Road signs
Learn the system, not just the pictures. Once you know what each shape and colour means you can read a sign you have never seen before — which is exactly what the test is checking. 220 signs can appear on the category D test.
Shape and colour
Amber diamond
Warning — a hazard ahead. Ireland uses a diamond, not the red triangle used across most of Europe and in the UK.
Orange diamond
Warning at roadworks. Deliberately distinct from the permanent amber ones, so a temporary hazard stands out.
Red circle
Prohibition — you must not.
Blue circle
Mandatory — you must.
Octagon
Stop, and nothing else uses this shape.
Inverted triangle
Yield.
Blue rectangle
Information.
Red prohibits, blue compels. Getting that pair straight answers a large share of the sign questions on the test.
Direction signs
The colour tells you what class of road you are being sent onto — and therefore what its default speed limit is.
Blue
Motorway
Green
National roads (N-numbers)
White with black text
Regional and local roads
Brown
Tourist and heritage attractions
10 signs, quick quiz
1 of 10
Each sign as it stands on the road, and four meanings. Pick one — the meaning is what the test asks for, not the picture, and the wrong answers are real signs of the same kind.
What does this sign mean?
End of detour.
You are back on the road the closure took you off.
What does this sign mean?
School children crossing.
Expect children to appear without warning and to misjudge speed and distance.
What does this sign mean?
Maximum gross weight.
Gross weight is the vehicle plus everything in it, not the unladen weight.
What does this sign mean?
Emergency area.
What does this sign mean?
Lay-by-sign.
What does this sign mean?
Right lane closed.
Merge in turn when you reach the closure. The same sign with the bar on the left means the left lane is closed.
What does this sign mean?
Risk of grounding.
Found at humpback bridges and some level crossings. A low trailer can bottom out on the crest and stick there, which is how vehicles end up stranded on a railway line.
What does this sign mean?
Tram speed limit.
One of the Luas signs, aimed at tram drivers rather than at you. It is worth knowing because it marks where the tram line runs alongside the road.
What does this sign mean?
Countdown marker — 200 m.
Two bars. The bars count down as you approach: three, two, one.
The signs are drawn to the Traffic Signs Manual's designs, by us or from public-domain drawings on Wikimedia Commons; none is official artwork.The meanings are the book's; the wording of a question is ours.
In the app
Every sign in your pocket, and three ways to learn them.
Reading a list of signs is not the same as knowing them. The app makes you produce the meaning, which is what the test asks for.
The signs are drawn in the app, not photographed — the same shapes at any size, in the dark.
The whole library, and every sign turns over
Tap a sign for what it means and where you meet it — the meaning is the thing the test asks for, not the picture.
Set out in the groups the Irish sign guides use, and filtered by kind: warning, roadworks, regulatory, information, motorway
Search by name when you have seen one on the road and want it now
Works with no signal, which is most of the useful moments
The four meanings come from the same group, so the wrong ones are plausible, not silly.
Ten quick questions on what they mean
Recognising a sign and producing its meaning are different skills, and only one of them is tested.
Four meanings, one sign, drawn from the group you are looking at
Never asks you to tell apart two signs that are drawn the same
A score at the end and another ten whenever you want them
'Not yet' brings a sign back sooner; a sign known five times stays away.
Or flip through them like flashcards
The old way, because it works: sign, guess, turn it over, next.
The full list or just the group you picked
Swipe or use the arrows — one hand, one thumb
Good for the five minutes before you go in
One group of signs is free; the whole library comes with the unlock.
