Who has stopped incorrectly?

In this scenario, the stopping of both the red and yellow cars is considered incorrect according to German traffic rules. The primary rule here is related to pedestrian safety at crosswalks. Drivers must stop before the crosswalk when pedestrians are present or when they might be crossing, ensuring their right of way and safety.

The yellow car is directly in front of the crosswalk and appears to be blocking it, while the red car is also positioned close enough that it could obstruct pedestrians. Therefore, selecting both cars as having stopped incorrectly reflects the requirement that neither should obstruct the crosswalk.

Understanding this helps underscore the importance of ensuring that vehicles do not impede pedestrian traffic, which is crucial in urban areas to promote safety for all road users.
