My insaurance man has returned with news.
Not a single Swiss insurance company proposes any kind of cover for car or motorbike in Russia.
He knows of French insurance companies that cover Russia and this is specifically written on the Green International Insurance Card.
So I'll need to buy an insurance at the border, Russian side supposedly.
He also points out that I need to enquire whether this policy is only RC/Public liability (Responsabilité civile) or Casco (vehicule dammage) or theft. He strongly suggests to take out all possible coverages, because on one hand they shouldn't be too expensive and for a one off occasion worthwhile taking!
I'll try to arrive mid-day in Ludza, settle in the "hotel"and have a go at the border in the afternoon to see how things look.
Perhaps I allready could buy an insurance policy for the next three days!
