Since the 7-day incidence rate has been shrinking throughout Germany, the "Federal Emergency Brake" with night curfews and strict contact restrictions no longer applies. However, there are still contact restrictions and some other regulations. The rules are now again determined by the individual federal states. You can find current rules in your federal state at corona-was-darf-ich.de in many languages. You can find out more about current rules in your federal state at the website of the German Chamber of Commerce & Industry in German.
Important: The police is tasked to enforce compliance with corona rules. Those who break these rules face a penalty which can range from a fine to a prison sentence. Some of the above rules no longer apply to vaccinated or recovered people. You can find out more about this in the section “What rules apply to vaccinated and recovered individuals?”.
