In the Netherlands highway limits have been 120km/h for several decades. Around 2010 it was raised to 130km/h (a pretty pretty popular measure by most accounts). In the last few years it became clear that the country as a whole was emitting many nitrogen compounds in the air, so as an emergency measure in 2019 the maximum highway speed was lowered to 100km/h. But only on specific sections at specific hours of the day (6:00-19:00), which keeps confusing me on the few occasions when I drive on a highway (a few times a year). So I just default to always 100km/h on all highways.
