Should you in all situations stop before the sign "giving priority to vehicles approaching from the opposite direction"?

In the video, you are driving on a road in a town and approaching a narrow passage under a railway viaduct; on the right there are signs B-33 "speed limit" of 30 km/h and B-31 "priority for oncoming vehicles". You do not have to stop before sign B-31 in every situation - only when a vehicle is coming from the opposite direction. The answer is: no.

The Regulation on road signs and signals states that sign B-31 "priority for oncoming vehicles" prohibits road users from entering the narrowed section of the roadway, by vehicle or on foot, if this would force drivers who are on that section or approaching it from the opposite side to stop. So the sign does not require an absolute stop like B-20 - it requires you to give way. When the narrowing is clear and nobody is coming from the opposite direction, you drive through without stopping, slowing down to 30 km/h in line with sign B-33; when a vehicle is coming from the opposite direction or someone is already on the narrowing, you stop before the sign and wait until the section is clear. On the other side of the narrowing there is sign D-5, which gives priority to those drivers. Before entering, you look deep into the passage under the viaduct.
