How is the trailer emergency brake activated?

• A. By turning a knob on the truck dashboard
• B. By pulling out the trailer air supply control
• C. By pressing the foot brake
• D. By removing the key from the ignition

Answer: (B)

The correct method to activate the trailer emergency brake is by pulling out the trailer air supply control. This control is specifically designed to engage the brakes on the trailer in case of an emergency or if the trailer becomes disconnected from the towing vehicle. When the air supply control is pulled out, it allows air to flow into the trailer’s brake system, causing the brakes to be applied. This is crucial for ensuring safety and preventing the trailer from rolling away when not connected to the truck. Understanding the operation of the trailer’s brake system is vital for any commercial driver, as it enhances control over the vehicle combination and ensures compliance with safety standards during transport. Familiarity with this control promotes effective emergency response and reinforces best practices for maintaining vehicle integrity on the road.
