What number of trailers may be towed behind a car?

You are correct: In Germany, a car is generally allowed to tow only one trailer at a time. This rule applies to standard passenger vehicles. Towing more than one trailer is not permitted for cars, as it would reduce road safety and maneuverability. Only specific vehicles, such as certain agricultural vehicles, may tow more than one trailer under strict conditions. For everyday driving with a regular car, you must always stick to just one trailer. This rule helps ensure safe and predictable traffic flow.
