The following is in the category of "must read" as Norway has some very strict driving regulations and on the spot fines may be levied if you contravene them.

Driving:
Norwegians drive on the right, overtake on the left.
At junctions, unless you are on a priority route (marked with a yellow diamond), you should always give way to traffic from the right.

You should always use dipped headlights 24 hours a day.

In winter, snow tyres must be used. These are normally studded and whilst they do make driving somewhat noisy, they really do make a difference.

Norway has very strict drink driving laws, only allowing 0.1milligrams of alcohol per litre of blood - stricter than the UK where the limit is 0.4, and the strictest in Europe.

You are required to carry a warning triangle and it is recommended that you should also have a first aid kit and spare bulb kit.

Seat belts front and rear are obligatory everywhere. Children under 4 years old must use a proper seat or restraint. Over 4, children should travel in the rear and be properly secured.

Driving licences should be carried at all times.

Speed Limits
As a rough guide, the following speed limits apply, though there are often restrictions on these. Be warned - the Norwegians like their radar traps!

The speed limit on Norwegian motorways is either 90 km/hr or 100 km/hr . Mobile homes or cars towing camping trailers may not exceed 80 km/hr on these sections of road, which are well signposted.

In general the speed limit on Norwegian roads is 80 km/hr, with a 60 km/hr limit for camping trailers without brakes and with a weight exceeding 300 kgs. In built-up areas the speed limit is 50 km/hr, while in residential areas it is sometimes as low as 30 km/hr. Watch out for speed bumps, they are always signposted.

Motorcycles: Helmets are compulsary and, like cars, headlights must be used 24 hours a day.
