Eager to drive combination vehicles? Well, to qualify to do that you need to earn your combination vehicle endorsement and the best way to ensure you are ready to do that is to take our free New Jersey CDL Combination Vehicles Practice Test. Featuring questions like these: How do you make sure air lines are not crossed and a trailer’s brakes are working and what should you always do before backing under a trailer? In all there are 20 multiple choice questions on the test and you need to answer at least 80% of the questions correctly to pass. Passing the practice indicates you are ready to take the combination vehicles endorsement exam, which is required for drivers who want to drive tractor trailers, double- and triple-wide and straight trucks with trailers. These types of trucks require extensive knowledge and the endorsement test helps verify drivers have that knowledge.

If you fail to pass our practice test, you can take it as many additional times as you like and each time you do the questions will be reordered to create a new test experience. While taking the practice test you will also be able to benefit from such bonus features as answer explanations, a progress tracker and instant results. Why risk having to go back to the DMV and retake your endorsement test? This will take time and cost money for additional test fees. Instead, take our practice test and ensure you are ready to pass on your first visit.
