IN the United States of America, wide outside lane (WOL), or wide curb lane (WCL), is a term used by cyclists and bicycle transportation planners to refer to the outermost lane of a roadway when it is wide enough to be safely shared side by side by a bicycle and a wider motor vehicle at the same time. GEnerally, the minimum width standard for a WOL is 14 feet (4.3 m). A WOL May also be known as a wide outside through lane (WOTL) to differentiate it from a right turn only lane (an outermost lane for traffic that will turn right, not intended for use by through traffic). COnversely, a narrow lane is a lane that is too narrow to be safely shared side by side by a bicycle and a wider motor vehicle at the same time. WHen the outside lane of a roadway is a narrow lane, it is sometimes referred as a narrow outside lane (NOL) or a narrow curb lane (NCL). TO encompass only through lanes, the term narrow outside through lane (NOTL) is sometimes also used.
