Dual carriageway Facts for Kids

A dual carriageway in Great Britain.

A dual carriageway is a type of road. It is an important route that usually carries long-distance traffic.

A dual carriageway has four lanes (2 lanes each side), and is always separated by a man-made barrier or strip of land.

Dual carriageways have no hard shoulder. A hard shoulder is an area at the side of a road where drivers can stop if there is a serious problem, a breakdown for example.
