Road signs in the Republic of Ireland do not differ greatly from those used elsewhere in Europe – with the notable exception that hazard or warning signs follow the "New World" style of a yellow diamond. The symbols used on these warning signs do, nevertheless, resemble much more closely those used (on red-bordered white or yellow triangles) in the rest of Europe than many of those seen in the United States.

Regulatory signs (relating to limits and prohibitions) differ very little from those used in the rest of Europe.

The system of directional signs is based upon, and is very similar to, that employed in the United Kingdom, but is bilingual everywhere except in the Gaeltacht, where only the Irish language is used on signs.

[edit]

Only regulatory signs and certain road markings are prescribed in law under the Road Traffic (Signs) Regulations 2024.[1] All other signs are not legally prescribed, but are instead defined in the Traffic Signs Manual (TSM) issued by the Department of Transport, with the latest edition published in 2019 (along with some chapters updated in 2021 and 2024).[2] This succeeded two earlier editions — Traffic Signs Manual 2010[3] and Traffic Signs Manual 1996.[4] Regulatory signs and road markings are also defined in the TSM, but the regulations for them take precedence — the TSM simply provides guidance regarding the design and installation of signs and is not by itself a law. It bears much similarity to the United Kingdom Traffic Signs Manual.

History

[edit]

Directional information signs

[edit]

Advance directional sign used pre-1975. This sign has since been removed.

The former 'fingerpost' style of Irish directional signs can still be seen in many rural areas of 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 placename in Irish was on top and in a smaller font than the one in English). Sometimes, the former route number ("T" for trunk road, "L" for link road) can be seen, and the former Bord Fáilte logo can be seen on some (they had responsibility for signs for a time), as well as occasionally a harp. Distances on these signs are in miles.

This style of sign 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 sign style being introduced in 1977, the design change was never legislated for (apart from a reference to the change to italics in 1989) and the old designs were repealed only under the 1997 regulations, 20 years later.

The first generation of the current sign 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 signs since then.

"Compass-point directions" (such as "The North, "The South" and "The West") were formerly used, particularly in Dublin where the road network intersects. This system, inherited from the UK system,[citation needed] was permitted in the 1996 TSM but subsequently prohibited in the 2010 TSM, which mandated the use of the terminal destination and next primary destination of the route instead. Today there remain very few examples, one notably on George's Quay.

Motorway / high quality dual carriageway signs

[edit]
Original design
[edit]

The original design (1983–1989) of Irish motorway signs were a simpler version of the UK design.[citation needed] 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, signs on motorways were nearly identical to that on UK motorways[citation needed] (but see new motorway signs, below); although in 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.

2005-2007
[edit]

In 2005, upon the opening of the South Eastern Motorway section of the M50, the National Roads Authority erected new style gantry signs. The new signs retained typical colours and fonts but differed from older side of road signs in that they 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 signs were also erected on the N2 FinglasAshbourne scheme and N7 ClondalkinNaas scheme. These were the first roads in Ireland where overhead gantry signs have 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 signs are visually clearer than older type signs with drivers able to read the gantry signs from a distance of approximately 300 m on a straight stretch of road. Despite their significant advantages, the new gantry signs 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.

Current signing policy
[edit]

In July 2007, some of the gantry signs on the M50 between Junctions 13–17 erected in 2005 were replaced with signs 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.

Regulatory signs

[edit]

Some rare speed limits are still in mph after 2005. They now read m.p.h. to distinguish them from the metric standard.

Until 1997, all mandatory signs were circular in shape and featured black symbols on a white background with a red border. A unique example was the "keep left" sign, which used a curved arrow pointing upwards. Since the introduction of the 1997 regulations, their design is identical to those used in the United Kingdom, with white symbols on a blue background.

The former "No Entry" sign, a prohibition 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.

Ireland's 'Yield' sign formerly read 'Yield Right of Way' from 1962 until 1997, and many of this older variant can still be seen around the State. Prior to 1962, it did not feature any inscription.

On 20 January 2005, imperial speed limits on signs were replaced with metric speed limits. Around 35,000 existing signs were modified or replaced and a further 23,000 new signs were erected bearing the speed limit in kilometres per hour. To avoid confusion with the old signs, all speed limit signs include the symbol "km/h" beneath the numerals.[7] Distances, such as those shown on route confirmatory signs, had already been displayed in kilometres since the 1970s. Due to the two speed limits possible on non-urban roads after 2005 metrication, the "end of speed limit" signs in Ireland (a white circle with black diagonal line as used in the UK) is no longer used – the end of an urban speed restriction is signalled by the sign displaying the limit for the following section.

In October 2022, a nine-month long pilot scheme was undertaken by the NRA to introduce new signs that would replace Belisha beacons on newly installed pedestrian crossings. This scheme saw the introduction of a new blue square-shaped pedestrian crossing sign[8] (which may also feature a fluorescent yellow background), like those already used in continental Europe. Following the conclusion of the study, the sign was officially adopted in March 2024, though beacons are still permitted to be installed.

Warning signs

[edit]

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.[9] 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 yellow. 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.

Typeface

[edit]

The Transport and Motorway typefaces are used on Irish road signs. Although it was designed uniquely for dark text on light backgrounds, the Transport Heavy weight is used for all signs in Ireland. A distinctive oblique variant of Transport Heavy is used for Irish text, in which letters are inclined at 15 degrees. The letter a is represented by script a (ɑ), and the letter i was represented by dotless i (ı) in order to better differentiate them from their accented forms; however, the normal letter i is now always used. Additionally, the capitals M, N and A are similar in appearance to lowercase m, n and a.

The Irish text is placed above the corresponding English and is always in mixed case. All English text is in upper case Roman alphabet.

Colour

[edit]

Motorway signs use white text on a blue background. National routes (both primary and secondary) use white text on a green background, with the specific route number in yellow 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 (derived from the Guildford Rules) is used to show roads of different classification on signs.

Types of sign available

[edit]

A number of types of sign are available for use on all purpose roads. Chapter 2 of the TSM divides directional information signs into six categories:

  1. Stack Type Advance Direction Signs — destinations are signposted in advance of at-grade roads, such as T junctions and staggered crossroads, where the destinations are placed on separate panels.
  2. Map Type Advance Direction Signs — destinations are signposted in advance of grade separated interchanges and roundabouts, where the junction is displayed as a pictogram. These are sometimes used at at-grade roads in exceptional circumstances.
  3. Direction Signs / Flag Signs — these are located at the road junction itself. The sign has a triangular point at one end and a chevron, and can also appear in the form of a fingerpost, particularly on rural roads.
  4. Overhead Gantry and Exit Taper Gantry Signs — destinations are signposted in advance on signs mounted on gantry structures.
  5. Route Confirmatory, Route Marker and Route Direction Signs — these provide confirmation and information to drivers about the destinations and route ahead.
  6. Other directional information signs, such as Next Exit Signs (which provide a list of destinations to take at the next exit) and Lane Destination Signs.

However, on rural roads, it is common for the appropriate signs to be missing. Often junctions are signed with only a fingerpost.

Destination signing policy

[edit]

Generally directional signs on major routes show major or end destinations. Smaller towns and placenames are shown only on signs nearer to that location. 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 practice of signposting 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.

Destinations on motorways and high-quality dual carriageways are signposted as follows:

  • 2 km – Next Exit Sign, listing destinations to be reached by this exit
  • 1 km – Advance Directional Sign (map type or gantry)
  • 500 m – Advance Directional Sign (map type or gantry)
  • Beginning of exit taper (deceleration lane) – Exit Taper Gantry Sign
  • Gore – Exit Sign with junction number
  • 500 m following exit – Route Confirmatory Sign

Other information signs

[edit]

Chapter 4 of the TSM divides other information signs into the following categories:

  • Signs displaying civic or geographical information
  • Signs indicating facilities ahead of interest to road users
  • Signs indicating traffic calming measures
  • Signs indicating particular road layouts
  • Signs indicating alternative or diversionary routes
  • Services Signs
  • Toll Road Signs
  • Tunnel Information Signs
  • Miscellaneous Signs
  • Tourist Attraction Signs
  • Cycle Route Signs
  • Regulatory signs

    [edit]

    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. These signs are laid out in Chapter 5 of the TSM.

    Speed limit signs have the speed with the letters "km/h" underneath.

    Warning signs

    [edit]

    Warning signs use the MUTCD design, in that they are black on an amber (orangish-yellow) background, and are diamond-shaped. This type of road sign was introduced with the Traffic Signs Regulations, 1956.[10] Some signs were added later, and many types of signs, even common ones, do not appear in any statutes. These signs are laid out in Chapter 6 of the TSM.

    Some types of sign (for example, pedestrian/zebra crossing signs) are somewhat randomly designed, and differ between county/city boroughs.

    Roadwork signs

    [edit]

    Road works hazard signs are reddish orange. Lane closure signs are diamond shaped for Level 1 roads (Urban and Low Speed Roads) and Level 2 roads (Rural Single Carriageway Roads), and square shaped for Level 3 Roads (Dual Carriageways and Motorways).

    Supplementary plates

    [edit]

    Supplementary plates are used in addition to warning, regulatory and roadworks signs. Their purpose is to provide additional information to the sign they are placed beneath (with sign P 056 being an exception, which is placed on its own as it contains a regulatory sign).

    Notes

    [edit]
    1. ^ Must always be accompanied with supplementary plate P 041
    2. ^ The diagonal bars are reversed if the sign is placed on the other side of the carriageway.
    3. ^ a b Text for this sign is variable. Permitted variants are outlined in the TSM.
    4. ^ At the end of the restriction, "Ceantar/ZONE" is substituted with "Críoch/END".
