Are you planning to travel abroad in your car? Why not get a car rental? There two advantages for doing that: 1) you pay a price that you’re accustomed to, in your national currency and 2) you sign a contract that is written in a language that you understand, this being way more comfortable than trying to make out its meaning or counting solely on what the rent a car agent will try to communicate you.
You will usually need an authorization from the rent a car company. Mind that it should be authenticated and signed by a notary. The other two things you be needing are the Green Card and an CASCO (additional insurance) extension.
Some rent a car companies charge a small amount of money (about 50 euros) to cover the Green Card and CASCO extension costs. Regarding the latter, the Green Card, the countries included in the standard insurance are: Austria, Andorra, Belgium, Bulgaria, Switzerland, Cyprus, Czech Republic, Germany, Denmark, Spain, Estonia, France, Finland, UK, Greece, Hungary, Croatia, Italy, Ireland, Luxembourg, Lithuania, Latvia, Malta, Norway, Holland, Portugal, Poland, Romania, Sweden, Slovakia, and Slovenia. The countries that are not covered by the standard insurance are: Albania, Bosnia and Herzegovina, Belorussia, Israel, Iran, Morocco, Moldavia, Macedonia, Russia, Serbia and Montenegro, Tunis, Turkey, and Ukraine.
The CASCO, which is an additional car insurance, extension consists of coverage of all the risks, including partial or total theft, just like for damage done in Romania. Other things that you should inquire about are the medical kit, the warning triangle, and the extinguisher. There is no reason why you shouldn’t get a ticket if your carrying an expired medical kit or anything else for that matter. Your rent a car agent will probably take care of those.
These being said, don’t leave behind your ID card or passport, if your traveling outside the EU, and have a nice ride!
