For all countries you listed except Ukraine (ie. EU member states, see
European countries ) the minimum documentation UK citizens need on a UK registered vehicle is -
- full UK Driving Licence. Presumably both parts (still running on a green paper one myself)
- V5 registration Document
- letter of Authority from person/Company named on V5 if not travelling
- UK Insurance Certificate
- Passport
Insurance - UK Insurers include cover to all other EU states (+ Norway, Switzerland and little bits in between like Andorra, Monaco, Lichenstein, St Marino, etc) for up to a certain number of days a year, and you don't need tell them. But they only cover you for the absolute minimum legal requirement in each country, irrespectinve of the level of cover in UK. More costs more, but that is between you and them, not the authorities along the way.
Ukraine. Same as above except they do not accept the Certificate of Insurance. I asked my Brokers to cover me earlier this year for Russia and Ukraine and they said Norwich Union do not do it. I bought Russian insurance at the Estonia/Russia border (722EEKs = GBP33 for 2 months - motorcycle), and avoided Ukraine although I was told it could be bought at the Russia/Ukraine border when I was considering returning that way.
No Visas or Carnet required anywhere listed. Even Bail Bonds for Spain are virtually a thing of the past.
