As regular foreigner/travelers who are traveling through Vietnam, you will generally not be able to purchase the 3rd party Insurance for your Motorbike Tours locally that you can actually use. Local sellers or other rental agencies might offer to sell you a 3rd party yellow insurance paper. For you, this does nothing. To have the yellow insurance is merely a guideline in Vietnam and you should not rely on it for anything.
Before departing on your vacation, you will want to check with your local insurance agency about providing insurance for motorcycle rental within Vietnam. They will give you precise information on what they offer and how it might cover you in the event of a significant accident in Vietnam.
