A freeway is a type of road designed for safer high-speed operation of motor vehicles through the elimination of at-grade intersections. This is accomplished by preventing access to and from adjacent properties and eliminating all cross traffic through the use of grade separations and interchanges; railroad crossings are also removed. Such highways are usually divided with at least two lanes in each direction. Because traffic never crosses at-grade, there are generally no traffic lights or stop signs. Some countries have roads that function as freeways but use different names. These include autobahn, autovía, autoroute, autopista, autostrada, autosnelweg, motorway (in the UK and Ireland) and expressway (in India and Asia).
