Driving in Ireland: A Stress Free Guide

Share this
Driving in Ireland can be one of the most rewarding ways to freely explore the country’s beautiful scenery, charming towns, and hidden gems. However, driving in Ireland can feel intimidating for visitors unfamiliar with local rules and roads. In this guide, we’ll cover everything you need to know to confidently and safely drive in Ireland.
Key Info: Driving in Ireland for Tourists

1. Drive on the Left
In Ireland, cars drive on the left-hand side of the road. This is perhaps the most significant adjustment for visitors from countries like the United States or continental Europe, where people typically drive on the right. A helpful mantra is: “Left is best”. Be extra mindful at intersections and roundabouts.
Tip: When returning to your car after a stop, remember to orient yourself again to driving on the left – this is where most people forget!
2. The Roads Are Not All Narrow
Contrary to popular belief, not every road in Ireland is a narrow country lane with grass growing up the middle. While such picturesque roads do exist, especially in rural areas, Ireland also has many well-maintained highways and national roads, particularly around major cities and tourist destinations.
Essential Rules of the Road

1. Speed Limits
Speed limits are clearly signposted and vary by road type:
- Urban areas: 50 km/h (30 mph)
- National roads: 80-100 km/h (50-62 mph)
- Motorways: 120 km/h (75 mph)
Remember, speed limits are posted in kilometers per hour (km/h) in the Republic of Ireland, but in miles per hour (mph) in Northern Ireland. Be prepared for this change if you plan to cross the border.
2. Right of Way
At intersections, traffic on the main road has priority, unless otherwise indicated. At roundabouts, yield to traffic coming from the right unless signage directs otherwise.
3. Overtaking and Changing Lanes
When overtaking another vehicle, do so only when it’s safe. Remember to:
- Check your mirrors.
- Signal your intention.
- Return to the left lane after overtaking.
4. U-Turns and Pulling Over
U-turns are often prohibited in built-up areas, and pulling over should only be done if it’s absolutely safe and necessary. Always check your mirrors, signal, and slow down gradually.
Common Challenges (and How to Overcome Them)

1. Roundabouts
Roundabouts are common and may seem confusing, but they’re efficient once you get used to them.
- Always yield to traffic from the right.
- Use your indicator when exiting.
- Missed your exit? Don’t panic; you can circle back around.
2. Narrow Roads
Rural roads can be narrow, often requiring you to slow down or pull into a passing bay to let oncoming traffic pass.
Tip: Use Google Maps’ Street View to preview narrow roads before driving there.
3. Toll Roads
Some motorways, like the M50 around Dublin, use an electronic toll system with no booths. Pay online within 24 hours to avoid fines.

4. Road Signs
Irish road signs are generally straightforward, but it’s a good idea to familiarize yourself with them before you hit the road. The Road Safety Authority of Ireland offers resources that will help you understand the various signs and road markings.
Driving Safely in Ireland

1. Night Driving
Avoid driving at night in rural areas if possible. Street lighting is limited, and winding roads can be challenging in the dark.
2. Weather Conditions
Ireland’s weather can change rapidly. Keep your headlights on during rain or fog and ensure your wipers are functional.
3. Seat Belts and Mobile Phones
- Seat belts are mandatory for all passengers.
- Using a handheld phone while driving is illegal. Use hands-free features if needed.
Motorways vs. Rural Roads

1. Motorways (“M” Roads)
Motorways are Ireland’s fastest and safest roads, marked by blue signs and an “M” prefix (e.g., M50, M7). Use these for long-distance travel when possible.
2. National Roads (“N” Roads)
National roads use green signs with an “N” prefix (e.g., N4, N7).
3. Rural Roads
The charm of driving in Ireland lies in its scenic, winding rural roads. However, be prepared for sharp bends, livestock, and slower traffic. Local drivers are skilled at navigating these roads quickly, so don’t feel pressured to keep up if someone’s on your tail. When safe, pull over to let them pass.
Pro Tip: Rent a smaller car to navigate rural roads more easily.
Renting a Car in Ireland

1. Stick Shift vs. Automatic
Most rental cars in Ireland have manual transmissions (stick shifts). If you’re used to driving an automatic, request one well in advance. Automatics are in limited supply and may be more expensive.
2. Insurance Requirements
By law, all drivers in Ireland must have car insurance. Rental companies include basic coverage, but additional protection (e.g., for windscreen damage or tire punctures) is often worth the cost.

3. Driving License
- U.S. and EU/EEA residents can use their national licenses.
- Visitors from non-EU/EEA countries may benefit from an International Driving Permit (IDP) for easier translation.
Familiarize Yourself with Your Rental Car

Before you start driving, take a few minutes to familiarize yourself with your rental car’s key functions. This will help reduce stress and ensure you’re comfortable behind the wheel. Here’s a quick checklist:
- Mirrors: Adjust them for proper visibility.
- Indicators: Make sure you know how to signal.
- Headlights: Learn how to turn on and adjust the lights, as Ireland’s weather can change rapidly.
- Window Wipers: Rain is common, so this is a must.
- Defogging: Know how to clear your windows, especially during wet and foggy conditions.
Emergency Situations

In the event of an emergency, whether it’s a breakdown or an accident, it’s important to know what to do. For any serious incidents or if someone is injured, dial 999or 112 to contact the Gardaí (Irish police). For breakdowns, it’s advisable to contact your rental car provider immediately to report the issue.
Pro tip: Ask your rental company for their emergency contact details before you leave the lot. It’s also wise to check what their process is for breakdowns, especially if you’re driving in rural areas.
