Does il semble require the subjunctive?
Il semble may require the subjunctive, depending on what the speaker means to say.
When expressing a fact, something that is obviously true, il semble que is followed by the indicative.
Il semble qu’elle veut conduire.

(She told me this and now I’m telling you.)
When expressing a doubt or possibility, il semble que is followed by the subjunctive:
Il semble qu’elle veuille conduire.
It seems like she might want to drive.
(I told her I was driving and she seemed disappointed.)
The subjunctive is also used after negative and interrogative statements.
Il ne semble pas qu’elle veuille conduire.
It doesn’t seem like she wants to drive.
Semble-t-il qu’elle veuille conduire ?

When expressing a possibility along with an opinion, you can use the conditional:
Il semble qu’elle pourrait conduire mieux que toi.
It seems like she might drive better than you.
