About this practice test
A full-length mock exam that mirrors the real test:
- 20 multiple-choice questions
- Pass: 16 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; 20 questions is the standard AAMVA Combination Vehicles format, and 25 minutes is used here for practice
Take it under real conditions — answers and explanations are shown at the end.
