All slip roads coming on, as above D & G sneaky gits.
As you approach J10, they can sit on the bridge about 1 mile from where you come into view and time you, slipping on behind you as you pass!
Bridge around Johnstone Bridge(sure its that) Services, before Moffat slip road, camera van on bridge.
Unmarked cars of various types, I'm sure someone will update these!
Why not stick to the limit?
