The word lane has several meanings, including and especially:
#a portion of a paved road which is intended for a single line of vehicles and is marked by white or yellow lines.
#a narrow road or street, usually lacking a shoulder or a median; this is typically applied to roads in the countryside, but can also be applied to urban streets or areas that used to be streets, such as Drury Lane in London, the Brighton Lanes, or the Cathedral Lanes in Coventry.

In Northern America and Australia, the term also may refer to rear access roads which act as a secondary vehicular network in cities and towns. Large cities in the U.S. states of Nevada and Texas tend to apply the term to many arterial roadsFact|date=February 2007. Also see alley.

In contrast to countries such as India, most countries with a significant number of motor vehicles have lane markings on their freeways, highways, and other types of paved road. A marked lane is a control device to guide drivers so that conflicts during passing are kept to a minimum. Lane markings also facilitate orderly queuing when drivers must stop and wait before proceeding.

When lanes are marked, drivers are usually required to keep their vehicle within the lines unless passing or turning. In many countries, a prolonged inability to stay in one's lane is considered to be a symptom of driving under the influence and may lead to a citation or arrest for a moving violation.

Types of lanes

*A traffic lane or travel lane is a lane for the movement of vehicles traveling from one destination to another, not including shoulders and auxiliary lanes.

*A through lane or thru lane is a traffic lane for through traffic. At intersections, these may be indicated by arrows on the pavement pointing straight ahead.

*A carriageway is a series of lanes (or part of a road) in which vehicles travel.

*A deceleration lane is a paved or semi-paved lane adjacent to the primary road or street. It is used to improve traffic safety by allowing drivers to pull off the main road and decelerate safely in order to turn (e.g. right in the United States or left in Great Britain), so that the traffic behind the turning vehicle is not slowed or halted. Deceleration lanes are primarily found in suburban settings.

*A fire lane is the area next to a curb, which is reserved for firefighting equipment, ambulances, or other emergency vehicles. Parking in these areas, often marked by red lines, usually warrants a parking ticket.

*A loading lane is an area next to a curb, which is reserved for loading and unloading passengers. It may be marked by a "LOADING ONLY" sign or a yellow or white curb.

*A passing lane is often provided on steep mountain grades, in order to allow smaller vehicles to pass larger, slower ones. This is sometimes called a climbing lane if on the uphill side. Passing lanes may also be provided on long stretches of other roadway. On two-lane roads, passing in the lane of oncoming traffic is sometimes allowed given a long enough straightaway, if the broken line is on the normal side of travel.

*A collector lane of a road is used for slower moving traffic and has more access to exits/off ramps.

*An express lane of a road is used for faster moving traffic and has less access to exits/off ramps. In other areas, an express lane may refer to a HOV lane (see below).

*A transfer lane of a road is used to move from express lanes to collector lanes, or vice-versa; it is somewhat similar to an auxiliary lane.

*A merge lane is a lane or onramp used to merge two flows of traffic into one, with the merge lane being the lane that disappears at the end of the merging area. Merge lane lengths depend mainly on the speed differential of the two merging flows, as the slower flow has to use the lane to accelerate.

*An auxiliary lane along a highway or motorway connects slip roads, with the entrance ramp or acceleration lane from one interchange leading to the exit ramp or deceleration lane of the next.

*The emergency lane of a road (also known as the breakdown lane, shoulder or hard shoulder) is reserved for breakdowns, and for emergency vehicles. The inner boundary of the lane often features rumble strips in order to physically warn drowsy or inattentive drivers that they are drifting off the roadway. This feature is seen especially often on highways and motorways, where the minimally-stimulating and monotonous nature of high-speed driving at night increases the chances for driver disorientation and serious injury or death if an accident does take place.

*An HOV lane or carpool lane is reserved for carpooling. In the US, they may be marked with a diamond icon every few hundred feet (hence the nickname "diamond lane"), or separated from other lanes by double broken white lines, a continuous pair of double yellow lines, or just a single broken white line.

*A High-Occupancy Toll lane is a combination of an HOV lane and toll collection technology that allows drivers without passengers to use the HOV lane by paying a premium price for the privilege.

*A turn lane is set aside for slowing down and making a turn, so as not to disrupt traffic. At a full intersection with a traffic light, turn lanes are used more to hold traffic until the light changes.

*A is a portion of the roadway or shoulder designated for the exclusive or preferential use of bicyclists. This designation is indicated by special word and/or symbol markings on the pavement and "BIKE LANE" signs.

*A bus lane is reserved for buses providing public transportation on a fixed route, sometimes with overhead catenary for trolleybuses. In some countries, bus lanes may also be used by some other traffic, such as taxis, bicycles and motorbikes.

*A reversible lane, which uses overhead lights, signs, poles or barriers to indicate the current direction of travel it is to be used for. Typically, it is used at rush hour to accommodate extra traffic, and at other times as a center turn lane. In between, there is approximately one hour where no traffic is allowed. While the idea is very simple, the term suicide lane became a common slang description for this design, because many people ignored their driving or the lights. Because of their history of numerous accidents and collisions, reversible lanes are rarely used now. However, there are some functional examples on the river bridges just east of downtown Los Angeles and in downtown Edmonton which use lights only and nothing else to indicate the direction of traffic for each lane. One famous example is Fall Creek Parkway in Indianapolis, adjacent to the Indiana State Fairgrounds, where out-of-town visitors (typically visiting the state fair) often become disoriented, creating traffic snarls. Some places, like Hawaii, call these lanes contraflow lanes and enforce them with portable barriers or plastic poles that are manually rearranged by work crews before and after rush hour.

*A tram lane is a lane reserved for the use of buses, trams and taxicabs. It is usually encountered in cities with curbside tram network, such as Zagreb.

*A truck lane (United States) or crawler lane (Great Britain) is a lane provided on long and steep uphill stretches of high-speed roads to enhance the ability of vehicles which can maintain speed up the incline to pass those vehicles (usually heavy trucks) which cannot. In addition, these lanes are intended to optimize pavement performance and minimize pavement fatigue. The lane is marked only on the uphill stretch and usually a short distance afterward (for regaining speed). A truckway often allows longer box length; for instance, the Florida Turnpike allows 29.3 meter double trailer combinations, in contrast to normal Florida highways' 16.2 meter limit. Since the major cost of trucking is the fixed cost of the same trailer with its driver the cost per ton of operating with truckway size and weight allowances is 35 to 40 percent below the cost of operations on the non-truckways. [cite book|title=Street Smart: Competition, Entrepreneurship and the Future of Roads|chapter=The Way Forward to the Private Provision of Public Roads|author=Samuel, Peter|pages=516-517]

*An operational lane or auxiliary lane is an extra lane on the entire length of highway between interchanges, giving drivers more time to merge in or out. The lane is created when an entrance ramp meets the highway, and drops out (with an "exit only" sign) to become the ramp at the next exit. [ [ Kurumi's Field Guide to Interchanges - Glossary ] ]

*An overtaking lane is the lane furthest from the shoulder of a multi-lane carriageway (sometimes called the fast lane, although this is deprecated by the authorities).

*The slow lane is the lane nearest to the shoulder of a multi-lane carriageway. This usage leads to the phrase "Life in the Slow Lane", used as the title of various books and songs.

*A driving lane is an area in a parking lot in between parking spaces so that vehicles can drive into and out of the spaces.

Lane markings

Painted lane markings vary widely from country to country. In the United States, Canada and Norway, yellow lines separate traffic going opposite directions and white separates lanes of traffic traveling the same direction, but this is not the case in many European countries.

Medians or central reservations

Besides a painted line, lanes of traffic moving in opposing directions can also be separated by any of the following:

* grass strip or ditch
* a central turning lane that allows vehicles to turn into driveways or streets on the opposite side of the road without stopping traffic
* a wide paved area with special paint markings indicating that it should never be crossed
* metal guard rail (or guide rail) affixed to metal or wooden posts
* cable barriers
* concrete barriers, such as Jersey barriers

Such separations between opposing traffic are referred to as a median in American English and as a central reservation in British English.

Numbering of freeway lanes in California

Traffic reports in California often refer to accidents being "in the number X lane." The California Department of Transportation (Caltrans) assigns the numbers from left to right [] . The fast lane is the number 1 lane. The number of the slow lane (closest to freeway onramps/offramps) depends on the total number of lanes, and could be anywhere from 2 to 6.


For much of human history, roads did not need lane markings because most people walked or rode horses at relatively slow speeds. Another reason for not using lane markings is that they are expensive to maintain.

When automobiles, trucks, and buses came into widespread use during the first two decades of the 20th century, head-on collisions became more common.

Without the guidance provided by lane markings, drivers in the early days often erred in favor of keeping closer to the middle of the road, rather than risk going off-road into ditches or treesFact|date=February 2007. This practice often left inadequate room for opposing traffic.

There are two people who have been credited with the invention of lane markings. In 1911, Edward N. Hines, the chairman of the Road Commission of Wayne County, Michigan was trying to make roads safer. He supposedly came up with the idea of painting stripes to separate lanes of traffic after riding behind a milk truck that leaked milk onto the center of the road, leaving a stripe.

June McCarroll, a physician in Indio California started experimenting with painting lines on roads in 1917 after she was run off of a highway by a truck driver. In November 1924, after years of lobbying by Dr. McCarroll and her allies, California officially adopted a policy of painting lines on its highways. A portion of Interstate 10 near Indio has been named the Dr. June McCarroll Memorial Freeway in her honor.

By 1939, lane markings had become so popular that they were officially standardized throughout the United States, and they were soon copied worldwide.
