What must you do when you are travelling and you notice that your vehicle is no longer roadworthy?

In German traffic rules, if you realize your vehicle is no longer roadworthy, you must first remove it from traffic as quickly and safely as possible to avoid endangering yourself and others. This means stopping or parking the vehicle where it causes no obstruction or risk. Second, you may only continue your journey once the vehicle has been repaired and is safe to drive again. It is not allowed to drive a vehicle that is unsafe or potentially dangerous. Going to the next authorized dealer without repair is not acceptable if the vehicle's condition affects roadworthiness, as this might increase the risk of an accident. These rules ensure safety for all road users.
