wayĒ
Was directed at tunnels. Not necessarily related to general travel, but I guess that wasnít clear as I wrote it.
Sue me for unclear communication - lol
I should probably proof read more often.
I donít think there are laws against valves being open in general while traveling - none that I can confirm other than on certain roads or specific areas like ferries, tunnels, etc.
But a challenge is a challenge
This site states itís illegal to travel with propane on. No real detail on specifically if just in tunnels or on highway, it just says ďillegal to travel with valves openĒ so take it for whatever thatís worth.
Scroll to bottom of article:
Also A couple of states specifically listed as no propane in certain tunnels valves or no valves.
Just no propane in those tunnels period.
See Maryland and New York:
Other states like Texas say propane ok if valves closed in certain tunnels.
Personally I have always driven with my propane fridge on and running.
Just 2 weeks ago I drove through the Mobile Tunnel on I-10, and yes I forgot to stop and close valves, fortunately no one caught me doing that.
But then maybe itís ok in Alabama?
Do I condone this practice - NO
But I do make fun of it because I am a realist and I know most of the other RVs traveling donít close theirs either.
Same goes for gas stations:
People just gas up even with a propane fridge burning a few feet away.
That one worries me some, itís a risk few even realize.
