Traffic barricades are physical barriers used to control and direct vehicle and pedestrian traffic. They are commonly made from materials like plastic, metal, or concrete and are often brightly colored for visibility. Barricades help ensure safety during road construction, accidents, or other emergencies by preventing access to hazardous areas. These barriers come in various shapes and sizes, including traffic cones, roadblocks, and fencing. They are essential for maintaining order on roads and highways, guiding drivers and pedestrians away from dangerous zones. Proper use of traffic barricades can significantly reduce the risk of accidents and improve overall traffic flow.
