を or で should be applied?

あの　信号を　右へ　曲がってください。

Why not あの　信号で　右へ　曲がってください。?

I think the action 曲がる takes place at the 信号 (traffic light stand) and therefore で would be applied in this situation instead of を. I don't understand why を is used in this situation although it is right there in my Japanese coursebook (Lession 14 - Kaiwa - Minna no Nihongo).

Thank you for your help.

駅を降りる 駅を降りたら、どこからともなくおいしそうないい匂いがしてきた。 Why 駅を降りる？Does it mean "get off the station"? How can we get off the station. I think バスを降りる is better. Can you guys please advise if my understanding is correct?

日本語スキル：N1であれば尚良し I am applying for a Japanese company. However, my Japanese is not good enough (just around N3, I think). The company's requirement for Japanese is: 日本語スキル：N1であれば尚良し. Does it mean "if you have N1 (the highest Japanese certificate in Vietnam), it is a plus for you" or "You must have N1 or other higher certificate". Please help me. Thank you you guys in advance.
