Norway is similar to Germany when it comes to traffic lights.
Yellow being a transitional indicator so drivers (and pedestrians to some extent) can know slightly ahead that it's either gonna turn green or red in a few sec.
Also blinking yellow means free drive, usualy happens during maintainance/error,
or and certain times of the day when they basicaly allows "free drive".
(very odd to see, I've seen it a few times like middle of night downtown etc. kinda "the day after" feeling

Pedestrians here though only have stop and go. (red stick man and green stickman)
Basically car traffic lights here mean:
Green = go
Yellow = Get your ass out of the intersection/road right now.
Red = You'd better not be anywhere near here or your dad buddy.
Or alternatively (as a standup commedian said... George Carlin I think):
Green means go,
yellow means go faster,
red means peddal to the metal.
