What must you do when a traffic jam forms on this road?

In Germany, when a traffic jam forms or traffic slows down significantly on a multi-lane road, you must create an emergency corridor (Rettungsgasse) to allow emergency vehicles to pass through quickly. On a two-lane road in each direction, this means that all vehicles in the left lane should drive as far to the left as possible, and all vehicles in the right lane should drive as far to the right as possible, leaving a clear central lane between them.

The purpose of this rule is to ensure that ambulances, fire trucks, and police can navigate through traffic jams without delay, which can be critical in emergencies.

So, driving as far to the left as possible (option 1) when a traffic jam occurs is correct because it helps form that emergency corridor. Driving in the center or to the right wouldn't create the necessary space for emergency vehicles.
