What is the difference between a motorway and a dual carriageway?

A motorway is a high-capacity roadway designed specifically for fast-moving traffic, featuring multiple lanes, no intersections, and restricted access points. In contrast, a dual carriageway consists of two separate roadways for opposing traffic, often with limited access, but can include intersections and may allow for lower speed limits. Motorways typically have stricter regulations, such as prohibiting certain vehicles and requiring a higher minimum speed. Overall, motorways prioritize safety and efficiency for long-distance travel, while dual carriageways provide a balance between traffic flow and local accessibility.
