Afaik there's only 1 motorway in the UK with a roundabout and it's at the end where it becomes a normal road again. Usually if there is a roundabout on a dual carriageway it's because it's connecting to a single carriage way that could be anything from a 60mph bypass road for a town to a 20mph residential street.
