Really ?? Is there a government inspection VIP certificate threw the DOT ?? If there was then a certificate # should be required by the DOT labeled on each VIP sticker. Can anyone show us in print where the DOT requires an inspection every year with a government approved certification. If so where is the DOT cert # on all of the VIP stickers. Hydro’s are the only DOT requirement that I know of. And that is recorded and stamped on the tank. Not a peel off $0.50 sticker that anyone can have printed on adhesive peel away paper. Think about it
