When a projecting load extends four or more feet beyond the bed of the vehicle during the daytime, the extreme rear and sides of the load must be marked with red flags. These flags should be at least 12 inches square and positioned to ensure visibility to other drivers. This is important for safety to alert others to the extended load.
