You can always park your Poppy car in the Poppy zones. In the Poppy zones, you can leave your car in every legal public parking spot. You can also park your car in every place where you normally need a parking card or a resident card, without having to show anything. 🙌🏻
In the Poppy zones of Antwerp, Mechelen or Brussels, it is not necessary to pay for a car park ticket in a public area except for the red zones (commercial areas - visible in the app). 🎉
So you can park for free in a public area in the Poppy zones, but there are also some places where you are absolutely not allowed to park. You can find them here.
