EACH DAY lorries pass seamlessly along the M74 and M6, the frontier that separates Scotland and England. The actual boundary line is the River Sark, which passes under the motorway.
For the trucks that stay on the motorway it’s as you were, but where things do change is when you head off the motorway onto the single carriageway roads.
Hop off the M6 at J45 and turn right, it takes you along the A6071 to Longtown to join the A7. Here, in any heavy goods vehicle, you can do 50mph because it is still England.
