[K.S.H]

I'm with you on the red one, seen people on the black one and they've gone right round and up Milnshaw lane!
I was taught, unless road markings state otherwise, if your coming off the first exit get in the left lane, for any other exit get in right lane and move to the left once you have past the junction before the one you want to exit from.
But if theres no road markings there they aint doing anything illegal, you can use both
One that really annoys me is the M60/M66 junction, its all colour coded and they still get in the wrong lane
