These short study cards teach concepts and inspection points. They are separate from the exam-style question bank and do not change your practice scores or Journey progress.
Use the official manual for your testing state and the complete inspection procedures for your vehicle. Pressure benchmarks and equipment details can vary; a flashcard is a recall aid, not a complete operating procedure.
