B Roads are minor roads in the United Kingdom that are designated for local traffic. They are typically narrower than A Roads and are often used to connect smaller towns and villages. B Roads can vary in quality and may have lower speed limits, making them suitable for local travel rather than long-distance journeys. These roads are part of the national road network and are usually maintained by local authorities. B Roads play a crucial role in providing access to rural areas and supporting local economies by facilitating the movement of goods and people within communities.
