Iceland vs United Kingdom: Driving Rules Compared

Iceland simply doesn’t have motorways: the fastest legal speed anywhere on the ring road is 90 km/h, and gravel sections often run lower still. The UK, by contrast, drives on the left and allows 70 mph on a full motorway network. Add Iceland’s mandatory winter tyre season against the UK’s optional one, and this pairing has more differences than the numbers alone suggest.

Iceland drives on the right while the United Kingdom drives on the left. This is one of the most significant adjustments drivers must make when travelling between these two countries. Take extra care at junctions, roundabouts, and when overtaking.

Drivers in Iceland should observe limits of 50 km/h in built-up areas, 80 km/h on rural roads, and N/A on motorway stretches.

In United Kingdom, the standard speed limits are 48 km/h in urban areas, 96 km/h on rural roads, and 112 km/h (Speed limits in mph: 30 mph urban, 60 mph rural, 70 mph motorway) on motorways.

1. Respect local driving culture. Overtaking norms, horn usage, and right-of-way conventions differ. Observe local drivers and adapt accordingly.

2. Be aware of environmental zones. Many cities have low-emission zones that restrict older vehicles. Check if you need an environmental sticker for either country.

5. Adjust to speed limits immediately. When crossing the border, speed limits change. Look for signs and adjust your driving accordingly. Do not rely on habits from the other country.
