1. Roundabouts? Let the Inner Circle Pass First

In Iceland, unlike many countries, the inner lane in two-lane roundabouts always has priority. That means if you're merging or switching lanes, yield to traffic already circulating inside—even if you plan to exit soon.

‍

2. Speed Limits—What to Know

• Urban areas: 30–50 km/h
• Gravel rural roads: 80 km/h
• Paved highways (Route 1, etc.): 90 km/h
  Always slow down on gravel, especially where sheep or road debris might appear.

3. Iceland’s Only Toll Road—The Vaðlaheiði Tunnel

The lone toll tunnel, Vaðlaheiðargöng, bypasses the icy mountain pass near Akureyri. It costs around 1,500–2,500 ISK per passage, payable online within 24 hours—drivers who don't pay are billed via their rental agency (plus service fees). Alternatively, the old mountain route is scenic and toll-free in good weather.

4. One-Lane Bridges & Sheep Traffic

Single-lane bridges are common on Iceland’s rural roads—priority to the vehicle that arrives first. Be extra cautious on approaches, particularly in inclement weather. Also, watch for “ninja sheep,” which can dart onto the road unexpectedly. If you hit a sheep, note that you may be liable for farmer’s compensation.

5. F-Roads: Only in Summer and Only for 4×4’s

F-roads are highland tracks featuring gravel, river crossings, and rough terrain. Typically open late June to early September, only vehicles with 4×4 approval—often “super jeeps”—can traverse them. Driving in a 2WD vehicle is illegal and dangerous—and voids insurance. Always check road.is for road closures.

6. Headlights & Onboard Essentials

• Headlights must be on at all times, day and night—‘Auto’ setting often doesn’t activate tail lights.‍
• Required in-car equipment:
  • Headlamp converters (for right-side driving).
  • Warning triangle.
  • Recommended: first-aid kit, reflective jacket, spare bulbs, and fire extinguisher.

Insider Tip: Always check road.is for road status, vedur.is for weather updates, and file a travel plan via Safetravel.is before venturing into highlands or remote areas. ‍

Stay safe, drive sensibly, and enjoy Iceland’s incredible road trips—without unexpected fines or frozen engines.
