International Driver's Licence is Mandatory
Riding a motorbike in Vietnam requires proper documentation, as foreign licenses alone do not satisfy local legal requirements. One must obtain an International Driving Permit that Vietnam recognises, or alternatively convert one's home country license to a Vietnamese license, though this process presents considerable complexity for most travellers. Enforcement of these regulations varies, Nha Trang seems to be seasonal. Da Nang happens all the time.
