If you're planning a self-drive trip to Iceland, this is usually one of the first practical questions that comes up, right after "do I need a 4x4?" Getting it sorted before you leave the rental lot means one less thing to think about once you're merging onto Route 41 toward Reykjavik, or navigating the roundabout at Hlemmur once you're in the city.
Quick answer: Iceland drives on the right-hand side of the road, and you overtake on the left. This matches the rules in mainland Europe, the US, and Canada, so travellers from those countries will find it familiar. If you're used to driving on the left, the UK, Ireland, Australia, New Zealand, South Africa, Japan, you'll need a short adjustment period, mainly at roundabouts, junctions, and when pulling out of car parks.
The short version: right-hand side, left-hand overtaking
Icelanders drive on the right side of the road, the same as the rest of continental Europe and North America. The steering wheel sits on the left side of the car, and when you need to pass a slower vehicle, you do it from the left lane. This rule applies everywhere in the country, on the Ring Road (Route 1), on gravel side roads, in Reykjavik traffic, and in winter conditions. Nothing about it changes seasonally or by region.
For travellers from the US, Canada, and most of the EU, this means driving in Iceland will feel close to driving at home. The habits you already have, staying right, passing left, checking your left mirror before merging, carry over directly.
Which side do you drive on if you're coming from a left-hand-drive country?
If your home country drives on the left, Iceland will feel mirrored, not foreign. The logic of the road is identical; only the side is flipped. Most visitors from these countries find they've adjusted within the first half-day of driving, usually by the time they've done a couple of roundabouts.
| Where you're from | Side you drive at home | Side you drive in Iceland | Adjustment needed |
|---|---|---|---|
| US, Canada | Right | Right | Minimal, habits transfer directly |
| Most of the EU | Right | Right | Minimal |
| UK, Ireland | Left | Right | Moderate, mirror your usual habits |
| Australia, New Zealand | Left | Right | Moderate |
| South Africa | Left | Right | Moderate |
| Japan | Left | Right | Moderate |
The "moderate adjustment" isn't about the driving itself, steering, braking, and reading the road are the same skills everywhere. It's about the handful of situations where muscle memory quietly takes over.
Where left-side drivers actually make mistakes
The mistakes don't happen on the open road, they happen in the quiet moments right before you join it. Pulling out of a petrol station, leaving an empty car park, or exiting a roundabout are the three places where drivers used to left-hand traffic sometimes drift back to old habits, simply because there's no surrounding traffic to correct them.
A simple fix: say "keep right" out loud as you pull away from any stop. Do it leaving the rental lot, leaving a fuel stop, and exiting every roundabout for the first day. It sounds basic, but it works, and most travellers report it becomes automatic well before the end of day one.
Roundabouts in particular are worth a mention, since Reykjavik and several other towns use them often. You give way to traffic already in the roundabout, signal your exit, and watch for cyclists and pedestrians at the crossing points. If you're arriving straight off a long flight and picking up your car at Keflavik, it can help to get your first roundabout attempt over with while you're still alert, a guide to picking up your rental at Keflavik Airport covers what that first stretch of driving typically looks like.
Rules of the road that matter more than which side you're on
Once you've settled into driving on the right, the details that actually shape your day-to-day driving in Iceland are less about sides and more about road behaviour that doesn't exist in the same form back home.
Headlights are required at all times, day and night, year-round. This isn't optional or weather-dependent, it's the law.
One-lane bridges are common on the Ring Road and on rural routes. The rule is simple: slow down early, and whichever car is closer to the bridge gets priority. There's no need to rush this, Iceland's road culture is patient rather than competitive.
Overtaking happens on the left, same as in any right-hand-traffic country, and only when the road ahead is clear and marked for passing.
Stopping on the shoulder of the Ring Road is discouraged and can be genuinely dangerous, traffic moves quickly, visibility is often limited, and the shoulder itself can be uneven or soft. If you want a photo, wait for a marked pull-off, viewpoint, or parking area. This matters more in Iceland than in many countries, because road markings and barriers are lighter than what drivers from busier road networks are used to, Icelanders simply don't stop on the Ring Road, so there's less signage warning you not to.
Sheep and other livestock roam freely near rural roads, especially in farming areas outside the main towns. Slow down when you see one animal near the road, because there are usually more nearby, and be ready for sudden movement.
If you want the fuller picture of road behaviour before your trip, gravel, elevated roads, weather shifts, the general guide to driving in Iceland covers those basics in more depth.
Does winter change which side you drive on?
No, the side of the road never changes with the season. What changes in winter is traction, visibility, and how quickly conditions shift, which raises the stakes of small mistakes rather than the driving rules themselves.
Wind is often the bigger factor in winter than ice. A clear morning on the south coast can turn windy or icy within a couple of hours, so it's worth checking road conditions at umferdin.is and weather at vedur.is before setting out, and building buffer time into your plan rather than a tight schedule. The winter driving guide goes through what changes behind the wheel between roughly November and April, and the winter safety guide for first-time visitors is worth a read if this is your first Icelandic winter trip.
Getting oriented before you leave Keflavik Airport
Most of the "which side of the road" anxiety actually happens in the first ten minutes after pickup, not later on the highway. Doing your online check-in in advance and collecting your car through key-box pickup (for customers who add the Liability Waiver and complete online check-in) at Keflavik means you can adjust your mirrors, set your navigation, and say your "keep right" reminder in a quiet car park rather than while merging into traffic. It's a small thing, but it removes one layer of pressure from a moment that's already a bit disorienting after a long flight.
If you're still deciding between a 2WD and a 4x4 for your route, that's a separate decision worth its own read, the 4x4 rental guide walks through when a smaller car is genuinely enough and when it isn't. And once you're in Reykjavik itself, parking works on a zone system that's worth understanding before your first night in the city, see the Reykjavik parking guide.
Mistakes to avoid in your first hour of driving
A few habits make the adjustment smoother, regardless of which side you drive on at home:
- Don't rely on other traffic to correct you. Empty car parks and quiet junctions are exactly where drift-back-to-old-habits happens, because there's no oncoming traffic to remind you which lane to take.
- Don't stop on the Ring Road shoulder for photos. Wait for a marked pull-off, it's safer and the photo will usually be better anyway.
- Don't assume gravel sections behave like paved roads. Reduce speed and increase following distance; loose stones and softer traction change how the car responds.
- Don't treat a single sheep sighting as a one-off. Where there's one, there are usually more nearby.
- Don't schedule your day with no buffer. Especially outside summer, weather can add time to a drive that looked simple on the map.
Conclusion: it's a smaller adjustment than it feels like from home
The worry behind this question is usually less about the rule itself, right-hand traffic is easy to state, and more about whether you'll actually manage it once you're tired, jet-lagged, and behind an unfamiliar wheel. In practice, the rule is simple and consistent everywhere in Iceland, and the real adjustment is a handful of habits around roundabouts, junctions, and quiet pull-outs that settle within the first day for almost everyone. Choose a vehicle that fits your route and season, take those first ten minutes slowly, and the rest of the drive tends to take care of itself.
