Wide outside lane
Awide outside lane(WOL) orwide curb lane(WCL) is anoutermost laneof a roadway that is wide enough to be safely shared side by side by abicycleand a widermotor vehicleat the same time. The terms are used by cyclists and bicycle transportation planners in the United States. Generally, the minimum-width standard for a WOL in the US is 14 feet (4.3 m).[1]Awide outside through lane(WOTL) is a WOL that is 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 motor vehicle. When the outside lane of a roadway is a narrow lane, it is sometimes referred as anarrow outside lane(NOL),narrow curb lane(NCL) ornarrow outside through lane(NOTL).
Legal definitions[edit]
The US Department of Transportation'sFederal Highway Administrationdefines a "Shared Lane" as follows:
- Shared Lane—A lane of a traveled way that is open to bicycle travel and motor vehicle use.
- Narrow Lane—A travel lane less than 14 feet in width, which therefore does not allow bicyclists and motorists to travel side-by-side within the same traffic lane and maintain a safe separation distance.
- Wide Curb Lane—A travel lane at least 14 feet wide, adjacent to a curb, which allows bicyclists and motorists to travel side-by-side within the same traffic lane.[2]
Rules of the road[edit]
In some jurisdictions, the rules of the road apply differently for a cyclist when the roadway has a WOL or a NOL. For example, in the state ofCaliforniaall cyclists are legally required to ride "as close as practicable to the right-hand" side of the roadway when the lane is wide enough "for a bicycle and a vehicle to travel safely side by side within the lane." While California does not specify exactly what constitutes "wide enough", other states do. For example, the Texas version of this law states that riding "as near as practicable to the right" is not required when a variety of conditions are present, including when "the person is operating a bicycle in an outside lane that is less than 14 feet in width".[3]Experts onvehicular cycling[who?]recommend that cyclists not share marked lanes that are not wide enough for efficient, safe, and lawful passing within the lane - that instead they shouldcontrolsuch lanes (by riding in the middle) that are too narrow for safe side-by-side sharing by motor vehicle and bicycle both within the lane.[citation needed]
Benefits and drawbacks[edit]
WOLs are generally considered[who?]to be facilities which primarily benefit cyclists[citation needed];for a road marked with abike lane,if the bike-lane stripe is removed, what remains is a WOL. Some[who?]vehicular cyclistsandbike lane opponentsadvocate for WOLs instead of bike lanes, arguing that WOLs provide most, if not all, of thebenefits,without many of the perceiveddrawbacksthat bike lanes impose on people travelling by bicycle. Still others[who?]maintain that the primary purpose of providing the additional roadway width—whether in the form of a WOL or a bike lane—is to facilitate the passing of cyclists by motorists.
