Also useful for Recreational Vehicle (aka "land yachts") - some
tunnels require small natural gas or propane (cooking gas) tanks be
turned OFF at the tank, some ban all tanks.

So this is a useful attribute for a road net database that is to be
used for routing.


(of course, we must be sure to source such data from appropriately
licensed source or actual signage, not from commercial hazmat atlas.)

OT - Only time in my long career that I've been paid to do GIS, I was
producing hazmat atlases of a different sort -- where was the hazmat
concentrated on the rail grid?
