Svenska vägtrafikförordningen

Vehicles or trams may not overtake directly before or on an unguarded pedestrian crossing In the following cases, it is not considered overtaking when a vehicle in one lane passes a vehicle in another lane

if the carriageway has two or more lanes for travel in the same direction and there is a heavy traffic queue in all lanes.
if the carriageway is divided into lanes for different destinations that are marked with a lane assignment sign, or
if the vehicles have been placed in separate lanes in connection with a junction.

It's worth mentioning that the second exception specifies that the lanes must travel to different destinations, not the same one
