Vertical signs are signs that are oriented upright, typically displaying information or instructions to pedestrians and drivers. They are commonly used in various settings, such as streets, parking lots, and public spaces, to convey messages like traffic regulations, directional guidance, or safety warnings. These signs can be made from different materials, including metal, plastic, or wood, and often feature bright colors and clear symbols for easy visibility. Examples of vertical signs include stop signs, yield signs, and parking signs, which help maintain order and safety in both urban and rural environments.
