I guess i am qualified to post in this thread. On my third test i was pulling into the side and i clipped someones wheelie bin with my left wing mirror, that was the only thing i failed on too
Mounting the curb is a failure. Hitting the curb is a minor (steering or part of your manoeuvre). My friend hit the curb when driving along (steering minor) and my sister his the curb when parallel parking (minor on her parallel park).
