A bus lane is a designated lane on a roadway specifically reserved for buses and, in some cases, other authorized vehicles like taxis or bicycles. These lanes help improve public transportation efficiency by allowing buses to bypass regular traffic, reducing delays and encouraging more people to use public transit. Bus lanes are typically marked with signs and painted lines, indicating their purpose. They may be in effect during certain hours or all day, depending on local regulations. By prioritizing buses, cities aim to enhance mobility, decrease congestion, and promote environmentally friendly transportation options.
