B-roads are minor roads in the United Kingdom and other countries, typically used for local traffic. They connect smaller towns and rural areas, providing access to places that may not be served by major highways. B-roads are usually less busy than A-roads and often have lower speed limits. These roads can vary in quality and width, with some being narrow and winding. B-roads play an essential role in the transportation network, allowing for the movement of goods and people while also offering scenic routes for travelers exploring the countryside.
