What should i do if the police in Vietnam stop me to check paper-work meanwhile i have no proper driving license ?
For the police, presenting legal documentation will aid in keeping you out of trouble. From the perspective of your insurance company, you will not be covered if you are doing something illegal. Like driving a motorcycle in Vietnam without a proper permit. If you were to get into an accident that requires an insurance payout, you would want to have all your documents in order.
However, that is a fact that rarely the police stop foreigners to check the paper-work if you are riding vehicles safely because almost Vietnamese police hardly speak any foreign language and this is also a quite sensitive matter relating to the politics. However, if the police stop you to check paper-work, our tour guide getting along will help you deal with them directly & friendly then everything will be fine.
