A standard traffic sign meant to give straightforward directions so people can find places, services, or roads more easily. These signs are made of tough, rust-proof aluminum, then covered with reflective material - either basic or brighter grade - for better sight when it's dark or rainy. They use letters, arrows, and colors that follow MUTCD rules, usually showing white words or icons on green surfaces, making them simple to read even while moving fast. Built to last outside over time, they guide drivers safely by pointing out where to turn, which lanes go where, how routes link up, and what’s ahead - all helping folks decide quickly and correctly while driving.
