Safe Driving in Iceland: 10 Rules Every Traveler Should Know

Practice safe driving in Iceland with the 10 rules every visitor should know. This guide covers the wind, gravel, single-lane bridges, roaming sheep, and winter ice that catch drivers out. Read on to learn how to stay safe behind the wheel.

Driving is one of the best ways to see Iceland, and rental cars open up every corner of the country at your own pace. The catch is that the roads here behave differently from the ones you know at home.

The weather in Iceland can turn in minutes, the wind can rip a car door off its hinges, and a sheep can appear in front of you on an empty road. None of that should put you off. It just means a little know-how goes a long way, and it is worth having before self-drive tours that keep you moving every day.

These are the 10 rules that matter most when driving in Iceland. Read them before you set off, and you will handle almost anything Iceland’s roads throw at you.

Key Takeaways

• Check road conditions and weather before every drive at umferdin.is, en.vedur.is, and safetravel.is. Conditions change fast.

• Wind is the hazard visitors underestimate most. Hold your door when opening it, and think twice about driving in strong gusts or a sandstorm.

• Never stop on the road for photos. Use the marked pullouts and parking areas.

• Slow right down for gravel, especially where asphalt turns to gravel.

• At a single-lane bridge, the car closest to it goes first.

• Sheep roam free between May and October, and you are liable if you hit one.

• F-roads need a 4x4 vehicle, open only in summer, and river crossings are never covered by insurance.

• Off-road driving is illegal everywhere and heavily fined.

• Headlights stay on day and night, everyone wears a seatbelt, and the drink-drive limit is effectively zero.

• The emergency number is 112.

At a Glance: The 10 Rules for Driving Safely in Iceland

Here is the whole checklist in one view before we get into the detail.

1. Check the Conditions Before Every Drive

Before you turn the key and drive off for the day's adventures in Iceland, always check the local conditions and forecasts. This is the single habit that prevents the most trouble, because a road that was clear yesterday can be closed, icy, or wind-battered today.

Check live road conditions and closures at umferdin.is (or call 1777), the weather and wind forecast at vedur.is, and any active alerts at safetravel.is, where you can also leave a travel plan. Do not trust Google Maps alone, as it often fails to tell you about roads that are shut or impassable.

While you are at it, plan your fuel. Distances between gas stations can be long in the east and the Highlands, so fill up whenever you get the chance rather than waiting for the gauge to drop.

Most stations are self-service and unmanned, and the pumps need a card with a four-digit PIN. Many US cards run on chip-and-signature and get declined at the pump, so bring a PIN-enabled card or buy a prepaid fuel card inside a staffed N1 or Olis station. Additionally, check whether your car takes petrol or diesel before you fill up, since misfueling is a costly mistake.

One last thing. If you have just landed off an overnight flight, rest before you drive. Jet-lagged driving causes real accidents here, and the scenery is not going anywhere.

2. Respect the Wind

Wind is the hazard tourists underestimate most, and it does more damage in Iceland than ice. Gusts can slam a car door hard enough to bend the hinges, or push a moving car across the road.

Always hold the door firmly when you open it, and park with the front of the car facing into the wind. Keep an eye on wind warnings, and treat gusts above roughly 15 to 20 meters per second as a reason to slow down or wait. If you hit a sandstorm or ash storm, find a safe place to stop, keep the doors and windows shut, and let it pass.

Even in summer, the wind can cause troubling conditions. For example, in July 2026, on two separate occasions and in different regions of the country, a caravan was flipped over due to the wind and a trailer was blown off the road. It's also reported that travelers who ignore weather warnings may receive limited compensation from their insurance.

One more reason to take wind seriously: door damage and paint stripped by wind-blown sand are usually not covered by standard rental insurance, so the bill lands on you.

3. Never Stop on the Road

Do not stop your car on the road or the shoulder to take a photo, no matter how tempting the views are or how cute the Icelandic horses look. Sudden roadside stops are one of the most common causes of accidents involving visitors, because the driver behind you is not expecting it.

Iceland makes this easy to avoid. Marked pullouts and parking areas appear roughly every few kilometers along the main routes, and every major attraction has its own parking lot. Signal, pull fully off the road, and never reverse on the highway to get back to something you passed.

You also don't need to stop roadside to see the northern lights in Iceland. Check out the top viewing spots in Reykjavik in advance or drive out to places with little light pollution such as Thingvellir National Park or Kleifarvatn Lake, less than an hour's drive from the capital. If you're already based outside of Reykjavik, it should be relatively easy to find a dark area.

4. Slow Down for Gravel

Large stretches of the Ring Road and almost every rural route turn to gravel, and the most dangerous moment is the point where asphalt ends and gravel begins. Slow down before you reach it, not after, because tires lose grip fast on the loose surface and it is easy to lose control.

The edges of gravel roads are especially loose, so keep to the firmer middle where it is safe and ease off well before an oncoming car. Slow right down when you pass, as flying stones chip windshields and headlights. That kind of damage is often excluded from basic cover too, which is why rental companies offer gravel protection.

5. Yield Correctly at Single-Lane Bridges, Tunnels, and Blind Hills

Iceland has hundreds of single-lane bridges, and the rule is simple. The car closest to the bridge has priority. If the other vehicle will clearly reach it first, stop in a safe spot and wait rather than racing for it.

Some tunnels, mainly in the Westfjords and North Iceland, are also single-lane with marked passing places, and the signs tell you who gives way. Take your sunglasses off before you enter any tunnel so the sudden darkness does not blind you. It helps to learn Iceland’s road signs before you go, since a few warn of hazards you will not see in time otherwise.

Blind hills, marked “blindhaed,” and blind bends work on the same logic. You cannot see oncoming traffic until you reach the crest, so slow down and keep well to the right.

6. Watch for Animals

Sheep graze freely across Iceland between May and October, and they wander onto roads without warning. A ewe will often bolt across to reach a lamb on the other side, so if you see one sheep near the road, expect a second to run in front of you. Slow down and be ready to stop.

If you do hit livestock, you are legally responsible. You must report it, contact the nearest farm to find the owner, and you will be liable for compensation. Call 112 if anyone is hurt or you need help. Watch for reindeer in the east and low-flying birds as well.

7. F-Roads Need a 4x4, and River Crossings Need Real Care

Mountain roads marked with an “F” (such as F35 or F208) lead into the Highlands, and by law you must drive them in proper 4x4 vehicles. A two-wheel-drive car is both illegal on these roads and simply not capable of them.

These are seasonal routes. They open only in summer, usually in mid-June once the Icelandic Road Administration clears them, and close again in autumn. Check the current opening dates and route details in our guide to Iceland’s mountain roads before you plan a Highlands trip.

Many F-roads include unbridged river crossings, and this is where people get into expensive trouble. No insurance in Iceland covers water damage, ever, so a flooded engine is entirely on you. If you are not confident reading a river, do not cross. Watch a local vehicle go first, cross at the widest and shallowest point, and drive slow and steady in low gear.
