Driving in Iceland
Most mountain roads and roads in the interior of Iceland have a surface of loose gravel. The same applies to some sections of the national highway, which also has long stretches of asphalt. The surface on the gravel roads is often loose, especially along the sides of the roads, so one should drive carefully and slow down whenever approaching an oncoming car. The mountain roads are also often very narrow, and are not made for speeding. The same goes for many bridges, which are only wide enough for one car at a time. In addition to not having an asphalt surface, the mountain roads are often very winding. Journeys therefore often take longer than might be expected. The total length of the Ring Road around Iceland (national highway) is 1.339 km.
The general speed limit is 50 km/h in urban areas, 80 km/h on gravel roads in rural areas, and 90 km/h on asphalt roads.
Special warning signs indicate danger ahead, such as sharp bends, but there is generally not a separate sign to reduce speed. Please choose a safe speed according to conditions. Motorists are obliged by law to use headlights at all times day and night. In Iceland all driving off roads or marked tracks is prohibited by law. Passengers in the front and backseats of an automobile are required by law to use safety-belts. Icelandic law forbids any driving under the influence of alcohol.
