Vietnamese driving license are mandatory for all drivers of motor vehicles as well as for riders of motorcycles with a capacity of over 50cc. Non Vietnamese citizens are only permitted to drive in Vietnam if they hold a temporary Vietnamese driver's licence. To convert a UK driving licence or an International Driving Permit into a temporary Vietnamese driver's licence, the applicant must first hold a valid Vietnamese residence permitof at least three month's validity and a current UK driving licence or a valid International Driving Permit.
