Sorry about that. From the article-Border guards and customs officers would check the electronic security tags of lorries and their holds at a £1.6 million facility being built in Kansas City, before sending them on to the road network that links the US cities of Chicago, Minneapolis and Detroit with Ottawa, Winnipeg and Vancouver across the Canadian border.
IMO- we would be trusting foreign nationals to ensure the loads are legal prior to their arrival at the Port of Entry in Kansas City.
The inland ports, including Kansas City, will be used to inspect cargo bound for Mexico.
