Large, dual carriageway road with special status (in UK, Ireland, Australia). International equivalents: Interstate, Autobahn, autostrada. No stopping, u-turns, etc. Maximum speed limit (in UK) 70mph/110kph. In practice the police leave you alone up to 100mph/160kph. No speed cameras are allowed on ordinary motorways (eg no roadworks, or otherwise reduced speed limits). Due to poor planning and low government spending on all transport, UK motorways are notoriously congested (the busiest stretch or road in Europe, the M6 through Birmingham, has only 3 lanes each way).
