CA CDL Air Brakes Practice Test 2 2025

While you may not be a pilot landing a plane at LAX, it is just as critical for you to learn about operating air brakes. Air brake systems are standard equipment on most semi-trucks, tractor-trailers, and buses. Restrictions on your California Commercial Driver’s License (CDL) that prevent you from operating air brakes will severely restrict your ability to qualify for highly sought-after jobs in multiple sectors, including technology, entertainment, and manufacturing. Your understanding of how to apply air brakes will keep you safe while driving through difficult-to-navigate turns and in heavily congested traffic areas. While safety comes first, it must be exercised by receiving the appropriate training.
