"Yellow tape" typically refers to a type of barrier tape that is bright yellow and often marked with the words "Caution" or "Police Line Do Not Cross." It is commonly used at crime scenes, construction sites, or hazardous areas to indicate that entry is restricted and to ensure public safety. The color yellow is chosen for its high visibility, making it easy for people to see from a distance. In law enforcement, yellow tape serves as a visual cue to keep unauthorized individuals away from sensitive areas. It helps preserve evidence at crime scenes and allows investigators to work without interference. The use of this tape is a standard practice in many countries to maintain order and safety during investigations or construction activities.
