What is the rule at this traffic-light-controlled junction with additional signage?

At the traffic-light-controlled junction depicted, the red traffic light indicates that vehicles must stop. However, the additional signage allows cyclists to turn right even when the light is red. This rule is based on German traffic regulations, which recognize cyclists' ability to proceed under specific conditions, promoting safer and more efficient navigation through intersections.

It's essential to understand that this specific permission applies to cyclists only, emphasizing their cyclists' rights in urban traffic scenarios. Motor vehicles, however, are still required to obey the red light and cannot turn right in this situation. Awareness of these rules helps ensure compliance and promotes safety for all road users.
