Final answer:

The tractor protection valve is considered defective if air exhausts from the trailer supply line when the trailer supply valve is closed and the brake pedal is released, as the valve's role is to protect the tractor's air supply.

Explanation:

A tractor protection valve is defective if the trailer supply valve is closed (pulled out) and air exhausts from the trailer supply line with the brake pedal released. This valve is a safety device designed to prevent the loss of air from the tractor in the event that the trailer breaks away or develops a leak. Its function is to protect the air supply of the tractor; thus, it should prevent any air from escaping when the trailer supply valve (also known as the emergency valve) is closed. When the brake pedal is released, there should be no air passing through either the trailer supply line or the trailer service line. If air exhausts from the trailer supply line under these conditions, it is an indication that the tractor protection valve is not functioning correctly and may need maintenance or replacement.
