You can't help but notice them as you approach Oslo. Between the border on the E18 and the Norwegian capital, seven pay stations pass - and then they come increasingly tight.

In Oslo itself there are now as many as 83 customs passages. And anyone who does not have a special agreement with the customs company must pay for each passage.

The new customs stations opened in June - just before the holidays. And they have raised protests.

- It's crap. It will be very expensive and there are those who have to use the car, says Oslobon Per Gunnar Gunnersen.

Customs rings around the cities

Financing roads with tariffs is nothing new in Norway, but in recent years tariffs have become more and more. And they are used to a greater extent to control - and limit traffic.

Around the big cities such as Oslo, Bergen, Stavanger and Trondheim there are so-called bombings that will reduce traffic.

The Green Party, which governs the municipality of Oslo together with the Social Democrats and the Norwegian Left Party, has driven the development.

- If you drive in Oslo, you should pay for the place you take up on the roads and for the pollution you emit. We believe that it is right for those who pollute and take up space pay for themselves, says Sirin Stav, who is running for office in Oslo for the Environment Party in the Norwegian municipal elections in three weeks.

Complicated system

But what does it cost to drive a car in Norway? Yes the system is not completely easy to understand for the uninitiated.

There are five different publicly owned customs companies, with different tariffs and different rules for when and how much to pay.

It is clear, however, that the Norwegians paid significantly more than we Swedes. In Norway, the sum of the customs duties paid was SEK 11 billion last year, while congestion fees in Stockholm and Gothenburg withdrew just over two and a half billion.

Driving into Oslo can cost around SEK 60-70 easy way, but then you have to pay again each time you pass one of the 83 customs stations. If you do not have a special agreement with the customs company - then you only pay once an hour. The bill may come as late as three months afterwards.

Shared city

And the system shares the Oslo people.

- I am because there will be smaller cars in the center, says toddler mother Lil Katrine Bödal after some hesitation.

- I don't know if I dare say it on TV? That's so, so many who are against!

Per Gunnar Gunnersen, on the other hand, is steadfast in his - quite the opposite - position.

- It's far too many customs. Look around, you do nothing but drive through customs all day.
