VA CDL Air Brakes “Endorsement” Practice Test 2 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

If you’re interested in transporting people around Richmond or cargo for a commercial trucking company, such as Abilene Motor Express, an extensive knowledge of air brakes is essential. Your Virginia commercial driver’s license (CDL) must not contain an “L” restriction for you to operate most semi-trucks and full-size buses. The presence of an “L” restriction is a significant barrier to qualifying for some of the best driving opportunities. Air brakes provide the braking force necessary for you to slow down or come to a complete stop while transporting heavy loads. Adverse weather, sharp turns, and stalled traffic require you to make quick adjustments to your speed that air brakes make possible. Your ability to understand air brake system operations will keep you safe and make you more competitive in the job market, but you must obtain sufficient training to exhibit the required skills.

Our Virginia DMV CDL air brake “endorsement” practice test is an excellent resource to help you remove the “L” restriction from your CDL. To become air brake-certified, you must pass a skills test (including conducting an inspection of the air brake system) and an official Air Brakes Knowledge Test. You are required to correctly answer at least 80% of the 25 questions on the official knowledge test to receive a passing score and avoid a one-day waiting period to retest.

Designed to deliver outstanding results, our Virginia DMV CDL air brake “endorsement” practice test mimics the format of the official knowledge test. The practice test quizzes you with 30 questions, similar to those on the official knowledge test, to establish a baseline of your air brake comprehension. It also highlights the information you must learn to improve. You can depend on the practice test to rapidly expand your knowledge base.

This Virginia DMV CDL air brake “endorsement” practice test elevates your knowledge of air brake operations with authoritative information. The practice test is based on the most recent Virginia DMV CDL manual (Virginia CDL Handbook 2025) and is up to date as of October 2025. Any wrong answer you submit will generate a thorough explanation of the correct one using information taken directly from the CDL manual.

Using a much different approach, traditional study methods are not designed to address your specific misconceptions about air brake operations. Instead, traditional study methods are focused on helping you memorize the answers to the questions without providing additional instruction to eliminate your misunderstandings. The practice test outperforms traditional study methods by elevating your skills with reliable information, boosting your confidence to apply its teachings, and increasing your chances of passing the official knowledge test on your first try.
