Be prepared to pay a 400 crown fme if you do not have a ticket and if you do not pay they might just drag you off to the Police Station. Please lock up you car and don't forget to put on your alarm, car theft is common and especially for foreign cars. If you are staying in an apartment for a period of time a short term Parking permit can be obtained at the nearest police station.
Permits are also available for the disabled here.
