Read full description

Pass the Taiwan written driving test the first time, for a car or a scooter. This app contains the complete official question bank published by Taiwan's Directorate General of Highways, all 2,172 questions, translated into 8 languages. Every question you will see on exam day is in here. WHAT IS INSIDE • 1,090 car questions and 804 motorcycle questions • 152 road sign questions with the original official graphics • 126 hazard perception video clips, the same official set used in the real test • Mock exams with the real format and timer, 40 questions for car and 50 for scooter, pass mark 85 STUDY IN YOUR OWN LANGUAGE English, Chinese, Vietnamese, Indonesian, Thai, Japanese, Burmese and Khmer. Switch language whenever you want without losing your progress. THE WHOLE LICENSE PROCESS, STEP BY STEP The written exam is only one part of it. The Guide tab walks you through everything else, whether your foreign license can be exchanged without taking any exam at all, the medical certificate, the fees, how to book your test slot online, what happens on exam day and what to bring with you. For scooter riders there is one step almost nobody knows about. You cannot even book the exam until the hazard perception result is on your record, and the 126 clips in this app are that same official set. BUILT FOR STUDYING • Review only the questions you got wrong • Bookmark the tricky ones • Full mock exam history, and retake any of them • Questions read aloud • Dark mode and adjustable text size • Works offline, no connection needed to study • No account, no sign-up, nothing to fill in FREE, WITH ONE OPTIONAL PURCHASE Everything above is free, paid for by ads. If you would rather study without them, a single one-time purchase removes them for good. No subscription. This app is not affiliated with, endorsed by or operated by any government agency. The question bank is public material published by the Directorate General of Highways, MOTC.
