Ireland Driver Theory Test Study Guide 2026

How the Driver Theory Test works

The Driver Theory Test checks that you know the rules of the road before you start driving. You must pass it before you can apply for your first learner permit. The test is run for the Road Safety Authority (RSA) and you book it online at theorytest.ie.

The questions are picked at random from a large question bank. They cover topics such as legal matters and the rules of the road, managing risk, safe and responsible driving, technical matters about your vehicle, and road signs.

On the day

• Bring the ID that the test centre asks for. Staff check and scan it when you arrive. Without the right ID, or if you are late, you cannot sit the test and you lose your fee.
• You see a pass or fail result on screen at the end. A link to your score report is emailed to you. The report shows which topic areas you got right or wrong.
• If you need help, ask for Test Day Assistance when you book. Options include voiceover through headphones, extra time, and a reader who reads the questions and records your answers.
• From 1 November 2026, you must be at least 15 on the day of the test.

There is no limit on how many times you can sit the test. If you fail, the test provider advises waiting at least three business days before you try again, so you have time to revise.

From learner permit to full licence

Learning to drive a car in Ireland follows a set path. Each step must be done in order.

1. Pass the Driver Theory Test.
2. Apply to the NDLS for your first learner permit. The minimum age for a car (category B) learner permit is 17. Your first application needs your theory test certificate and an eyesight report dated within one month.
3. Take 12 Essential Driver Training (EDT) lessons with an Approved Driving Instructor (ADI), and practise with an accompanying driver.
4. Hold your first learner permit for at least six months.
5. Pass the driving test. You get a Certificate of Competency, which is valid for two years.
6. Use the certificate to apply for your full licence, then display N plates for two years.

Rules while you hold a learner permit

• You must be accompanied at all times by an ADI or by someone who has held a full licence for the same category for at least two years.
• Display L plates (a red L on a white background) on the front and rear of the car.
• You must not drive on a motorway. It is an offence to do so.
• You must not carry passengers who pay for the trip. Motorcycle learners cannot carry any passenger until they pass the test.
• Some learners must not tow a trailer.
• The car must be roadworthy, insured and taxed, with a valid NCT if it is due.
• Learner permits are generally issued for two years. If your permit lapses for five years or more, you must start again with a new theory test, a new first learner permit and all EDT lessons.

Essential Driver Training (EDT)

EDT is required if your first car learner permit was issued on or after 4 April 2011. It is 12 one-hour sessions with an ADI. Session 1 comes first. Sessions 2 to 8 can be taken in any order. Sessions 9 to 12 come after sessions 2 to 8 are done. The RSA recommends about two weeks between sessions so you can practise in between.

Your ADI stamps, dates and signs your EDT logbook after each session and uploads it to MyEDT. You cannot book your driving test until all 12 sessions show in MyEDT. Bring your completed logbook to your driving test.

Novice drivers

After you get your first full licence you are a novice driver for two years. The novice period only happens once.

Speed limits

Speed limits in Ireland are in kilometres per hour (km/h). A speed limit is the most you may legally drive. It is not a target. You must drive more slowly when the road, the weather or the traffic makes the limit unsafe.

Speed limit signs are white circles with a red border and black numbers. On many rural local roads you will see the rural speed limit sign instead: a white circle crossed by black diagonal lines, with no number. Since 7 February 2025 it means you must drive at 60 km/h or below. Before that date it meant 80 km/h.

Local councils set special limits, such as 30 km/h, with bye-laws, and many urban roads are moving to 30 km/h. On some roads, such as the M50, electronic signs show variable speed limits. The limit on the sign is the legal limit at that time.

Limits for some vehicles

• Any vehicle towing a trailer, caravan or horsebox: 80 km/h, even on a motorway.
• Buses carrying standing passengers: 65 km/h.
• Motorway toll lanes: no more than 50 km/h.

Speed is a factor in about one in three fatal crashes in Ireland. The RSA says that when a pedestrian is hit at 80 km/h, about 9 in 10 are killed. At 60 km/h it is about 5 in 10, and at 50 km/h about 3 in 10.

A speeding fixed charge is €160 and 3 penalty points if you pay within 28 days. You must not break the speed limit, even when overtaking.

Alcohol, drugs and penalty points

Ireland has two sets of alcohol limits. Specified drivers have a lower limit. They are learner drivers, novice drivers in their first two years, professional drivers (such as bus, truck and taxi drivers) and anyone driving without a valid licence or permit.

Every drink-driving conviction leads to a disqualification. At the lowest levels, a fixed penalty notice may be offered instead of court:

• Experienced driver, 50 to 80 mg: €200 and 3 months off the road.
• Experienced driver, 80 to 100 mg: €400 and 6 months off the road.
• Learner, novice or professional driver, over 20 mg up to 80 mg: €200 and 3 months off the road.
• The maximum penalty in court is a €5,000 fine, 6 months in prison, or both.

Gardaí can breath test any driver at an authorised checkpoint, and refusing a test is an offence. They also test drivers at crashes where someone is injured.

Drugs

It is illegal to drive while impaired by any drug, including medicine from your doctor. For cannabis, cocaine and heroin, driving over a set limit is an offence even if you do not seem impaired. Gardaí can use roadside saliva tests and impairment tests.

Penalty points

You get penalty points if you pay a fixed charge or are convicted in court for an offence that carries points. Points apply to learner permits as well as full licences.

• Points stay on your record for three years.
• Pay a fixed charge within 28 days. In the next 28 days it costs 50% more. After 56 days it goes to court.
• Camera fines go to the registered owner, who must name the driver if they were not driving.
• When a disqualification starts, you must send your licence to the NDLS within 14 days.

Junctions, roundabouts and yellow box junctions

At most junctions, signs and road markings tell you who has priority. A broken white yield line means you must give way to traffic on the major road. A continuous white stop line means you must come to a complete stop before you go.

The stop sign is a red octagon, and it is the only regulatory sign with eight sides. You must stop fully, however quiet the road looks. The yield sign is a triangle pointing down with a red border.

Turning right

When you turn right, give way to oncoming traffic that is going straight on or turning left, and to pedestrians crossing the road you are turning into. Never cut the corner.

Roundabouts

By law, you must turn left when you enter a roundabout, so traffic goes round clockwise. Treat a roundabout like a junction: give way to traffic already on it, which comes from your right. Signal left to leave once you have passed the exit before the one you want.

On a roundabout with two lanes, choose your lane early and follow any lane markings. To take the first exit on the left, use the left lane and signal left. To go straight ahead, use the left lane. To turn right, use the right lane, signal right and keep to the inner lane until you leave.

Yellow box junctions

A yellow box is a criss-cross yellow pattern painted on the road at a busy junction. You must not enter the box unless you can clear it without stopping. The one exception is when you are turning right. You may then wait in the box for a gap in the oncoming traffic.

Traffic lights

• Red: stop at the stop line.
• Amber: stop, unless it would be dangerous to do so.
• Green: go if the way is clear. If you are turning, give way to pedestrians who are crossing.
• Green filter arrow: you may go in the direction of the arrow if it is safe, even when the red light is on.
• Flashing amber arrow: go in that direction only if it is safe, giving way to approaching traffic.

At some lights there is an advanced stop line for cyclists. Drivers must wait behind the first white line so cyclists can move off first.

Motorways

Traffic on motorways moves fast, so you need to plan ahead and keep a safe distance. All motorway signs are blue with white writing.

Who may not use a motorway

• Learner drivers, and anyone without a full licence for the vehicle
• Vehicles that cannot reach and keep up at least 50 km/h
• Vehicles with an engine of 50 cc or less
• Pedestrians, cyclists and anyone moving animals
• Users of motorised wheelchairs

Joining, lanes and overtaking

Use the slip road to build up speed. Check your mirrors and blind spot, signal, and give way to traffic already on the motorway. Once on the motorway, drive in lane 1 (the left lane) unless you are overtaking.

• Overtake on the right only. The one exception is in slow-moving queues, when the lane on your right is moving more slowly than yours.
• Change lanes one at a time and signal every time.
• Goods vehicles over 3,500 kg and vehicles towing must not use the outside lane of a motorway with three or more lanes, unless the other lanes are blocked.
• Never reverse, turn, or cross hatched markings. If you miss your exit, go on to the next one.
• Countdown markers show 300 m, 200 m and 100 m to the next exit. Move into lane 1 well before your exit.

The hard shoulder

On a motorway, use the hard shoulder only in an emergency or when a Garda tells you to. Never use it to overtake. Stopping on a motorway is only allowed in an emergency.

If you break down

1. Move onto the hard shoulder, as far left as you can, and switch on your hazard warning lights.
2. Put on a high-visibility vest. Get out by the left-hand doors, away from the traffic.
3. Wait well behind the crash barrier, on the embankment side. Keep passengers and animals away from the road.
4. Call for help from a roadside phone, or by mobile, using the location marker posts or signs to say where you are.

Do not place a warning triangle on a motorway, and do not try to repair your car on the hard shoulder. If you cannot get out safely, stay in the car with your seat belt on and your hazard lights flashing.

If you find yourself driving the wrong way, do not turn around. Pull onto the hard shoulder, stop, and call 999 or 112.

Sharing the road with vulnerable road users

Pedestrians, cyclists, motorcyclists and horse riders have no protection in a crash. Children and older people may also be slower to react. Drivers must look out for them and give them space.

Cyclists

When you overtake a cyclist, leave a gap of at least 1 metre where the speed limit is 50 km/h or less, and at least 1.5 metres where it is over 50 km/h. Before turning left, check your mirrors and look over your shoulder, because a cyclist may be in your blind spot.

Pedestrians and crossings

Where there is no footpath, pedestrians should walk on the right, facing oncoming traffic. Watch for them on country roads, especially at night.

• Zebra crossing: give way to pedestrians who are on the crossing.
• Pelican crossing: when the amber light flashes, give way to anyone on the crossing, then go if it is clear.
• Do not overtake at or near a pedestrian crossing. A stopped car may be hiding someone who is crossing.

Buses, trams and animals

• Let a bus that is signalling pull back out from a bus stop when it is safe.
• Trams are almost silent, so pedestrians may not hear them. Watch for people crossing near tram lines.
• Pass horses slowly and wide. Do not rev your engine or sound your horn near them.
• Watch for animals on rural roads, such as cattle and deer.

Bus lanes

During the hours shown on the sign, only buses and cyclists may use a normal bus lane, along with taxis working at the time. Do not drive in a bus lane during its hours of operation.

Road signs and markings

Irish road signs fall into a few main groups. Learn their shapes and colours, because you can often tell what a sign means before you can read it.

Regulatory signs

Blue circular signs, such as keep left and turn left ahead, tell you what you must do. Signs with a red circle tell you what you must not do.

Warning signs

Road markings

• Never cross a continuous white line in the centre of the road to overtake.
• A broken white yield line across your lane means give way to traffic on the major road.
• A continuous white stop line means stop completely before you go on.
• A yellow box means do not enter unless your exit is clear, except to turn right.

Your car: safety checks, NCT and documents

Tyres

• The legal minimum tread depth for most vehicles is 1.6 mm over the main tread. The RSA strongly recommends changing tyres at 3 mm.
• Do not mix radial and cross-ply tyres on the same axle. Tyres on each axle should match.
• Avoid second-hand tyres, because you do not know their history.
• A temporary space-saver spare is only for finishing your journey or reaching a tyre dealer. Do not go faster than the speed marked on it.

Lights

A car needs two headlights, two white sidelights and amber indicators at the front. At the rear it needs red tail lights, red brake lights, red reflectors, number plate lights and amber indicators. Use fog lights only in dense fog or falling snow, and switch them off when visibility improves. Use sidelights or parking lights when you park on an unlit road at night.

Seat belts and children

• Everyone in the car must wear a seat belt where one is fitted.
• The driver is responsible for making sure passengers under 17 use a seat belt or a suitable child seat.
• Children under 150 cm or 36 kg must use a child restraint that suits their height and weight.
• Never fit a rear-facing baby seat in a front seat that has an active airbag.

The National Car Test (NCT)

You can test up to 90 days early. Keep your NCT certificate safe, as a Garda may ask to see it. Using a car without a valid NCT certificate carries 5 penalty points on conviction and a fine of up to €2,500, and the Gardaí may seize the car.

Documents and insurance

Carry your driving licence or learner permit at all times when you drive. Your car must be insured and taxed. If you change your car, for example with a new engine or wheels, tell your insurer, because some changes can make your insurance invalid.

Safe driving habits

Following distance

Keep at least a two-second gap behind the vehicle in front. Pick a fixed point, such as a pole. When the vehicle ahead passes it, count two seconds. If you reach the point before you finish counting, you are too close. In bad weather, leave at least four seconds. On ice or snow, braking distances can be up to ten times longer.

Overtaking

Overtake on the right. You may pass on the left only when the driver ahead has signalled to turn right, when you are turning left at the next junction and have signalled, or in slow queues where traffic on your right is moving more slowly. Before you overtake, use mirror, signal, manoeuvre.

• Do not overtake near junctions, bends, dips, narrow roads or pedestrian crossings.
• Do not overtake in the left lane of a dual carriageway or motorway when traffic is moving normally.
• When you change lanes, give way to traffic already in that lane. Signalling does not give you the right of way.

Phones and tiredness

Using a hand-held mobile phone while driving is an offence. Texting while driving is a separate offence that goes to court. The RSA says drivers using a phone are about four times more likely to crash. If you feel tired, stop somewhere safe and rest.

In an emergency

Call 112 or 999 for the Gardaí, an ambulance or the fire service.
