Whether you’re planning a holiday to Ireland, visiting for work, or taking any other kind of trip, it’s vital that you understand the rules of the road and know the differences between driving in Ireland and driving in your home country. It’s also a good idea to ensure that you prepare for any unexpected eventualities that could happen by purchasing AA European breakdown cover before you go.
We’ve put together some guidance for safe and legal driving in Ireland to help you prepare. Here’s a run-through of key things you need to know about driving in Ireland, including details on speed limits and penalties, vehicle insurance, and travelling in an electric car.
Important information for driving in Ireland
In an emergency, dial 999 or 112 for police, ambulance, or fire brigade assistance.
This guide covers driving in the Republic of Ireland. Rules in Northern Ireland may differ, as Northern Ireland is part of the UK.
What documents do I need to drive in Ireland?
You should carry the following documents when driving in Ireland:
- A valid UK-issued driving licence. If you live in the UK and hold a valid UK driving licence, you can drive in Ireland.
- A third-party motor insurance certificate. In Ireland, all vehicles must have third-party insurance as a minimum.
- V5 registration document. Carry the original V5 registration document and a copy.
- Proof of rental or permission to drive. If the vehicle you’re driving is rented or not registered in your name, you’ll need to carry a rental agreement or letter from the registered owner to prove you have permission to drive it.
- Warning triangles. Warning triangles are compulsory for certain commercial goods vehicles but are not compulsory for private vehicles. Carry one is still recommended.
Drivers are recommended to carry a first aid kit, fire extinguisher and reflective jacket, although these items are not compulsory in private cars.
Road rules in Ireland
What is the legal age to drive in Ireland?
You must be at least 17 years old to drive in Ireland.
What side of the road do I drive on in Ireland?
As in the UK, cars in Ireland drive on the left side of the road.
Who has priority?
At uncontrolled junctions, drivers must give way to traffic travelling on the main road. Where roads are of equal importance, drivers should give way to traffic approaching from the right. When entering a roundabout, you must give way to traffic already on the roundabout, unless road signs indicate otherwise.
How do I overtake?
Drivers in Ireland drive on the left and overtake on the right. You should not overtake if doing so would cause danger or inconvenience to other road users.
Speed limits in Ireland
Speed limits in Ireland are given in kilometres per hour (km/h) rather than miles per hour (mph), which can cause some initial confusion. Many vehicles show speed in both mph and km/h, but check before setting off.
Speed limits in Ireland are as follows:
- Motorways: 120 kph
- National roads: 100 kph
- Regional and local roads: 80 kph
- Urban areas: 50 kph
- Special limits (i.e. near schools): 30 kph
Speeding penalties in Ireland
If you drive over the speed limit in Ireland, you can receive a fixed charge fine of €160 and 3 penalty points. If the fine is not paid within 28 days, it increases to €240. If it remains unpaid and the case goes to court, you could be fined up to €1,000 and receive up to 5 penalty points.
Speed camera detectors
Radar detectors are prohibited in Ireland and may be confiscated by the Gardaí.
Traffic lights and road signs in Ireland
The traffic light system in Ireland is similar to that in the UK, but the sequence of traffic lights is a little different. In Ireland, traffic lights typically go from red to green, then amber, red, and green again.
Red light: Stop before the stop line or if there isn’t one, stop before the light.
Amber light: If it is safe to do so, stop before the stop line or if there isn’t one, stop before the light. However, if the driver is too close to the stop line when the light turns to amber and it is unsafe to stop, they may proceed.
Flashing amber arrow: Continue in the direction indicated by the arrow if it is safe to do so, give way if other traffic is approaching.
Green light: Drive on if the way is clear and give way to any pedestrians crossing.
Green arrow or filter light: Continue in the direction indicated by the arrow, even if a red light is showing.
Road signs
Road signs in Ireland may show place names in both Irish and English. Warning signs are usually yellow diamonds with a black border and black symbol, while speed limit signs are shown in kilometres per hour.
Seat belt rules in Ireland
Everyone in the vehicle must wear a seat belt where fitted. As the driver, you’re responsible for making sure anyone under 17 uses a seat belt or suitable child restraint.
If you don’t wear a seat belt while driving, you could receive a fixed fine of €60 if you pay the fine and do not go to court. If the case goes to court and you are convicted, you could be fined up to €2,000.
Child seat rules in Ireland
Children under 3 years old must use an appropriate child restraint when travelling in a car, except in a taxi. They may travel in the front passenger seat only if they are in a rear-facing child restraint and the airbag is disabled.
Children aged 3 and over who are under 150cm tall or weigh less than 36kg must use an appropriate child restraint when travelling in a car fitted with seat belts.
Drink-and-drug-driving laws in Ireland
Drink-and-drug-driving offences are taken very seriously in Ireland. The Gardaí can test drivers at the roadside for alcohol or drug levels – these tests are mandatory. Refusing to be tested is an offence and you could be arrested.
Gardaí can also carry out roadside checkpoints and may require a breath test if they believe a driver has consumed alcohol. They must carry out a preliminary breath test at the scene of a crash where someone has been injured and requires medical attention.
The legal limit for drivers of private vehicles is 0.05% or 0.02% for newly qualified drivers with less than 2 years' driving experience.
Being caught and convicted of driving under the influence of alcohol or drugs leads to an automatic fine and a mandatory fixed-period driving disqualification. However the scale and severity of these penalties depends on the amount of alcohol detected in the driver’s system.
Mobile phones and headphones
It’s illegal to use a mobile phone while driving in Ireland unless it's with a hands-free system or you're calling 999 or 112 in an emergency. It's also illegal to hold a mobile phone while driving, or to support it with another part of your body, such as between your head and shoulder.
The penalty for using a mobile phone while driving is a fixed charge fine of €120 and 3 penalty points. If the fine is not paid within 28 days, it increases to €180. If the case goes to court, the penalty may increase further.
Lights in Ireland
All cars driven in Ireland must have working headlights, sidelights, indicators, rear lights, brake lights, reversing lights and number plate lighting.
Daytime running lights should be used in daylight, and dipped headlights should be used when visibility is poor, such as during heavy rain, fog, or snow.
Fog lights should only be used in dense fog or falling snow and should be switched off as soon as visibility improves.
Tyre requirements in Ireland
Tyres must have a minimum tread depth of 1.6 mm. Spiked tyres should not be used. Snow chains should only be used where there is a deep covering of snow or ice on the road, and snow socks may be used as an alternative. If winter tyres are used, they should be fitted on all wheels.
Vehicle insurance in Ireland
In Ireland, the law requires all drivers to have third-party liability insurance at a minimum. UK motor insurance generally provides the compulsory third-party cover required to drive in Ireland but check your policy before travelling.
Parking in Ireland
Many towns and cities in Ireland have on-street parking controlled by parking meters, pay-and-display tickets, or parking discs. Always check nearby signs for parking restrictions, payment requirements and time limits.
Parking is not permitted in places including:
- On double yellow lines at any time
- On single yellow lines during the times listed on nearby signs
- Within 9 metres of a road junction
- Within 9 metres on the approach side of a pedestrian crossing or pedestrian lights, unless passengers are getting in or out, or the vehicle is being loaded or unloaded
- At a bus stop area marked on the road
- On a pavement if it obstructs pedestrians
- On a cycle track
- Where signs show ‘No Parking’ or ‘Restricted Parking’ during the times listed
- In bus stops, taxi ranks, or loading bays
- In tram lanes
You can find out more about parking with our guide on where not to park in Ireland.
Disabled parking in Ireland
Ireland recognises disabled parking badges issued by authorities in other countries, provided the badge displays the wheelchair symbol. Badge holders may use reserved disabled parking spaces, but local rules can vary. You must not park on single or double yellow lines or anywhere that may cause an obstruction. In private car parks, check local notices or ask an attendant for details.
Parking fines in Ireland
If you park illegally, you may be fined, clamped, or towed away. Wheel clamps are used in Ireland, and a release fee of around €80 may apply. Vehicles causing an obstruction, or vehicles that have been parked dangerously, may also be removed.
Fuel in Ireland
Petrol, diesel, and LPG are widely available in Ireland, including at local filling stations and motorway service stations. Petrol stations are usually open from around 07:30 to 22:00, and a growing number are open 24 hours a day.
The following fuel types are common:
- Unleaded petrol, 95 octane
- Diesel
- LPG
Cards are accepted at many service stations, but check before filling up, especially at smaller or automated pumps.
Visitors may bring up to 10 litres of fuel duty-free, but carrying fuel in spare cans on board ferries or hovercraft is prohibited.
Driving an electric vehicle in Ireland
Where can I charge my electric vehicle in Ireland?
There is a growing number of publicly accessible electric vehicle charging points across Ireland, especially in urban areas, such as Dublin – which is one of the better served locations for EV chargers. You can also find charging points to charge your car at motorway service stations, public car parks, and shopping centres.
If you’re planning a long journey or are travelling a considerable distance away from a highly populated urban area, it’s a good idea to research charging stations along your route before you set off.
You can find charging locations using websites such as Chargemap or ESB, or via apps such as Zapmap.
Drivers should not park in an electric vehicle charging bay unless they are charging. Since January 2023, illegally parking in an electric charging bay can result in an €80 fixed charge.
How to pay for electric vehicle charging
Most EV charging points require you to register via an app or website to pay. In general, providers offer you the choice of a membership in the form of a monthly subscription with a set monthly fee or a pay-as-you-go plan, whereby you only pay for the electricity you use.
Riding a motorcycle in Ireland
Motorcycle regulations
- Riders and passengers on motorcycles and mopeds must wear an approved crash helmet.
- Dipped headlights should be used during the day, and headlights must be used at night or when visibility is poor.
- Motorcycle tyres must meet the legal minimum tread-depth requirement.
- Learner motorcyclists must not carry a passenger.
- Protective clothing is strongly recommended.
Towing a caravan or trailer in Ireland
If you’re towing a caravan or trailer in Ireland, you must follow additional rules on motorway use, speed limits, vehicle size and loading.
Cars towing caravans or trailers must not use the outside lane of a motorway with three or more lanes.
Other key requirements and safety points include:
- The maximum permitted length for a car and caravan is 12 metres.
- The maximum permitted width is 2.55 metres.
- Vehicles should not tow more than one trailer.
- The loaded weight of the caravan or trailer must not exceed the car’s towing capacity.
- The combined weight of the loaded car and loaded caravan or trailer must not exceed the car’s maximum train weight. You can check this at a local weighbridge or by calculating the combined loaded weight before travelling.
- Do not overload the car, caravan, or trailer.
Speed limits for cars towing caravans or trailers
The speed limit for cars towing a caravan or trailer is 80 km/h on motorways and national roads.
Toll charges in Ireland
Several roads, tunnels, and bridges in Ireland charge tolls. If the car you’re driving is legally registered in your name, you’re responsible for ensuring the toll is paid, even if you’re not the one driving at the time. Failure to pay can result in fines or even prosecution.
How to pay for tolls in Ireland
Payment methods vary by toll, but payment can usually be made in cash at the barrier or electronically using an eToll tag. The tag attaches to your windscreen and allows you to pass through participating toll roads without stopping, with the charge collected automatically from your account. Several companies provide electronic toll tags in Ireland, and they operate on the same national tolling system, so motorists usually only need one tag for toll facilities across the country.
The M50 Dublin ring road uses barrier-free tolling, so there is no toll booth. Drivers can pay using an eToll tag, a video account, online, by phone or at Payzone outlets. If you are not registered, pay by 20:00 the day after your journey to avoid penalties.
Roadside assistance in Ireland
If your car breaks down on a motorway, pull as far onto the hard shoulder as possible, turn your wheels to the left and switch on your hazard lights.
If you can't reach the hard shoulder, switch on your hazard lights and leave the vehicle by the left-hand door when it is safe to do so. Move away from the carriageway and do not attempt repairs yourself.
In an emergency, call 999 or 112. Emergency telephones are also available along motorways and connect to the nearest Garda station. If an accident causes injury or property damage in a public place, the driver must give their name and address to Gardaí, either at the scene or at the nearest Garda station. You should also report accidents to your insurer as soon as possible.
If you’re a UK breakdown member you can call us on (0)0800 88 77 66 44 to report your breakdown. It’s also a good idea to call TII's Motorway Control Centre on 0818 715 100 to let them know what’s happened and where you are.
