USA on a Norwegian Licence 2026: 50 Rulebooks, 0.08 Alcohol
Norway
United States
Licence rules are set state by state. Both countries signed the 1949 convention, so carry a 1949 IDP with your Norwegian licence. Same side of the road; the US limit is 0.08% vs 0.02% at home.
Norwegians tend to settle into American driving quickly: traffic keeps to the right, cars are mostly automatic, and the distances feel familiar. What changes is the rulebook, because in the United States most road law is written by each state, not by Washington.
Licence and permit
There is no single national rule on foreign licences; each state decides how long a visitor may drive on one. What links the two countries is the 1949 Geneva Convention on Road Traffic: Norway joined in 1957 and the United States in 1950. That treaty is what obliges American authorities to recognise a 1949 international driving permit, which gives an officer or a rental agent your details in a standard format alongside the Norwegian card. Get it before you leave Norway, and carry it with the licence and your passport. If your trip crosses several states, the Driving Permit Checker is a quick cross-check.
The alcohol gap
The WHO country profiles put the US limit at 0.08% blood alcohol and Norway’s at 0.02%, four times stricter. Do not read the American figure as permission: drink-driving arrests carry jail risk, licence loss and high costs for a visitor. Keep to zero before driving.
Speeds and signs
Limits are posted in miles per hour and vary by state and by road; an interstate in one state can be faster than in the next. Speeding tickets are set locally, so amounts differ widely; the Speeding Fine Calculator gives a rough idea.
Emergencies
Call 911 for police, fire and ambulance anywhere in the country. The United States driving guide covers state differences in more detail.

Frequently Asked Questions
For a visit, yes, but each state sets its own rules for foreign licences. Norway and the United States are both parties to the 1949 Geneva Convention, so the 1949 international driving permit is the document American police and rental desks are bound to recognise. Carry it with your licence and passport.
Yes. The national US figure is 0.08% blood alcohol, four times Norway's 0.02%. American drink-driving penalties are heavy, so keep to your Norwegian habit of no alcohol before driving.
Yes, both drive on the right. The adjustments are speed limits posted in miles per hour and rules that change at each state line.
