Nowadays, it is absolutely normal to travel to other countries by car. Nevertheless, it is useful to find out before travelling abroad what documents are required when crossing the border.
Some countries still request a Green Card to confirm that there is comprehensive insurance cover abroad.
Vehicles entering Switzerland or the Principality of Liechtenstein without sufficient motor third party liability coverage must conclude a frontier insurance.
As a precaution, it is also advisable to bring along a European Accident Report, which is available in many languages.
