What is true in the case of this traffic sign combination?

The combination of the yield sign with the supplementary sign showing a bicycle indicates that you must give way not only to motor vehicles but also to cyclists coming from both the left and right directions. This includes electric scooters, which are often classified similarly to bicycles in traffic rules. Therefore, you need to watch out for and yield to all non-motorized traffic on the intersecting road, not just motor vehicles on the priority road. This rule helps ensure safety for vulnerable road users like cyclists and e-scooter riders.
