What is the right course of action now?

You answered correctly by choosing to remain behind the tractor and to anticipate that it may turn off the road. According to German traffic rules, when following a slow-moving agricultural vehicle on a rural road, it is important to keep a safe distance and exercise patience. The tractor may need to turn or maneuver unexpectedly, so being alert to its signals or possible actions helps you react safely.

You should not overtake the tractor unless it clearly signals and the road conditions allow a safe passing maneuver. Since the tractor did not give an overtaking signal and there was oncoming traffic, staying behind is the safest and legally correct choice. This approach prevents accidents caused by misjudging the tractor’s intentions or attempting unsafe passing on a two-lane road.

In summary, maintain a safe following distance, observe the tractor’s signals or road position for possible turns, and only overtake when it is clearly safe and permitted. This ensures smooth traffic flow and safety for all road users.
