Interesting that a lot of US road signs have words on them: https://ygraph.com/graphs/roadsigns-20120316T030941-ekrruua.... , or are obvious, whereas in Europe drivers need to learn what they mean: https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh...
For example the yield triangle, no stopping and no parking are probably unfamiliar to US drivers.
Meanwhile all Alfa Romeo Quadrofoglio drivers might be mistaken for drivers with missing limbs in Japan.
It did also make me a bit worried about the expected level of driver education...
Not just driver, but of the general population. A few decades ago, the general reading level was at the 6th grade (thanks to the policies of Ronald Regan) and republicans think that is too high and have been working intensely to lower it. Won't be surprised if it's dropped given the "golden" opportunity of covid. I know it's only been a few years (centuries for most Americans) since Betsy DeVos was secretary of education. Remember that era?
American signs very frequently combine both styles - for instance, you see the above words next to a sign with arrows for whatever lanes, wordlessly illustrating the turn types permitted.
If someone is a new driver, who hasn't seen the symbolic signs enough, the word signs are a good fallback. The goal is to maximize accessibility.

That's the thing I'm concerned about! In Europe you're not allowed onto the road unless you have already proven that you have memorised all the symbols and can identify them on demand. You don't need to maximise accessibility because the required level of education is higher.
The obvious benefit of the European style is that you don't need to speak the language in order to understand the signs, something that is clearly less important given the relative homogeneity of language in the USA.
But at least to me, the European road signs are also more quick to read. For example, the "only right turns" and "speed limit 60" are exactly the same shape and color in the USA, while in Europe there is more of a logical system (which also means you don't "memorize a bunch of symbols", you learn the "language" of the signs), such as blue disc means "mandatory", red circle means "prohibited", red triangle means "warning", etc.
No parking is usually a red curb or striped out area, which is different but also nonverbal. The complication is that many places have a EULA on parking spots that reads something like "No parking, 9-5pm, except on Tuesdays and full moons, or in a yellow vehicle, or by written agreement with a minimum of two signatures not including Bob". Good luck putting that in an icon.
That "no stopping" sign is unfamiliar to me, I guess we write it out but it's a pretty rare thing here to not allow stopping.
Most of the rest is familiar and/or obvious except the ones that have German words on them. Many of the concepts in writing don't exist on the German signs, I don't know if you don't have these signs or just not listed on your chart. Some of the English ones are just tooltips; it's never ok to stop on a railroad track but someone thought a reminder would be nice.
I have also noticed that parking rules are usually much simpler in the EU than in the US, and maybe the format just makes it cumbersome enough to spell out abstruse rules that in the end, the rules just have to stay simple enough.
It's not totally true though because lately many cities in France have enacted complicated parking rules that are explained nowhere except on a buried page on their website that might or might not be up to date. But that's just because modern societies are straying further and further away from the rule of law with every passing day, and there is nothing that citizens can do about it.
I mean... Europe had to develop a system that works regardless of whether you speak the local language. The USA assumed every driver would speak English. I would tend to favor the European strategy, though given how we've held out on adopting the metric system I won't hold my breath.
