I hold an EU driver's license (no expiry date), and used it to obtain a HK driver's license, which I then used to obtain a HK international driver's license. But now I only have the physical EU license and the HK international driver's license. I've misplaced that flimsy actual HK license.
When renting or driving a family a car abroad (in the EU, but not the same country as my license), do I need to show my actual HK license that I used to obtain the international license? Or just use the EU license and not bother with the HK International one? (I haven't lived in the EU country for a long time, but have kept this driver's license...)
