What must you do in this situation?

In this situation, you correctly chose that you must immediately brake sharply and not swerve. According to German traffic rules, when faced with a sudden hazard—such as an obstacle or an emergency—you should brake firmly to minimize the stopping distance and avoid losing control. Swerving, especially at speed and on rural roads, is risky because it can lead to collisions with oncoming traffic or obstacles at the roadside. Therefore, the safest and recommended reaction is to maintain your lane and perform an emergency brake rather than steering to the left or swerving, which could create additional dangers. This approach is emphasized in German driving instruction and helps prevent more severe accidents. Knowing this rule will help you respond predictably and safely in similar situations.
