On the occasion of the recently planned regional driving bans for vehicles with a standing noise of over 90db and the closed petition thread (why in a discussion forum the discussion of topic-relevant things is stopped, unfortunately, withdraws my knowledge) I still have a question of understanding. Why is a measured standing noise taken as the basis for a driving ban. Shouldn’t one rather make a driving noise measurement? Apart from that, I as a driver have the noises In this way, my motorcycle can also move in the right hand with respect to the residents. Between times when driving, other things also have an influence on the noise levels perceived by outsiders, such as topography, construction, personal noise perception of the affected persons, etc.
