Symbols Maximum speed 40 km/h

Hello Together I have a question. I was on a radar trap of the police out of probably wrong knowledge earlier. I was on the two-lane slightly downhill road outside the city on the right lane with about 51 kmh on my jet force. On the left lane on the roadside there was a speed limit sign with 40 kmh. On the right where I drove none. So I didn’t care. As it had to come, race management waved me out. I would have been 8 kmh too fast. I s I didn’t think I had a speed limit on my side. He meant the sign on the left was enough. I reluctantly paid the small money because I didn’t want to argue. If I had, they would have taken the scooter for the time being, as Agro as they were on it. But now the question. On two-lane roads, must there be a speed limit sign on both sides, or at least not only on the left one, right?
