Road signs in Ireland mostly differ from the traffic signs used elsewhere in Europe. Directional signage is similar to that of the United Kingdom, but is bilingual. Distances are in kilometres. Apart from directional signage, the basic prohibitory signs such as "no left turn" and "no right turn" are among the few standard signs used in Ireland. The most widespread signage, hazard or warning signs, employs the yellow diamond layout used in the United States, Canada, Australia and elsewhere, but nowhere else in Europe. The actual symbols used on these warning signs, however, often bear a closer resemblance to those used in the rest of Europe than to those seen in the US. On 20 January 2005, Ireland fully adopted metric speed limits.[1] Around 35,000 existing signs were replaced and a further 23,000 new signs erected bearing the speed limit in kilometres per hour. To avoid confusion with the old signs, each speed limit sign now has "km/h" beneath the numerals.
Irish signs depict classical silhouetted persons.

Signage in Ireland is prescribed under the Traffic Signs Manual 2010 (TSM), issued by the Department of Transport.[2] Published in late 2010 after a long period of review, this replaced at least one older edition, the Traffic Signs Manual 1996.
Older signs appear in secondary legislation (see the references section at the bottom), however much of the signage (particularly directional signage) used has never been legally prescribed for. The TSM itself is not a law. However, signage is meant to be based on the principles in it. It is partially based (particularly directional signage) on the United Kingdom Traffic Signs Manual,[3] itself based on the Traffic Signs Regulations and General Directions.
Those road signs which are prescribed in law are prescribed under the Road Traffic (Signs) Regulations 1997-2004, the 1997 regulations being the main set [4] which repealed various traffic signs regulations dating back to 1964.
Directional signage is fairly similar to the United Kingdom design. Place names are listed in Irish in mixed case, followed underneath by the English language equivalent place name in all capital letters. The Transport Heavy and Motorway typefaces are used, although the Irish language text uses a distinctive oblique variant, in which letters a are represented by script a (ɑ), and letters i are represented by dotless i (ı) in order to better differentiate from their accented form. Only the Irish place name is shown if the sign is in the Gaeltacht, or the official name in English is identical to the Irish name or nearly so (for example Dún Laoghaire or Port Laoise). Due to the need to signpost in both languages, usually a limited number of destinations will be signposted. If a destination can be reached by following a route which is a spur from that route, the destination and route number will be shown in brackets. Also, distances are shown in kilometres.
Motorway signs use white text on a blue background. Non-motorway national primary routes use white text on a green background, with the specific route number in yellow bold text. Regional and local county roads use black text on white background. Signs to points of interest (services, institutions, tourist sights) have white text on a brown background. Patching (according to the Guildford Rules) is used to show roads of different classification on signs. On all purpose roads, signs for roads whose only destination is a motorway should display the motorway symbol.
A number of types of sign are available for use on all purpose roads. A properly signed junction will be signed in advance by advance directional signs, which can either be map type (which displays the junction as a pictogram) or stack type, in which the destinations are on separate panels. In Ireland, NRA policy encourages stack type signs at normal intersections (such as T-junctions or crossroads), with map-type signs used mainly for roundabouts and for grade-separated junctions. However map-type signs are occasionally used at normal intersections where it is necessary to sign a restriction (such as a weight or height restriction). At the junction itself, either a flag sign - a sign with a triangular point at one end and a chevron - or (on rural roads) a fingerpost points the driver in the direction to be taken. After the junction, a route confirmation sign listing the route number and the primary destinations will be erected.
However, on rural roads, it is common for some or all of the above signage to be missing. Often junctions are signed with only a fingerpost.
One feature of road signage in Ireland, particularly along Dublin's quays, is that some national primary road signage directs drivers generically to destinations such as "The West" and "The South" and "The North". This system, inherited from the UK system, was banned under the 1996 TSM, which mandates the use of the terminal destination and next primary destination of the route instead, but signage was patched with specific destinations only in the early 2000s. While this has been replaced with specific placenames in some cases, it remains in use in other areas. In summer 2006, signage for "North" and "South" was erected in Ashbourne at the start of the new N2 dual carriageway. Nevertheless, generally directional signage on major routes shows major or end destinations. Smaller towns and placenames are shown only on signage nearer to that location. Thus, travelling on the Irish route network requires some geographical knowledge of the country.
The original design (1983–1989) of Irish motorway signage was a simpler version of the UK design. These signs were only ever in use on the M7 Naas Bypass and M1 Airport Motorway and only rare examples are still in situ.
From 1989-2005, signage on motorways was nearly identical to that on UK motorways (but see new motorway signage, below); although in the Ireland, motorway junctions were not always numbered, or the number was not always signposted. The sign at the actual exit, which in the UK shows the road number to be reached, was replaced by a flag sign with the destination instead. On the M50, in the case of junctions with national routes, the initial advance direction sign was replaced with a list of destinations for that national route. The 1989 design of signs can still be seen on older sections of the M4 and M7.
In 2005, upon the opening of the South Eastern Motorway section of the M50, the National Roads Authority erected new style gantry signage. The new signage retained typical colours and fonts buts differed from older side of road signage in that it used separate overhead panels for each lane, headed with the route number in each case as well as new half-gantry signs closer to the exit. The new signage was also erected on the N2 Finglas – Ashbourne scheme and N7 Clondalkin – Naas scheme. These were the first roads in Ireland where overhead gantry signage has been used as a matter of course, instead of just very major junctions. Drivers are given clear advanced warning 1 km ahead of an upcoming junction. A half gantry at the junction then directed them to their destination. The new style signage is visually clearer than older type signage with drivers able to read the gantry signage from a distance of approximately 300m on a straight stretch of road. Despite its significant advantages, the new gantry signage caused confusion because the downward arrows over the left traffic lanes seemed to indicate to drivers that they should pull out into the right lane if they wish to continue on the motorway or dual carriageway, breaking the keep left rule.
In July 2007, some of the gantry signage on the M50 between Junctions 13–17 erected in 2005 was replaced with signage in a revised style, reverting to a single panel over the mainline. By March 2008 all the 2005 style gantries had been removed from the M50 (and were later removed from the N2 and N7). The one aspect of the 2005 scheme that was retained is the half-gantry (or cantilever) sign just before the exit, which has now also been extended to other roads. A second change introduced in 2007 is that the flag sign at the gore, which previously listed the primary destinations to be reached, now features the junction number and the word "Exit" instead. This revised scheme has been used on most motorway and high quality dual carriageway schemes since 2007. The "Next Exit" signs listing destinations, which were originally used only on the M50, are now extended to other motorways.
Thus the sequence of signage at a motorway junction in Ireland on motorways opened since 2007 (and older motorways which have been re-signed) is as follows:
- "Next Exit" sign at 2 km listing primary destinations to be reached by this exit. - 1 km - Advance directional sign (map type) or gantry in lieu - 500m - Advance directional sign (map type) or gantry in lieu - 100m - Cantilever sign - Gore - "Exit" sign with junction number - 500m following exit - route confirmation sign.
To this day the Ireland continues to use the "Motorway Ahead" sign, listing the motorway regulations.
This new signage has now been formally adopted with the publication of the 2010 TSM.
Warning signs are similar to the United States design, in that they are black on an amber (orangish yellow) background, and are diamond shaped. Road works hazard signs are reddish orange. This type of road sign was introduced in 1956 with the Traffic Signs Regulations, 1956. Some signs were added later, and many types of signs, even common ones, do not appear in any statutes. Some types of sign in particular (for example, pedestrian/zebra crossing signage) are somewhat randomly designed, and differ between county/city boroughs.
The "low bridge" sign was the last road sign with an imperial measurement allowed to be erected in Ireland, and was only replaced with a metric only version with the publication of the 2010 TSM. Most examples of this sign in situ are still the dual imperial/metric version, with the imperial only version still in situ is some locations.

Regulatory signs are mostly circular and mostly black on a white background, with a red border. If the sign contains a prohibition, a red line will diagonally bisect the sign. This type of road sign was introduced in 1956 with the Traffic Signs Regulations, 1956. Some signs were added later.
In Ireland, the "Give Way" sign, a downward pointing triangle, reads "Yield" (on signs erected prior to 1997: "Yield Right of Way" ) or, in Gaeltacht areas, "Géill Slí". A blank inverted triangle was provided for in legislation applicable between 1956 and 1961. The international octagonal "Stop" sign is also used.
Speed limit signs have the speed with the letters "km/h" underneath. 120 km/h is used for motorways and high quality dual carriageways e.g. N2, 100 km/h is used for national primary and national secondary roads and also part the R132 in Co.Louth. 80 km/h is used for regional and local roads. 60, 50 and 30 km/h are used in urban built up areas (see Road speed limits in Ireland). There are no longer any "end of speed limit" signs in Ireland (a white circle with black diagonal line as used in the UK). 40 mph signs are still present at the main exit of Shannon Airport.
Although differing from the design originally laid down (see Regulatory Signs below), "Keep Left" and "Keep Right" signs are now mostly white on a blue background, on the British pattern. In order to avail themselves of standard designs from British suppliers, local authorities had made extensive use of the white-on-blue design, mostly because the electronically lit type of white-on-blue was more practical, in consequence of which legislation was enacted making both patterns legal. Under the Irish Power of One (energy conservation campaign) the electronic signs are being gradually replaced by reflective signs. The former "No Entry" sign, a prohibititon sign with an upward pointing arrow, was replaced with the international standard red disk in TSM 2010. However the older version, now termed "No Straight Ahead", may be used when combined with a time or other restriction.
Signage shown in the table below is not relative size in all cases. Images are based on sizes presented in different ages of legislation. Actual signage may be found in varying sizes, with the 1994 regulations finally setting three definitive sets of metric dimensions for each sign. Larger signs are used on motorways, dual-carriageways, major junctions, etc.

The former "fingerpost" style of Irish directional signage can still be seen in many areas of rural Ireland. These signs differ from their modern day equivalent as they have black raised text on a white background. Destinations are in all caps (the Irish letter is simply smaller than the English one). Sometimes, the former route number ("T" for trunk road, "L" for link road) can be seen, and the former Bord Failte logo can be seen on some (they had responsibility for signage for a time), as well as occasionally a harp. Distances on these signs are in miles.
This style of signage has become a common feature of many tourist images of Ireland and can be seen in some Irish pubs. However, they can be easily rotated, and have been done so on occasion and therefore are not completely reliable. While most examples of these signs still in situ are rural finger-posts, the advance directional sign of this era can still very occasionally be seen: this has a grey background, with the destinations in outlined, white-background boxes linked together with black lines, and the text is not raised on these, unlike on fingerposts. These signs, rare even when the system was in use, can be seen in some areas of Dún Laoghaire and Drogheda. These signs were prescribed under various regulations, with the final design prescribed under the Road Traffic Signs (Regulations) 1962.[5]
Despite the new signage style being introduced in 1977, the design change was never legislated (with only a reference to the change to italics in 1989) for and the old signage design was repealed only under the 1997 regulations, 20 years later.
The first generation of the current signage system, introduced in 1977, can also be seen in on some national roads (and also on the oldest stretch of the M1). This is similar to the current system, but the signs are simpler, a different shade of green is used, and the Irish place names are not in italics. These signs were directly based on the Worboys Committee designs which had been adopted in the UK in 1965. These signs were replaced by the current system on 1 January 1989.[6] The design of signs has continued to evolve with the introduction of patching under the Guildford Rules in 1994 and the introduction of cantilever directional signs in 2005, as well as the expansion in gantry signage since then.
The Irish "Yield" sign formerly read "Yield Right of Way", and many of this older variant can still be seen around the country.
Before adoption of the 1956 traffic signs regulations, warning signs accorded to a standard laid out in the 1926 "Road Signs and Traffic Signals Regulations" (see References, below). These signs, unlikely to exist in situ anywhere in Ireland nowadays, were similar to signs used in the United Kingdom at that time.
The signs were cast-iron plates, with raised type painted black on white. A square pictogram illustrated the hazard, and the type of hazard was written in both Irish, with traditional typeface, and English. A hollow red triangle normally surmounted the pole to which the sign was attached.
