I'm seeing stuff over Twitter suggesting drivers are refusing to return to the UK. Meanwhile major logistics firms are dumping the country entirely:

German logistics firm DB Schenker stops UK shipments over Brexit red tape:

German logistics company DB Schenker is temporarily suspending deliveries from the European Union to Britain because of bureaucratic hurdles brought on by Brexit.

The transport giant is experiencing "considerable problems" in customs formalities in the movement of goods between the UK and EU, it said in a statement sent to AFP on Friday.

Only "around 10 percent" of deliveries are accompanied by the complete and correct paperwork, it added.
