The National Code Of Practice For Light Vehicle Modification And Construction
The National Code Of Practice for Light Vehicle Modification and Construction (NCOP) is a draft standard that the Commonwealth is attempting to get the states to adopt so that there is a National set of Vehicle Modification Standards applicable accross all of the country. Some states are not too keen on giving up their rights in this area, so progress is slow. For some of us, that is a good thing.
But anyway, we don't want to get into a discussion about degradation of state powers here, we'll leave that to those with an interest in Constitutional law!
The latest public draft of the NCOP is available here.
