One of the fastest ways to assess your readiness to pass the New Jersey CDL exam is to take our NJ CDL General Knowledge Practice Test Simulator. This test is the second one in our General Knowledge series, and it contains 50 multiple choice questions that will thoroughly test your driving knowledge. There are questions on topics ranging from basic vehicle operation to vehicle inspections to winter driving to handling emergencies and much, much more.

Here are two examples of the types of questions that you will find on this practice test: If you are driving a 30-foot vehicle at 55 mph, how many seconds of following distance should you allow? How do you use in-vehicle communications equipment cautiously? To earn a passing score you will need to answer at least 80% of the questions correctly to pass. However, you can take the test an unlimited number of times until you earn a passing score.

So are you ready to identify your strengths and weaknesses and ensure you are prepared for the NJ CDL exam? If so, take this practice test now. You’ll be one step closer to becoming a licensed commercial driver in the Garden State.
