Is a masters degree ok? Why or why not?

You're missing the point of the game.

It isn't simple.

> You pretty much have to assume intent, though?

That's the crux of the issue.

And the game calls this out at the very beginning. It encourages you not to speculate on if it should apply, just if it does apply.

The OPs assertion that this was easy missed the point.

> and obviously police and ambulances (and fire trucks) doing their jobs don't have to follow the sign.

I don't believe it was obvious, and it wasn't stated goal. These are vehicles. The rule applies to them.

The fact that we disagree is the entire point of this game.
