I've been investigating the possibility of operating cars registered in Europe in the USA and registered in the USA in Europe.
Car registered in the US can be driven on EU roads for a year. When entering EU, the operator has to have insurance for damages he or she may cause on EU roads. It's the law. I think such insurance cost about €1600/year for regular car.
After a year, the car has to leave or be registered in EU.
I found out that non-USA-residents can bring their cars(registered outside of the US) with them. The car has to leave with the person or after a year.
However, I did not find anything about insurance.
Does somebody from you know how it's with insurance?
