Personal liability insurance is often taken out together with contents insurance. This insurance is definitely recommended: it isthere for damage that you mistakenly inflict upon others - if you were stumble, for example, and knock an antique vase off its pedestal or put a burn in the carpet of a hotel room. If something "stupid" happens, so to speak.
But there are also situations that should not happen: for example, if you run a red light on your bicycle and injure a pedestrian or if you light a candle, then leave the house and the building catches fire. Such behavior is considered gross negligence - and in such cases insurers have the right to reduce their benefits.
Tip: Be sure to include gross negligence cover with your personal liability. After all. who can completely rule out the possibility of something really stupid happening to them? The extra few francs are a good investment and ansure that you receive the best possible protection - even if your mind was somewhrer else entirely for a moment.
