We were told that you need to have DOT approved metal gas cans. The only ones we can find that are "DOT approved" are 5 gallon for $180.00. I have seen the metal Type 2 cans and thought these were good enough. I am in New York and apparently in my area there is a local cop who LOVES to harrass the landscapers in the area by pulling them over and writing LOTS of tickets. His favorite is the gas can one which is $500.00 fine. Does anyone know anything about these cans or heard of anything? Thanks.
