Iceland road conditions: how to check, read, and respond
Seljalandsfoss: South Coast classic full day
How do I check road conditions in Iceland?
Use road.is (Vegagerðin) — Iceland's official road administration website. The map colours roads by their state (passable, slippery, difficult, impassable, closed); the legend shown on the official map gives the exact meaning of each colour, so read it every time. Check every morning before driving, not just at the start of the trip.
Road.is: the system you need to understand
Road.is is the public-facing interface of Vegagerðin, Iceland’s Road and Coastal Administration. It is not a third-party app or travel site — it is the government’s own road monitoring system, updated directly by road patrol crews and automated sensors.
The primary view at road.is/en shows an interactive map of Iceland with every numbered road coloured by current conditions. The same information is available on vegagerdin.is in Icelandic with more operational detail.

Colour codes explained
The map colours each road according to its state: passable, slippery, difficult, impassable or closed. The legend displayed on the official map of Vegagerðin gives the exact meaning of each colour — read it every time you open the map, and do not rely on a colour-to-meaning chart from memory.
Passable
Road is passable without special precautions for appropriately equipped vehicles. In winter, a passable road still means you should check weather forecasts — conditions can change within hours.
Slippery
Specific hazard conditions are present: icy surface, poor visibility, high winds, or wet roads with reduced traction. Reduce speed, increase following distance, and be prepared to stop or turn around. Most winter days in Iceland include several slippery segments on the Ring Road.
Difficult
Significant hazards present that require winter driving experience and a capable vehicle. Amateur winter drivers should consider waiting. If driving, slow down and give it full attention. Common conditions: packed snow, ice on curves, drifting snow, severe crosswinds. If you don’t have winter driving experience, this is the point to reconsider self-driving altogether — see self-drive vs guided tour for how to weigh that decision honestly.
Impassable
The road is effectively closed by conditions even if not formally shut. You could physically enter the road but would likely not make it through safely. Treat impassable segments as closed.
Closed
Vegagerðin has closed the road. If the official site shows a closed road, do not enter it. Closed roads do not open again until crews have cleared and assessed the route.
Travel notes: the written descriptions
Alongside the colour map, road.is publishes text descriptions for specific road segments with current conditions. Examples:
“Route 1 on the South Coast: icy surface in low areas, drive with caution.”
“Route 92 Eastfjords pass: reduced visibility due to blowing snow, difficult conditions. Only experienced drivers.”
“F26 Sprengisandur: closed. No date for opening.”
These notes give context that colour alone cannot. Check both the map and the travel notes for your planned route. If you are new to the roads themselves, our driving in Iceland guide covers the rules and habits that make these notes easier to act on.
How conditions change through the day
Morning: Road crews begin clearing and gritting at 07:00–08:00. Conditions are often at their worst overnight (no treatment) but improve through the morning. The most dangerous period is often dawn — temperatures at minimum, ice on untreated surfaces.
Afternoon: Glacier melt increases water flow over roads near Vatnajökull and Mýrdalsjökull. Some highland sections that were passable in the morning become risky by 14:00–16:00 due to water on the road.
Evening: Temperatures drop again. Ice reforms on untreated sections. The period 22:00–06:00 is highest risk for black ice on roads that warmed slightly during the day.
Check road.is before you start driving each day, not once at the start of your trip. A clear status on Monday says nothing about conditions on Thursday. For the wider picture of how the seasons shape these daily swings, see Iceland weather explained and our winter driving guide.
The 112.is Iceland app
Separate from road.is, the 112 Iceland app is the official emergency response application:
- Allows you to submit your travel plan — rescuers know where to look if you don’t return
- Sends your GPS location to emergency services with one button press
- Works on cellular data and also sends location via SMS if data fails
- Free download on iOS and Android
Every Iceland traveler driving outside Reykjavik should have this app installed with location permissions enabled. Safetravel.is (accessible via the app) is the travel plan registration system. Our safetravel and emergency info guide covers registration and emergency numbers in more depth.
Weather forecasts and road condition interaction
Road conditions follow weather — you need both sources:
Vedur.is (Icelandic Meteorological Office): Hourly forecasts per location. Wind speed, precipitation, temperature, visibility. The wind map is particularly useful — it shows gust strength for every region, which affects driving decisions more than temperature in Iceland.
The combination workflow:
- Check vedur.is the evening before for forecast
- Check road.is first thing in the morning for actual current conditions
- Revise your plan based on both
If vedur.is shows an approaching storm system, check the road.is status for your route in the morning — by then, night patrols have reported and the colour map is updated.
Common closure scenarios and what to do
South Coast (Mýrdalssandur / Skeiðarársandur sand plains)
The black sand outwash plains near Vík are the most frequently closed section of the Ring Road. Wind speeds of 25+ m/s can create complete zero-visibility sandstorms that damage vehicles and make the road impassable.
What to do: If Vík direction is closed, wait in Reykjavik or Selfoss. Book accommodation flexibly. The closure will lift when the wind drops — check road.is regularly during the event. If your itinerary has slack, our south coast day trip guide has a realistic backup plan for waiting out a closure without wasting the day.
South Coast classic full-day tour from ReykjavíkLetting a local guide handle a marginal-conditions day is a legitimate alternative to self-driving through difficult or impassable road segments, and it removes the decision-making burden entirely.
Eastfjords mountain passes
The passes on Route 1 through the Eastfjords (Breiðdalsheiði, Fjarðarheiði) can close in winter snowfall. Alternative routes exist (coastal byways) but add 30–50 km.
What to do: If the pass closes, take the Route 96 or Route 95 coastal alternative. Less dramatic driving but avoids the closure.
Northern mountain roads
Route 1 between Akureyri and Egilsstaðir crosses elevated terrain that catches snow earlier than the coast. Closures here are less common in summer but can trap vehicles in October–November.
What to do: If your timing is October–November, have accommodation in Akureyri or Egilsstaðir available for an extra night. Closures here rarely last more than 24 hours.
F-road closures
F-roads are closed in winter; the opening dates vary every year, so consult the official Vegagerðin website. Mid-season closures happen if summer storms bring flooding or snow to the highlands. See F-roads in Iceland and 2WD vs 4x4 in Iceland for which vehicle and route combinations are realistic even when a highland road is technically open.
What to do: Do not attempt a closed F-road. No exception, no workaround.
If a highland route is off the table, the highlands destination page and our Landmannalaugar hiking guide help you decide what to swap in, and a super jeep tour is the usual way to reach the interior without driving it yourself.
Road.is webcams: real-time visual conditions
Beyond the colour-coded map, road.is hosts a network of roadside webcams on major routes. These provide actual visual confirmation of conditions:
What webcams show well: Active snowfall intensity, current visibility (whether fog is clearing or settling), actual state of road surface (ice vs clear). If the map flags a stretch as slippery and the webcam shows clear tarmac, you can drive with more confidence. If the webcam shows a whiteout, the colour coding may actually be understating the danger.
Webcam locations on the Ring Road: Coverage is good on the South Coast and near Reykjavik. The East Fjords passes have one or two cameras but the network is thinner in remote areas.
Accessing webcams: At road.is, click any road segment and the sidebar shows linked webcam feeds. The English-language version includes these.
Seasonal road condition patterns
South Coast (Reykjavik to Höfn)
Summer (June–August): Generally passable. Storm-related closures at Mýrdalssandur near Vík can still happen.
September–October: Mostly passable with occasional slippery days when early autumn storms arrive. First ice events on bridges in late October.
November–March: Regular slippery and difficult conditions. Mýrdalssandur closures increase significantly. The South Coast is more reliable than the East in winter but not reliably clear. If you are planning that stretch, our South Coast itinerary and the Vík destination page show where a closure leaves you with useful things to do nearby.
East Fjords (Höfn to Egilsstaðir)
Summer: Generally passable. Some gravel track sections near viewpoints.
October–November: Mountain passes (Breiðdalsheiði, Fjarðarheiði) can get their first snowfall. These passes close when conditions become difficult or impassable.
December–March: The most volatile Ring Road segment in winter. Pass closures happen regularly; the coastal alternative (Route 96, Route 95) adds distance but avoids mountain passes.
North Iceland (Akureyri area)
Summer: Generally passable. Route 1 is straightforward.
October–April: Route 1 crosses elevated terrain between Akureyri and Egilsstaðir. The Múlasýsla section and Route 1 near Öxnadalsheidi get significant snowfall. Slippery and difficult conditions are common from November.
Snæfellsnes Peninsula (Route 54/574)
The mountain roads on Snæfellsnes, particularly Route 570 across the glacier approaches, can close or deteriorate significantly from November. The coastal route (Route 574) is more reliable in winter but still subject to wind and ice at exposed headland sections. If the weather looks marginal, a private guided day on the peninsula lets someone who knows these roads decide when to push on and when to turn back.
After a road opens: the first hour
When a road reopens after a closure, the first while before road crews have finished is often the most dangerous. Ice may still be present on the road surface; road debris (sand, gravel, storm damage) has not been cleared; road crews may still be working.
Wait a little after a road shows “reopened” on road.is before committing to that route. Use the time to check the webcam (if available) and fuel up. Let a few other vehicles go first if possible.
Safetravel.is: the parallel system
Alongside road.is, safetravel.is is Iceland’s official safety and travel plan registration system operated by the Icelandic Association for Search and Rescue (ICE-SAR).
Travel plan registration: You submit your planned route, vehicle description, number of people in the party, and expected return time. If you don’t confirm your safe return, rescuers are notified and begin following up. This system has directly led to faster rescues when things went wrong.
How to register: Go to safetravel.is and create a travel plan. It takes 5 minutes. Alternatively, the 112.is Iceland app allows you to register plans from your phone. Both systems share data with emergency services.
When to register: Any time you are driving outside the Reykjavik metropolitan area — especially before entering the East Fjords, Westfjords, or any highland route. For Ring Road travel, register the whole trip at the start and update if your plans change significantly.
Real examples of Ring Road closures and their impact
Understanding how closures actually play out helps you plan realistic responses:
Mýrdalssandur closure (typical): Wind picks up to 28–35 m/s by 14:00 on a Tuesday. Road.is shows the stretch from Vík to Kirkjubæjarklaustur worsening through the afternoon until it is officially closed. Travelers heading east out of Vík are stuck in town. The closure lifts once the wind system passes. During the closure, N1 in Vík fills with stranded rental cars.
What to do in this scenario: Accept it gracefully. Vík has accommodation, a grocery store, and the Reynisfjara black sand beach is still accessible from the Vík side during many (not all) closures. Check road.is regularly. Have the next night’s accommodation on a flexible cancellation. When the road reopens, leave promptly — it’s often briefly open before the next weather front.
Eastfjords pass closure (typical): November snowfall arrives overnight, closing the Breiðdalsheiði pass from around 07:00. Road.is shows the pass as closed. The Route 96 coastal alternative is open (adds 30 km). Most travelers who check road.is before departure take the coastal route without issue. Travelers who don’t check drive all the way up to the pass closure sign.
Interpreting road.is for specific situations
Scenario: You want to drive from Reykjavik to Vík today
Check Road 1 segment from Hveragerði to Vík. If passable: straightforward. If slippery: drive at reduced speed, watch for ice on bridges. If difficult: consider whether you have winter driving experience; if not, consider postponing. If impassable or closed: don’t go. The road will reopen; your schedule needs to adapt.
Scenario: You are in Akureyri and want to drive to Mývatn via Route 1
The stretch from Akureyri east on Route 1 passes highland terrain. Check the specific segment on Route 1. Even in summer, this section can have difficult conditions in June from late snow or fog. Look at the webcam if available.
Scenario: You want to drive Route 550 to Kerlingarfjöll
Route 550 is an F-road. Check on the official map whether it is open or closed. If closed, no debate. If open but it’s mid-June, double-check the Kerlingarfjöll resort website — they sometimes open later than the official road opening.
Emergency contact numbers for drivers
Keep these readily accessible:
- 112: Iceland emergency services (police, fire, ambulance, ICE-SAR). Use for genuine emergencies — vehicle off road, medical emergency, person missing.
- Road.is emergency info: Not a phone number but check the travel notes section for active road emergency reports
- Your rental company: Emergency line is on the rental agreement. Keep it in your phone contacts before driving
- Icelandic Road Administration (Vegagerðin): +354 522 1000 — for road condition information in Icelandic (or basic English)
Iceland’s 112 app also connects to ICE-SAR directly with GPS and is more reliable than calling 112 in areas with poor voice signal.
Reading conditions by region: a quick reference
Beyond the live colour map, it helps to know which regions are structurally more volatile than others before you plan a route:
| Region | Volatility (winter) | Typical closure trigger |
|---|---|---|
| South Coast (Mýrdalssandur) | Moderate | High wind, sandstorms |
| East Fjords passes | High | Snowfall, low visibility |
| North (Akureyri–Egilsstaðir) | High | Early snow, elevated terrain |
| Snæfellsnes mountain roads | Moderate | Snow, wind at headlands |
| Westfjords | High | Snow, narrow roads, limited alternatives |
| Reykjavík–Golden Circle | Low | Rare; mostly low-elevation, well-treated |
If your itinerary is tight on time, weighting your route toward the lower-volatility regions (South Coast core, Golden Circle) reduces the odds of losing a full day to a closure. See the Ring Road guide for how to sequence a full circuit around these risk patterns, and ring road clockwise or counterclockwise for how direction of travel interacts with seasonal weather patterns.
This is also why a 10-day-plus Ring Road itinerary is meaningfully more resilient to weather than a tight 5–6 day version: it has more natural slack to absorb a closure without forcing a missed flight or a cancelled non-refundable booking. Travellers who would rather not make the closure calls themselves can also consider a guided circuit of the Ring Road, where the guide watches the road status and reshuffles the days as conditions demand. If your dates are fixed and short, build the highest-volatility regions (East Fjords, Westfjords, North) into the middle of the trip rather than the final days, so a closure has room to resolve before you need to reach the airport.
Frequently asked questions about Iceland road conditions
How often do Ring Road sections close in summer?
In June–August, Route 1 closures are rare. The Mýrdalssandur section near Vík is the most likely. September closures increase. October onwards: meaningful closure probability on the East and North sections.
Can I get a refund on accommodation if I can’t reach it due to road closures?
Most guesthouses and campsites in Iceland have pragmatic policies about force majeure road closures — contact them directly and explain the situation. Booking platforms (Booking.com, Airbnb) have their own force majeure policies. Travel insurance with trip interruption cover is worth having specifically for this scenario; see travel insurance for Iceland and car rental insurance in Iceland for what is worth covering.
Are road closures communicated on social media?
Vegagerðin has an active Facebook page and posts major closure updates in Icelandic. A quick translation is usually sufficient. Some local radio stations (Rás 1, Bylgjan) broadcast road closure news in Icelandic during peak storm events.
Does Google Maps update with road closures?
Sometimes, with a lag. Google Maps does not directly integrate with road.is in real time — it sometimes shows closed roads as open for several hours after closure. Always check road.is directly rather than relying on navigation apps for closure status.
What if I’m already on a road when it’s closed?
Turn around. If you are past a closure point and cannot safely turn around, call 112 for guidance. Emergency vehicles will not enter a closed road for a non-emergency — this is not like a mainland motorway closure where diversion is managed.
What time does road.is update?
The road condition map updates continuously throughout the day based on sensor data and road patrol reports. Major updates come from patrol crews who are on the roads from the early morning. The travel notes section is updated manually by road crews reporting conditions — significant changes in conditions (a road closing or opening) appear in the travel notes after crews confirm the situation.
Is there an English version of road.is?
Yes. Road.is has an English-language interface accessible from the language toggle at the top right of the website. All colour coding, travel notes, and webcam views are available in English.
How do I report a road hazard in Iceland?
Call 112 for a hazard requiring immediate emergency response (vehicle in ditch, accident, person injured). For non-emergency road hazards (large debris on road, damaged sign, pothole), call Vegagerðin at +354 522 1000 during office hours. The road patrol crews are also reachable through the road.is system. If in doubt, call 112 — the operators will direct your call appropriately.
Should I just book a guided tour instead of self-driving in winter?
If you have no winter or ice driving experience, it’s a reasonable choice for the riskiest segments (South Coast in a storm, East Fjords passes). Many travellers self-drive the low-volatility sections (Golden Circle, Reykjavík day trips) and book a guided day for the higher-risk stretches. See self-drive vs guided tour for a fuller comparison.
Does road.is cover gravel and F-roads the same way as paved roads?
Yes — F-roads and gravel roads are shown on the same map, but they’re inherently more volatile and close earlier in autumn and open later in spring than paved roads. Treat an open F-road with more caution than an open paved road, and always check the specific F-road status separately rather than assuming the whole highland network is open together.
