Hello, today I drove towards a traffic light, where a sign was standing “Keep the mouth free”. The entrance was right at the front of the traffic light. I stopped right at the sign. After 5 seconds a BMW with an older gentleman stopped behind me, which permanently horned at me. So after 20 seconds he overtook me at the traffic light daringly with danger, because from opposite traffic came. When he stood then in front he tore the door open and mooted that one had to run over the contact strip, dami I said to him that a) the sign was then nonsense and b) such a contact strip only applies in the evening/night with little traffic and the traffic light also switches during the day. 5 seconds later it also became green, because we were sneaky. First the left, then the right, then we. Quite normal. Now he meant of course that the traffic light switched because he overtakes me. What’s right now? If I’m wrong, they should change the sign. If you turn the traffic light on. I can’t run over the contact strip. Thank you and greeting, IMHOtep
