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

The illustration shows a situation where the left lane ends in traffic congestion, which obliges drivers to apply the 'zipper merge' principle. According to Art. 22 para. 4a of the Road Traffic Act, the driver of vehicle no. 3 (in the continuing lane) is obliged to enable one vehicle from the ending lane (vehicle no. 2) to change lanes directly in front of them. Therefore, vehicle no. 3 does not pass first, but must let vehicle no. 2 through.
