Driving in Ireland: 20 Must-Read Tips Before Renting a Car in Ireland

Driving in Ireland is one of the best ways to experience this extraordinary country, and I say that as someone who spent three weeks doing exactly that on a solo road trip around the island, and returned a second time for a month.

Ireland rewards drivers in a way that buses and organized tours simply cannot replicate. The most breathtaking landscapes, the hidden coves, the ancient ruins down unmarked lanes, the cliffside viewpoints with nobody else around, these are all things you find when you have a car and no fixed schedule. The Wild Atlantic Way alone is worth renting a car for.

That said, driving in Ireland as a tourist comes with its own set of rules, quirks, and challenges that are worth knowing before you arrive.

In this guide I cover everything you need to know: the documents required, car insurance, driving on the left, speed limits, toll roads, and the best road trip routes. I also share the personal trick I use to avoid getting on the wrong side of the road, which has saved me more than once.

Driving in Ireland: Key Facts at a Glance

🚙 Do You Need a Car in Ireland?

Whether you need a car in Ireland depends on your travel plans and itinerary. For instance, public transportation is reliable in most large cities like Dublin, Cork, and Galway.

Furthermore, when the weather allows it, all cities are very walkable, making them easy to explore on foot.

However, if you desire to visit other parts of Ireland, such as the more rural or remote areas, a car will give you flexibility and easier access.

🚙 Is it Easy to Drive in Ireland?

Generally, driving in Ireland might seem a bit challenging because Ireland is well-known for rural roads, which can be narrow and winding, meaning proper caution is required. 

Therefore, it’s essential to familiarize yourself with the local traffic laws before your trip, and when driving in Ireland, be sure to pay attention to signage to avoid any issues. 

🚙 Can Americans Drive in Ireland?

Americans can drive in Ireland, but only if they hold a valid U.S. driver’s license, which allows them to drive within the country for up to 12 months.

However, generally, if anyone desires to rent a car in Ireland, they may be asked to provide an International Driving Permit, so it is better to obtain it to ensure compliance with local requirements. 

🚙 Which Side of the Road Do You Drive in Ireland?

In Ireland, traffic flows on the left side of the road like in the United Kingdom.

Therefore, vehicles travel in the opposite direction compared to most countries where driving is on the right side of the road.

Since I am coming from one of those countries, I have my own strategy to avoid a car accident, which is making sure that every time I drive, I am in the middle of the road, a reference that, for me, is easier to notice than anything else.

If I find myself driving closer to the roadside, it means I am in the wrong lane. I hope it helps.

20 Things to Know Before Driving in Ireland

1. Driving Requirements in Ireland

📄 International ID/Passport

A crucial requirement is a valid international identification document, such as a passport or ID.

It is especially important because it serves as proof of identity and nationality by authorities in case of any traffic-related incidents. 

📄 Driver’s License/International Driver’s License

If you are a visitor from another country, you can drive in Ireland using a valid driver’s license from your home country for the last two years.

It is recommended to carry an International Driving Permit (IDP) alongside your driver’s license, which serves as an official translation of your license.

However, it is not always required, especially if your driving license is from a country whose language is in Roman letters.

Some car rental companies are stricter than others, so please make sure you confirm this requirement with the company of your choice.

📄 Age requirement

Generally you must be at least 25 to rent a standard car, 27 to rent people carriers and minivans, and 30 to rent larger luxury cars and SUVs. Age requirements vary between companies, so always check with your specific rental company before booking.

But if you are from an EU country and have an EU driver’s license, an IDP is not required for car rental agencies.

📄 Vehicle Registration Document (V5)

If you are driving your own car in Ireland, another key requirement is the Vehicle Registration Document (V5), which provides proof of ownership and registration for your vehicle.

If you plan to rent a car, the rental agency typically provides the necessary documentation for the vehicle.

So, when driving in Ireland, ensure you have the V5 document readily available to comply with local regulations. 

📄 Rental Car Company Contract

When renting a car in Ireland, it is essential to understand and fulfill the driving requirements set by the rental car company. 

Each rental company may have specific terms and conditions outlined in the contract that you need to adhere to.

But usually, these requirements include providing a valid driver’s license, being 25 years old or older, and presenting a credit card for payment and security deposit purposes. 

Additionally, it is crucial to carefully review and understand the terms of the rental car contract, including any additional fees, insurance coverage, mileage limits, and fuel policies. 

2. Car Insurance

Having appropriate car insurance is a legal requirement in Ireland. If you’re renting a car, typically, the rental car agency provides basic insurance coverage. 

However, it is advisable to review the policy details and consider additional coverage options, such as Collision Damage Waiver (CDW) or Excess Insurance, to protect yourself against potential liabilities and reduce financial risk in case of an accident or damage to the rental car. 

Some car rentals include it, such as NewWay Car Rental, my favorite company for renting a car in Ireland. Their prices have absolutely everything included (except for the keys) so you don’t have to worry about anything else.

However, if you are from the US and your credit card company provides car insurance, you may want to check out other options on Discover cars, where the insurance is optional. This way you may be able to find much better deals of course.

In case you’re planning to drive your own car, ensure your existing insurance policy provides sufficient coverage for driving in Ireland. 

3. Narrow Country Roads and Passing Places

One of the biggest practical challenges for visitors driving in Ireland is the narrow country roads, particularly in rural areas like Connemara, the Dingle Peninsula, Kerry, and Donegal. Many of these roads are single-lane with passing places at intervals where one car must pull in to let the other pass.

The unwritten rule is simple: whoever reaches the passing place first pulls in and waits. Flash your headlights or give a wave to thank drivers who pull in for you. This is standard Irish road etiquette and ignoring it will create frustration quickly.

On particularly narrow roads, slow down significantly and keep your wing mirrors in mind. Hedgerows in Ireland grow right to the edge of the road and are an extremely common cause of minor scratches on rental cars. Check your rental agreement carefully regarding hedge and bramble damage before you drive.

4. Right of Way at Junctions

At unmarked junctions and intersections in Ireland, you must yield to traffic approaching from the right. This is the same rule that applies in most European countries regardless of which side of the road traffic travels on.

In practice, always slow down at unmarked junctions, look right first, and proceed only when it is clear. At roundabouts, traffic already on the roundabout has priority over traffic entering it.

5. Use of GPS for Navigation

GPS navigation has become an essential tool for drivers, especially when exploring unfamiliar territories.

So, the use of GPS devices or navigation apps can enhance your driving experience in Ireland. 

Irish roads can be winding, and GPS systems offer a reliable way to navigate its picturesque landscapes and charming towns.

Furthermore, with accurate and up-to-date maps, GPS devices provide turn-by-turn directions, voice guidance, and real-time traffic updates to help you reach your destination efficiently. 

They also assist in locating nearby points of interest, such as fuel stations, restaurants, and attractions, making it easier to plan stops along your route. 

The most useful apps for driving in Ireland are Google Maps with offline maps downloaded before your trip, which is essential for areas with poor mobile coverage, and Waze for real-time traffic updates, particularly around Dublin. The Transport Infrastructure Ireland website publishes live traffic camera feeds and road condition updates, which are useful during winter trips. For parking in Dublin, the Dublin City Council parking app shows real-time availability in council-owned car parks.

6. Be Aware of Road Signage

When driving, it is generally crucial to be aware of signage and road markings, but it is even more important in new territories.

So, take your time to familiarize yourself with the various road signs and markings used in Ireland. 

For instance, road signs in Ireland come in different shapes and colors.

Specifically, triangular signs with red borders often indicate warning or caution, while circular signs with red borders indicate prohibitions. 

Other essential signs you should be aware of are speed limits, roundabouts, road markings such as solid white lines indicating overtaking, traffic signals, pedestrian crossings, and parking restrictions.

One important Ireland-specific note is that road signs in the Republic of Ireland show distances in kilometers, while in Northern Ireland distances are shown in miles. If your road trip crosses the border, which many do on the Wild Atlantic Way and northern coastal routes, be aware that speed limits also change at the border.

Northern Ireland uses miles per hour while the Republic uses kilometers per hour.

In Gaeltacht areas, which are Irish-speaking regions primarily in the west and northwest, road signs are in Irish only with no English translation.

Download the Google Maps offline map for Ireland before your trip and cross-reference with it in these areas as the Irish place names can be very different from their English equivalents.

7. Be Mindful of the Roundabouts

Roundabouts are a common feature of Irish roads, and it is important to be mindful of their proper usage to ensure a smooth and safe driving experience. 

So, remember to approach roundabouts with caution and at an appropriate speed, yield to traffic on the right, use indicators when entering, exiting, or changing lanes, and be sure you choose the right lane to avoid any accidents. 

8. Know When and Not to Overtake

Knowing when and when not to overtake is undoubtedly crucial for safe driving. And even though it sounds easy, it might be challenging if you’ve never driven on the left side of the road. 

Firstly, in rural areas and on single-lane roads, be sure to practice caution and overtake when there is sufficient visibility and a clear stretch of road ahead. 

When driving on multi-lane roads or highways, overtaking is generally permitted on the right-hand side. Still, ensure you have enough space and time to maneuver safely.

Generally, though, always be aware of oncoming traffic, and speed limits, and use common sense to judge whether to overtake or not. 

9. Excellent Road Conditions

Thankfully, roads in Ireland are in excellent condition, making driving and road trips easy for travelers.

From the major highways connecting cities to the scenic coastal routes, drivers can expect smooth surfaces and clear signage, ensuring a comfortable and safe journey. 

However, although all roads in Irelands are in excellent condition, remember that the countryside is famous for its narrow and winding roads, challenging those unfamiliar with rural roads.

Also, you will find a lot of cyclists along secondary roads, especially in summer. Give them plenty of space and slow down when passing. On narrow country roads this sometimes means pulling in slightly to let them pass safely.

10. Driving at Night Can Be a Challenge

Driving at night in Ireland can be challenging, just like in any other country. At night, visibility is reduced, and encountering road difficulties is more probable. 

Furthermore, in rural areas, street lighting may be limited, making it harder to see the road ahead.

Also, if you’re not familiar with the area, navigating dark, winding roads can be challenging. 

11. Stick Shift vs. Automatic Gears

If you plan to rent a car in Ireland, you might worry about what cars they prefer and have available. 

Generally, in Ireland, the majority of vehicles traditionally have a stick shift.

However, the popularity of automatic gears has been increasing in recent years, and you can find a growing number of cars with automatic gearboxes in Ireland, too.

So, ultimately, the choice between stick shift and automatic comes down to personal preference and driving style.  

12. Bring Car Seats for Children

Something to consider before any road trip is the safety of your little ones. 

Ireland, like many countries, has regulations regarding child safety in vehicles. Specifically, Irish law mandates that children under 150 cm tall or 36 kg in weight must use an appropriate restraint system. 

Therefore, it’s necessary to have a correctly fitted car seat or booster seat to ensure their safety during the journey. 

13. Toll Roads

While Ireland’s road network is extensive and well-maintained, some highways and bridges require payment tolls.

To access these toll roads, you can either pay in cash or use an electronic tolling system known as eFlow. 

However, it’s advisable to carry some coins in case you encounter a booth that only accepts cash.

Or, if you plan on frequently using toll roads, consider purchasing an eFlow tag in advance for convenient and hassle-free payments. 

WARNING – If you are using Dublin’s Ring Road, the M50 motorway, you should be aware that barrier-free tolling is in place between Junction 6 (N3 Blanchardstown) and Junction 7 (N4 Lucan). You are responsible for paying the Toll. The easiest way to pay is on their site, before your journey, or before the 8 pm deadline. The toll is approximately €3.10 for a car. If you rent a car and do not pay, the rental company will charge the amount plus an administration fee to your credit card, typically significantly more than the original toll.

Other tolls are:

• The Dublin Port Tunnel charges approximately €3.10 for cars during off-peak hours and more during peak times.
• The M1 between Dublin and the border with Northern Ireland has a toll plaza at Gormanston.
• The M8, M7, and M9 motorways south of Dublin have several toll plazas.

Budget approximately €10 to €20 in tolls for a week-long road trip, depending on your route.

14. Gas in Ireland

⛽️ Gas Stations in Ireland are Smaller Compared to Standard Gas Stations

Gas stations in Ireland tend to be smaller, meaning space limitations. Therefore, it’s best to plan your refueling stops accordingly, especially when traveling long distances between towns. 

Keeping an eye on your fuel gauge and locating gas stations along your route will ensure a smooth and uninterrupted journey across the country.

⛽️ Few Gas Stations in Rural Areas

Traveling through rural areas in Ireland may present a challenge when trying to find gas stations.

The countryside is vast, but with scattered villages and towns and a small population, so there are fewer options for refueling. 

Therefore, be sure to plan your journey accordingly, ensuring you have enough fuel to reach the next available gas station.

In fact, it’s recommended to fill up your tank each time you find a gas station to avoid any inconveniences or running out of fuel in remote areas. 

15. Ireland’s Driving Laws

📌 Traffic Lights

Traffic lights in Ireland play a vital role in ensuring road safety. Understanding their meanings is crucial for drivers. Red means stop, green means go, and yellow signals caution, like everywhere in the world. 

📌 Seat Belts

Wearing seat belts is a legal requirement, besides a safety tool, for all occupants in the vehicle. Failure to comply can result in penalties. So make sure to buckle up and prioritize safety on Irish roads. 

📌 Use of Mobile Phones

Mobile phone usage while driving is illegal, including texting or making calls. If necessary, you must utilize hands-free devices to stay focused, keep your hands on the wheel, and avoid distractions for a safer driving experience. 

📌 Drunk Driving

Ireland has stringent laws regarding driving under the influence of alcohol. The legal blood alcohol limit for most drivers is 50 milligrams per 100 milliliters of blood. 

Violators can face severe penalties, including fines, license suspension, and even imprisonment. So, always designate a sober driver and prioritize responsible choices.

16. Speed Limits in Ireland

Ireland has various speed limits depending on the type of road. Here is the official speed limit rule from the Road Safety Authority site.

The default speed limit in urban areas is 50 km/h unless otherwise signposted. 

On national roads, the limit is generally 80 km/h, while on motorways, it is 120 km/h.

Pay special caution in areas with reduced limits, such as school zones or roadworks, which usually have a speed limit between 30 to 60 km/h. 

One thing that you should keep in mind is that Ireland and Northern Ireland use different speedometers. Specifically, Northern Ireland uses miles, while Ireland uses kilometers.

You don’t need to learn these speed limits by heart, but you need to stay focused on the road and read the speed limit signs 🙂

17. Watch Out for Cars with Special Plates

In Ireland, cars with special plates indicate specific categories, such as learner drivers, newly licensed drivers, or vehicles for people with disabilities.

These plates warn other drivers to be cautious as well as exercise patience. 

Learner drivers are denoted by “L,” while “N” plates indicate a novice driver with a license of less than two years, and an “R” plate indicates that the car is registered with the Irish authorities. 

18. Emergency Hotlines in Ireland 

In case of emergencies on the road, it’s important to have the hotline numbers 999 or 112 for immediate assistance, including accidents, medical emergencies, or hazardous situations. 

19. Parking in Ireland

Parking in Irish city centers can be frustrating and expensive if you do not know the system. Here is what you need to know.

Pay and display: Most on-street parking in towns and cities operates on a pay and display system. Look for the yellow pay stations on the pavement, purchase a ticket for the time you need, and display it on your dashboard. Parking inspectors are active and fines are issued quickly.

Disc parking: In some towns, particularly smaller ones, a disc parking system operates. You purchase a cardboard disc from a nearby shop, mark your arrival time, and display it in your windscreen. The disc is usually free or very cheap and available at newsagents near the parking area.

Parking in Dublin: Dublin city center parking is expensive and spaces are limited. If your hotel is outside the city center, park there and use the Luas tram or Dublin Bus to get in. Many hotels outside the immediate center offer free or cheap parking. The ILAC Shopping Centre, Jervis Shopping Centre, and Smithfield Square car parks are among the most central and reasonably priced options.

Free parking: Outside major cities, parking is generally free and easy to find. In most small towns and villages you can park on the main street without charge.

20. Driving from the Republic of Ireland into Northern Ireland

Many visitors drive across the border between the Republic of Ireland and Northern Ireland, particularly those following the Causeway Coastal Route to see the Giant’s Causeway and the Dark Hedges or taking the northern coastal route toward Donegal.

The border crossing is completely open with no passport checks or customs stops as both countries are part of the Common Travel Area. You will simply cross without stopping.

However there are important practical points to be aware of:

Rental car cross-border permission: Most but not all Irish rental companies allow you to take their cars into Northern Ireland. You must confirm this with your rental company before your trip and get written confirmation. Some budget companies prohibit it and the insurance may be voided if you cross without permission.

Speed limits and road signs change: Northern Ireland uses miles per hour and distances in miles. The Republic uses kilometers per hour and kilometers. The change happens immediately at the border with no warning, so be aware of this before you cross.

Currency changes: Northern Ireland uses British Pounds Sterling, not Euros. If you plan to stop for fuel, food, or attractions in Northern Ireland, carry some Sterling or a card that does not charge foreign transaction fees.

Emergency number: The emergency number in Northern Ireland is 999, same as in the rest of the UK.

Renting a Car in Ireland

🚘 Is Renting a Car in Ireland Worth it?

Renting a car in Ireland can be worth it for many travelers. It offers the flexibility to explore the country at your own pace, access remote areas, and discover hidden gems.

Furthermore, Ireland’s scenic landscapes and countryside are best experienced with the freedom of a car. 

However, consider factors such as driving on the left side of the road, narrow rural roads, and parking challenges in cities.

But even though public transportation options are available, they may limit your Ireland itinerary.

So, assess your travel preferences, driving experience, and comfort level before deciding if renting a car in Ireland is the right choice for you.

🚘 How Much Does it Cost to Rent a Car in Ireland?

The cost of renting a car can vary depending on several factors, including the rental company, car type, rental duration, and the time of the year.

On average, you can expect to pay around €25 to €50 per day for a basic economy car.

However, there might be other additional costs, such as insurance, fuel, and toll fees.

Taking your own car to Ireland

If you are arriving in Ireland by ferry from the UK or France, you have the option of bringing your own car on board rather than renting one on arrival. Stena Line and Irish Ferries operate routes from Holyhead, Pembroke, and Cherbourg to Dublin, Rosslare, and Cork. If you bring your own car, make sure your existing insurance policy covers driving in Ireland and check whether your breakdown cover is valid there.
