Well, yeah. There are guidelines for new infrastructure, but that doesn’t mean everything is up to date everywhere. There are roads that haven’t been resurfaced for quite a while that aren’t up to date. But on the whole it is very similar everywhere.
It’s only a small country though.
There is a Canadian YouTuber who lives in Amsterdam who makes videos about it: http://YouTube.com/notjustbikes I’ve lived here all my life so it’s nice to get an outside perspective on this all.
In Europe (in my case the Netherlands, but it’s similar in surrounding countries) you cannot pass on the right and you can get fined for it. If you do pass on the right you’re taking a bigger risk because it is not expected.
You can also get fined for staying in the left or middle lane for too long. But that’s somewhat rare. You can get away with it a bit to pass an extra truck (our trucks speed limit is slower) or if the right lane is full and slower than the lane to the left of it, but don’t drive excessively slow on the left. Especially on the Autobahn.
