Road signs are essential for maintaining order and safety on public roads. They come in various shapes, colors, and sizes to convey different types of information to drivers and pedestrians. Road signs include regulatory signs, such as speed limits and stop signs; warning signs, alerting to potential hazards like sharp curves or animal crossings; and guide signs, providing directions to nearby cities or points of interest. They are designed for easy visibility and are strategically placed along roadsides and intersections to ensure optimal communication with road users.
