The majority of the non-English speaking drivers are licensed in Canada and Mexico. So this doesn’t address that issue.
The other issue is that if you actually removed all the non-English speakers from the road, you’re talking like… half of all the CDL drivers? Maybe over half. You can’t suddenly replace that group with English speakers overnight, it would take many years.
Instead, seems like the system should be to trying to teach the existing drivers English? Is that somehow harder?
Meanwhile, in the civilized world, we use universal road signs:
https://en.wikipedia.org/wiki/Vienna_Convention_on_Road_Signs_and_Signals
Is it universal? The list has tqk or three different designs for each thing, often quite different like the stop sign options.
I tried to find the wiki page showing a comparison of all the nations versions of the roadsigns, there are slight variations sure, but the general designs are defined here:

Haha I seem to get rate limited on images trying to load some of those pages, after the first 30 or so it just stops working.
This most interesting one to me was the stop sign, which, from your first link, could be:
Or it could be:
However, from your priority signs link, it seems nowhere in Europe actually uses the second one.
Wait who’s serving whom here?
