2 warnings for 1 event

Hello together This is now a “legal” question, but it is not about a concrete consultation, only about a general information. So maybe someone can help me… Can one be warned twice in a short time because of the same facts? For example “AU exceeded by more than 2 months”, received a warning on Tuesday from the municipal traffic monitoring and on Wednesday from the traffic police, each over 15 euros. In the criminal law applies yes r Principle “Ne bis in idem”, i.e. that you cannot be punished twice for the same act. Is this also true in traffic law, or do you have to pay both warnings at the end? Thank you in advance and greeting Lars
