In the United Kingdom, the second tier of high speed roads below "Motorways" are typically dual carriageways. Many roads such as the A1, the A14, the A19 and the A42 are built to a high quality, in many places they are only intersected by grade-separated junctions, have full barriers at both the road side and the central reservations and in some cases three or more lanes lanes of traffic, however they are not subjected to motorway restrictions as they are typically built to a lower standard, or have existing right of way rights for non motorised vehicles. They may lack some features that a motorway would have, such as hard shoulders, and may have tighter bends and steeper gradients than would be allowed on a motorway or have established rights of way that cannot be removed. The standard motorway speed limit for cars of also applies to many dual carriageways.
