我有外國駕駛執照, 如果回港申請香港駕駛執照, 可否直接排期考試 !!??

如果你持有外國駕駛執照,
可以唔使再考香港駕駛執照,
可以向運輸署申請免試換領香港駕駛執照.
詳細情形, 可以上以下網址.

First of all, have you got the foreign licence already? If you do, you can just simply go to Transportation Department to convert your foreign into HK's licence. You don't need to take any driving course neither writing test. On the other hand, if you didn't get licence from foreign, then you have to take writing and take a driving course from 駕駛學院!!!
Hope this can help you!
