Runway signs show the ILS category next to the runway designation. But if you flew and didn't drive to the airport, you already know (hopefully). Either way, you are taking off, so you don't really much care. One might say that you will have to land again in case of emergency, but ATC might not give you the same runway. So what's the reason of showing ILS category on runway signs?
Note: I changed "markings" to "signs" in this question since markings are painted on the ground, signs are the red ones I am asking for.
EDIT: The linked question is not exactly the same:
What is the purpose of several mandatory stops (RWY AHEAD) at busy airports?
What are mandatory stops? How are they several? (I never noticed that). I didn't know all these until I asked about the "runway signs". The other question presumes that you are familiar with some terminology. And it doesn't mention ILS.
Also, it looks like a similar case. I vote for reopening.
