It shows cars parked behind it.]] [[Image:Espejo triple Irizar Eurorider 38.jpg|thumb|right|Triple mirror in a Irizar Eurorider bus]] A '''rear-view mirror''' (or sometimes, '''rear-vision mirror''' in British English) is a functional type of [[mirror]] found on [[automobile]]s and other vehicles, designed to allow the driver to see the area behind the vehicle through the back window. Rear-view mirrors are sometimes confused with [[side-view mirrors]], a different type of mirror found on the left- and right-hand sides of most modern vehicles. Though these mirrors do face backwards, they are meant to show the driver the traffic to the left- and right-hand sides of the automobile. Inside rear-view mirrors (and driver-side side-view mirrors) are specifically mandated by legislation to have "unit magnification" and thus are not convex[http://www.fmcsa.dot.gov/rules-regulations/administration/fmcsr/571.111.htm]. The driver is close enough to both these mirrors for simple head motion to be sufficient significantly to expand the field of view. The passenger side side-view mirror is far enough away for the field of view to be fixed, despite movement of the driver and a convex mirror is desirable to expand the field of view. Typically, the rear-view mirror is affixed to the top of the [[windscreen]] on a [[swivel]] [[mount]] allowing it to be freely rotated. Certain car models have the rear-view mirror mounted on top of the [[dashboard]]. When adjusting the mirror, it is advised to sit in the driver's seat in the same manner that you will be sitting while driving. Their utility may be diminished in cars with large [[spoiler (automotive)|spoiler]]s or tiny back windows, obstructions in the back seat or trailer. Vanity mirrors attached to sun visors do not meet the adjustment requirements of rear-view mirrors and cannot be used as such. Inside rear-view mirrors are designed to break away upon collision to minimize injury to occupants who are thrown against it. == History == [[Image:MarmonWasp.JPG|thumb|left|200px|[[Ray Harroun]]'s [[Marmon]] "Wasp" with its rear-view mirror mounted on struts above the car on display in the [[Indianapolis Motor Speedway]] Hall of Fame Museum.]] Although many people imagine the rear-view mirror was designed for safety, in fact its origins are much more varied. The earliest known use and mention of a rear view mirror is by [[Dorothy Levitt]] in her 1906 book ''The Woman and the Car'' which noted that women should "carry a little hand-mirror in a convenient place when driving" so they may "hold the mirror aloft from time to time in order to see behind while driving in traffic" therefore inventing the rear view mirror before it was introduced by manufacturers in 1914. <ref>{{web cite|url=http://en.volvocars.ae/footer/about/NewsEvents/News/news.htm?item=%7BE70B9AD7-1561-4D4D-9951-B79BDEEE28A1%7D|title=All female team create award-winning concept car|publisher=[[Volvo]]|accessdate=2006-12-14}}</ref> The earliest known semblance of a rear-view mirror mounted on a motor vehicle appeared in [[Ray Harroun]]'s [[Marmon]] racecar at the inaugural [[Indianapolis 500]] race in [[1911]]. According to Al Binder of ''Ward's Auto World'': :''As per the custom of the day, all cars except Harroun's carried riding mechanics who, among other things, helped the driver keep track of other vehicles during the race. Unable to find a mechanic to ride with him, Harroun installed a mirror on his car so he could view what was happening behind him and be alert to any cars overtaking him. Automotive historians credit this as the first use of a rear view mirror on an automobile.''[http://waw.wardsauto.com/ar/auto_rearview_mirror/] Although Harroun's use is the first known use of such a mirror on a motor vehicle, Harroun himself claimed he got the idea from seeing a mirror used for the same purpose on a horse-drawn vehicle in 1904. <ref>[[Donald Davidson (historian)|Davidson, Donald]]. (2006). ''The Talk of Gasoline Alley'' [radio program]. [[WIBC]], [[May 28]], [[2006]].</ref> The invention seems to have worked—Harroun won the race, netting a [[United States dollar|US$]]14,250 prize, equivalent to about US$270,000 in 2003 [[dollar]]s. However, the rear-view mirror had to wait for [[Elmer Berger]], the man usually credited with inventing the rear-view mirror, to first develop them for street use. == Augmentations and alternatives == Recently, [[Backup camera|rear-view video cameras]] have been built into many new model cars, such as the [[Mazda Hakaze Concept]]. This was partially in response to the rear-view mirrors' inability to show the road directly behind the car, due to the rear deck or trunk obscuring as much as 3–5 [[metre]]s (10–15 [[foot (unit of length)|feet]]) of road behind the car. For example, as many as 50 times a year, small children are killed by [[SUV]]s in America because the driver cannot see them in their rear-view mirrors [http://www.cbsnews.com/stories/2002/10/22/earlyshow/living/parenting/main526462.shtml]. These camera systems are usually mounted to the bumper or lower parts of the car allowing for better rear visibility. In addition, rear-facing [[sonar]] arrays and back up beepers help avoid accidents while reversing. [[Aftermarket (automotive)|Aftermarket]] secondary rear-view mirrors are available. They attach to the main rear-view mirror and are independently adjustable to view the back-seat. This is useful to parents to monitor their children in the backseat. Aftermarket mirrors can be attached as extensions to the door mirrors, that allow a driver to see behind when towing a [[Travel trailer|caravan]]. A similar device can be fitted to the rear of a van or SUV, to allow viewing down behind the vehicle, for close parking. == Dimming == A traditional rear-view mirror can be [[wikt:tilted|tilted]] to reduce the brightness and [[Glare (vision)|glare]] of lights, mostly for [[headlight]]s shining directly on the eye level at night. This manual tilt mirror is made of a piece of glass that is wedge-shaped in cross section—its front side and back (silvered) side are not parallel, unlike normal mirror glass. In the default day view, the front side is tilted and the back side (which has a reflective coating, usually with silver like a mirror) is head-on and will give a strong reflection. When the mirror is tilted, its front side is head-on and the back is tilted. This view is actually a reflection off the clear, front piece of the glass rather than the back silver-coated part. Since the front part allows most of the light to go through, only a small amount of light is now reflected into the driver's eyes. Some rear-view mirrors have electronic auto-dimming features built in (mirrors with automatic anti-glare function) while others are adjustable so that a lower light level setting may be used. Because of this it is advisable to set the darker setting to be aimed lower in the car than the lighter setting. This is mostly because at night when you readjust the mirror to use the darker setting the lighter angles will be pointed to the lower contrast roof of the vehicle instead of the higher contrast areas such as the backs of the seats. == Bicycles == Some [[bicycles]] have rearview mirrors. However, [[motorcycle]]s carry that feature more frequently than pedal bikes. == In art == In modern [[art]], particularly music and [[poetry]], the rear-view mirror has become a common [[metaphor]] for reflecting upon the past, whether upon one's own memories or a time even more distant. For example, Jane Sequoya's "Scene Through the Rear-View Mirror" expresses a woman's regret for a lost love partly by comparison with the lost [[Native Americans in the United States|Native American]] people of the prairies [http://www.colorado.edu/journals/standards/V5N1/poetry/Sequoya.html]. In popular music, artists ranging from [[Alicia Keys]] to [[Meat Loaf]] to the [[Starland Vocal Band]] as well as [[Pearl Jam]] have written songs with "Rear View Mirror" in the title. The metaphor is particularly prominent in [[country music]], where it is featured in hits such as [[Jo Dee Messina]]'s "[[Bye, Bye]]", [[Chely Wright]]'s "[[Shut Up and Drive (Chely Wright song)|Shut Up and Drive]]", [[Doug Supernaw]]'s "She Never Looks Back", and [[Julie Roberts]]' "Break Down Here". Also another song it is used in is [[Tupac Shakur]]'s "Starin' Through My Rearview", featured in the film ''[[Gang Related]]''. == See also == {{Wiktionary}} *[[Blind spot (automobile)]] * [[driver visibility]] ==References== <div class="references-small"><references/></div> {{CarDesign nav}} [[Category:Auto parts]] [[Category:Automotive accessories]] [[Category:Mirrors]] [[de:Rückspiegel]] [[fr:Rétroviseur]] [[ja:ドアミラー]] [[sv:Backspegel]]
