What is the primary purpose of a CMV's engine controls?

• A. Safely operate your vehicle.
• B. Start up and shut down the vehicle's engine.
• C. Warn you when pressures or temperatures reach a dangerous level.
• D. Help you steer, accelerate, brake, and park your CMV.

Answer: (B)

The main idea being tested is what the engine controls are for. Engine controls are the switches and devices used to power the engine on and off. Their primary job is to start the engine when you want to operate the vehicle and shut it down when you’re done or need to stop for safety. They’re not used for steering, accelerating, braking, or parking, and they don’t provide warnings about pressures or temperatures—that’s handled by gauges and warning systems. So the best answer is that the engine controls are used to start up and shut down the vehicle’s engine.
