Not to go off-topic, but the Germans (who are the only prosperous European country who do not toll) want to toll the autobahns but make the entire amount a tax credit, meaning Germans would in effect drive for free, assuming they have income. It is tied up in some kind of Euro "court".
I must respectfully disagree (in part) with the above.
Germany tolls its autobahn network, but
only for (what we in North America call) commercial vehicles.
Denmark has tolls on the E20 Great Belt Bridge crossing, and on the E20 Øresund Bridge-Tunnel to Sweden, and will have tolls on the new tunnel crossing between Puttgarten, Germany and Rødby. Otherwise, no tolls.
Finland has no road tolls at all, though it has been discussed from time to time.
Norway has quite a few toll roads and toll crossings.
Sweden has tolls on the E20 Øresund Bridge-Tunnel to Denmark and on the E6 bridge to Norway, and has congestion tax toll cordons around the downtown areas of Stockholm and Gothenburg.
The revenue collected in Stockholm is being used to build a western circumferential highway for "thru" auto and truck traffic, much of which will be in blasted-out tunnel. Not sure what the revenue collected in Gothenburg is used for.
Otherwise, all roads in Sweden are free of tolls.
