The "Clear all Signs" button on the Global Ops of the Traffic Interface NEEDS a confirmation box

If you click twice in Traffic mode, you get the signs screen. It's easy to accidentally click 3 times, having the third click hit the interface. If your mouse happens to be over the Clear all Signs button, you lose them all without any confirmation.

You could even just misclick that. I always have hundreds of custom signs on a map. I just accidentally clicked it after spending about an hour on a turn. There's no way I'm going to redo all my signs, so I now have to redo the entire turn from a previous save.

Any action that can cause that much damage without any way to undo it needs a confirmation dialog box.

Okay. I think your issue is that you think you need "hundreds of custom signs on your map".
Why would you think that?
How about trying not to need them?

While I am not opposed to more checks, I think the Traffic Sign Menu should be on the way out now that pull-points are a thing.

There are lots of situations where you might want to keep those roads that are not needed for logistics right now :
- for faster operational movement while wanting to block logistic movement through them
- to minimize branching
- to keep those expensive mountain paths that you might need in the future
- to deal with newly conquered roads
- being so strapped for IPs than even demolishing roads to clean them up doesn't sound appealing
