A country lane is a narrow road in the countryside. In North America and Australia, the term "lane" also may refer to rear access roads which act as a secondary vehicular network in cities and towns. Some towns and cities in the United Kingdom, including the City of London, also name some minor streets and passageways as a "Lane". However, the more usual British usage of the term "lane" is for a narrow road with little vehicular traffic in the countryside, within or between villages, and these can be named or remain unnamed. Some country lanes in the UK are not open to general traffic (or not paved, so not able to be used by most vehicles) and are called green lanes.
