An Act relative to rolling stock

This bill defines "rolling stock" as trucks, tractors, and trailers used by common carriers for interstate goods transportation. It adds new tax provisions for the sales, storage, and use of these commercial vehicles under Massachusetts revenue laws. The bill directly affects businesses that operate interstate trucking fleets, such as freight carriers and logistics companies. These changes modify existing tax code sections to specifically include rolling stock in retail sales and storage definitions, without altering tax rates or creating new fees.
