Driving on the Left: The Golden Rule
In the Republic of Ireland you drive on the left-hand side of the road, and the driver sits on the right of the vehicle. If you are used to driving on the right, this is the single biggest adjustment, and it matters even more in a larger, wider campervan or motorhome. Take it slowly for the first hour or two: the instinct to drift back to the "wrong" side returns most often at junctions, on quiet rural roads and when pulling out of fuel stations or car parks.
A few habits that keep you safe: at roundabouts you travel clockwise and give way to traffic coming from your right. When turning, remember that a left turn is the "easy" turn into the near lane, while a right turn crosses oncoming traffic. Keep the centre line on the driver's side of the van, which naturally positions you correctly in the lane. Sat-nav with clear lane guidance is genuinely helpful, and it is worth having a passenger act as a second pair of eyes at busy junctions while you adjust.
Licences and Minimum Age
Most campervans and standard motorhomes you can hire in Ireland fall under category B (vehicles up to 3,500 kg), so an ordinary full car licence covers them. Always confirm the maximum authorised mass (MAM) of your specific vehicle, as a small number of larger motorhomes exceed 3,500 kg and require category C1.
- EU, EEA and UK licences are valid for driving in Ireland without any extra paperwork.
- Visitors from outside the EU/EEA (for example the USA, Canada, Australia) can drive on a valid national licence, but carrying an International Driving Permit (IDP) alongside it is strongly recommended and is sometimes required by rental companies.
- Carry your physical licence (and IDP if applicable) with you while driving; photos on a phone are not accepted at a checkpoint.
For campervan rental in Ireland, the minimum age is typically 21 to 25 depending on the company and vehicle size, and many operators add a young-driver surcharge for under-25s. Some also set a maximum age or ask for a certain number of years' licence-holding experience, so check the rental terms before you book.
Speed Limits (in km/h)
All Irish speed limits and distances are in kilometres, shown on white circular signs with a red border. Even if your van's speedometer also reads in mph, get used to working in km/h. The standard limits are:
- 50 km/h in built-up areas and towns (sometimes lower, 30 km/h, in residential or school zones).
- 80 km/h on regional and local roads (the default rural limit, including many narrow routes where 80 is the legal maximum, not a target).
- 100 km/h on national roads (the green-signed N routes).
- 120 km/h on motorways (the blue-signed M routes).
A heavily loaded motorhome handles very differently from a car: braking distances are longer, crosswinds on exposed coastal stretches push you around, and cornering needs more care. On winding regional roads in the west, your comfortable speed will often be well below the posted 80, and that is completely normal. Speed is enforced by fixed and mobile cameras (look out for the GoSafe vans), and penalties apply to the registered keeper, which on a hire vehicle means charges passed on to you.
Tolls and the M50 eFlow System
Most Irish toll roads use conventional barrier plazas where you stop and pay by cash, card or electronic tag; these sit on motorways such as the M1, M4, M7 and M8. Keep some euro coins handy as a backup, and use the clearly signed manned or card lanes rather than the tag-only lanes if your van is not fitted with a tag.
The crucial exception is the M50, Dublin's orbital motorway, which is barrier-free. There are no booths: cameras read your number plate as you pass the toll point near the West-Link bridge, and you must pay the charge separately. This catches out many visitors. You have two options:
- Pay online (or by phone) through the eFlow system by 20:00 the following day. Miss that deadline and the toll escalates into penalty charges that the rental company will pass on to you, often with an admin fee.
- Have the vehicle fitted with an electronic tag, which pays automatically.
Before you drive away from the depot, ask the rental company directly whether the van has a working tag and how M50 (and other) tolls are handled on your agreement. If there is no tag and your route touches the M50, set a phone reminder to pay via eFlow the same evening.
Drink-Driving, Seatbelts and Child Seats
Ireland enforces strict drink-driving limits and roadside testing is routine. The general limit is 0.5 g/L of blood alcohol, but for novice drivers (within their first two years), learner drivers and professional drivers the limit is just 0.2 g/L, which effectively means zero. The only safe approach is not to drink at all if you are driving, which is easy and pleasant in a campervan: park up at your overnight spot first, then enjoy the local stout or whiskey.
- Seatbelts are compulsory for the driver and all passengers, front and rear, and the driver is responsible for ensuring under-17s are properly restrained.
- Children under 150 cm and 36 kg must use an appropriate child seat or booster suited to their height and weight. Arrange these with your rental company in advance if travelling with little ones.
- Using a hand-held mobile phone while driving is illegal and heavily penalised.
Narrow Rural Roads, Boreens and Livestock
Some of the finest Wild Atlantic Way driving, the Ring of Kerry, Connemara, the Beara and Dingle peninsulas, takes you onto narrow, twisting lanes the Irish call boreens. Many are single-track with grass growing up the middle, bounded by stone walls or high hedges with little room to spare on either side of a motorhome.
The etiquette is straightforward and friendly. Use the marked passing places (often a slightly wider patch of verge) to let oncoming traffic or faster vehicles through; pull in on your left, and if the passing place is on the right, wait opposite it so the other driver can use it. A raised hand or a flash of acknowledgement is the local thank-you. Reverse readily if you are nearer a passing point than the oncoming vehicle.
Expect livestock: sheep, cattle and the occasional herd being moved along the road are part of rural life, especially in the west and on commonage near the coast. Slow right down, give them space, and never sound your horn aggressively. Watch too for cyclists, walkers and tractors. On the popular loops such as the Ring of Kerry, large tour coaches traditionally travel anti-clockwise, so following that direction reduces awkward meetings on the tightest bends.
Headlights, Visibility and Weather
Irish weather changes quickly and low cloud, mist and heavy rain are common even in summer. Use dipped headlights in poor visibility, fog, heavy rain and at dusk; it helps others see your van as much as it helps you see. Rural roads are often unlit at night, so a slower, cautious pace after dark is wise, particularly given the boreens and wandering animals. Keep your windscreen and lights clean, as coastal driving throws up a lot of spray and grime.
Fuel, Diesel and Refuelling
The vast majority of campervans and motorhomes in Ireland run on diesel, labelled at the pump and often signed in green; double-check before you fill, because misfuelling is an expensive mistake. Filling stations are plentiful in towns and along national routes, but they thin out considerably on remote peninsulas and in the mountains.
- Adopt a simple rule: refuel when you reach half a tank rather than running low, especially before heading into sparsely populated areas of the west and northwest.
- Larger forecourts and supermarket stations (such as those attached to Circle K, Applegreen and Maxol) usually have the easiest access and turning room for a bigger vehicle.
- Sundays and rural evenings can mean shorter opening hours, so plan your last fill of the day accordingly.
Parking a Motorhome and Emergencies
Parking a campervan needs a little forethought because of its height and length. In towns, watch for height-barrier car parks that exclude motorhomes, and favour long-vehicle or coach bays where available. Pay-and-display and disc-parking zones are common; observe the marked restrictions and keep clear of yellow lines. Many trailheads, beaches and scenic viewpoints along the Wild Atlantic Way have generous car parks suited to larger vehicles, but overnight parking rules vary, so use designated campsites, aires and certified locations for sleeping rather than assuming wild overnighting is permitted.
In an emergency, the number to call in Ireland is 112 (the Europe-wide number) or 999; both reach the Garda (police), ambulance, fire and coastguard, and both work from any mobile. Keep the rental company's breakdown line saved in your phone, and note that on remote roads mobile coverage can be patchy, so it is worth telling someone your rough route for the day.
