 What the Course Entails and Exam Details

The Combination Vehicles endorsement course covers a wide array of critical topics designed to ensure road safety. To pass the official exam, you must demonstrate a thorough understanding of the following areas:

• Combination Vehicle Safety Systems: You will learn the function and operation of essential systems, including air brake systems, anti-lock braking systems (ABS), and coupling devices. This section covers how these systems work together to control the vehicle.
• Coupling and Uncoupling: A major portion of the course is dedicated to the step-by-step procedures for safely coupling (connecting) and uncoupling (disconnecting) a tractor and trailer. This includes inspecting connections, ensuring the fifth wheel is properly locked, and performing a tug test.
• Pre-Trip Inspection: You must be able to perform a comprehensive pre-trip inspection specific to combination vehicles. This involves checking the coupling system, air lines, electrical connections, and all standard vehicle components.
• Safe Driving Practices: The course addresses the unique handling characteristics of combination vehicles, including off-tracking (how the rear wheels follow a different path than the front wheels), rollover risks, and special braking techniques to avoid jackknifing.
• Air Brake Testing: You will need to master the detailed steps for testing the air brake system, including the static pressure check, applied leakage test, low air pressure warning signal test, and the emergency pop-out valve test.
