One surprising (after we got a ticket..) thing about parking laws in Sweden is that you're also only allowed to park on the right side of the road / with the car in the direction of the traffic. This has the benefit of that when you're leaving the street parking, you are sitting close to the lane and can look behind you for coming cars and only cross one lane. Compared to parking on the "wrong" side, where you're sit…
As a Swede it amazes me that some countries allow parking "in the wrong direction". I've never even thought about it, and I don't know if it's a written rule (I'm sure it is, just it;s been a long time since I got my license).
I believe many Norwegians have received parking tickets when visiting Sweden because if this difference. I wasn't aware of this myself until recently.
