Driving in Norway: Speed Limits, Tunnels, Ferries and Wildlife — the Practical Guide

The basic rule always surprises visitors: outside built-up areas, the default speed limit is 80 km/h, and 50 km/h in towns. Only a few motorways around Oslo go up to 100 or 110 km/h. On fjord roads, posted limits often drop to 60 or even 50 km/h through bends and hamlets — and they should be taken seriously: Norwegian fines are among the highest in Europe, running to several hundred euros for even a moderate offence, with licence confiscation possible for serious speeding.

Enforcement is largely automated: fixed speed cameras ('fotoboks', announced by signs) and average-speed sections that measure your speed between two gantries, notably in tunnels. Another absolute rule: dipped headlights (or daytime running lights) must stay on at all times, day and night, all year round. Finally, the blood alcohol limit is 0.02% — effectively zero: a single drink is enough to exceed it, and penalties apply from the first offence.

Here is a summary of what changes compared with driving in most of Europe.

Norway has more than a thousand road tunnels, from 200-metre cuttings to the Lærdal Tunnel, the longest road tunnel in the world at 24.5 km between Aurland and Lærdal. Some are spectacular: subsea tunnels that plunge steeply under a fjord before climbing back up the other side, spiral tunnels, and even roundabouts carved into the rock where two galleries meet. Most are lit and well maintained, but the older, narrower and darker ones demand a real reduction in speed.

One point deserves particular attention: the entrance. A study by Finn Harald Amundsen and Guro Ranes covering nearly 600 Norwegian road tunnels, published in 2000 in the journal Tunnelling and Underground Space Technology, shows that accident rates are markedly higher in the entrance zone of tunnels than in their interior sections — the abrupt transition from daylight to darkness and the trajectory adjustment play a large part (study on Google Scholar: scholar.google.com/scholar?q=Amundsen+Ranes+studies+on+traffic+accidents+in+Norwegian+road+tunnels). The right reflexes: take off your sunglasses before entering, slow down, and leave a generous gap to the vehicle in front.

On the west coast there is no avoiding them: many national roads cross the fjords by ferry, and your GPS route includes these crossings like any other stretch of road. The main links run every 20 to 40 minutes during the day in summer, with no booking needed in most cases: you join the queue, drive on board, and payment increasingly happens automatically by number-plate recognition (the AutoPASS ferry system), billed to the rental company which then charges the card left as guarantee.

Two planning tips: first, build in slack — a longer-than-expected queue on a July Saturday can push your whole day back; second, check evening timetables, as some smaller crossings stop early or switch to reduced service off season. Crossings also count in the budget: from a few euros to several tens of euros depending on length, on top of urban tolls and toll tunnels — our article on tolls and AutoPASS explains exactly how it works with a rental car.

The triangular moose warning signs are not decorative: collisions with large wildlife are a real risk, especially at dawn and dusk, and even more so along forest edges in the east and centre of the country. In the north, reindeer occupy the road instead, sometimes in whole herds. The rule: slow down as soon as a sign marks a crossing zone, scan the verges, and never swerve violently to avoid an animal — hard braking in a straight line is always the better option.

Norway is very much drivable in winter — Norwegians drive all year round — but not in just any conditions: winter tyres are standard (rental companies fit all their vehicles in season, often with studded tyres in the north), mountain roads close or switch to convoy driving behind a snowplough, and days are very short above the Arctic Circle. If you are chasing the northern lights in a rental car, stay on cleared main roads and check pass closures before each leg — our article on when to visit Norway details what each season changes on the road.

Norwegian driving presents no technical difficulty in summer: roads in excellent condition, clear signage, calm drivers. The real adjustment is mental: between 80 km/h limits, winding fjord roads and ferries to slot in, you rarely average more than 50 to 60 km/h in real terms. A route that looks short on the map — Bergen to Geiranger, for instance — fills an entire day. Plan legs of 200 to 300 km at most, and Norway becomes one of the most beautiful countries in the world to drive.
