Various signs in this photo. Starting from the left, the white and red direction sign is for slow traffic pointing to South Amsterdam , West Amsterdam, Haarlem and Zaanstad.
The flags are there because the Netherlands are chairman of the European Union (EU) for half a year and have their meetings in Amsterdam now. Every member of the EU is a chairman each half year and this is the twelfth time for the Netherlands.
Then there is a red sign in the front warning not to place your bike or motorbike outside the parking facilities. Amsterdam tries to handle the tsunami of parked bicycles everywhere in the streets. The not correct parked bikes are transported to a remote area where you can get your bike after paying a fine.
