The Norwegian authorities regularly monitor compliance with speed limits, parking rules, and tolls on the roads. Speeding in Norway can be punished by imprisonment!
When driving into Oslo and some larger cities, you must pay a toll. The authorities automatically register the entry (based on the license plate number). Foreign-registered vehicles are no exception, of course.
Drivers should know that the Norwegian traffic rules ensure increased protection for cyclists and pedestrians, and the latter move around, assuming that cars respect this legal preference indeed.
As a general rule, winter tires are mandatory for all vehicle wheels from November 15 to March 31.
“On Norwegian roads, you can drive at a maximum of 80 km/h, motorways are minimal even around the capital, there are plenty of 60-70km/h signs and automatic traffic lights, no-overtaking sections are taken very seriously, and there is often a fence between the two lanes. So don’t expect to tear along Norwegian roads. And if you have to factor in ferry-crossings and steep climbs, then your average speed will probably not get above 50km/h.
Inhabited settlements are rare, but at least gas stations are frequent enough. These, however, are often fully automatic (you pay with a credit card).
There is an automatic toll collection system on the roads (Autopass) the cost of which you pay after your trip. Signs indicate how much you have been charged for a given section. They also collect it from a rented car (Though how do they charge foreign cars?)
There are also many ferries, which are frequent, large, and considered part of the road network. These can also transport trucks and motorhomes.
The only thing more numerous than the ferries is the tunnels. These can be very long, including one famous example which runs for 25km.
The traffic is mild, and everyone is terribly patient and polite
Gasoline costs 15-16 NOK /l (diesel is cheaper).
So don’t expect anyone to move fast. (2015) "
“Transport in big cities is generally good, but it’s worth finding out in advance which company runs the most services in a given city (Stavanger - Colombo, Bergen - Skyss, Oslo - Ruter), and it can also be useful to download the application of the given company to your phone in advance, as the ticket is often cheaper through it than from the driver. It’s even useful to know that you can buy a sightseeing card in Bergen and Oslo, which provides free public transport, among other things (the Bergen card, for example, is valid for the whole county, which can also be practical).
Long-distance transport, however, is a tougher proposition. Several independent bus companies are competing with each other, so the system is complicated, and there are no timetables posted at bus stops outside the cities, making the situation even more interesting. Fortunately, the signal strength is excellent almost everywhere, so if you start with enough mobile data, it shouldn't be too much of a problem. You can find out about long-distance train tickets online (NSB), but what you should know is that prices can change over time, i.e. the system does not show fixed price, though I generally had good luck in this regard. Either way, bus and train connections between cities are not very regular, so if you miss your departure, you might have to wait many hours, or even a whole day, until the next bus or train leaves
A car can be an obvious solution, but in many places, you have to take a ferry, or possibly cross a toll bridge, not to mention the horrendously expensive parking. Still, this can be much more comfortable and convenient, and can prove particularly useful given the long distances.” (2019)
