It is the level most often checked before a five-digit decision is finalized.
Selection note
How to choose it
Use this class to choose between its final subclasses such as Freight Terminal Facilities for Trucking Companies, Operation of Parking Lots, and Operation of Toll Roads and Bridges. If two options look close, compare the exact activity, the outputs and the way the business actually earns revenue.
