Secondary controls are designed primarily to do what?

• A. Provide backup functionality to primary controls.
• B. Shut down the engine in an emergency.
• C. Assist you in safely operating your vehicle.
• D. All of the above.

Answer: (C)

Secondary controls exist to help you manage tasks that support safe driving without taking over the actual motion of the vehicle. They cover things like signaling your intentions, keeping you visible and knowing what’s happening outside the cab (lights, wipers, horn, mirrors), and handling safety-related functions that you need while you focus on steering and speed. They aren’t intended as backups for the primary controls, nor are they meant to shut the engine off in an emergency—that would be handled by separate emergency systems. So their main purpose is to assist you in safely operating the vehicle.
