I’ve seen street signs like this in quite a few countries - this one’s in Morocco. They simply cancel the last sign you saw, whether it be a speed limit, a ‘no overtaking’ sign or whatever else. We don’t have them in Australia, and i find them interesting because they represent a fairly different ethos for road design.
Using these signs can be a lot simpler, because it doesn’t require the country to track as many existing road rules. Need to do some road work? Just bring a 30kph speed limit sign and a cancel sign - no need to know the speed limit in the area. Need to change the national highway speed limit? Just change the signs that talk about it - you don’t have to think about the thousands of variations that have been made, because they don’t actually refer to the national speed limit when they end.
What this does do, however, is transfer the administrative burden to the driver, who suddenly needs to remember what the road rules were as well as what they are. This stateful approach isn’t much of a problem when simply moving from a national speed limit to another and back, but changes inevitably accumulate over time and it’s not uncommon to have 3 or 4 nested speed limits. Some countries have decided that the extra mental burden isn’t worth it, while others have.
