Street lines are painted markings on the surface of roads and streets to guide and direct traffic. They serve various purposes such as indicating where vehicles should drive, separating lanes of traffic, designating parking spaces, and signaling crosswalks for pedestrians. The most
common types of street lines include solid white or yellow lines, which separate lanes of traffic traveling in the same direction, and dashed white lines, which indicate that drivers may pass other vehicles when it is safe to do so. Street lines are an essential part of traffic management and help to ensure the safety of drivers and pedestrians on the road.
