About this data Can these records approve an oversize or overweight route?+ No. Inventory data alone does not establish route clearance. Current restrictions, permits and route-specific engineering remain necessary.
Are load-rating fields legal truck-weight limits?+ They have their own source definitions and are retained as original attributes. Korzy does not convert them into a legal truck-weight authorization.
