What is a unique feature of a motorway regarding lanes?

A unique feature of a motorway is that it is designed to accommodate multiple lanes for vehicles, which are often divided by safety features such as barriers or painted lines. This multi-lane structure enhances the flow of traffic, allowing for efficient movement, particularly at higher speeds. The lanes provide separate paths for different types of vehicles and allow for overtaking maneuvers, which is crucial for maintaining speed and reducing congestion.

Additionally, this design includes safety aspects that separate opposing flows of traffic and provide refuge for vehicles that may need to stop, further enhancing the safety of motorway travel. This multi-lane arrangement, along with the added safety features, is essential for the efficiency and safety of high-speed road travel, setting motorways apart from other types of roads that may have fewer lanes and less separation between oncoming traffic.
