CT CDL Air Brakes “Endorsement” Practice Test 2 2025

An air brake qualification enables you to pursue some great commercial driving opportunities that offer enticing benefits. If you have an air brake restriction on your Connecticut Commercial Driver’s License (CDL), you will be excluded from driving most semi-trucks, tractor-trailers, and full-size buses in the Constitution State. Air brake systems are important for keeping you safe while transporting large amounts of weight. They provide sufficient force, enabling you to come to a complete stop. This ability is especially important for driving through low-visibility areas, heavily congested traffic, and hairpin turns. While it is important for you to learn how to operate air brakes, you should give careful consideration to choosing the source to teach you this skill.

Our Connecticut DMV CDL air brake “endorsement” practice test offers comprehensive instruction you can rely on for learning to competently operate air brakes. The process to remove the air brake restriction involves demonstrating that you can conduct a physical inspection of the air brake system, drive with air brakes, and pass an official Air Brakes knowledge test. The knowledge test requires you to correctly answer a minimum of 80% of the 25 questions to earn a passing score. The training that you receive from the practice test consists of 30 multiple-choice questions to assess your current knowledge level and identify the information you need to learn to improve it. You will benefit from the feedback you receive from the practice test by concentrating your studies on the topics you find most difficult to grasp.

This Connecticut DMV air brake “endorsement” practice test incorporates the most reliable and authoritative information into its teachings. If you get a question wrong, the practice test provides a thorough explanation of the correct answer. You won’t be learning surface knowledge that many traditional study methods, like study guides, teach you. Instead, the practice test handles your learning barriers and provides you with detailed information to overcome them. The practice test is based on the most recent Connecticut DMV CDL manual (Connecticut CDL Handbook 2025) and is up to date as of August 2025. You can be certain that you are receiving comprehensive instruction to address your specific learning obstacles.
