The roads in the United Kingdom are an extensive network that includes motorways, A roads, and B roads. Motorways are major highways designed for fast traffic, while A roads connect larger towns and cities. B roads are smaller routes that link local areas. The UK uses a left-hand driving system, meaning vehicles drive on the left side of the road. Road signs are standardized and include important information such as speed limits and directions. The Highways Agency is responsible for maintaining the motorways and major roads, ensuring safety and efficiency for all road users.
