Which users must obey the traffic light in the photograph?

# Explanation The traffic light shown in the photograph is a **bicycle traffic light**, identifiable by its shape and specific symbols. This type of traffic light is designed exclusively to regulate the traffic of bicycles and mopeds, which are the users who must obligatorily obey it. Pedestrians have their own traffic lights, and other motorised two-wheeled vehicles (motorcycles) must follow the conventional traffic lights for cars.
