CDL Test Prep for Android

Pass your Commercial Driver's License (CDL) exam with our comprehensive practice tests and flashcards.

Other companies may try to provide you with the highest number of questions, but we aim to provide you with the highest quality questions. Our practice questions have been thoroughly researched to ensure the quality matches that of the real exam.

The app has 3 modes: test mode, study mode, and flashcard mode. In test mode, the test will be timed and graded. You will be able to see what areas you are weak on and explanations for the test questions. In study mode, the exam will not be timed and you will see the answer and explanation right after answering a question. In flashcard mode, you will be able to go through flashcards as well as grade yourself.

The free version of the app contains a subset of practice questions and flashcards. The premium version gives you access to all questions and flashcards.
