Final answer:

Loss of air pressure from a broken emergency air line will activate the emergency trailer brakes, ensuring the vehicle comes to a stop for safety.

Step-by-step explanation:

If an emergency air line breaks or gets pulled while you are driving, the loss of pressure will cause the emergency trailer brakes to come on.

This is a safety feature designed to bring the vehicle to a stop when there is a sudden loss of air pressure in the brake system.

Breaking the emergency line causes the air pressure to drop, which activates the emergency brakes. Unlike hydraulic systems where a lack of fluid pressure could result in brake failure, the air brake systems on commercial vehicles are designed to engage the brakes in such a situation to prevent the vehicle from moving uncontrollably.
