@bookman My post #58 comment wasn't aimed at you, but our "friend" Hamlet07 who comes across as sarcastic

Helmet, Engine size (125cc or 50cc in many cases), Toxicoligy (Drink/Drugs) or Licence are among the most common "get out" clauses used by insurers. Anyone unable to tick all 4 can expect similar probs.

Well those four are definately Fair to be observed but when they try to pull a swifty under your nose and refuse to honour their obligations it's another thing.....

Ticking all 4 substantially reduces the chance of insurers wriggling on a technicallity. 3 on a bike or driving the wrong way up a one way street etc is a different matter.

The "Treaty" to which the last bullet point of Section 42, and Section 42-2 refers is the Vienna Convention 1968, which supercedes the 1949 convention. It is the Convention, not the Thai Government, that stipulates that an IDP is not valid unless a corresponding drivers licence of the home country can be produced.

That is the other way around from what I am saying. You're stating here an IDP is not valid unless a home license is produced, I am saying the IDP is not necessary.
