There are specific real-estate arrangements made to allow vehicles to travel from one place to another . The most common such arrangements are public highways , where appropriately licensed vehicles can navigate without hindrance . These highways are on public land and are maintained by the government . Similarly , toll routes are open to the public after paying a toll . These routes and the land they rest on may be government or privately owned or a combination of both . Some routes are privately owned but grant access to the public . These routes often have a warning sign stating that the government does not maintain the way . An example of this are byways in England and Wales . In Scotland , land is open to un-motorised vehicles if the land meets certain criteria . Public land is sometimes open to use by off-road vehicles . On US public land , the Bureau of Land Management ( BLM ) decides where vehicles may be used . Railways often pass over land not owned by the railway company . The right to this land is granted to the railway company through mechanisms such as easement . Watercraft are generally allowed to navigate public waters without restriction as long as they do not cause a disturbance . Passing through a lock , however , may require paying a toll . Despite the common law tradition '' Cuius est solum , eius est usque ad coelum et ad inferos '' of owning all the air above one 's property , the US Supreme Court ruled that aircraft in the US have the right to use air above someone else 's property without their consent . While the same rule generally applies in all jurisdictions , some countries such as Cuba and Russia have taken advantage of air rights on a national level to earn money . There are some areas that aircraft are barred from overflying . This is called prohibited airspace . Prohibited airspace is usually strictly enforced due to potential damage from espionage or attack . In the case of Korean Air Lines Flight 007 , the airliner entered prohibited airspace over Soviet territory and was shot down as it was leaving
