Quick question - if I hire a car in Europe, what are the rules about driving across a border into another country? Am I allowed to do that, do I have to declare to the car rental company at the time so that my insurance is valid etc.? Off to work in Poland shortly, planning to hire a car to drive to Brno for the GP and was wondering about the legalities of it
Depends where you are, where you are going and what you're driving.
I worked in Dresden for 8 months a few years ago and wanted to drive to Prague for a long weekend. Had a mercedes A Class at the time and the rental company would not let me take it to Prague. However they were more than happy for me to take an Astra... Lovely.
Like i said, was about 5 years ago so the rules could have changed seen as we are now one biig happy european family!
