The highway code specifies speed limits for different types of vehicle on different roads. In the UK the National Speed Limit for cars 60mph on single carriageway roads and 70mph on dual carriageways and Motorways. The term "national speed limit" means the top speed that is allowed on this particular type of road in this country. 30mph is the normal speed limit in a built up area where there are no other signs but street lights. A built up area is usually an area where the street lights are situated less than 200 metres apart.
