In Ontario a new speed zone is always signed with "BEGINS" below it, which is very helpful if you missed the last sign. I wish this was standard practice across Canada.

In much of Europe, including the UK, they have the concept of standardised "national" speed limits, which vary depending on the road type and which you are expected to know. When a road returns to the national speed limit, the sign is a white circle with a slash through it, indicating that there are no more local speed limits and the national speed limit is in effect.

There are at most three standard speed limits on Europe: built up areas, highways and motorways.

I find this easier to remember than the constantly changing limits in the USA. In my two weeks here, I've seen every multiple of 5 between 5 and 70mph.

In Sweden at least, there's an informal rule that a new speed zone is marked with speed limit signs on both sides of the road, whereas a continued limit is marked with a sign only on the driving side of the road.

I never quite saw the point though -- my response is the same either way: adhere to the limit that applies going forward. (I suppose maybe it's useful feedback of inattention and the need for rest?)
