The term 'street coverage' can be summarized as the process of covering a street with a layer of TAR. TAR is a type of material that is used to seal and protect surfaces from water, dirt, and other elements. It is often used in road construction and maintenance projects. TAR is also used to create a waterproof layer on roofs and other surfaces. Street coverage is an important part of maintaining roads and ensuring that they are safe for drivers and pedestrians.
