Agreed!
I thought this would be easy.. All the pictures I have found online do not show any of the small sticker positions.
Rule 8 may need to apply here, unless we have someone on the forum who has pictures which show prototypical positions.
My guess would be the larger 'no boots (skates, or snow-grips?) stickers on the doors of the power-cars.. The small ones like we would have no smoking decals on windows. the little warning triangles (I think) go over the doors so people do not poke skis into the overhead. The blue 'max xxx' and the rectangular I have no idea..
So, all in all, not a lot of help I am afraid!
