What does road marking Y4 indicate?

Road marking Y4 signifies a painted island where vehicles are prohibited from driving or stopping. This marking is commonly used to improve road safety by clearly delineating areas that should remain unobstructed, such as pedestrian crossings or refuges. The presence of this marking informs drivers that these zones are not intended for vehicle movement or parking, thereby preventing potential accidents and ensuring the safe passage of pedestrians and other road users. Understanding the importance of keeping these areas clear is crucial for safe and efficient traffic flow, as well as for the protection of vulnerable road users.
