Travel insurance
It's a good idea to have travel insurance.  Regardless of the existing bilateral health care agreements, only a few EEC member countries entirely cover health care costs.  An illness or accident abroad can bring about unexpected costly trip, hotel and travel expenses, a good reason to be insured.

Vaccinations
No vaccinations are currently required when visiting any of the 25 EEC member countries however some immunizations are required or recommended for a few overseas countries. Always ask your physician before departing for these destinations.

Documents required

Passport or Identification Card
There are no longer immigration controls on the EEC countries' borders, however it is necessary to have your passport with you when traveling outside of these borders.  For public safety or national security reasons, occasionally and for limited time spans, border controls can be made.  Children must have their own passport or identification card or be recorded on their parent's passport.  If you are a citizen from the EEC, Iceland, Liechtenstein or Norway and are travelling within the EEC, no visa is required.  Citizens of many other countries outside of the EEC including Australia, Canada, Japan, New Zealand, United States of America and all EEC candidates except Turkey do not require visas for stays of 3 months or less.  For any questions, contact any EEC country's consulate nearest you.

Insurance documents
Don't forget to bring your travel documents, health care card and car insurance documentation.

Driver's licence
A EEC driver's licence is valid in all EEC countries.  The minimum driving age is 18 years old.  Persons younger than 18 are not authorised to drive in Italy even if they possess a legal driver's licence from another country.
The European Commission's website provides more detailed information regarding driver's licences.  In addition to your driver's licence you must have your car's registration card with you.

Car insurance
Your car's insurance policy will automatically provide, at no extra cost, the minimum coverage required by law (civil liability insurance).  If you are completely covered in your own country, make sure to check that you are also covered in foreign countries.  You might also consider the idea of getting extra insurance for on the road car assistance.
Although a green card is not necessary to travel in the EEC, this document is internationally recognized proof of an insurance policy and, in the case of an accident, making damage claims is much easier.  If you decide not to bring your green card with you, bring a copy of your insurance policy.  The green card system currently covers 43 countries and is managed by an insurance association.  It's website (www.cobx.org/public/EPAhome.htm) provides further detailed information on the system and its goals.
You can pick up a copy of a European accident report form, printed in many languages, at your local insurance company.  This form simplifies reporting an accident on location should you have one in another country.
New legislation has been introduced guaranteeing drivers faster damage reimbursement, regardless of where they are in the EEC.  The legislation provides for access to more detailed information, simpler procedures and faster claims payments as well as penalties in case of late compensation.  This legislation not only applies to accidents occurring in EEC countries but also to accidents occurring between 2 EEC insured members who have an accident in a third country belonging to the green card system.

Use of seat belts is required both in front and back seats in all EEC countries.
Use of mobile phones while driving increases the chance of fatal accidents five times.  It is directly or indirectly prohibited in all EEC countries.  Some countries tolerate hands free devices.
