Road signs in Ireland

Road signs are the standard means of regulating behaviour on the motorways in Ireland to communicate basic rules and regulations through simple graphics that can be understood easily. In most of the parts, these road signs usually appear generic and similar to those found in other places across Europe and beyond, but it is important to mention that road signs in Ireland may have a few unique differences and exceptions. For example, in Ireland, the “Give Way” sign (a red downward pointing triangle on a white background), will read as “Yield”. In some Irish speaking areas, the same is read as “Geill sli”, printed in Irish Gaeilge.

Road signs in Ireland include regulatory traffic signs (usually red and white), the motorway and mandatory traffic signs indicating traffic (usually white on blue background). There are also the warning signs in yellow and black shaped in diamond that show an upcoming road hazard such as dangerous corners ahead. There are also the manual control signs at roadworks and the warning signs for roadworks which are usually orange in colour. These road signs, especially the information signs, are particularly handy for a tourist who needs guidance and help highlighting places of interest and directional signs that flags the nearest town or region.

Above all, it must be emphatically stated that these Road signs are of high importance on the Ireland Motorways and any failure to its compliance may attract stiff penalties.

Road signs are generally divided into four different aspects. These are Regulatory road signs, Warning road signs, Information road signs and motorway road signs.

Warning signs are given as

Dangerous corner ahead
Roundabout ahead
Mini-roundabout ahead
Merging traffic
Two-way traffic
Dangerous bend ahead
Series of dangerous bends ahead
Series of dangerous corners ahead
Restricted headroom
Warning Road Signs

Dangerous Corner Ahead

It is a right angled pointer and its pointer shows the driver which side, the road is going to make a sharp turn, It shows a very turn in any direction and no matter how much experienced you are, you need to take care of this sign and give more attention and use horn in this case.

Roundabout Ahead

It is a sign showing three arrows making a circle and pointing towards the next arrow showing that there is a big roundabout near you ahead and you should slow down and concentrate on the path carefully.

Mini-Roundabout Ahead

Ireland has a complex road structure and has roundabouts in most of its road junctions. This consists of three arrows making a circle with a small circle in the centre showing a small roundabout ahead. So you need to slow down and pass through it carefully.

Merging traffic

It is a sign showing that the two roads are going to merge ahead and all the traffic is going to pass through a single lane. The signs have two lanes merging at a point to show the merger of traffic.

Two-way traffic

It consists of two arrows pointing in opposite directions to show that the road has two lanes to let traffic go in both the directions divided by a concrete ridge. Also, each lane is further divided into fast and slow lanes. So, you must drive carefully whether the lane is fast and slow and drive accordingly.

Dangerous Bend Ahead

Sometimes this sign is confused with the dangerous corner but as both of them show the dangerous turn ahead. But the dangerous bend shows the presence of a steep curve whereas the dangerous corner shows the turn at right angles. On this road, you need to slow down and give horn to prevent any mishappening if two vehicles are crossing the turn at the same time.

Series of dangerous bends ahead

This is a snake-like looking sign showing there are multiple bends ahead on the road due to tough topography or rough roads. It is generally placed on the hilly areas and areas that pass through forests and other difficult areas.

Series of dangerous corners ahead

This sign contains an arrow with multiple sharp bends showing that the road ahead is going to take multiple sharp turns one after the other within the single lane only. This is to aware the drivers to slow down and look for the turns as it won’t be visible ahead for the upcoming vehicles.

Restricted Head rooms

It is a sort of restriction on the vehicles passing through this road. It shows the signs of allowing only a particular kind of vehicle to pass through as a vehicle with a limited height and width. If your vehicle does not fit in the specifications as given then you will face restrictions ahead.


It shows that the lane you are travelling in is going to enter the new straight lane or the lane is going to merge into a highway which has more traffic. While entering the wider road, you must take care of the other vehicles passing by as the speed of vehicles travelling on this road generally passes with higher speed.

Junction Signs

It shows the sign of merger of roads into wider long roads and presence of more traffic with vehicles of high speed that requires more care.

Junction signs are :

Side road
Staggered crossroads
Junctions Ahead Road Signs

Advanced Warning Signs of Roads

These signs insist to take certain actions ahead and warn regarding some condition so that the driver can take extra care while passing through these junctions.
