The federal and state governments have decided that in order to contain the corona pandemic in counties with an incidence of more than 200 days or more, the range of motion should be restricted to 15 kilometers around the place of residence. With this map tool you can see which areas the 15 kilometer radius would cover in your case. Simply enter your postcode in the search field.
For good reasons – such as visits to the doctor or the way to work – the range of motion should of course be exceeded. However, this should prevent day trips in particular. More information on this is available at tagesschau.de.
In addition, it has not yet been conclusively clarified in the federal states whether, in large cities like Hamburg, the actual place of residence defines the center of the radius or the city or district boundary. Then the radius of movement of the residents there would be significantly larger.
