In this situation, when turning right at the intersection, are you obliged to stop before the traffic signal?

In the visible situation, the S-1 standard signal shows a green light, which allows you to enter the intersection without having to stop. A requirement to stop would only occur in the case of a conditional turn (S-2 green arrow) or a red light, but here we have a standard green light. According to Art. 5 para. 3 of the Road Traffic Act, traffic signals take precedence over signs regulating the right of way.
