Abstract: A flag warning system is paramount because it increases the safety of a dock-loading area. Often times, workers and machinery are moving in and out of trailers to either load or unload trailers, and it is important to insure that the truck is not moved inadvertently, thereby preventing damage to individuals and equipment. This is a simple dock warning system that will alert the driver by simply rotating a flag so that the flag is either visible or not visible to alert the driver to move or not move the trailer. When the flag is visible to the driver when he or she looks in the rearview mirror, the load is safe to be pulled. If the driver does not see the flag, he or she should not pull the load.
