What is a IDP ? it JUST a translation of your Chinese driving license and is not a legal document and must be used alongside your DL.
So for the life of me I can't see how having a IDP makes you more legal ? or not having one makes you illegal.?
The fact of the matter is you are fully legal with your C1E to ride a motorbike and all you have to prove in a country that don't understand Chinese DL that you are covered to ride a bike hence the IDP.
