About this practice test
A full-length mock exam that mirrors the real test:
- 25 multiple-choice questions
- Pass: 20 correct (80%) — NY DMV's published passing score for every CDL knowledge test
- NY DMV does not publish the question count or a time limit; 25 questions is the standard AAMVA Air Brakes format, and 30 minutes is used here for practice
Take it under real conditions — answers and explanations are shown at the end.
