Irish Road Signs: Learn, Revise and Test Yourself

Recognising a sign is only the first step. You also need to respond safely: look early, choose a safe speed, put the car in the right place, and make the decision before the hazard arrives.

This is a supplementary learning resource for learner drivers in Ireland. It is not an official RSA theory-test product. This guide supports your learning but does not replace the official RSA Rules of the Road or approved theory-test materials.

Based on current official Irish road-safety guidance.

Why signs matter

Signs support the decisions you make in a lesson, not just the names you revise.

  • Hazard awareness: a warning tells you what to look for before you reach it.
  • Correct speed: the sign tells you to slow down. It does not set a target to drive up to.
  • Lane and road position: arrows and lines tell you where to place the car.
  • Junction decisions: Stop, Yield and direction signs tell you whether to wait or which way to go.
  • Traffic controls: lights, crossings and roadworks signs tell you when to wait.
  • Theory-test revision: the categories match the signs learner drivers are expected to know.
  • Practical preparation: the test looks at how you respond, not only whether you can name the sign.

Shape and colour guide

Shape and colour are clues. They do not replace learning the individual sign.

  • Yellow diamond

    A yellow background and black border usually mark a warning. Read the symbol. The colour alone does not tell you the hazard.

  • Red border

    A red border on a white circular sign usually prohibits or restricts something. Stop is different: it is a red octagon, and it is the only regulatory sign in that shape.

  • Blue circle

    A blue circle with a white symbol is mandatory at a junction. It shows the direction you must take, such as turn left, keep left or straight ahead.

  • Orange temporary sign

    Orange with a black border means a roadworks warning. Take extra care and reduce speed. Do not treat it as an ordinary yellow warning.

  • Markings and signals

    White lines, yellow parking lines, traffic lights and pedestrian crossings are regulatory too. A green light still means you may go only if the way is clear.

Warning signs

Warning signs tell you a hazard is ahead, such as a junction, bend, roundabout or school. The RSA says they are diamond or rectangular, with a yellow background, a black border and a black symbol. Take special care. The symbol tells you which hazard.

  • Roundabout ahead

    Meaning. A roundabout is ahead.

    What to do. Slow early, look for traffic already on the roundabout, and plan your position and signal before you arrive.

    Common mistake. Leaving the slow-down until you are at the give-way line.

  • Dangerous bend ahead

    Meaning. A dangerous bend is ahead.

    What to do. Lose speed before the bend, stay on your own side, and be able to stop within the distance you can see.

    Common mistake. Braking hard in the middle of the bend.

  • Crossroads

    Meaning. A crossroads is ahead.

    What to do. Look both ways early and be ready for traffic from the side roads. The sign warns you. It does not decide who goes first.

  • T-junction

    Meaning. A T-junction is ahead.

    What to do. Ease off and read the junction before you reach it. Look for a Stop or Yield sign that tells you what you must do.

  • School ahead

    Meaning. A school is ahead.

    What to do. Slow down and expect children. Be ready to stop for a school warden.

    Common mistake. Treating the school warning as if it only applies at opening and closing time.

  • Pedestrian crossing ahead

    Meaning. A pedestrian crossing is ahead.

    What to do. Ease off, look for people waiting, and be prepared to stop. Do not overtake near the crossing.

  • Slippery road ahead

    Meaning. The road ahead may be slippery.

    What to do. Reduce speed before the hazard and avoid harsh braking or a sudden change of direction.

  • Traffic signals ahead

    Meaning. Traffic signals are ahead.

    What to do. Approach at a speed that lets you stop if the light is red or changes to amber.

    Common mistake. Speeding up to beat a light you cannot yet see.

  • Road narrows on both sides

    Meaning. The road narrows from both sides ahead.

    What to do. Slow down, hold your lane, and be ready to give space to oncoming traffic.

Regulatory and prohibitory signs

Regulatory signs show what the law requires. You must obey them. Prohibitory signs are usually circular, with a red border and black symbols on white. The Stop sign is the exception: it is the only regulatory sign in an octagon shape.

  • STOP

    Stop

    Meaning. You must stop completely before entering the major road, no matter how quiet it looks. It is the only regulatory sign in an octagon shape.

    What to do. Stop at the line, look every way, and move off only when you can join safely.

    Common mistake. Rolling through because the major road looks empty.

  • YIELD

    Yield

    Meaning. Give way to traffic on the major road. Do not proceed until it is safe. Other versions may read Yield Right of Way or Géill Slí.

    What to do. Slow early enough to stop if you need to. If the way is already clear, you may proceed without a full stop. Leave enough time to finish the manoeuvre.

    Common mistake. Treating Yield as a Stop, or treating it as permission to go without looking.

  • No entry

    Meaning. Do not enter. You may see this at the wrong end of a one-way street, sometimes with no-entry road markings.

    What to do. Do not pass the sign. Find another route.

    Common mistake. Following a sat-nav instruction that points the wrong way down a one-way street.

  • No left turn

    Meaning. A left turn is prohibited here.

    What to do. Do not turn left. Continue by a permitted route.

  • No right turn

    Meaning. A right turn is prohibited here.

    What to do. Do not turn right. Continue by a permitted route.

  • No U-turn

    Meaning. A U-turn is prohibited here.

    What to do. Do not turn the vehicle around at this point.

  • 50

    Speed limit

    Meaning. The number is the maximum speed for that stretch of road, not the speed you must drive at. The 50 on this drawing is only an example of the format.

    What to do. Do not exceed the number shown. Go slower when the road, weather, traffic or your view requires it.

    Common mistake. Driving at the number on the sign when the conditions are not fit for it.

Mandatory signs

Mandatory signs at junctions show the course you must take. The RSA describes them as blue and white. Follow the arrow. A blue circle is not a warning and it is not a prohibition.

  • Keep left

    Meaning. You must keep to the left of the obstruction or island.

    What to do. Move left in good time, after checking it is safe, and pass on the left side.

  • Turn left

    Meaning. You must turn left.

    What to do. Signal and take the left turn. Do not continue straight or turn right.

    Common mistake. Confusing this blue sign with the red-bordered No left turn sign.

  • Straight ahead

    Meaning. At the entrance to a one-way street, this sign means proceed straight ahead.

    What to do. Enter only in the direction shown. Once on the one-way street, still drive on the left unless you are overtaking or positioning for a right turn.

Information and direction signs

Information signs give directions and distances. The RSA describes three formats: blue signs with white letters on motorways, green signs with white letters on national roads, and white signs with black letters on regional and local roads.

  • Motorway

    Motorway direction

    Meaning. Blue signs with white letters give directions on motorways. The word on this drawing shows the colour format only. It is not a route instruction.

    What to do. Read the direction early and choose the lane in good time. Motorway rules apply once you have entered.

  • National

    National road direction

    Meaning. Green signs with white letters give directions on national roads. The word on this drawing shows the colour format only.

    What to do. Read the destination and route number early enough to position the car without a late swerve.

  • Local road

    Regional or local direction

    Meaning. White signs with black letters give directions on regional and local roads. The words on this drawing show the colour format only.

    What to do. Use the sign to confirm the road, then return your attention to the junction.

Temporary roadworks signs

Roadworks warnings use the same diamond or rectangular shape as other warnings, but they are orange with a black border and black symbols or words. Reduce speed and expect the layout to change. Stop and Go control at roadworks is law, not advice.

  • Roadworks ahead

    Meaning. Roadworks are ahead. This warning is orange, not yellow.

    What to do. Reduce speed, watch for further signs, and expect workers, a narrower road or a changed layout.

  • Temporary traffic signals ahead

    Meaning. Temporary traffic signals are ahead at roadworks.

    What to do. Slow down and obey the temporary lights as you would any traffic light.

  • Flagman ahead

    Meaning. A person controlling traffic is ahead at roadworks.

    What to do. Slow down and be ready to stop for the controller's sign.

  • STOPGO

    Stop and Go

    Meaning. You must stop when the Stop side is shown. You may proceed only when Go or Téigh is displayed. Either word may be used.

    What to do. Stop and wait. Move only on Go or Téigh, and only when the way in front of you is clear.

    Common mistake. Edging forward while the board still says Stop.

Road markings

Road markings are traffic signs painted on the road. The RSA says they have the same status as upright signs. Obey the line nearest to you, and do not assume a broken line is always safe to cross.

  • STOP

    Stop line

    Meaning. A continuous white line across your side of the road. The word STOP may be painted with it. You must come to a complete stop before entering the major road.

    What to do. Stop behind the line, not on it or beyond it.

  • Yield line

    Meaning. A broken white line across your side of the road. A white triangular yield symbol may be painted with it. You must give way to traffic on the major road.

    What to do. Slow, look early, and stop if you need to. Do not enter until it is safe.

  • Continuous centre line

    Meaning. A single or double continuous white line divides traffic travelling in opposite directions. Keep to the left of it, except in an emergency or for access.

    What to do. Do not cross it to overtake or to cut a corner.

    Common mistake. Treating a continuous line like a broken line because the road looks clear.

  • Broken centre line

    Meaning. Short broken white lines divide traffic travelling in opposite directions. Do not cross them unless it is safe to do so.

    What to do. Cross only when you can see a safe gap and you can return to your own side without forcing anyone to brake.

  • Double yellow lines

    Meaning. Double yellow lines mean no parking at any time.

    What to do. Do not park there. A single yellow line is different: it applies during the times on the nearby plate.

    Common mistake. Stopping on double yellow lines for a short wait.

Traffic lights and pedestrian crossings

Traffic lights and pedestrian crossings tell you when to stop and when you may go. A green light is not a right of way. At a pelican crossing, a flashing amber light gives priority to pedestrians on the crossing.

  • Red

    Red light

    Meaning. Stop. Do not go beyond the stop line, or beyond the light if there is no line.

    What to do. Stop and wait. A green filter arrow is the only light that lets you move in its direction while red is also showing.

  • Amber

    Amber light

    Meaning. Do not go beyond the stop line, or beyond the light if there is no line. You may go on only if you are so close when amber first appears that stopping would be dangerous.

    What to do. Approach at a speed that lets you stop. Do not speed up to beat the light.

  • Green

    Green light

    Meaning. You may go on if the way is clear. Green is not a right of way. Give way to pedestrians who are crossing, and take special care if you are turning.

    What to do. Check the junction is clear, then move off. Do not assume other people will stop for you.

  • Flashing amber

    Pelican crossing

    Meaning. After the red light for drivers goes out, an amber light flashes. A flashing amber light at a pelican crossing gives priority to pedestrians on the crossing.

    What to do. Yield to people on the crossing. Wait until they have crossed and the way is clear.

  • Zebra crossing

    Meaning. The crossing is marked with black and white stripes and is sometimes marked by yellow flashing beacons. Drivers must stop to let a person cross, behind the stop line if there is one.

    What to do. Slow on the approach and be prepared to stop. A person does not have priority until they step onto the crossing, so do not force them to jump back.

    Common mistake. Overtaking or parking on the zig-zag markings.

Commonly confused signs

These pairs are easy to mix up. The difference is in the shape, the colour, or the line.

Stop and Yield

STOP

Stop

You must stop completely before entering the major road, no matter how quiet it looks. It is the only regulatory sign in an octagon shape.

YIELD

Yield

Give way to traffic on the major road. Do not proceed until it is safe. Other versions may read Yield Right of Way or Géill Slí.

Visual difference. Stop is a red octagon. Yield is an inverted triangle and may also read Yield Right of Way or Géill Slí.

What to do. At Stop, stop completely before the major road. At Yield, give way and do not enter until it is safe. You do not have to make a full stop at Yield if the way is already clear.

Yellow warning and orange roadworks

Dangerous bend ahead

A dangerous bend is ahead.

Roadworks ahead

Roadworks are ahead. This warning is orange, not yellow.

Visual difference. Both can be diamond shaped with a black border and a black symbol. The ordinary warning is yellow. The roadworks warning is orange.

What to do. For the yellow sign, prepare for the hazard in the symbol. For the orange sign, reduce speed and expect a changed layout, workers or temporary control.

No left turn and Turn left

No left turn

A left turn is prohibited here.

Turn left

You must turn left.

Visual difference. No left turn has a red border, a black arrow and a red diagonal bar. Turn left is a blue circle with a white arrow.

What to do. Do not turn left at the red-bordered sign. You must turn left at the blue sign.

Continuous and broken centre lines

Continuous centre line

A single or double continuous white line divides traffic travelling in opposite directions. Keep to the left of it, except in an emergency or for access.

Broken centre line

Short broken white lines divide traffic travelling in opposite directions. Do not cross them unless it is safe to do so.

Visual difference. A continuous white centre line is solid. A broken centre line is short white dashes. Both divide opposite flows of traffic.

What to do. Keep left of a continuous line except in an emergency or for access. Cross a broken line only when it is safe.

Irish road-sign quiz

Fourteen original questions. No account, no payment, and no score that claims to predict an official test.

Question 1 of 14

What should you do when you see this yellow diamond?

Choose an answer. You can use the number keys 1 to 4, or the arrow keys and Enter.

Road signs only help when you respond correctly

In a lesson, the useful sequence is the same each time. Name the sign, then show what you do with it.

  1. 1. Look well ahead.
  2. 2. Recognise the sign.
  3. 3. Check mirrors and surroundings.
  4. 4. Adjust speed, gear or position early.
  5. 5. Follow the instruction safely.

EDT lessons build that habit across the 12 required sessions. Pre-test lessons use it on busier roads when a test date is closer. Neither is a guarantee of a pass.

Questions

What types of road signs are used in Ireland?

The RSA divides traffic signs and road markings into regulatory, warning and information signs. Regulatory signs include upright signs, road markings and traffic lights. Warning signs are usually yellow with a black border. Roadworks warnings are orange. Information signs are blue on motorways, green on national roads, and white with black text on regional and local roads.

What do yellow diamond signs mean?

They warn of a hazard ahead, such as a junction, bend, roundabout or school. Take special care and read the symbol. Shape and colour are a clue. They do not replace learning the individual sign.

What do red circular signs mean?

Most signs that prohibit or restrict something are circular, with a red border and black symbols on white. You must obey them. The Stop sign is separate: it is a red octagon, and it is the only regulatory sign in that shape.

What do blue circular signs mean?

Mandatory signs that show the direction you must take at a junction are blue with white symbols. Follow the direction, such as turn left, keep left or straight ahead.

Are road signs examined during the driving test?

The RSA says you need to know the rules for the theory test and the driving test, and that you must respond correctly to signs on the road. This page does not describe the official marking scheme and the quiz score does not predict a test result.

Is this an official RSA road-sign test?

No. This is a free revision quiz from Trinity Driving School. It does not replace the official Rules of the Road or approved theory-test materials, and the score does not predict an official result.

Can driving lessons help me respond correctly to road signs?

Yes. Recognising a sign is only the start. EDT and pre-test lessons can help you look ahead, adjust speed and position, and make the decision the sign calls for. Lessons do not guarantee a theory-test or driving-test pass.

Where can I find the official Rules of the Road?

The Road Safety Authority publishes the Rules of the Road on rsa.ie, including a free PDF. The Department of Transport Traffic Signs Manual gives the detailed standards used by road authorities.
