December road travel in Iceland can be brilliant, but only if you treat it as a winter drive rather than a normal island road trip. The combination of short daylight, sudden wind, black ice and fast-changing closures means the real challenge is making conservative decisions early. In this guide I cover what to expect, which car makes sense, how to plan a sensible route, and the habits that make self-driving realistic when conditions shift.
The key things to know before you start
- Short daylight is the biggest constraint. Around the winter solstice, Reykjavík gets only about four hours of usable daylight.
- A 4x4 helps, but it is not magic. It improves traction and confidence, yet it does not override closed roads or bad weather.
- Studded tyres are allowed in winter. In Iceland, that window runs from 1 November to 14 April.
- Route choice matters more than speed. In December, short day trips and flexible overnights usually work better than ambitious loops.
- Check conditions every day. Road status, wind and storm warnings can change the plan faster than you expect.
Why December changes the driving experience so much
In Iceland, December is not simply a colder version of summer. Light disappears early, roads that look damp can actually be glazed with ice, and winds can turn a manageable drive into a tiring one in minutes. Around the winter solstice, Reykjavík has only about four hours of daylight, and that short window is easy to lose if you start late or stop for too many detours.
Wind is the other big factor. Icelandic roads can look clear and then turn slick with ice, spray or blowing snow, especially on exposed coastal stretches and around mountain passes. I also treat a forecast of strong gusts as seriously as snowfall, because a tall vehicle or a light car can be pushed around far more than many first-time visitors expect.
December driving works best when the goal is control, not mileage. The moment you accept that, the rest of the trip becomes much easier to design.
Choose the right car and tyres
If I were hiring a car for winter, I would think in terms of margin for error, not just price. The vehicle does not need to be huge, but it does need to suit the roads you actually plan to use. That is especially true if you are arriving tired, driving after dark, or covering rural stretches where the weather can change faster than your plans.
| Option | Best for | Main drawback | My view |
|---|---|---|---|
| 2WD compact | Reykjavík, the Golden Circle, and short South Coast drives in settled weather | Less margin on ice, wind and slush | Acceptable only if your plan stays modest |
| 4x4 SUV | Winter roads, exposed stretches and extra confidence in changing conditions | Costs more and still needs caution | My default recommendation for December |
| Camper or motorhome | Very experienced winter drivers with highly flexible plans | Large side area catches wind, handling is slower | I would avoid it for a first winter trip |
| Guided transfer | Weather-sensitive days or routes you only want to see without driving | Less independence | Best fallback when conditions look poor |
Tyres matter just as much as the body style. Winter and summer tyres are allowed all year, while studded tyres are allowed from 1 November to 14 April. I always ask what is actually fitted, not what the booking page sounds like it should include. Before leaving the airport, I also check that the lights work, the washer fluid is topped up, the ice scraper is in the car and the phone is charged. That sounds basic, but basic is exactly what keeps a winter drive from becoming annoying.
Once the car is sorted, the route itself needs to be winter-shaped rather than summer-shaped.
Plan a winter-friendly route instead of a summer itinerary
I prefer a base-and-radii approach in December. Stay in Reykjavík or on the South Coast, then make short out-and-back drives instead of trying to "earn" the next town every day. The Ring Road is 1,322 km long, so it is a fine ambition on a flexible winter trip, but a poor choice if your dates are fixed and every overnight stop is non-negotiable.
- Golden Circle for the easiest classic loop.
- South Coast to Vík if the forecast is calm and daylight is on your side.
- Snæfellsnes only when you have a weather buffer.
- Highland F-roads should be off the table for a normal December self-drive.
The rule I use is simple: if the itinerary only works when the road behaves like summer, it is too optimistic for December. If you are tempted to pack too much in, the safest move is to trim the route now rather than force compromises later. Once the route is realistic, the next step is checking conditions properly before every departure.
Check road and weather conditions before every departure
My daily routine is to check the weather forecast and road status, then check them again before I actually start the engine. Icelandic conditions can change faster than your breakfast plans, and a road that looked passable earlier in the day can end up closed later on.
- Look at the full route, not just the final destination.
- Watch wind warnings, not only snowfall.
- Do not ignore a road marked closed.
- Leave room in the schedule to wait out a delay.
I also avoid leaving a town without enough fuel for the return leg plus a margin. In winter, that extra buffer matters because a minor detour, a delayed meal stop or a brief road closure can eat more time than you expect. If the forecast is marginal, I shorten the drive rather than hoping things improve en route. That habit is usually what separates a smooth winter day from a stressful one, and it leads directly into how you should actually drive once you are on the road.
Drive for ice, wind and darkness, not for the speed limit
On paper, Iceland’s common speed limits are 50 km/h in populated areas, 80 km/h on gravel roads and 90 km/h on paved rural roads, but those figures are maximums for good conditions, not targets. In December I often drive well below them, especially where the road looks shiny with ice or where the wind is crosswise.
I also keep the car calm. I brake earlier, accelerate gently and leave far more space than I would in summer. On ice, abrupt steering is usually the mistake that starts the slide, not the slide itself. When visibility drops, I would rather arrive ten minutes later than fight the wheel for half an hour.
- Keep headlights on at all times and keep the phone out of your hand.
- Slow down well before bends, crests and single-lane bridges.
- Expect livestock on rural roads and treat blind rises with caution.
- Do not stop on the roadside unless there is a genuinely safe pull-off.
- If the wind starts pushing the vehicle or the road feels tiring, turn back early.
There is also one distinctly Icelandic habit that matters: if a road is closed, the closure is not a suggestion. It is a hard stop. That discipline becomes even more important once you start carrying extra layers, food and other winter basics for delays.
Pack for delays and know when to stop
Even on a short December drive, I would keep a small winter kit in the car. It does not need to be theatrical; it just needs to let you wait, warm up and make a sensible decision if the weather changes while you are between towns.
- Warm layers, gloves, hat and waterproof outerwear.
- Water and high-energy snacks.
- Charged phone plus power bank and cable.
- Ice scraper, de-icer and a torch.
- Blanket or extra fleece for longer crossings.
- Enough fuel for the return leg plus a margin.
If you get into real trouble, call 112. If you are merely delayed, the better move is usually to wait somewhere safe rather than chase the schedule. And one thing I would never do in winter is leave the road for a shortcut; off-road driving is illegal and the penalties can be severe. That caution is not overkill in Iceland, where the landscape is beautiful but easy to damage and the weather can change the road faster than the map can.
The December driving plan I would actually use
For most travellers, the best December plan is not the biggest one. It is a short route, a capable car, a flexible overnight schedule and the discipline to cancel one leg when the weather says no. That approach gives you a much better chance of enjoying Iceland instead of just surviving the drive.
- Base yourself in one or two places.
- Keep each driving day short.
- Choose a car that matches winter roads, not just the cheapest class.
- Use the weather forecast and road-status map as part of the itinerary, not as an afterthought.
If I were planning a first winter trip, I would rather see a smaller part of Iceland well than rush a full loop and spend half the holiday watching the forecast. December rewards patience, and on Iceland’s roads that is usually the smartest form of safety.
