Ukrainian car insurance: Green card insurance taken out with a Ukrainian insurance company on the Hotline Finance website (damage caused to third parties : only damage caused to others is insured) is valid in France and the European Union.
French insurance can be arranged if you have registered your vehicle in France properly. However, the price is high, because with Ukrainian license you will not have a bonus discount.

Some insurances add free of charge to the home policies of the Ukrainian displaced persons you host. They benefit from a civil liability insurance and a school insurance.
