SAN-supported legislation to expand the permissible use of cars equipped with nitrous-oxide systems was signed into law by Maine Governor John Baldacci. In 2003, working with the Maine Custom Auto Association, SEMA Action Network (SAN) amended a Maine bill that originally threatened to prohibit the operation of vehicles equipped with nitrous oxide or other “power booster systems” (e.g. superchargers) on public roads. Under the amendment, the bill permitted vehicles equipped with nitrous-oxide systems if all canisters of nitrous have been removed or if the vehicle is en route to or from a racetrack. The new law also allows the public highway use of vehicles equipped with nitrous systems if they are en route to a car show, off-highway competition or fill station.
