When to apply: Apply at least 3 working days before the planned date of arrival.
Uzbekistan and Vietnam are both party to the 1968 Vienna Convention, so an International Driving Permit issued in Vietnam is one Uzbekistan is bound to recognize.
Whether a permit is required alongside your national license is set by national road law, which we have not checked for this pair.
Passport validity — The UK government says that to enter Uzbekistan your passport must have an expiry date at least 3 months after the date you arrive.

How long can Vietnamese citizens stay in Uzbekistan?
Up to 30 days per entry.
How far in advance should Vietnamese citizens apply?
