A stop sign is a Traffic Sign , usually erected at Road Junction s, that instructs drivers to make a brief and temporary, but complete, stop upon reaching it, and then to proceed only if the way ahead is clear. Stop signs are not generally required at every intersection, but they are often used to control conflicting traffic movements at dangerous intersections which are not busy enough to justify the installation of either Traffic Light s or, especially in Europe, a Roundabout . In the United States and Canada they are commonly used in residential areas, and near places where children play, as a general Traffic Calming measure. In these countries it is not uncommon for stop signs to be erected on all three or four intersecting roads. The intentional removal of stop signs from their posted locations is a crime in most U.S. states. Fatal accidents caused by someone removing a stop sign on purpose could also result in Manslaughter charges against the offender. The purposeful removal of stop signs began in the 1980s as a College prank and, today, one may find illegally obtained stop signs hanging in the occasional college Dorm rooms. Anyone who wishes to legitimately obtain a stop sign for home display can purchase one new from a traffic supply house for about US$ 75. The following remarks concerning the right-of-way rules at intersections with multiple stop signs apply to the United States and Canada:
Stop signs, usually based on the American design, are found all over the world, although in Europe they tend to be used far more sparingly than in North America (with most intersections lacking traffic lights being controlled by Give Way Sign s or equivalent road markings), stop signs generally being restricted (on the principle that "familiarity breeds contempt") to situations where coming to a dead stop is absolutely essential because of poor visibility at the intersection concerned. In all countries, the driver must actually stop at stop signs even if no vehicles or pedestrians are visible. However, some drivers practice the illegal manoeuvre known as a rolling or "California" stop: slowing down significantly but not stopping completely at the sign. Yield Sign s ("Give way" signs in the UK , Australia , and New Zealand ), on the other hand, require the driver only to slow and prepare to stop, but do not require an actual stop if the way ahead is clear. HISTORY Stop signs originated in Detroit, Michigan in 1915. The first had black letters on a white background and were somewhat smaller than the modern one. As they became more widespread, a committee supported by the American Association Of State Highway Officials (AASHO) met in 1922 to standardize them, and it selected the octagonal shape that has been used in the U.S. ever since. The unique eight-sided shape of the sign allows drivers facing the back of the sign to identify that oncoming drivers have a stop sign and prevent confusion with other traffic signs. In 1924, the sign changed to black on yellow, the predominant color until 1954. Another competing group, the National Conference On Street And Highway Safety (NCSHS), simultaneously advocated an even smaller, red-on-yellow stop sign. All of these signs were typically mounted only two or three feet above the ground. These two organizations conflicted but eventually combined into the Joint Committee on Uniform Traffic Control Devices, which in 1935 published the famous '' Manual On Uniform Traffic Control Devices for Streets and Highways'' (MUTCD) detailing the stop sign's appearance. The MUTCD stop sign was altered eight times between 1935 and 1971, mostly dealing with its reflectorization and its mounting height; the most drastic change came in 1954, when the sign gained its white-on-red color. Red is also the color for ''stop'' on Traffic Signals , unifying red as ''stop'' signal for drivers worldwide. Although already widespread, use of the MUTCD stop sign passed into law in the United States in 1966. The mounting height reached its current level of 2.1 m (7 ft) in 1971. They were later adopted by the European Union as part of their effort to standardize road travel across member countries. SIGN VARIANTS Although English-speaking and European Union countries use the original word "STOP" on stop signs, most countries, and sometimes even smaller political districts, prefer to use a roughly equivalent word in their primary language instead; its appearance is otherwise the same of white text on a red octagon. The few known exceptions include Israel (which uses a solid white hand on a red octagon) and Japan (which uses the local word for ''Stop'' in white type on an inverted solid red triangle). Although the word used isn't universally standardized, some commonly seen examples are: SEE ALSO EXTERNAL LINKS
