The rear lighting systems of your car are covered. What has to be done?

You answered correctly. If the rear lighting, such as tail lights, brake lights, or indicators, is covered and therefore not visible, replacement lighting must always be attached before driving, no matter the time of day or the length of your journey. These lights are crucial for signaling your actions to other road users and for your own visibility, which ensures road safety at all times. It is not sufficient to fit them only at night or only for long trips—this requirement applies at all times when the original lights are obscured. This is a strict rule in Germany to prevent accidents.
