In this situation, should you stop before the visible line of absolute stop - stop?

In the video, you are approaching a junction with traffic lights in a town; the traffic lights are showing green, there is sign B-20 "STOP" on the corner, and a stop line is painted on the roadway before the junction. You should not stop before the visible mandatory stop line - the traffic lights are working and you have a green light. The answer is: no.

The Road Traffic Act states that light signals take precedence over road signs that regulate right of way, and the Regulation on road signs and signals states that a green signal means permission to proceed past the traffic lights. Sign B-20 and the line P-12 related to it apply only when the traffic lights are switched off or showing flashing amber; then the junction goes back to the rules set by the signs, and you must stop before the line without exception. When the traffic lights are working, stopping on green would be not only unnecessary but also dangerous - the driver behind you does not expect it. However, green does not allow you to enter when there is no room beyond the junction to leave it. So you drive through smoothly, watching the crossing and the vehicles at the junction, and you remember sign B-20 in case the lights ever stop working.
