Double-decker bus

A double-decker bus is a large vehicle designed with two levels for passengers, allowing more people to travel simultaneously. Common in cities like London, it features an open-top or enclosed upper deck providing additional seating and views. Its design maximizes passenger capacity within a standard road space, making it efficient for busy urban routes. Double-deckers are especially useful in areas with high demand for transportation, offering a practical combination of capacity and maneuverability while contributing to iconic cityscapes.
