In conditions of a significant reduction in speed on the roadway, will the driver of vehicle 2 drive ahead of vehicle 3?

The provided illustration shows the left lane ending in conditions of significantly reduced speed (congestion), which obliges drivers to use the 'zipper merge'. According to Art. 22 para. 4a, the driver moving in the lane that continues is obliged to enable one vehicle from the adjacent lane to change lanes directly in front of them. In this situation, vehicle no. 2, located in the ending lane, has the right to enter the adjacent lane as part of the alternating merge principle.
