Hotspots are parking spaces reserved only for GreenMobility - Your City Car. Here you can always end your trip and often also find a free City Car.
You can always park for free on all public parking spaces with a time limit of minimum 2 hours within the Zone. Notice that there is a few outer parts of the Zone where you pay to finish your trip. See the areas here. For area-specific rules see below.
You can not park on private parking spaces unless it is a Hotspot. You recognize private places on the black parking signs. Read more by clicking below.
