My experience at Phuket DLT is not similar. And I only got two years.
No need to use the DLT Smart Queue App.
Bring the papers, queue to get the papers checked, then I got an appointment for later that day.
Went back, got the papers checked again and got an appointment for one month later.
Went again one month later (this Monday), queued to get the papers checked again.
Anther queue for another form, a queue for paying, and then a queue for the test.
After the test and yet a queue I got my license.
At the first desk they marked my papers with 2 years license. I tried at every desk to point out that the DTV is a five year visa, but to no avail; I only got two years.
