You can park in any publicly accessible parking lot (free of charge within the business areas) of a city, the hvv switch points and in the designated areas at Hamburg Airport. In "parking ticket zones" please be sure to use a parking disc. A parking ticket is not required here. In designated "parking disc zones", the parking time is also limited. Please use the parking disc in your car and display it visibly. The rental period cannot be terminated in "parking disc zones", but intermediate parking is possible.
Comprehensive overviews of the basic parking rules can also be found at SIXT share, WeShare and MILES. Familiarize yourself with the parking rules and note that other rules apply outside the Hamburg business area.
Basically, the parking guidelines apply according to the locally valid road traffic regulations.
