This is usually the case if the road has no space for a total of four lanes, but has enough space for three.

The two sides then change over longer distances, so that each one gets an overtaking track.

On a shorter distance, this may not be sufficient to ensure it for both directions.

This is often where a road opens or rises so that you can overtake the then particularly slow trucks.

It is often so that you can overtake the section, eg when a busy federal road goes uphill, the traffic can pass by the slower trucks.

This is an overhaul for the other direction.
