Just like the traffic on Vietnam's roads, the country has racked up a solid reputation for changing direction without warning on driving laws for foreign visitors.
Staying consistent with that it has just been announced that from the beginning of December 2017 international drivers licenses issued in the UK and Australia (we are still waiting to hear of any other countries that have been added to the list) will no longer be recognised countrywide.
This means that those without the appropriate license to drive legally in their own country will need to apply (and take the test) for a Vietnamese drivers license before jumping on a rental scooter to be covered by their travel insurance.

For those with a license to drive, you'll find more details on how to convert your license and helpful links at the bottom of this post.
Plus some sound advice from Travel Fish about the legalities and insurance providers that will cover you if you have the correct licence for riding a bike back home
If you already hold a valid drivers license in your home country (and have held it for at least six-months) you can easily convert it to a temporary Vietnam license by filling out the downloadable form here and submitting the form in person in either Ha Noi or Ho Chi Minh government transportation offices.
If you don't have a license in your home country forget taking a test here in Vietnam. There are very few tests held in English (the theory test alone is made up of 150 questions - try that in Vietnamese) and even if you do pass, the license can take up to three months to issue.
