STUDY IN ENGLISH, UNDERSTAND IN YOUR LANGUAGE
Questions stay in English. When a word or sentence stops you, tap Translate to read the question, its answers and the explanation in Spanish, Portuguese, Russian, Ukrainian, Polish, Turkish, Vietnamese, Chinese, Arabic, French, German or Italian. Questions you answer with translation on come back for review, so you can be sure you know them in English. Translation needs an internet connection. The app's interface is also available in Spanish.
CDL PRO
Without a subscription you get 9 practice tests (269 questions), unlimited timed exams drawn from all 907 questions, mistake review, every state handbook and a limited number of translations. CDL Pro, an optional auto-renewing subscription, unlocks all 32 practice tests and raises the translation limit.
Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is canceled at least 24 hours before the end of the current period, and renewal is charged within 24 hours before the period ends. Manage or cancel anytime in your App Store account settings.
