Starting in the west, the M18 starts out by continuing from M1 near Sheffield. At the junction with A1 to the east, the M18 becomes M180, which continues for about 20 miles before meeting the A15. After that, the A180 road takes over, eventually ending at Grimsby.
- In UK Truck Simulator, the A180 was built as a circular road outside Grimsby, but it's converted to a straight road (as in real-life) in Euro Truck Simulator 2.
- In real-life, the M18 motorway branches off from the M1 and continues to M62 west of Hull, while the M180 motorway also branches off from the M18. Instead, both the M18 and M180 motorways continue from their "parent" roads in the games, meaning truckers starting from Grimsby and not turning off at junctions will eventually end up on the M25 near London.
