Pavement markings are visual indicators on road surfaces that guide and regulate traffic. They include lines, symbols, and words painted on the pavement to convey important information to drivers and pedestrians. Common types of pavement markings include lane lines, crosswalks, and stop lines. These markings help maintain order on the roads by indicating where vehicles should drive, where to stop, and where pedestrians can safely cross. They are essential for road safety and are often made from durable materials to withstand weather conditions and heavy traffic.
