If you have filed a request (and also paid, where appropriate), a processing time of 10 days always applies. In those 10 days, you can enter the zone at your own risk. If the request is approved, the admission will take effect from the starting date indicated. If the starting date selected is a past date, then the approval will apply retroactively. If your request is denied and you entered the zone during the 10 days of the processing period, you will be fined. Therefore, make sure that you provide the correct information.
