By MyFM's Rick Michaels - State Representative Brian Murray of Milford a member of the Transportation Committee had never heard of “Rolling Coal” until a constituent reached out to him and he’s filing legislation to ban the practice. During a Transportation Committee hearing yesterday Representative Murray says a bill he’s filed will ban so-called “Rolling Coal” in which diesel truck engines are modified, to consume more fuel than needed resulting in thick, black smoke coming out of the tailpipe. Murray says the additional fuel doesn’t serve a useful purpose and the smoke is harmful. The bill would ban modifications to diesel vehicles, that enhances a vehicle to emit soot or smoke with violations punishable by a fine ranging from $100-to-$1000 dollars. Murray’s legislation co-sponsored by State Representative Carolyn Dykema of Holliston would make Massachusetts the third state in the country, outlawing “Rolling Coal”.
