The "End of a bicycle zone" sign indicates that the designated area for cyclists has come to an end. In a bicycle zone, certain rules apply that prioritize the safety and movement of cyclists, such as reduced speed limits for motor vehicles and specific bicycle paths. Once you pass this sign, cyclists are no longer subject to the special regulations of the bicycle zone, and normal traffic rules apply. This means that cyclists might now have to share the road with motor vehicles more freely and will not have the same protections as they did within the bicycle zone. Always be cautious and watch for cyclists when entering or exiting these areas. If you have any more questions about traffic rules or other signs, feel free to ask!
