What is the right course of action?

In this situation, the best action is to slow down when you encounter any uncertainty or potential hazards in urban traffic. Reducing your speed gives you more time to react to unexpected situations, such as pedestrians stepping onto the road from between parked cars or an oncoming vehicle making a sudden move. Accelerating or swerving can be dangerous, especially with oncoming traffic and parked vehicles narrowing the lane. Slowing down is the safest and most appropriate response, as it ensures you stay in control and able to react to any potential dangers on a busy or narrow street. This is a basic rule in German traffic: always adjust your speed to match the road, traffic, and visibility conditions for maximum safety.
