In the 18th and 19th centuries, map makers recorded Gaelic placenames in Anglicised versions. One would expect important towns like Stornoway or Portree to have slightly different names in different languages, but it is unusual for this to be the case with small hamlets or minor topographical features, and the Anglicisation of placenames was resented by educated Gaels.
In the 20th century, Inverness County Council, which until the latter part of the century was known for its antipathy towards the Gaelic language, was responsible for erecting road signs throughout the Highlands. The council insisted that these be entirely in English and follow the spellings on the Ordnance Survey maps. Gaelic language organisations had limited resources and thus did not see opposition to this policy as a priority. In September 1970 Aird District Council rejected a proposal for bilingual signs.
In 1973, however, the issue was forced onto the public agenda as a result of the Skye road sign controversy. The council was planning to build a new road south from Portree, and needed to purchase a strip of land belonging to landowner Iain Noble. Noble offered to donate the land to the council on condition that the three signs which were to be erected on the stretch of road be bilingual, a way of registering Gaelic on the linguistic landscape. The proposal was fiercely resisted by the council, and in particular by Lord Burton, Chairman of the Roads Committee, who later the same year attempted unsuccessfully to introduce legislation in the House of Lords limiting the use of Gaelic by Scottish local authorities. However, Noble was supported by a petition signed by many prominent Skye residents, and the experience of Wales, where bilingual signposting had already been accepted, was favourable. As the issue had aroused public interest, and a compulsory purchase order might have been slow and expensive, the council negotiated a compromise: Portree and Broadford both received bilingual signposts on an "experimental" basis.
As Noble had hoped, and the council feared, this set a precedent, which was gradually followed throughout the 1980s, becoming generally accepted in the 1990s. Bilingual signposting is now the norm throughout the Western Isles (indeed for a time directional signposts there were monolingually Gaelic) and also in large parts of the mainland on local authority roads.
In 2001, the Scottish Government announced plans to erect bilingual signage along many of the trunk roads in the Scottish Highlands, in addition to those already erected on local-authority-maintained roads. This project is now all but completed, although importantly it excludes the main A9 trunk road and also the A96 between Inverness and Aberdeen. It has however included the A82 westerly trunk route from Inverness to Glasgow. Since the government has a strict policy of only erecting bilingual roadsigns when new signs in any case had to be erected, the costs to the public purse of making these bilingual has been negligible.
In March 2009, Highland Council's Gaelic committee wrote to the Transport Minister, Stewart Stevenson, asking for the use of Gaelic signage to be extended on trunk roads. The Minister responded by saying that he awaited a review that had been commissioned, as he thought there was some anecdotal evidence of motorists encountering some difficulties with bilingual signage.
A report was published in 2012 by Transport Scotland stating that bilingual signs were not a danger to motorists. It was noted that the signs required slightly more attention on the part of motorists but that it did not pose any real risk. According to the study there has been no detectable change in accident rates.
The report suggests that while there is reasonable evidence to infer bilingual signs increase the demand of the driving task, drivers appear able to absorb this extra demand, or negate it by slowing down, which ultimately results in no detectable change in accident rates.— Consultant, TRL, 
Research conducted by Leeds University indicates that multi-lingual signs consisting of four or more lines of text can cause drivers to brake to allow them time to process the additional information. Following drivers may not react appropriately to the change in speed of the leading vehicle. The study recommends the use of "separation techniques", such as using a different colour of font for each language, which eliminates the problem. Bilingual road signs in Scotland typically use white letters for English and yellow for Gaelic.
A bilingual sign (or, by extension, a multilingual sign) is the representation on a panel (sign, usually a traffic sign, a safety sign, an informational sign) of texts in more than one language. The use of bilingual signs is usually reserved for situations where there is legally administered bilingualism (in bilingual regions or at national borders) or where there is a relevant tourist or commercial interest (airports, train stations, ports, border checkpoints, tourist attractions, international itineraries, international institutions, etc.). However, more informal uses of bilingual signs are often found on businesses in areas where there is a high degree of bilingualism, such as in areas where large concentrations of immigrants settle.
Bilingual signs are widely used in regions whose native languages do not use the Latin alphabet; such signs generally include transliteration of toponyms and optional translation of complementary texts (often into English). Beyond bilingualism, there is a general tendency toward the substitution of internationally standardized symbols and pictograms for text.Gàidhealtachd
The Gàidhealtachd (Scottish Gaelic pronunciation: [ˈkɛːəl̪ˠt̪əxk] (listen); English: Gaeldom) usually refers to the Highlands and Islands of Scotland and especially the Scottish Gaelic-speaking culture of the area. The corresponding Irish word Gaeltacht refers strictly to Irish-speaking areas.
The term is also used to apply to the Scottish Gaelic-speaking Canadian areas of Nova Scotia and Glengarry County, Ontario.
"The Gàidhealtachd" is not interchangeable with "Scottish Highlands" as it refers to the language and not to the geography. Also, many parts of the highlands no longer have substantial Gaelic-speaking populations, and some parts of what is now thought of as the Highlands have long been Scots-speaking or English-speaking areas: Caithness, Cromarty, Grantown-on-Spey, Campbeltown, etc. Conversely, several Gaelic-speaking communities lie outwith the Highland, Argyll and Bute and Outer Hebrides council areas, for example Isle of Arran and parts of Perth and Kinross, not to mention Nova Scotia, North Carolina, and other areas to which there was significant migration. Gàidhealtachd also increasingly refers to any region where Scottish Gaelic is spoken as a first language by much of the population.Galldachd (Gall-dom, Gall referring to a non-Gael) is often used for the Lowlands, although it is also notable that the Hebrides are known as Innse Gall due to the historical presence of Norsemen.Iain Noble
Sir Iain Andrew Noble, 3rd Baronet of Ardkinglas and Eilean Iarmain (8 September 1935 – 25 December 2010) was a businessman, landowner on the Isle of Skye and a noted Scottish Gaelic language activist.Languages of the United Kingdom
English, in various dialects, is the most widely spoken language of the United Kingdom, however there are a number of regional languages also spoken. There are 14 indigenous languages used across the British Isles: 5 Celtic, 3 Germanic, 3 Romance, and 3 sign languages. There are also many immigrant languages spoken in the British Isles, mainly within inner city areas; these languages are mainly from South Asia and Eastern Europe.
The de facto official language of the United Kingdom is English, which is spoken by approximately 59.8 million residents, or 98% of the population, over the age of three. In 2019, some three quarters of a million people spoke little or no English. An estimated 700,000 people speak Welsh in the UK, an official language in Wales and the only de jure official language in any part of the UK. Approximately 1.5 million people in the UK speak Scots—although there is debate as to whether this is a distinct language, or a variety of English.Road signs in the United Kingdom
Road signs used in the United Kingdom conform broadly to European norms, though a number of signs are unique and direction signs omit European route numbers.
There is a vast range of signs in use on British roads, from directional sign posts, to signs warning of possible hazards ahead, and regulatory signs instructing motorists to perform certain actions.Scottish Gaelic
Scottish Gaelic (Gàidhlig [ˈkaːlɪkʲ] (listen)) or Scots Gaelic, sometimes also referred to simply as Gaelic, is a Goidelic language of the Celtic and Indo-European language family, native to the Gaels of Scotland. As a Goidelic language, Scottish Gaelic, like Modern Irish and Manx, developed out of Middle Irish. It became a distinct spoken language sometime in the 13th century, although a common literary language was shared by Gaels in both Ireland and Scotland down to the 16th century. Most of modern Scotland was once Gaelic-speaking, as evidenced especially by Gaelic-language placenames.
In the 2011 census of Scotland, 57,375 people (1.1% of the Scottish population aged over three years old) reported as able to speak Gaelic, 1,275 fewer than in 2001. The highest percentages of Gaelic speakers were in the Outer Hebrides. Nevertheless, there are revival efforts, and the number of speakers of the language under age 20 did not decrease between the 2001 and 2011 censuses. Outside Scotland, a dialect known as Canadian Gaelic has been spoken in eastern Canada since the 18th century. Nearly 4,000 Canadian residents today claim knowledge of Scottish Gaelic.Scottish Gaelic is not an official language of either the European Union or the United Kingdom. However, it is classed as an indigenous language under the European Charter for Regional or Minority Languages, which the British government has ratified, and the Gaelic Language (Scotland) Act 2005 established a language-development body, Bòrd na Gàidhlig.
