10 expensive mistakes on a Norway road trip, and how to avoid them

The short answer (status: October 2026): the costliest mistakes on a Norway road trip are made at home, before you leave. They include a vehicle measured without its bike rack, no toll registration, a heavy motorhome without a tag, and a route built around a mountain road that hasn't opened yet. None of this is meant to put you off. A good plan saves money and saves the holiday. Every figure below comes from the official source listed at the end of the article.

The ten at a glance

1. Not measuring the vehicle with the bike rack on

Ferry fares are based on length, including everything mounted on the vehicle. The 6-metre line is the expensive one. On the shortest crossings in 2026, a vehicle under 6 m pays NOK 51 at full price and one of 6.01–8 m pays NOK 117. On Bodø–Moskenes to Lofoten, the same step goes from NOK 605 to NOK 1,302.

Avoid it: measure the vehicle as you will drive it, with the rack, bikes and roof box on, and register that length. → Norway tolls and ferries explained

2. Not registering for tolls

Norway has no toll booths. Cameras read your plate, and a foreign vehicle is invoiced afterwards. If you have not registered, the cost of looking up your address is added: EUR 5.10 for a German plate, according to AutoPASS (as of 1 May 2025). If your emission class or fuel type is not registered, you are also charged the highest rate. A tag with an agreement gives 20 % off.

Avoid it: register with Epass24 before you go, or order a tag weeks in advance. Vehicles up to 3,500 kg cannot get one at the border. → How do you pay Norway's tolls?

3. A motorhome over 3.5 t without a tag

A motorhome in category M1 over 3,500 kg is charged as a light vehicle only with a tag and a valid agreement. Without them, it is billed as heavy. At Hardangerbrua that means NOK 428 instead of NOK 143, and in the Ryfylke tunnel NOK 357 instead of NOK 119. For company-registered vehicles over 3.5 t, which includes most heavy rental motorhomes, a tag is mandatory and the fine is NOK 8,000.

Avoid it: order the tag, give the provider the vehicle category (M1) and the maximum authorised mass, and get the rate group confirmed in writing. → Norway tolls and ferries explained

4. Paying for ferries without an agreement

A prepayment agreement gives private customers 50 % off ferries in the AutoPASS scheme. A tag alone gives 10 %. Paying the crew on board gives no discount. Without any agreement, the invoice comes by post with a fee, which official pages give as NOK 35 or NOK 10. The prepayment for vehicles up to 8 m is NOK 2,200, and the unused balance is refunded when you cancel.

On some routes, summer costs more as well. In 2026, Møre og Romsdal and Nordland applied higher summer fares from 1 May to 31 August.

Avoid it: if you will take several ferries, open the prepayment agreement before you leave. → Norway tolls and ferries explained

5. Building the route around a closed pass

Trollstigen has opened as early as 29 April and as late as 12 June in previous years. Gamle Strynefjellsvegen has opened on 15 May in one year and 29 June in another. After opening, these roads may still close at night and in bad weather. In autumn 2026, Trollstigen was also closed on weekdays for rockfall work.

Avoid it: before late June, plan a fallback for every pass, and check the status the evening before. → Western fjords: 10-day road trip

6. Not checking tunnel closures

The Lærdal Tunnel on the E16, between Bergen and eastern Norway, closes from 16 November 2026 for upgrade works. It will be shut every night from 18:00 to 06:00 for about two years, but open on the night to Sunday.

Avoid it: in autumn and winter, check the road authority's traffic information before any day on the E16.

7. Sleeping where it is banned

Lofoten's outdoor regulation bans motorhomes between 24:00 and 06:00 at twelve named car parks. At Preikestolen, sleeping in vehicles is strictly forbidden. At Trolltunga's P1 car park, overnight sleeping is not allowed. The road authority says ferry terminals and rest areas are not intended for overnight stays. In the worst case, a breach can lead to a police report and a fine.

Avoid it: decide on the night's spot by mid-afternoon, and read every sign. → Can you park a campervan overnight in Norway? and Where to sleep with a camper

8. Holding your phone while driving

The road authority says using a mobile phone without a hands-free system can cost a fine of NOK 10,000.

Avoid it: put the phone in a fixed holder and set the route before you drive off. More rules that surprise visitors are in our article Driving in Norway.

9. Lighting a fire in summer

From 15 April to 15 September, lighting a fire or handling anything flammable in or near forest and other open country is prohibited, unless the municipality allows it. When the fire risk is especially high, a municipality can ban fire everywhere outdoors at any time of year.

Avoid it: cook on the vehicle's gas, not on a disposable barbecue in the heather.

10. Reading parking prices as final

Some municipalities publish their parking rates excluding VAT. In 2026, Moskenes in Lofoten lists NOK 36 per hour at Reine ytre havn, capped at NOK 499 per 24 hours, both before VAT. Norway's normal VAT rate is 25 %. By our arithmetic, that makes about NOK 45 per hour and about NOK 624 per day.

Avoid it: budget for parking with VAT included, and check the machine or the app. → Lofoten & Vesterålen: 7-day route

The point of all this

Every one of these mistakes can be fixed in an evening at home: measure the vehicle, register it, check the passes, plan the nights. Our guides go through each point in detail, and the boxes below show which guide covers what.

FAQ

What is the most expensive mistake?

For a heavy motorhome, it is having no toll tag, because it is then billed as a lorry at every toll point. For everyone else, it is usually the ferry length class.

Do I have to pay Norwegian tolls if I don't register?

Yes. The invoice still arrives, with an added lookup fee for finding your address.

When are the mountain roads open?

In past years, the big passes have opened between April and late June. Check the status for your own travel dates.
