For an example, the trucs that tranport food and health care would be all checked. Also they will defenetly need to do lots of printing! That means rows of trafic up to 17 miles at the Port of Dover-thats a lot! There could be even more problems at Northen Ireland and Repblic of Ireland.There was a physical border with customes checked, but for may Ireland nationalists it was seen as a symbol for British occupation.They were all removed as part of the Northen Ireland peace proces.
After Brexit,there could be lots of problems that we will go through-it will be hard. But come on we need to get our head around it . It will be way easyer.
