Okay, so that no one thinks that I don’t understand anymore, allow me to paraphrase the previous posts.
Wide right turns are necessary because the right turn (i.e. into the nearest lane) is sharper. Left turns (the farther lane) does not have to be as sharp, and no wide turn is necessary.
ChiefScott may not have spelled it all out for everyone, but he said enough that I understood what he meant immediately. (That’s why I felt stupid. It’s obvious.)
Mr Trucker, thanks for the professional’s input. I see from your profile that this is so far your only post. Don’t be a stranger.
Carpe hoc!
