Pass the Taiwan written driving test the first time, for a car or a scooter. People do not fail on the questions. They fail on the process, which licence they can even apply for, where to book, what to bring, what the fee is, what happens on exam day. Other apps have the questions. This one has the questions and the process. NOT A GOVERNMENT APP This app is independent. It is not affiliated with, endorsed by or operated by Taiwan's Directorate General of Highways, the Ministry of Transportation and Communications or any other government agency, and it does not provide any government service. You cannot book, pay for or take an exam through it. It is a study aid built from information the government publishes for free, and every government page it uses is listed under SOURCES at the end of this description and in the Official resources section of the app's Guide tab. THE LICENCE PROCESS, STEP BY STEP The Guide tab is the part no other app has. Whether your foreign licence can simply be exchanged, the learner permit, age and medical requirements, every fee, how to book your slot online and when booking closes, the scooter safety lecture you have to sit before you can even register, what to bring on exam day, and what the practical test scores you on. WHAT IS INSIDE • 1,090 car questions and 804 motorcycle questions from the official question banks • 152 road sign questions with the original official graphics • 136 hazard perception video clips from the official sets, 126 for scooter and 10 for car • Mock exams in the real format, 50 questions for car and for scooter, pass mark 85 STUDY IN YOUR OWN LANGUAGE The car and motorcycle banks are available in English, 中文, Tiếng Việt, Bahasa Indonesia, ไทย, 日本語, Burmese and Khmer, using the government's own translated editions.
