to adequately cover a particular risk. BrE uses the word "cover" for both the noun and verb forms. Transport AmE speakers refer to transportation and BrE speakers to transport. (Transportation in the UK has traditionally meant the punishment of criminals by deporting them to an overseas penal colony.) In AmE, the word transport is usually used only as a verb, seldom as a noun or adjective except in reference to certain specialised objects, such as a tape transport or a military transport (e.g., a troop transport, a kind of vehicle, not an act of transporting). Road transport Differences in terminology are especially obvious in the context of roads. The British term dual carriageway, in American parlance, would be divided highway or perhaps, simply highway. The central reservation on a motorway or dual carriageway in the UK would be the median or center divide on a freeway, expressway, highway or parkway in the US. The one-way lanes that make it possible to enter and leave such roads at an intermediate point without disrupting the flow of traffic are known as slip roads in the UK but in the US, they are typically known as ramps and both further distinguish between on-ramps or on-slips (for entering onto a highway/carriageway) and off-ramps or exit-slips (for leaving a highway/carriageway). When American engineers speak of slip roads, they are referring to a street that runs alongside the main road (separated by a berm) to allow off-the-highway access to the premises that are there; however, the term frontage road is more commonly used, as this term is the equivalent of service road in the UK. However, it is not uncommon for an American to use service road as well instead of frontage road. In the UK, the term outside lane refers to the higher-speed overtaking lane (passing lane in the US) closest to the centre of the road, while inside lane refers to the lane closer to the edge of the road. In the US, outside lane is used only in the context of a turn, in which case it depends in which direction the road is turning (i.e., if the road bends right, the left lane is the "outside lane", but if the road bends left, it is the right lane). Both also refer to slow and fast lanes (even though all actual traffic speeds may be at or around the legal speed limit). In
