What is the right course of action now?

In this situation, stopping is the correct action because something on the road—in this case, typically a traffic sign, a red light, or another traffic regulation—requires you to halt your vehicle. According to German traffic rules, you must always stop when a stop sign or a red traffic light is present, or in any situation where not stopping would endanger other road users or violate the law. Continuing to drive or accelerating would be unsafe and could result in a violation. Stopping ensures you observe any restrictions and keeps everyone safe. Recognizing situations where a stop is required is key for safe driving and passing the theory test.
