Iceland Driving Rules for Americans (2026 Complete Guide)
Iceland drives on the right, same as the US. Speed limits top out at 90 km/h (56 mph), headlights must be on 24/7 by law, and off-road driving is a serious offense. A US license is accepted on its own — an IDP is not required, but is a handy translation backup.

Which Side of the Road Does Iceland Drive On?
Iceland drives on the right-hand side of the road, exactly like the United States, and cars are left-hand drive. This makes Iceland an easy adjustment for Americans compared with the UK or Ireland — the challenge in Iceland is never which side, it is the weather, the surface, and the isolation.
Roundabouts turn counter-clockwise, and traffic already in the circle has priority. On Reykjavík's two-lane roundabouts, the inner lane generally has right of way when exiting — watch the lane arrows painted on the road.
Iceland Speed Limits
Iceland's limits are low by American standards — the maximum anywhere is 90 km/h (about 56 mph). Crucially, the limit drops on unpaved roads even where no new sign appears.
| Road Type | Limit (km/h) | Approx (mph) |
|---|---|---|
| Urban / built-up areas | 50 | 31 |
| Residential zones | 30 | 19 |
| Rural gravel/unpaved roads | 80 | 50 |
| Rural paved roads (incl. Route 1) | 90 | 56 |
There are no true highways or Autobahn-style motorways in Iceland — 90 km/h is the ceiling on the open Ring Road. On gravel the limit is 80 km/h, but you should often drive well under that for safety.
Police and Speed Enforcement
The national police force is Lögreglan. Enforcement is a mix of fixed speed cameras, mobile radar, and patrols, concentrated near Reykjavík, on approaches to towns, and in tunnels.
- Fixed cameras: Positioned on the Ring Road, in the Hvalfjörður tunnel, and near populated areas. They photograph front plates.
- Mobile radar: Lögreglan run unmarked and marked patrols; Iceland is small, and word of a speeding foreign rental travels.
- Tolerance is minimal. Do not expect the generous cushion some US states allow — assume the posted number is the number.
Camera and patrol fines are issued to the registered keeper — for a rental, that means the fine reaches the rental company, who forward it to you with an admin fee. See our Iceland driving fines guide for amounts.
Drinking and Driving: Iceland's BAC Limit
Iceland enforces a strict blood-alcohol limit of 0.05% (0.5 g/L) — lower than the 0.08% standard across most US states. In practice, this means even one drink can put you over.
- 0.05% and above: Heavy fines (often ISK 100,000+ / ~$700+) and license suspension.
- Higher readings: Larger fines, longer bans, and potential criminal proceedings.
- The safe rule: Do not drink at all if you are driving. Icelanders treat this as normal; it is the accepted local standard.
Roadside breath testing is routine at checkpoints, especially around holidays and in Reykjavík nightlife areas.
Mandatory Equipment and Behavior
- Headlights on 24/7: Iceland law requires dipped headlights day and night, all year. This is the rule Americans most often break out of habit. Most rentals default to auto — confirm.
- Seat belts: Mandatory for all occupants, front and rear. Fines apply per unbelted passenger.
- Child seats: Required for young children by age/height; arrange with your rental in advance.
- Winter tires: Studded or winter tires are required in the colder months (roughly November to mid-April) and strongly advised for any winter driving.
- Warning triangle: Should be carried in the vehicle; most rentals include one.
Off-road driving is illegal: Driving off marked roads or tracks — onto moss, lava fields, or beaches — is a serious environmental offense in Iceland with fines that can reach hundreds of thousands of ISK. Stay on the road, always.
Mobile Phone Use
Handheld phone use while driving is prohibited. You may use a phone only via a hands-free mount or Bluetooth. Fines for handheld use start around ISK 40,000 (~$285).
Because Iceland relies heavily on GPS navigation between sights, set your route before you move and mount the phone. Never hold it to read directions on a gravel road.
Icelandic Road Signs Americans Should Know
Iceland uses European-style signs, mostly pictograms, but a few use Icelandic words that are worth memorizing:
| Sign / Word | Meaning |
|---|---|
| Stop (red octagon) | Stop — same shape as the US |
| Einbreið brú | Single-lane bridge ahead — yield |
| Malbik endar | Paved road ends (gravel begins) |
| Blindhæð | Blind hill / blind rise — slow down |
| F + number (e.g. F26) | Mountain F-road — 4WD legally required |
| Vegurinn lokaður | Road closed |
| Aðrein | Merge / on-ramp |
Right-of-Way Conventions
- Single-lane bridges: Whichever car reaches the bridge first has priority. Slow down early and be ready to yield — never race an oncoming car to the bridge.
- Roundabouts: Traffic already in the roundabout has right of way. In two-lane roundabouts, follow the painted lane arrows.
- Unmarked intersections: Yield to traffic coming from your right unless signs say otherwise.
- Pedestrians: Yield at marked crossings; Reykjavík enforces this.
- Livestock: Sheep have no right of way, but hitting one makes you liable to the farmer — slow and give them room.
Gravel Roads and F-Roads
Outside the paved Ring Road and Golden Circle, much of Iceland is gravel. This changes how you drive and what is legal:
- Speed drops to 80 km/h on gravel — and you should often go slower. Braking distances are much longer on loose surface.
- Slow down for oncoming cars to reduce thrown gravel that chips windshields (a very common rental claim).
- Where pavement ends (Malbik endar sign), the transition can be sudden and slick — ease off before you reach it.
- F-roads require a 4WD by law. Entering an F-road (F26, F35, etc.) in a 2WD voids your rental insurance instantly and is unsafe. Many F-roads also include unbridged river crossings, which no insurance covers.
- F-roads are seasonal. They open only when conditions allow, typically mid-June to September, and can close again without notice.
Iceland-Specific Driving Quirks
- Wind is a driving hazard, not just weather. Gusts can push a car across a lane or slam a door hard enough to damage it (and door/wind damage is not insured). In extreme wind warnings, pull over and wait.
- Blind hills (Blindhæð). Rural roads roll over crests where you cannot see oncoming traffic. Keep right and slow near the top — some are single-lane at the crest.
- Weather changes by the hour. Sun, sleet, fog, and whiteout can all happen in one drive. Check road.is and vedur.is every morning before setting off.
- Tunnels can be tolled or single-lane. Some tunnels (e.g., in the Westfjords) are one lane with pullouts; the car nearest a pullout yields. The Vaðlaheiði tunnel near Akureyri is tolled online.
- Fuel stations thin out. Outside towns, gaps between stations can be long. Refuel at half a tank, and carry a PIN-enabled card since pumps are often unattended.

Get Your IDP for Iceland Today
An IDP costs $20 and takes 1–2 weeks by mail. It is not legally required in Iceland — but as a multi-language translation of your license, it is cheap reassurance for rural stops and rental counters.
